Hello, we're trying to setup a platform with authenticated SMTP with exim and relying on dovecot as auth agent.
We've read http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL and so made the changes mentioned there, also setting
auth_mechanisms = plain login
in conf.d/10-auth.conf .
With this setup, we're able to use AUTH LOGIN method on an SMTP session, but using AUTH PLAIN fails.
What we receive in the SMTP session is:
auth plain echo -e -n \0user\0password' | mimencode`
535 Incorrect authentication data
(it's actually the output of that command that we put there), and in the dovecot log we see:
2012-05-24 15:04:20 auth: Debug: client in: AUTH 1 PLAIN service=smtp secured rip=127.0.0.1 lip=127.0.0.1 nologin resp=<hidden> 2012-05-24 15:04:20 auth: Info: plain(?,127.0.0.1): invalid input
Do you know where we can look to resolve this problem? If you need any further information/test feel free to ask.
Thanks in advance?
