Sorry, but I have one other question. Are you still using obspamd on the
machines you set up when you wrote the above link? Your reasons on why or
why not would be greatly appreciated.
No, we're not. 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...
It would be very nice to have and useful information. Especially now
that I am impatiently watching my tables grow and waiting for emails
that I have seeded from many other sources, I am far from comfortable
with pfspamd but seeing that I have received almost no spam since I
started the test, is currently compensating. I would give postgray a
try but don't have a server running postfix right now and don't have a
lot of time and for now am going to set up pfspamd on all unless I
find some major issue.
Thanks again for all the useful information.
