[IMail Forum] Greetings!

[Doug Traylor]

Greetings to all list members.  I have just subbed and am looking forward to catching up on the tips and tricks of Imail.  We have been using Imail 6.0x with ~150 users for a few years with no problems.  We decided to upgrade to 8.0x after a Microsoft patch affected the Imail Admin with the added benefit of the spam handling.  We are running Imail on a Dell server with two 700 mhz Zeon processors and 512 MB ram.  The server also provides our VPN access for roughly 40 remote sites and is running an email antivirus scanner that checks the email prior to it being redirected to Imail(Interscan from TrendMicro).  Average CPU usage is minimal, somewhere around 3%, with occasional spikes to ~20%.    The system works well, but having Interscan in front of Imail hides the connection IP address from Imail DNS Blacklist antispam checker.  Since Imail doesn't analyze the headers, it sees only the connection from Interscan which is of course, us.  I have implemented the phrase scanner and domain scanner with the seed files from Ipswitch and that, with the statistical content filter, seems to be catching the majority of spam, but I want more.  There are a few options available to us that require throwing money at it but I was wondering if there was anything I can do with what I've got to improve things?    Thanks loads, Doug Traylor MIS Department Harbison Fischer MFG Crowley, Texas
