I'm ignoring your email, if its an important topic you'll send beer to grab my attention first. -----Original Message----- From: Simon Lyall [mailto:simon(a)darkmere.gen.nz] Sent: Tuesday, 14 February 2006 1:41 p.m. To: nznog Subject: Re: [nznog] SMTP Greylisting On Tue, 14 Feb 2006, Craig Whitmore wrote:

Personally I find greylisting a pain. I am subscribed to a couple of lists that use it and it's annoying when my reply to the list takes half an hour to get through instead on 2 minutes. One important thing to watch for is that for larger sites the server that first tries to send your email might not be the one that tries to resend it later. Greylisting sites will thus block the email for a while until the sending site gets lucky and uses the same machine twice in a row. Generating random error messages to sending sites is just asking for trouble IMHO. You really can't determine exactly they will act and how long they will take to retry to send the message. Any delay is 100% your fault although most people using greylisting seem keen to push the blame to the sending site. It's the equivalent of ignoring someone when they first email/call you and saying "If it's important they'll ring back" . Not very polite and possibly not providing the best service to customers. -- Simon J.
