I have an issue with only a few domains sending mail to a company's exchange
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
wrong at the postfix side, but the exchange server doesn't even log it
despite the mail getting queued and released?
How can I dump this interaction and more specifically sort it to see only that
transaction. Server is busy, there would be a lot of data on a continuous 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!
