I feel compelled to point out, that blocking specific IP addresses from sending mail may require MORE than just entering them in the IMail access list.
Ideally, your Imail server will have a backup MX - which is GOOD, but allows mail from blocked IPs to sneak in through the back-door. If you block a.b.c.d within Imail, then their mail server will use your backup MX to deliver the mail. Your backup MX will then SUCCESSFULLY route the message to your Imail mailboxes - because it now connecting from its own IP address. So - if you are trying to block IP ranges from sending email, remember to duplicate those access lists to your backup MX(s)!
