AWU is on Debian Wheezy (7.0) now. Everything went great, except for getting Postfix to connect to saslauthd for authentication. I had this bit in /etc/fstab from $DEITY-knows-where:
/var/run/saslauthd /var/spool/postfix/var/run/saslauthd bind bind 0 0
It’s a hack to remount /var/run/saslauthd on /var/spool/postfix/var/run/saslauthd so that the chrooted postfix can find the “mux” socket. Run as root:
service saslauthd stop (this will probably fail, but just to be sure saslauthd is well and truly dead)
umount /var/spool/postfix/var/run/saslauthd
Then nuke that line from /etc/fstab! You don’t need this hack any more…just make sure the last line in /etc/default/saslauthd is:
OPTIONS=”-c -m /var/spool/postfix/var/run/saslauthd” (comment out the other OPTIONS line)
Then, as root:
service saslauthd start
Postfix will now accept mail from your clients again.
