By default its assumed the message id is unique and has no value to be kept in the repository because the mail message will be marked as seen/moved or deleted to prevent it from being consumed again. And therefore having the message id stored in the idempotent repository has little value. However this option allows to store the message id for whatever reason you may have. searchTerm: kind: parameter group: filter label: consumer,filter type: object javaType: javax.mail.search.SearchTerm prefix: searchTerm. multiValue: true deprecated: false secret: false description: Refers to a javax.mail.search.SearchTerm which allows to filter mails based on search criteria such as subject body from sent after a certain date etc. backoffErrorThreshold: kind: parameter group: scheduler label: consumer,scheduler type: integer javaType: int optionalPrefix: consumer. deprecated: false secret: false description: The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in. backoffIdleThreshold: kind: parameter group: scheduler label: consumer,scheduler type: integer javaType: int optionalPrefix: consumer. deprecated: false secret: false description: The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. backoffMultiplier: kind: parameter group: scheduler label: consumer,scheduler type: integer javaType: int optionalPrefix: consumer. deprecated: false secret: false description: To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row.

Maven users will need to add the following dependency to their `pom.xml` for this component: [source,xml] ------------------------------------------------------------ org.apache.camel camel-mail x.x.x ------------------------------------------------------------ WARNING: *Geronimo mail .jar* We have discovered that the geronimo mail `.jar` (v1.6) has a bug when polling mails with attachments. It cannot correctly identify the `Content-Type`. So, if you attach a `.jpeg` file to a mail and you poll it, the `Content-Type` is resolved as `text/plain` and not as `image/jpeg`. For that reason, we have added an `org.apache.camel.component.ContentTypeResolver` SPI interface which enables you to provide your own implementation and fix this bug by returning the correct Mime type based on the file name. So if the file name ends with `jpeg/jpg`, you can return `image/jpeg`. You can set your custom resolver on the `MailComponent` instance or on the `MailEndpoint` instance. TIP: *POP3 or IMAP* POP3 has some limitations and end users are encouraged to use IMAP if possible. INFO: *Using mock-mail for testing* You can use a mock framework for unit testing, which allows you to test without the need for a real mail server. However you should remember to not include the mock-mail when you go into production or other environments where you need to send mails to a real mail server. Just the presence of the mock-javamail.jar on the classpath means that it will kick in and avoid sending the mails. [[Mail-URIformat]] URI format ^^^^^^^^^^ Mail endpoints can have one of the following URI formats (for the protocols, SMTP, POP3, or IMAP, respectively): [source,java] --------------------------------------- smtp://[username@]host[:port][?options] pop3://[username@]host[:port][?options] imap://[username@]host[:port][?options] --------------------------------------- The mail component also supports secure variants of these protocols (layered over SSL). You can enable the secure protocols by adding `s` to the scheme: [source,java] ---------------------------------------- smtps://[username@]host[:port][?options] pop3s://[username@]host[:port][?options] imaps://[username@]host[:port][?options] ---------------------------------------- You can append query options to the URI in the following format, `?option=value&option=value&...` [[Mail-Component-Options]] ^^^^^^^^^^^^^^^^^^^^^^^^^^ // component options: START The Mail component supports 2 options which are listed below. {% raw %} [width="100%",cols="2,1m,7",options="header"] |======================================================================= | Name | Java Type | Description | configuration | MailConfiguration | Sets the Mail configuration | contentTypeResolver | ContentTypeResolver | Resolver to determine Content-Type for file attachments. |======================================================================= {% endraw %} // component options: END [[Mail-Endpoint-Options]] ^^^^^^^^^^^^^^^^^^^^^^^^^^ // endpoint options: START The Mail component supports 63 endpoint options which are listed below: {% raw %} [width="100%",cols="2,1,1m,1m,5",options="header"] |======================================================================= | Name | Group | Default | Java Type | Description | host | common | | String | *Required* The mail server host name | port | common | | int | The port number of the mail server | bridgeErrorHandler | consumer | false | boolean | Allows for bridging the consumer to the Camel routing Error Handler which mean any exceptions occurred while the consumer is trying to pickup incoming messages or the likes will now be processed as a message and handled by the routing Error Handler.

[[Mail-UsingtheJSSEConfigurationUtility]] Using the JSSE Configuration Utility ++++++++++++++++++++++++++++++++++++ As of *Camel 2.10*, the mail component supports SSL/TLS configuration through the link:camel-configuration-utilities.html[Camel JSSE Configuration Utility].?? This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels.?? The following examples demonstrate how to use the utility with the mail component. [[Mail-Programmaticconfigurationoftheendpoint]] Programmatic configuration of the endpoint [source,java] ---------------------------------------------------------------------------------------------------------------------------------- KeyStoreParameters ksp = new KeyStoreParameters(); ksp.setResource("/users/home/server/truststore.jks"); ksp.setPassword("keystorePassword"); TrustManagersParameters tmp = new TrustManagersParameters(); tmp.setKeyStore(ksp); SSLContextParameters scp = new SSLContextParameters(); scp.setTrustManagers(tmp); Registry registry = ... registry.bind("sslContextParameters", scp); ... from(...)     .to("smtps://smtp.google.com?username=user@gmail.com&password=password&sslContextParameters=#sslContextParameters"); ---------------------------------------------------------------------------------------------------------------------------------- [[Mail-SpringDSLbasedconfigurationofendpoint]] Spring DSL based configuration of endpoint [source,xml] --------------------------------------------------------------------------------------------------------------------------- ... ... ... ... --------------------------------------------------------------------------------------------------------------------------- [[Mail-ConfiguringJavaMailDirectly]] Configuring JavaMail Directly +++++++++++++++++++++++++++++ Camel uses SUN JavaMail, which only trusts certificates issued by well known Certificate Authorities (the default JVM trust configuration). If you issue your own certificates, you have to import the CA certificates into the JVM's Java trust/key store files, override the default JVM trust/key store files (see `SSLNOTES.txt` in JavaMail for details). [[Mail-MailMessageContent]] Mail Message Content ^^^^^^^^^^^^^^^^^^^^ Camel uses the message exchange's IN body as the http://java.sun.com/javaee/5/docs/api/javax/mail/internet/MimeMessage.html[MimeMessage] text content. The body is converted to `String.class`. Camel copies all of the exchange's IN headers to the http://java.sun.com/javaee/5/docs/api/javax/mail/internet/MimeMessage.html[MimeMessage] headers. The subject of the http://java.sun.com/javaee/5/docs/api/javax/mail/internet/MimeMessage.html[MimeMessage] can be configured using a header property on the IN message. The code below demonstrates this: The same applies for other MimeMessage headers such as recipients, so you can use a header property as `To`: *Since Camel 2.11* When using the MailProducer the send the mail to server, you should be able to get the message id of the http://java.sun.com/javaee/5/docs/api/javax/mail/internet/MimeMessage.html[MimeMessage] with the key `CamelMailMessageId` from the Camel message header. [[Mail-Headerstakeprecedenceoverpre-configuredrecipients]] Headers take precedence over pre-configured recipients ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The recipients specified in the message headers always take precedence over recipients pre-configured in the endpoint URI. The idea is that if you provide any recipients in the message headers, that is what you get. The recipients pre-configured in the endpoint URI are treated as a fallback. In the sample code below, the email message is sent to `davsclaus@apache.org`, because it takes precedence over the pre-configured recipient, `info@mycompany.com`. Any `CC` and `BCC` settings in the endpoint URI are also ignored and those recipients will not receive any mail. The choice between headers and pre-configured settings is all or nothing: the mail component _either_ takes the recipients exclusively from the headers or exclusively from the pre-configured settings. It is not possible to mix and match headers and pre-configured settings. [source,java] ------------------------------------------------------------------------------------------------------------ Map headers = new HashMap(); headers.put("to", "davsclaus@apache.org"); template.sendBodyAndHeaders("smtp://admin@localhost?to=info@mycompany.com", "Hello World", headers); ------------------------------------------------------------------------------------------------------------ [[Mail-Multiplerecipientsforeasierconfiguration]] Multiple recipients for easier configuration ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ It is possible to set multiple recipients using a comma-separated or a semicolon-separated list. This applies both to header settings and to settings in an endpoint URI. For example: [source,java] ------------------------------------------------------------------------------------------------ Map headers = new HashMap(); headers.put("to", "davsclaus@apache.org ; jstrachan@apache.org ; ningjiang@apache.org"); ------------------------------------------------------------------------------------------------ The preceding example uses a semicolon, `;`, as the separator character. [[Mail-Settingsendernameandemail]] Setting sender name and email ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ You can specify recipients in the format, `name `, to include both the name and the email address of the recipient. For example, you define the following headers on the a link:message.html[Message]: [source,java] --------------------------------------------------------- Map headers = new HashMap(); map.put("To", "Claus Ibsen "); map.put("From", "James Strachan "); map.put("Subject", "Camel is cool"); --------------------------------------------------------- [[Mail-JavaMailAPI(exSUNJavaMail)]] JavaMail API (ex SUN JavaMail) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ https://java.net/projects/javamail/pages/Home[JavaMail API] is used under the hood for consuming and producing mails. + We encourage end-users to consult these references when using either POP3 or IMAP protocol. Note particularly that POP3 has a much more limited set of features than IMAP. * https://javamail.java.net/nonav/docs/api/com/sun/mail/pop3/package-summary.html[JavaMail POP3 API] * https://javamail.java.net/nonav/docs/api/com/sun/mail/imap/package-summary.html[JavaMail IMAP API] * And generally about the https://javamail.java.net/nonav/docs/api/javax/mail/Flags.html[MAIL Flags] [[Mail-Samples]] Samples ^^^^^^^ We start with a simple route that sends the messages received from a JMS queue as emails. The email account is the `admin` account on `mymailserver.com`. [source,java] ------------------------------------------------------------------------------------- from("jms://queue:subscription").to("smtp://admin@mymailserver.com?password=secret"); ------------------------------------------------------------------------------------- In the next sample, we poll a mailbox for new emails once every minute. Notice that we use the special `consumer` option for setting the poll interval, `consumer.delay`, as 60000 milliseconds = 60 seconds. [source,java] ------------------------------------------------------- from("imap://admin@mymailserver.com password=secret&unseen=true&consumer.delay=60000") .to("seda://mails"); ------------------------------------------------------- In this sample we want to send a mail to multiple recipients: [[Mail-Sendingmailwithattachmentsample]] Sending mail with attachment sample ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ WARNING: *Attachments are not support by all Camel components* The _Attachments API_ is based on the Java Activation Framework and is generally only used by the Mail API. Since many of the other Camel components do not support attachments, the attachments could potentially be lost as they propagate along the route. The rule of thumb, therefore, is to add attachments just before sending a message to the mail endpoint. The mail component supports attachments. In the sample below, we send a mail message containing a plain text message with a logo file attachment. [[Mail-SSLsample]] SSL sample ^^^^^^^^^^ In this sample, we want to poll our Google mail inbox for mails. To download mail onto a local mail client, Google mail requires you to enable and configure SSL. This is done by logging into your Google mail account and changing your settings to allow IMAP access. Google have extensive documentation on how to do this. [source,java] ------------------------------------------------------------------------------------- from("imaps://imap.gmail.com?username=YOUR_USERNAME@gmail.com&password=YOUR_PASSWORD" + "&delete=false&unseen=true&consumer.delay=60000").to("log:newmail"); ------------------------------------------------------------------------------------- The preceding route polls the Google mail inbox for new mails once every minute and logs the received messages to the `newmail` logger category. + Running the sample with `DEBUG` logging enabled, we can monitor the progress in the logs: [source,java] ------------------------------------------------------------------------------------------------------------------------------------------------------------------ 2008-05-08 06:32:09,640 DEBUG MailConsumer - Connecting to MailStore imaps//imap.gmail.com:993 (SSL enabled), folder=INBOX 2008-05-08 06:32:11,203 DEBUG MailConsumer - Polling mailfolder: imaps//imap.gmail.com:993 (SSL enabled), folder=INBOX 2008-05-08 06:32:11,640 DEBUG MailConsumer - Fetching 1 messages.

First, we define a route to poll the mailbox. As this sample is based on google mail, it uses the same route as shown in the SSL sample: [source,java] --------------------------------------------------------------------------------------- from("imaps://imap.gmail.com?username=YOUR_USERNAME@gmail.com&password=YOUR_PASSWORD" + "&delete=false&unseen=true&consumer.delay=60000").process(new MyMailProcessor()); --------------------------------------------------------------------------------------- Instead of logging the mail we use a processor where we can process the mail from java code: [source,java] --------------------------------------------------------------------------------- public void process(Exchange exchange) throws Exception { // the API is a bit clunky so we need to loop Map attachments = exchange.getIn().getAttachments(); if (attachments.size() > 0) { for (String name : attachments.keySet()) { DataHandler dh = attachments.get(name); // get the file name String filename = dh.getName(); // get the content and convert it to byte[] byte[] data = exchange.getContext().getTypeConverter() .convertTo(byte[].class, dh.getInputStream()); // write the data to a file FileOutputStream out = new FileOutputStream(filename); out.write(data); out.flush(); out.close(); } } } --------------------------------------------------------------------------------- As you can see the API to handle attachments is a bit clunky but it's there so you can get the `javax.activation.DataHandler` so you can handle the attachments using standard API. [[Mail-Howtosplitamailmessagewithattachments]] How to split a mail message with attachments ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ In this example we consume mail messages which may have a number of attachments. What we want to do is to use the link:splitter.html[Splitter] EIP per individual attachment, to process the attachments separately. For example if the mail message has 5 attachments, we want the link:splitter.html[Splitter] to process five messages, each having a single attachment. To do this we need to provide a custom link:expression.html[Expression] to the link:splitter.html[Splitter] where we provide a List that contains the five messages with the single attachment. The code is provided out of the box in Camel 2.10 onwards in the `camel-mail` component. The code is in the class: `org.apache.camel.component.mail.SplitAttachmentsExpression`, which you can find the source code https://svn.apache.org/repos/asf/camel/trunk/components/camel-mail/src/main/java/org/apache/camel/component/mail/SplitAttachmentsExpression.java[here] In the Camel route you then need to use this link:expression.html[Expression] in the route as shown below: If you use XML DSL then you need to declare a method call expression in the link:splitter.html[Splitter] as shown below [source,xml] --------------------------------------------------------------------------------- --------------------------------------------------------------------------------- ?? From Camel 2.16 onwards you can also split the attachments as byte[] to be stored as the message body. This is done by creating the expression with boolean true [source,java] -------------------------------------------------------------------- SplitAttachmentsExpression split = SplitAttachmentsExpression(true); -------------------------------------------------------------------- And then use the expression with the splitter eip. [[Mail-UsingcustomSearchTerm]] Using custom SearchTerm ^^^^^^^^^^^^^^^^^^^^^^^ *Available as of Camel 2.11* You can configure a `searchTerm` on the `MailEndpoint` which allows you to filter out unwanted mails. For example to filter mails to contain Camel in either Subject or Text you can do as follows: [source,xml] ------------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------------- Notice we use the `"searchTerm.subjectOrBody"` as parameter key to indicate that we want to search on mail subject or body, to contain the word "Camel". + The class `org.apache.camel.component.mail.SimpleSearchTerm` has a number of options you can configure: Or to get the new unseen emails going 24 hours back in time you can do. Notice the "now-24h" syntax. See the table below for more details. [source,xml] -------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------- You can have multiple searchTerm in the endpoint uri configuration. They would then be combined together using AND operator, eg so both conditions must match. For example to get the last unseen emails going back 24 hours which has Camel in the mail subject you can do: [source,xml] --------------------------------------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------------------------------------- The `SimpleSearchTerm` is designed to be easily configurable from a POJO, so you can also configure it using a style in XML [source,java] --------------------------------------------------------------------------------- --------------------------------------------------------------------------------- You can then refer to this bean, using #beanId in your Camel route as shown: [source,xml] ------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------- In Java there is a builder class to build compound `SearchTerms` using the `org.apache.camel.component.mail.SearchTermBuilder` class. This allows you to build complex terms such as: [source,java] -------------------------------------------------------------- // we just want the unseen mails which is not spam SearchTermBuilder builder = new SearchTermBuilder(); builder.unseen().body(Op.not, "Spam").subject(Op.not, "Spam") // which was sent from either foo or bar .from("foo@somewhere.com").from(Op.or, "bar@somewhere.com"); // .. and we could continue building the terms SearchTerm term = builder.build(); -------------------------------------------------------------- [[Mail-SeeAlso]] See Also ^^^^^^^^ * link:configuring-camel.html[Configuring Camel] * link:component.html[Component] * link:endpoint.html[Endpoint] * link:getting-started.html[Getting Started]
