AW: Logging problems + authentication problems

[Herbert Muller]

After some more try and error I reached a point where I get the following
error messages from postfix/smtpd:

Jan 20 04:22:56 szse postfix/smtpd[3948]: sql auxprop plugin using mysql
engine

-> I think that's when postfix restarts smtpd.

And later:
Jan 20 10:38:47 szse postfix/smtpd[4305]: sql plugin Parse the username
mail at example.de 
Jan 20 10:38:47 szse postfix/smtpd[4305]: sql plugin try and connect to a
host 
Jan 20 10:38:47 szse postfix/smtpd[4305]: sql plugin trying to open db
'mail' on host '127.0.0.1' 
Jan 20 10:38:47 szse postfix/smtpd[4305]: sql plugin could not connect to
host 127.0.0.1
Jan 20 10:38:47 szse postfix/smtpd[4305]: sql plugin couldn't connect to any
host

Maybe somebody can figure out from that messages, what I can do to solve my
problem.

Probably the other messages

Jan 20 10:38:47 szse postfix/smtpd[4305]: warning:
pD95F4F9B.dip.t-dialin.net[217.95.79.155]: SASL LOGIN authentication failed
Jan 20 10:38:47 szse postfix/smtpd[4305]: >
pD95F4F9B.dip.t-dialin.net[217.95.79.155]: 535 Error: authentication failed

are the consequence.
