I'm having trouble getting SASL support working. The thing is, when i first installed Postfix i did have it working. But i disabled it because i decided not to use it. Now, it appears that i will require it once more. However, working from the H&K Postfix book as a guide, i haven't been able to undo my disabling of it.

Here are (all?) relevant entries from postconf -n

...

smtpd_tls_auth_only = yes


With the above, AUTH will only be offered after a TLS session is started. This setting is used to protect plain-text passwords. You can remove it for testing, but generally is a good thing to have.

Test your connection with openssl's s_client feature - sort of an encrypted telnet - instead of telnet.
Something like:

# openssl s_client -connect localhost:25 -starttls smtp
should start an encrypted connection.


bingo--thanks for that! I'd completely forgotten that TLS was necessary *up front*. Everything's fine.
