qmail smtp authentication

Hi, somebody somehow is authenticating trough my qmail server and sending
mails out.

I would like either to disable SMTP authentication or to understand where
the login/pass is getting from. I have a mysql base and pop3 is going via
qmail-sql.

A log looks like that:

220 myserver ESMTPM
EHLO smtp039.mail.yahoo.comM
250-myserverM
250-AUTH=LOGINM
250-PIPELININGM
250 8BITMIMEM
AUTH LOGINM
334 VXNlcm5hbWU6M
d2VibWFzdGVyM
334 UGFzc3dvcmQ6M
d2VibWFzdGVyM
235 go aheadM

As fas as i understand, the user/pass is d2VibWFzdGVy/d2VibWFzdGVy?

tnx & br,
Greg

Yup. In this case, those both come out to "webmaster". It's just
Base-64 encoded text. The first "334" line is "Username:", the
second is "Password:".
