In the original scenario, Exchange was in the same network with Postfix (both in dmz). For a reason, when applied on the customer premises, dhcp wouldn't go through for the local workstations, so exchange was moved to the local zone. To be honest, the testing didn't include large attachments (if any), don't ask me why, I'm sure I'm going to look into it, definitely next time.
So, to be specific Zone Net (external set of 16ips MASK 255.255.255.240 ) Zone dmz (network 192.168.100.0 MASK 255.255.255.0) Zone loc (network 192.168.1.0 MASK 255.255.255.0) The vms run on a Supermicro SuperServer 7046A-HR+F ( http://www.supermicro.com/products/system/4U/7046/SYS-7046A-HR_.cfm?IPMI=Y ) Just a reminder, few e-mails don't go through, but they add up as days go by. Small e-mails go through, attachments, with specific servers don't (some even between postfix and my own exchange!). I should be looking onto your suggestions tomorrow (gmt +2:00 here), I will definitely get back to you, and whoever tails this mess.
