I currently use greylisting for 1s because my postfix version predates postscreen :-( The good folk of #postfix on Freenode told me (IIRC) that postscreen should obviate the need for greylisting. We have to turn greylisting off for Telstra because they have a mail farm, and when postgrey says "try again later", they try from a different node in the farm and so get told "try again later" again. We also do some SPF, but that's pretty boring. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
