I have deleted the whole directory in /var/qmail/spamdyke/graylist of this
domain. Now i can see how it works.

I understand the way your graylisting works. You don¹t graylist by server
because if a email comes from a big freemailer it is possible that the
second sending comes from a different server. Am i right?

As the domain was used by a spammer as mail from domain, there are many
emails whit the same mail to, so i get many bounces to the same recipient
from many different servers. All of them with the sender (unknown).

I see there is no way to stop these spam bounces. As i use smtproutes
spamdyke could not check if the recipient is ok. My Qmail sends all of these
bounces to our customer. No problem at all, because our customer bounces all
email which have no valid recipient. It¹s just a lot of work for spamdyke
and Qmail. ;-) (5000 email/hour == 1% CPU load).

Thanks for your work on spamdyke and thanks for your support.

Betreff: Re: [spamdyke-users] Greylisting Problem

If you're receiving a lot of these bounce messages from other servers,
is it possible this particular server has sent a message in the past? If
so, the graylisting has already taken place and future messages are
allowed without delay.

If not, I'd look for errors in the logs and check the amount of free
blocks/inodes on your server's drive. Have you looked through the
graylist folder structure to see if an entry for this sender/recipient
combo already exists? If you delete the entry, is the next bounce
message graylisted?
