Created May 7, 2012
John Zukowski The following is taken from the javadoc files for the com.sun.mail.pop3 package in JavaMail 1.2:
| 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. Defaults to InetAddress.getLocalHost().getHostName(). Should not normally need to be set if your JDK and your name service are configured properly. |
| 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.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. |
