AFAIK Gmail's rejection algorithm (like most SPAM systems nowadays)
is not deterministic nor documented, so until proof that it's something
else, we can only guess that maybe(?) it's Gmail.

We do know that it tends to cause problems mostly when email is
redirected (mailing list software has had to grow ugly hacks to try and
convince Gmail (and its siblings like Hotmail) to keep accepting their
messages).
