3.3 Mail Variables

message-send-mail-function

Function used to send the current buffer as mail. The default is message-send-mail-with-sendmail, or smtpmail-send-it according to the system. Other valid values include message-send-mail-with-mailclient, message-send-mail-with-mh, message-send-mail-with-qmail, message-smtpmail-send-it and feedmail-send-it.

The function message-send-mail-with-sendmail pipes your article to the sendmail binary for further queuing and sending. When your local system is not configured for sending mail using sendmail, and you have access to a remote SMTP server, you can set message-send-mail-function to smtpmail-send-it and make sure to setup the smtpmail package correctly. An example:

(setq message-send-mail-function 'smtpmail-send-it smtpmail-default-smtp-server "YOUR SMTP HOST")

To the thing similar to this, there is message-smtpmail-send-it. It is useful if your ISP requires the POP-before-SMTP authentication. See section `POP before SMTP' in The Gnus Manual.

message-mh-deletable-headers

Most versions of MH doesn't like being fed messages that contain the headers in this variable. If this variable is non-nil (which is the default), these headers will be removed before mailing when sending messages via MH. Set it to nil if your MH can handle these headers.

message-qmail-inject-program

Location of the qmail-inject program.

message-qmail-inject-args

Arguments passed to qmail-inject programs. This should be a list of strings, one string for each argument. It may also be a function.

For e.g., if you wish to set the envelope sender address so that bounces go to the right place or to deal with listserv's usage of that address, you might set this variable to '("-f" "you@some.where").

message-sendmail-f-is-evil

Non-nil means don't add `-f username' to the sendmail command line. Doing so would be even more evil than leaving it out.

message-sendmail-envelope-from

When message-sendmail-f-is-evil is nil, this specifies the address to use in the SMTP envelope. If it is nil, use user-mail-address. If it is the symbol header, use the `From' header of the message.

message-mailer-swallows-blank-line

Set this to non-nil if the system's mailer runs the header and body together. (This problem exists on SunOS 4 when sendmail is run in remote mode.) The value should be an expression to test whether the problem will actually occur.

message-send-mail-partially-limit

The limitation of messages sent as message/partial. The lower bound of message size in characters, beyond which the message should be sent in several parts. If it is nil, the size is unlimited.
