My understanding of the SMTP resource fields "From" and "To" are that they
work off the SMTP "Mail From:" and "Rcpt to:" fields. CC and BCC are part
of the DATA section of an SMTP message. If you want to send the message to
someone your e-mail client will specify them on an "Rcpt to:" line and would
activate this rule.
Therefore BCC and CC shouldn't be a problem.
However, My $.02. We used to use Pegasus Mail here. Pegasus (and probably
others) allow you to specify just the username on the To:, CC: or BCC:
lines. We had quite a difficulty recognizing that. A user would try to
send an e-mail to user1 instead of [EMAIL PROTECTED] and before our SMTP
Security Server implementation it would work. Quite confusing and difficult
for our users, so be careful about it.
Good Luck,

But wouldn't that also filter out legitimate mail where you've been CC: or
BCC:ed? I mean, with that kind of a rule in place, I wouldn't have seen
your message (or nearly everything on this mailing list) at all.
Your suggestion is certainly effective; it just works too well for my taste.
