[Dovecot] Deliver prints passwort to the syslog

[Dominik Schulz]

Hi,
I've got the problem that dovecot's deliver prints the authentification 
information to the syslog.

Like this:
Sep 18 12:11:22 mail deliver(user at domain.tld): auth input: 
user=user at domain.tld
Sep 18 12:11:22 mail deliver(user at domain.tld): auth input: password=XXXX
Sep 18 12:11:22 mail deliver(user at domain.tld): auth input: 
home=/home/mail/domain.tld/user
Sep 18 12:11:22 mail deliver(user at domain.tld): auth input: uid=8
Sep 18 12:11:22 mail deliver(user at domain.tld): auth input: gid=8

I guess that it's only a configuration option but right now I can't figure out 
which one I need to change to turn this off.

Any help would be appreciated. Thanks in advance.

Best Regards
Dominik
