It isn't.

Or alternatively just report it using Spamcop (http://spamcop.net) or
some other reporting tool.  Life is just too short to do this by hand
every time you get spam.

On the Haskell mailing list we have a good compromise at the moment: the
mailing list software's auto-filtering catches most of the spam (not
allowing Bcc's to the list is a good one), and for any spam that gets
through I just add it to the list of disallowed addresses.  I asked
recently if we should move to allowing subscriber-only posting, and I
got a small number of responses, which were split roughly 50/50 so no
action was taken.
