dovecot

Hi List,

I just updated an old sendmail installation to a modern postfix/dovecot system 
with mysql backend. Everything works fine but SMTP-AUTH fails with some clients.

The problem is, that with PLAIN (old) clients send the base64 coded form: 
USERNAME\0USERNAME\0PASSWORD which, as i understand dovecot interprets as 
MASTERUSER\0USERNAME\PASSWORD. New clients send \0USERNAME\0PASSWORD which 
works fine. I don`t like to use masterusers, because then everyone would be 
able to log in as someone else. 

When i don`t have a passdb with master=yes in my dovecot.conf, Dovecot complains
auth(default): passdb([EMAIL PROTECTED],master): Attempted master login with no 
master passdbs

If i create a passdb with contains everyone, everyone may look into other 
mailboxes. No good idea.

I can`t change the old clients, but for now, i don`t know, what i am doing 
wrong or how to correct it. No real HowTo for my setup on the net, it seems 
that everyone uses cyrus-sasl.

May anybody help, because i don`t like to switch my setup or use 2 auth daemons.

My System:
Debian Etch, postfix (2.3.7-3), dovecot (1.0.rc15-2)

Best wishes,

Ingo Reimann
