Hi list,
Sorry again for being out-of-subject. Since I posted to this ML in last
resort (as GLD seems to be mainly related to Postfix), I thought that a
few readers using it but not having the clues to answer my question
(since I got no answer) could still be interested.
Other users, feel free to skip my prose and sorry for the pollution :)
AFAIK, it seems that the MXGREY feature of GLD is definitely broken, at
least for my (Debian stable) package. I personaly take it for granted
that it is also broken in the seed release. So you may want to switch to
other greylisting implementations. Most of them, unfortunately, are not
based on C, so they all seem to be a bit slower when it comes to speak
to the underlying DB. But... You may end up with a much smaller
greylisting DB (as my own tests show it so far).
I found sqlgrey to be very satisfying for me (but that is just my
personal experience) : A bit slower to update the DB, but with far less
rows being created. Of course you still have a lot of solutions to
choose from.
Hope this helps.

Sujet: postfix-gld: mxgrey not working?

Hi Postfix users,
I have to apology: This is not a Postfix problem. But since there seem
to be not mailing list for GLD, I was thinking that maybe some of you
may be using postfix-gld and have some clue for me.
BTW, if you know of a mailing list that would be more appropriate for
this question, let me know :)
I emailed GLD's author, but he didn't reply.
So... I'm using GLD for greylisting and just noticed today that MXGREY
doesn't seem to work at all with my setup.
My OS is 32bit Debian Squeeze, and I'm using GLD 1.7 (1.7-3 for Debian).
In /etc/gld.conf, I have set: MXGREY=10
In my greylist table, I have this record, among others:
IP sender recipient first last n
74.125.83.0 loic<snip>@<snip>.com l...@somedomain1.tld 1338411795
1338412124 11
Now I try to send an email from my company email to one of my other pvt
email address.
Here's what GLD says when started in debug mode:
_______________________________________________________________________
5190: New incoming connexion from localhost (127.0.0.1)
5190: Got the following valid data req=(smtpd_access_policy)
sender=(loic<snip>@<snip>.com) recipient=(l...@somedomain2.tld)
ip=(74.125.83.54)
5190: Starting the greylist algo
5190: lightgrey is on, let's remove the last octet of ip
5190: Query=(select first from greylist where ip='74.125.83.0' and
sender='loic<snip>@<snip>.com' and recipient='l...@somedomain2.tld')
result=0
5190: whitelist is on
5190: Query=(select count(mail) from whitelist where mail in
('loic<snip>@<snip>.com','@<snip>.com','74.125.83.54','74.125.83'))
result=0
5190: Query=(insert into greylist
values('74.125.83.0','loic<snip>@<snip>.com','l...@somedomain2.tld',1338412124,1338412124,1))
5190: Mxgrey Query=(select count(first) from greylist where
ip='74.125.83.0' and n>1) result=3 (minimum needed is 10)
5190: End of the greylist algo
5190: Decision is to greylist
___________________________________________________________________________
Well, I really don't get why email to this new address is greylisted,
since it is sent by 74.125.83.54, which should match 74.125.83.0
(because of lightgrey) for which n > 10.
Am I missing something?
Is my GLD binary broken?
Help will be warmly welcomed :)
Cheers
