You have to be careful, though. For several years on one of my lists I had a subscriber whose address was something like (I don't recall exactly) "nobody@not-a-real-address.somewhere.net", which was a perfectly valid address and at which he/she/it did receive mail and from which he/she/it would reply.
Agreed, care is needed in order to avoid false positives. ("nobody", by the way, is often aliased thus in stock sendmail installations on various 'nix boxes:
nobody: /dev/null
so while there's nothing wrong with it per se -- and it's not a special address per RFC 2142 -- I find myself wondering how many people have hardwired it into various anti-spam setups. ;-) )
I should probably mention that I'm not a fan of noreply@example.com and similar addresses, which seem to be often used these days for one-way mailing lists: I think *all* messages should be replyable. But I figure that, as a practical matter, as long as so many sites are using that convention, we might as well leverage it to our advantage.
