...: passdb(toshiba1 at domain,8.8.8.8,master): Attempted master login with no master passdbs (trying to log in as user: plain) The connections come from an old (embedded) mail client in a printer-fax machine. I googled for this specific error, but I only found info about old clients using "user\0user\0pass" string incorrectly during authentication, which caused a problem for earlier, development versions of dovecot. Actually, I recently migrated from 1.2 to 2.2.4 exactly to alleviate this situation, but the errors persist. Is there a way to remove the problem or work around it? Regards, G...

...ble the Dovecot auth log line is caused > by a Postfix connection attempt? That would have been my first guess. Why don't you actually try it out (i.e. login in to SMTP with bad credentials) and see if the mysterious log entry appears. # Create bogus SMTP auth string AUTH=`echo "\0user\0badpassword\c" | openssl enc -base64` # SMTP session commands echo "EHLO test.client.helo\nAUTH PLAIN $PW\nQUIT" >data # Use whichever command your Postfix supports "250-AUTH PLAIN" # - if you greet pause, you'll have to enter data manually netcat -C mai...

Hi, I'm working on "avelsieve" SqurrelMail plug-in to implement SIEVE "file" back end for dovecot. 1. My be someone my explain me, how to use client auth socket to authenticate against dovecot-auth unix socket. As fas as I understood login must be sent in form "user\0\user\0password" as base64 encoded string. pp code (I'm using socket used by postfix auth):

...ndDovecotSASL 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...
