I have a mailserver running postfix and spamassassin. I have a user 'user1' and
an alias 'alias1', like this in /etc/aliases:
alias1: user1
I have spamassassin configured with bayes filtering enabled, but when I receive
mail at ali...@mydomain.com, spamassassin appears to not be able to find the
user 'alias1' (when it should be looking for the user 'user1'). This makes the
suid fail which makes the per-user bayes database for 'user1' not useable when
receiving mail sent to 'alias1'. The log lines look like:
Mar 14 21:39:23 mydomain spamd[2552]: spamd: connection from localhost

/usr/bin/procmail -t -a "$EXTENSION")
How do people normally work around this? Is there some way to indicate to
spamassassin that it should check /etc/aliases for the user-mapping if the user
isn't found?
Relevant configuration follows. In /etc/spamassassin/local.cf:
use_bayes 1
bayes_auto_learn 1
skip_rbl_checks 0
use_razor2 1
razor_config /etc/razor/razor-agent.conf
spamassassin's cmdline looks like this:
/usr/sbin/spamd --create-prefs --max-children 2 --helper-home-dir -d
--pidfile=/var/run/spamd.pid
/usr/sbin/spamass-milter -P /var/run/spamass/spamass.pid -f -p
/var/spool/postfix/spamass/spamass.sock -u spamass-milter -i 127.0.0.1 -I -r 14
-m
And in /etc/postfix.conf:
smtpd_milters = unix:/spamass/spamass.sock
