[qmailtoaster] greylisting warning
Hey Guys, I ran into a problem while testing a greylisting patch from Bill Shupp's site. Many of the new antispam appliances and certain firewalals are used as a smart host, so it looks as follows: Exchange - antispam appliance - QmailToaster Many of the antispam appliances are having issues with temporary 4xx errors, they will not retry later as per the standard. I've run into this a few times, and it's always tough to diagnose. Just thought I'd put out a notice that if you use greylisting, you may lose valid mail because of this.

Buyer Beware Erik I'm becoming less and less excited about greylisting as time goes by. Still haven't tried it myself. My present toaster configuration is doing pretty well without it. -- -Eric 'shubes' - QmailToaster hosted by: VR Hosted http://www.vr.org - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
