I have some issues to with dovecot 1.1.x, it seams buggish
do you also have this issue?
------------------------------------------------------------
There is a issue with dovecot-antispam and the new dovecot-1.1.x
(dovecot-1.1.1)
The imap server dies when sending mail, the mail goes away but it says
that the imap server has crached in squirrelmail.
I get the standard signal 11 crach in the dovecot loggs
another question?
My dspam users has the email as username somthing at domain.com <http://dovecot.org/cgi-bin/mailman/listinfo/dovecot> and in
dovecot.conf i need to specify the user when training, is there a w
way to get the resiptient address in the dovecot.conf? i am only able to
get %u ie the username ;-(
Could you patch the antispam plugin to be able to take then resiptient
as dspam user? ie the mail address , you can have a option in dovecot
that says use resiptient address as user or something
it would be great if you had time to check this out ;-)
Thanks in advance
