IMGate has reduced spam by at least 70% by my calculation on our ISP. I only had to make a few changes, specifically with the FQDN check for the helo/ehlo command since quite a few administrators seemingly are oblivious to the fact that they need a DNS entry corresponding to the network name of their mail server. That check alone caused twenty or thirty calls within days including a few teachers at schools trying to send e-mail to their home acct on our ISP. The schools around here are the worst with open relay and misconfigured mail servers.
Thanks again Len. And now for yet another question ;-). I've seen bits and pieces of information regarding AVGate as a supplement to IMGate (anti-virus), however, I haven't seen anything in detail. I simply need a template, or a point in the right direction to get the ball rolling. I'm still learning Unix, but know my way around enough that with a little grease I can make it work. I'm trying to figure out which AV solution to go with, and trying to find any AV/proxy (front-end, middle-man) or what not to use in conjuction with the AV soft. I'm assuming that the proxy would store/av_check/forward to Postfix. Any ideas? TIA BTW, a few IMGate stats: (typical estimate based on a 7-day log period with roughly 1200 users) Number of e-mail messages rejected by RBL per day: 2215 Number of e-mail messages rejected by invalid host per day: 129 Number of e-mail messages rejected by content per day: 11 Which brings to mind yet another question. Has anyone release a log analyzer for postfix. I love the one IPSwitch just released. -- -- Mind Information Systems LLC Technical Support Staff Jonathan Ingram Phone: (559)730-3600 Web: <http://www.mindinfo.com/tech_support/> -- -- Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
