The main reason we reverted back to postgrey was because OpenBSD spamd cannot add an SMTP header to mails detailing how long the mail was delayed for. postgrey, since it's a postfix policy service, adds an X-Greylist header to mails allowing users to see just how long the greylisting delay was. This feature has come in handy for tracking down greylisting problems. An example header: X-Greylist: delayed 360 seconds by postgrey-1.30 at mx01.sc1.parodius.com; Mon, 04 Feb 2008 21:02:35 PST Here's an example of one which I should probably track down in our SMTP logs to see if the delay was caused by something other than redelivery time on the remote SMTP server: X-Greylist: delayed 16000 seconds by postgrey-1.30 at mx01.sc1.parodius.com; Mon, 07 Jan 2008 10:33:09 PST I would love to try OpenBSD spamd again, but it's not a policy service service like postgrey is -- OpenBSD spamd has absolutely no way of inserting any data into delivered mail, because it's implemented with pf(4) and is not a policy service. It's quite possible to make a piece of software that would act as a policy service for postfix which could get details of greylisted mails and when they were actually delivered by OpenBSD spamd. Just thinking about it makes me consider writing it. :-) Would be quite useful... -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
