Hi All:
What's the easiest way to block a maildomain from using our smtp
server? We have some customers that have infected PC's that are
sending out spam. We want to force them to use their ISP's outgoing
mailserver but still allow them to connect to pickup mail from their
inbox.
We have been blocking their IP's in /home/vpopmail/etc/tcp.smtp but
since the IP's keep changing this is becoming tedious.
Require authorization for those accounts, and then deny SMTP auth for
those users.
vmoduser -rs u...@domain
Regards,
Bill
