I can't say I've seen xmail behave as you're seeing. I was getting lots of bogus bounces incoming from systems that have attempted to send from forged valid addresses @lordynet.org to invalid addresses and these have correctly been rejected by xmail (EAVAIL) but the badly configured remote system then returns a bounce email to the rejection back out to the forged sender, also including the original spam content. These were more than a little annoying due to effort in working out what was happening. It seems to have been fixed now.
