Properties used to connect to the SMTP server in JavaMail

Property	Overview	Details
6.2.1 mail.smtp.allow8bitmime	Supporting 8BITMIME extension	If this value is set to `true` and the server supports the 8BITMIME extension, then the text parts of the messages that use the quoted-printable or base64 encodings are converted to use the 8-bit encoding.

6.2.3 mail.smtp.connectiontimeout	Specifying socket connection time-out value in milliseconds	`mail.smtp.connectiontimeout` specifies the socket connection time-out value in milliseconds.
6.2.4 mail.smtp.ehlo	Attempting to logon with the `EHLO` command	When `mail.smtp.ehlo` is set to `false`, it does not attempt to logon with the `EHLO` command.
6.2.5 mail.smtp.localhost	Apecifying name of localhost	`mail.smtp.localhost` specifies the name of the localhost that is used in the `SMTP HELO` or `EHLO` commands.
6.2.6 mail.smtp.sendpartial	Sending mail only to valid address	If set to `true` and the message has both valid and invalid addresses, then the message is sent and a partial failure is reported with the SendFailedException exception.
6.2.7 mail.smtp.ssl.protocols	Specifying SSL protocols that are enabled for SSL connections	`mail.smtp.ssl.protocols` specifies the SSL protocols that are enabled for SSL connections.
6.2.8 mail.smtp.timeout	Specifying socket read time-out value in milliseconds	`mail.smtp.timeout` specifies the socket read time-out value in milliseconds.
6.2.9 mail.smtp.writetimeout	Specifying socket write time-out value in milliseconds	`mail.smtp.writetimeout` specifies the socket write time-out value in milliseconds.

Properties used to connect to the IMAP server in JavaMail

Property	Overview	Details
6.3.1 mail.imap.connectiontimeout	Specifying socket connection time-out value in milliseconds	`mail.imap.connectiontimeout` specifies the socket connection time-out value in milliseconds.
6.3.2 mail.imap.fetchsize	Specifying partial fetch size in bytes	`mail.imap.fetchsize` specifies the partial fetch size in bytes.
6.3.3 mail.imap.peek	Avoiding setting SEEN flag on messages	When `mail.imap.peek` is set to `true`, it uses the `IMAP PEEK` option while fetching body parts, to avoid setting the SEEN flag on messages.
6.3.4 mail.imap.ssl.protocols	Specifying SSL protocols that are enabled for SSL connections	`mail.imap.ssl.protocols` specifies the SSL protocols that are enabled for SSL connections.
6.3.5 mail.imap.statuscachetimeout	Specifying time-out value in milliseconds for cache of `STATUS` command response	`mail.imap.statuscachetimeout` specifies the time-out value in milliseconds for the cache of the `STATUS` command response.
6.3.6 mail.imap.timeout	Specifying socket read time-out value in milliseconds	`mail.imap.timeout` specifies the socket read time-out value in milliseconds.
6.3.7 mail.imap.writetimeout	Specifying socket write time-out value in milliseconds	`mail.imap.writetimeout` specifies the socket write time-out value in milliseconds.
