This probably means that they're not real accounts, spammers make up
random addresses to use as the sender address on their spam and
because mail.com (nee iname) have _so_ many domains it'll be fairly
likely that these random domains are registered to them.

Part of mail.com's business is having all these domains so their users
can pick their address from them.

I would strongly advise against doing that, especially the latter.
You could legitimately be accused of spamming _them_, since they
probably have nothing to do with 90% of the mail you get.
