Thank you for the quick reply. Last night I managed to get it running
using the cyrdeliver tool, found something about it in a debian-forum.
But I will also have a look at the -a option of lmtpd to see if it works
for me.
Using dovecot unfortunatelly seems not be an option as I was told to do
it using exim/cyrus/sasl. I could have a look at dovecot but would have
to argue with my bosses why I want to use it. So if I'm not running into
any more serious problems with the smtp setup, exim will be the way to go.
Best regards,
