I've received hundreds at the address I use for newsgroups, and almost none
at my real address.

Ditto. This hotmail address which I have used for usenet posting (and
only that) receives at least 10 spam emails per day. Quite obviously
been trawled off the newsgroups; nobody is going to have hit on a
stupid username like davidlobsterpot601 by fluke or other spammer
techniques.

ISTR that it's apparently 'safe' to set your posted 'Reply-To:'
address as your real one; the spammers don't touch that, it's the
'From' address that they go for.
