I have an issue with only a few domains sending mail to a company's exchang=
e server.
Topology is as follows:
Internet -> PIX -> logical interface / vlan -> HP switch (interface tagged =
into applicable vlan) -> ESXi server -> vm (ASSP/CentOS Postfix MTA) -> HP =
switch (out of vlan) -> physical HP server with E2003.
Mail comes in, ASSP logs it, postfix logs it, queues it, attempts delivery =
to my exchange server and somewhere com gets mangled. I can't tell what's w=
rong at the postfix side, but the exchange server doesn't even log it despi=
te the mail getting queued and released?
How can I dump this interaction and more specifically sort it to see only t=
hat transaction. Server is busy, there would be a lot of data on a continuo=
us dump. Given the topology there is room for much issues and I don't doubt=
the issue being from ESX forward (seen silly network issues on ESX before)=
.
Thanks for any input!
