do you know the "fw monitor"-command?
I would check what happenes to the packets arriving at the firewall ...
is this mailserver the only machine in this DMZ or are there others? maybe you have a layer-2-problem?
do smtp-connections in the same subnet work fine?

Hy Reinhard,
I don't use any smtp-ressource and in the log there are no droped connection. The mailserver send two stmp packets and the fourth packet doesn't arrive me from the client mailserver. I see nothing in the log, only the first packet of smtp that is accept.
What can I do?
