Postfix + SMTP-AUTH

I finally found a good blog post on the subject of getting Postfix to do SMTP-AUTH via SASL.

I went one step further, and instead of moving /var/run/saslauthd/ to the Postfix chroot, I did a bind mount:


/var/run/saslauthd /var/spool/postfix/var/run/saslauthd none bind 0     0

Postfix was announcing methods like CRAM-MD5 which can’t be supported by the PAM backend, so I restricted them down to PLAIN and LOGIN (over TLS only, obviously):


pwcheck_method: saslauthd
mech_list: plain login

Now, it’s working nicely, and I can IMAPS and SMTP-AUTH-TLS to my mail server from anywhere.
