[IMail Forum] Spoof Problem

[Glenn Bullion]

There is an IP address out there that is constantly sending us spoof mail, and the volume has picked up.  They have a few aliases apparently, as multiples suffixes show up in the log (.com; .net; .org).  I added this IP address under the Control Access button in SMTP Security, so I believe they have been effectively blocked out.  Are there any other steps to take?  Is there a website to report this IP address?
