[SA-exim] greylistnullfrom problems.

[Michael Heiming]

Hi!

Strange problem with greylistnullfrom, which is set to (local.cf):

[..];'greylistnullfrom' => '0';[..]

Running:

Greylisting.pm,v 1.4 2006/01/11 17:17:28 marcmerlin Exp $

exim/exim-sa version (rpm):

exim-sa-4.43-1.RHEL4.5
exim-4.43-1.RHEL4.5

The problem it does actually greylist "F=<>" Null sender, despite it 
shouldn't from how I understood the configuration. Which might not be 
that bad with the recent raise of ratware, though it looks like it 
doesn't get whitelisted even if the remote MTA is resending in time. 
Though >99,99% of all mails with the null sender pass just fine due to 
none or very low SA score.

Running with "Debug: 9" in sa-exim.conf didn't revealed any clue why 
null sender are being greylisted.


Thx for any help on the matter


Michael
