In order to stop spam, I want to refuse all connections to the smtp port
for certain machines and domains. As I understand it, I can have sendmail
bounce the mail, or just use tcp wrappers to deny connections from the
machine/domain.

Is one way considered better? I think sendmail would be better because
they would probably get a bounce message, rather than a connection
refused. Banning with TCP wrappers would prolly be easier, tho.

Any thoughts?

namaste,
Mark

BTW - I want to ban them from sending mail to any of the users, that's why
I'm not using procmail.
