When I send message to this mailing list, I keep getting the following
bounce message from namezero.com's mail server. Apparently, someone who's
e-mail address is a namezero domain that forwards to a Yahoo account is
causing these bounce messages.

Shouldn't the bounce have gone to qmail-return*@list.cr.yp.to instead of
me? Is namezero's mail server sending bounces to the From address instead
of the envelope sender?

Well, there's over 10,000 e-mail addresses that would have to be
forwarded. Wouldn't I have to create a .qmail-<name> file for everyone in
the MySQL database (would there be a filesystem efficiency issue when I
have 10,000 files in the directory?), and also keep these files
synchronized with inserts, updates and deletes done to the MySQL database?

I figure that it's cleaner, programming-wise, to just lookup the MySQL
database at the time a message is received rather than having to worry
about synchronization. But this lookup script has increased the load
average of the server above 10.
