mostly means the incomming mailserver stops deliver in by timeout this may have many reasons, i.e is there some firewall with smtp inspection involved and/or some network problem if this is a new problem ask for new hardware/software setup the network way up to the sender perhaps you have to do network analyse to find the truth by the way what is this warning: header...? maybe you do to much header checking ( i.e in header_checks ) this slows down your system too, and may break deliver in also look for some header checking software on your server ( which does not report to your log etc ) -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
