7.1.5 Sending mail by POP-before-SMTP

You can send mail by POP-before-SMTP with this single line:

(setq wl-draft-send-mail-function 'wl-draft-send-mail-with-pop-before-smtp)

Configure the following variables if you need.

wl-pop-before-smtp-user

The POP user name for POP-before-SMTP authentication. If unset, elmo-pop3-default-user is used.

wl-pop-before-smtp-server

The POP server name for POP-before-SMTP authentication. If unset, elmo-pop3-default-server is used.

wl-pop-before-smtp-authenticate-type

The POP authentication method for POP-before-SMTP authentication. If unset, elmo-pop3-default-authenticate-type is used.

wl-pop-before-smtp-port

The POP port number for POP-before-SMTP authentication. If unset, elmo-pop3-default-port is used.

wl-pop-before-smtp-stream-type

If ssl, POP connection is established using SSL. If starttls, STARTTLS (RFC2595) connection will be established. If unset, elmo-pop3-default-stream-type is used.

If variables for POP-before-SMTP (wl-pop-before-smtp-*) are unset, settings for POP folders (elmo-pop3-default-*) are used. Therefore, if SMTP server and POP server are actually the same, and if POP folder per default (such as `&') is available, no settings are required.
