I try to setup my postfix smtp with sasl auth. It seems to be working when I check it with telnet on the local server.

ouput:

# telnet mail.domain.tld smtp
Trying 37.34.52.199...
Connected to mail.domain.tld.
Escape character is '^]'.
220 mail.domain.tld ESMTP Postfix
ehlo domain.tld
250-mail.domain.tld
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

But When I try to test the auth to login, I am stuck with the username:

auth login
334 VXNlcm5hbWU6
dXNlcm5hbWUK
535 5.7.8 Error: authentication failed: VXNlcm5hbWU6

Username created as follow:

 # echo 'username' | base64

I am sure the user exists, I logged in to IMAP with the same user aswel.

postconf output:

broken_sasl_auth_clients = yes

Thank you!

  • Do your logs mention anything useful? and is dovecot set up correctly to provide the authentication listener at `/var/spool/postfix/private/auth`? – HBruijn Feb 10 '14 at 11:33

I would suggest to use swaks to test postfix.

swaks -s mail.domain.tld --to user@exmaple.net --from user@domain.tld --auth LOGIN --auth-user user@domain.tld
