Steve,
If they always use the same IP, then use the SMTP Security, Control Access
button and (read carefully, as people have been known to set it to the
reverse of what is desired!) enter the IP they use. This will cause IMail to
refuse connections from that IP on the SMTP service.
Contact the owner of the IP or upstream provider and they should be able to
help you, too.

Hello ladies and gents can someone tell me what the proper thing to do is
when someone try's to dos your server by connecting to it over & over
continuously. While they never were able to deliver any mail they were
blocked by the MAPS system. So they got Accepting SMTP connection from
[203.197.32.158]
Wed 2000-11-22 20:07:38: [632:9428] 220 ESMTP ready
Wed 2000-11-22 20:07:39: [632:9428] EHLO www.ilfsdp.com

I included their IP and hostname just in case anyone else might want to put
them in their personal IP blocking cache as well.
Who best to go to about it. I thought about the FBI but then again since
they never could bring the server down im not sure they would do anything
about it .
