I'm getting the 502 error from my postfix server though.

I'm just wondering if anyone else has seen this before. We have an app
that's sending the mail into the postfix boxes, and it doesn't look like
it's sending anything bad. Looks like I'll have to get out the sniffer to
figure out where the problem is coming from.
