I've heard from a couple of people that the PIX will remap 587 (and 25) to oddball ports if you fiddle the config just right. Given all the other bogosity that box does with SMTP I wonder if there's truth to the rumour. (I haven't found anyone who can reproduce this on demand, so it's still apocryphal for now.)
I've heard some people say that reproducing totally compliant SMTP behavior on those boxes on demand is apocryphal as well. :) (I have to admit I haven't actually tracked a user complaint down to a misbehaving PIX in a year or two, but I can't say if the software has gotten better or if its market share is just small enough to fly under my radar - the type of people who send e-mail from behind a PIX don't interact with my users all that often)
