Ah. This is very slow.
- I agree ;-)

Perform some network tests, e.g. us pchar et.al.
 - well I did and funnily enough when I did a logging with ethereal the
client's packets where somehow tiny bits and pieces compared to the
logging I did on a MUA directly on the server. We thought that this
might cause the "slow" behaviour because the requests to send the mail
on the smtp port are numerous but very small ... Hmmm. I suggeted that
it could be a problem caused by the MUA on the clients (old version of
Eudora Light).
I will be back tomorrow with the logs and the main.cf.
Best regards
