A month ago (or more) I had a problem with my email being rejected. It turned
out that if you send from a machine that is not listed as an MX for your
domain then they reject your mail ... of course they don't seem to be
rejecting it in your case, and I don't know if you're sending using
@istop.com or @xtrinsic.com.
In my case my MX was listed as georgetown.wehave.net but reverse dns had it
named drcrane.tor.istop.com. It took quite a few emails to support for me to
figure out what was going on ... mainly because I failed to read between the
lines ;-) They changed my reverse dns and are now happily (I think)
accepting my email.
Note, this wasn't simply a matter of A and PTR records being mismatched (they
actually weren't) they thought that only mailservers listed to receive mail
(MX) should have the right to send mail ... might be a very good anti-spam
measure but I would expect the false positives are high.
