procmail

+If you use procmail for your main mailbox, PLEASE, erase your .forward +file and put a .procmailrc in its place instead. This feature has been +supported on debian.org machines for a good while now, and will continue to be +supported. + +

+The correct way to invoke procmail for extension addresses is "|/usr/bin/procmail [options]" +Ignore the IFS=".." stuff in the procmail man page. + +

MailBox formats

+Emails can be saved to mailboxes or maildirs by using the correct lines in a +.forward file: +

+Mailbox format files "/debian/home/foo/Mbox" +
Maildir format files "/debian/home/foo/MDir/" + +

+To deliver to /var/spool/mail/foo use a construct like '|/usr/bin/procmail +-m /dev/null'. Putting the mailbox path will not work. You must use +absolute paths for mailboxes, qmail-like ./ paths are not supported by +Exim. + +

+Also, 'Exim Filter' files are deliberately turned off. + +
