OK, having successfully got SASL authentication working via Dovecot (as per Wietse's helpful comments on my previous post), I now have another query which I can't seem to find the answer to either by reading the Postfix documentation or Googling.

What I want to do is configure Postfix so that authentication is required on port 587 (submission port), but not available on port 25 (ie, users on port 25 cannot authenticate).


in the submission service (in master.cf), use something like:

submission ... ... smtpd
    ...
    -o smtpd_sasl_auth_enable=${submission_sasl_auth_enable}


and in main.cf

submission_sasl_auth_enable = yes

(don't enable smtpd_sasl_auth_enable as this one applies to any smtpd listener).

Excellent, that's just what I needed, thanks.
