But the OP specifically mentioned "all people writing mail servers" and other than the first one above have little to do with an MTA. BTW, searching Google yields http://projects.puremagic.com/greylisting/ which is the functionality I assumed the OP was asking about. >>Here's the one implemented by postgrey for postfix (simplified): > > It's neat that you can inject stuff about your IMGate into the thread, > but that is off-topic. Postfix isn't the only MTA that has the delay at first contact functionality (see, I didn't call it greylisting :-) several other MTAs have that capability too. In fact its even available as a stand alone function http://www.openbsd.org/cgi-bin/man.cgi?query=spamd#GREYLISTING -- [EMAIL PROTECTED] "The avalanche has already started, it is too Rod Dorman late for the pebbles to vote." � Ambassador Kosh To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
