Mail-properties
Description
The SMTP protocol provider supports the following properties, which may be set in the JavaMail Session object.
The properties are always set as strings; the Type column describes how the string is interpreted. For example: use props.put("mail.smtp.port", "888"); to set the mail.smtp.port property, which is of type int.
Note that if you're using the "smtps" protocol to access SMTP over SSL, all the properties would be named "mail.smtps.*".
The following table shows this properties:
| Name | Type | Description |
|---|---|---|
| mail.smtp.user | String | Default user name for SMTP |
| mail.smtp.host | String | The SMTP server to connect to |
| mail.smtp.port | int | The SMTP server port to connect to, if the connect() method doesn't explicitly specify one. Defaults to 25 |
| mail.smtp.connectiontimeout | int | Socket connection timeout value in milliseconds. Default is infinite timeout |
| mail.smtp.timeout | int | Socket I/O timeout value in milliseconds. Default is infinite timeout |
| mail.smtp.from | String | Email address to use for SMTP MAIL command. This sets the envelope return address. Defaults to msg.getFrom() or InternetAddress.getLocalAddress(). NOTE: mail.smtp.user was previously used for this. |
| mail.smtp.localhost | String | Local host name used in the SMTP HELO or EHLO command. Defaults to InetAddress.getLocalHost().getHostName(). Should not normally need to be set if your JDK and your name service are configured properly |
| mail.smtp.localaddress | String | Local address (host name) to bind to when creating the SMTP socket. Defaults to the address picked by the Socket class. Should not normally need to be set, but useful with multi-homed hosts where it's important to pick a particular local address to bind to |
| mail.smtp.localport | int | Local port number to bind to when creating the SMTP socket. Defaults to the port number picked by the Socket class |
| mail.smtp.ehlo | boolean | If false, do not attempt to sign on with the EHLO command. Defaults to true. Normally failure of the EHLO command will fallback to the HELO command; this property exists only for servers that don't fail EHLO properly or don't implement EHLO properly |
| mail.smtp.auth | boolean | If true, attempt to authenticate the user using the AUTH command.
Defaults to false. |
| mail.smtp.auth.mechanisms | String | If set, lists the authentication mechanisms to consider, and the order in which to consider them. Only mechanisms supported by the server and supported by the current implementation will be used. The default is "LOGIN PLAIN DIGEST- MD5 NTLM", which includes all the authentication mechanisms supported by the current implementation |
| mail.smtp.auth.ntlm.domain | String | The NTLM authentication domain |
| mail.smtp.auth.ntlm.flags | int | http://curl.haxx.se/rfc/ntlm.html#theNtlmFlags ] for details. |
| mail.smtp.submitter | String | The submitter to use in the AUTH tag in the MAIL FROM command. Typically used by a mail relay to pass along information about the original submitter of the message. See also the setSubmitter method of SMTPMessage. Mail clients typically do not use this. |
| mail.smtp.dsn.notify | String | The NOTIFY option to the RCPT command. Either NEVER, or some combination of SUCCESS, FAILURE, and DELAY (separated by commas). |
| mail.smtp.dsn.ret | String | The RET option to the MAIL command. Either FULL or HDRS. |
| mail.smtp.allow8bitmime | boolean | If set to true, and the server supports the 8BITMIME extension, text parts of messages that use the "quoted-printable" or "base64" encodings are converted to use "8bit" encoding if they follow the RFC2045 rules for 8bit text. |
| mail.smtp.sendpartial | boolean | If set to true, and a message has some valid and some invalid addresses, send the message anyway, reporting the partial failure with a SendFailedException. If set to false (the default), the message is not sent to any of the recipients if there is an invalid recipient address. |
| mail.smtp.sasl.realm | String | The realm to use with DIGEST-MD5 authentication. |
| mail.smtp.quitwait | boolean | If set to false, the QUIT command is sent and the connection is immediately closed. If set to true (the default), causes the transport to wait for the response to the QUIT command. |
| mail.smtp.reportsuccess | boolean | If set to true, causes the transport to include an SMTPAddressSucceededException for each address that is successful. Note also that this will cause a SendFailedException to be thrown from the sendMessage method of SMTPTransport even if all addresses were correct and the message was sent successfully. |
| mail.smtp.socketFactory | SocketFactory | If set to a class that implements the javax.net.SocketFactory interface, this class will be used to create SMTP sockets. Note that this is an instance of a class, not a name, and must be set using the put method, not the setProperty method. |
| mail.smtp.socketFactory.class | String | If set, specifies the name of a class that implements the javax.net.SocketFactory interface. This class will be used to create SMTP sockets. |
| mail.smtp.socketFactory.fallback | boolean | If set to true, failure to create a socket using the specified socket factory class will cause the socket to be created using the java.net.Socket class. Defaults to true. |
| mail.smtp.socketFactory.port | int | Specifies the port to connect to when using the specified socket factory. If not set, the default port will be used. |
| mail.smtp.ssl.enable | boolean | If set to true, use SSL to connect and use the SSL port by default. Defaults to false for the "smtp" protocol and true for the "smtps" protocol. |
| mail.smtp.ssl.checkserveridentity | boolean | If set to true, check the server identity as specified by RFC 2595. These additional checks based on the content of the server's certificate are intended to prevent man-in-the-middle attacks. Defaults to false. |
| mail.smtp.ssl.trust | String | If set, and a socket factory hasn't been specified, enables use of a MailSSLSocketFactory. If set to "*", all hosts are trusted. If set to a whitespace separated list of hosts, those hosts are trusted. Otherwise, trust depends on the certificate the server presents. |
| mail.smtp.ssl.socketFactory | SSLSocketFactory | If set to a class that extends the javax.net.ssl.SSLSocketFactory class, this class will be used to create SMTP SSL sockets. Note that this is an instance of a class, not a name, and must be set using the put method, not the setProperty method. |
| mail.smtp.ssl.socketFactory.class | String | If set, specifies the name of a class that extends the javax.net.ssl.SSLSocketFactory class. This class will be used to create SMTP SSL sockets. |
| mail.smtp.ssl.socketFactory.port | int | Specifies the port to connect to when using the specified socket factory. If not set, the default port will be used. |
| mail.smtp.ssl.protocols | string | Specifies the SSL protocols that will be enabled for SSL connections. The property value is a whitespace separated list of tokens acceptable to the javax.net.ssl.SSLSocket.setEnabledProtocols method. |
| mail.smtp.ssl.ciphersuites | string | Specifies the SSL cipher suites that will be enabled for SSL connections. The property value is a whitespace separated list of tokens acceptable to the javax.net.ssl.SSLSocket.setEnabledCipherSuites method. |
| mail.smtp.mailextension | String | Extension string to append to the MAIL command. The extension string can be used to specify standard SMTP service extensions as well as vendor-specific extensions. Typically the application should use the SMTPTransport method supportsExtension to verify that the server supports the desired service extension. See RFC 1869 and other RFCs that define specific extensions. |
| mail.smtp.starttls.enable | boolean | If true, enables the use of the STARTTLS command (if supported by the server) to switch the connection to a TLS-protected connection before issuing any login commands. Note that an appropriate trust store must configured so that the client will trust the server's certificate. Defaults to false. |
| mail.smtp.starttls.required | boolean | If true, requires the use of the STARTTLS command. If the server doesn't support the STARTTLS command, or the command fails, the connect method will fail. Defaults to false. |
| mail.smtp.userset | boolean | If set to true, use the RSET command instead of the NOOP command in the isConnected method. In some cases sendmail will respond slowly after many NOOP commands; use of RSET avoids this sendmail issue. Defaults to false. |
| mail.smtp.noop.strict | boolean | If set to true (the default), insist on a 250 response code from the NOOP command to indicate success. The NOOP command is used by the isConnected method to determine if the connection is still alive. Some older servers return the wrong response code on success, some servers don't implement the NOOP command at all and so always return a failure code. Set this property to false to handle servers that are broken in this way. Normally, when a server times out a connection, it will send a 421 response code, which the client will see as the response to the next command it issues. Some servers send the wrong failure response code when timing out a connection. Do not set this property to false when dealing with servers that are broken in this way. |
