Selective greylisting
2007-10-19 by Arjun Datta
Hi,
My
Setup:
2.6.20-1.2962.fc6
milter-greylist-3.0-1
milter-greylist-debuginfo-3.0-1
sendmail-8.13.8-2
milter-greylist-debuginfo-3.0-1
sendmail-8.13.8-2
I have noticed that
my milter-greylist seems to on occasion selectively greylist
senders.
For
example:
My domain is xyz.com
and has 2 users user1 and user2.
If sender@... sends an email addressed
to both user1@... and user2@xyz.com and both tuples are not
whitelisted, the first time milter-greylist will tell the sending server to
try again later as greylisting is in progress.
The second time the
sending server tries to send the email, milter-greylist will let the email
through to user1 and autowhitelist the tuple but will greylist user2
again.
I've checked that
the sending server has the same IP on all three
occasions.
Regards,
