Default Debian Postfix UNSOLICITED BULK EMAIL, apparently from you

I followed the How-To for Debian Etch/Postfix/Virtual and after a week of successful testing started getting the following error:

Code:
From: Content-filter at mail1.server.com
 [postmaster@mail1.server.com]
Sent: Sunday, June 24, 2007 1:01 PM To: name@server.com 
Subject: Considered UNSOLICITED BULK EMAIL, apparently from you

A message from <name@server.com> to: -> somename@yahoo.com was considered unsolicited bulk e-mail (UBE). Our internal reference code for your message is 15973-07/ipyPfF8DMCzg The message carried your return address, so it was either a genuine mail from you, or a sender address was faked and your e-mail address abused by third party, in which case we apologize for undesired notification. We do try to minimize backscatter for more prominent cases of UBE and for infected mail, but for less obvious cases of UBE some balance between losing genuine mail and sending undesired backscatter is sought, and there can be some collateral damage on both sides. 

First upstream SMTP client IP address: [xx.xx.152.161] xxxxx.res.rr.com According to a 'Received:' trace, the message originated at: [xx.xx.152.161], design1 (xxxx.res.rr.com [xx.xx.152.161]) Return-Path: <name@server.com> Message-ID: <6A6ED8E39D444ECCB967390EFA5A9DE2@design1> Subject: RE: Question about shipping for xxxxxxx

 Delivery of the email was stopped!
this is sent from my wife's Outlook account, although I also get similar messages from Logwatch and other local processes where I can guarantee I am the sender. I have run the test at abuse.net for relaying and it passed. What process is blocking this? Is it postfix or something amavisd is calling up?

BTW, I'm a supporter with a subscription, but the forum doesn't list me as one, how do I change that?

Thanks,

Is your server located in a adatacenter or do you host it on a dynamic IP address?

I am at a datacenter as a colo box running a mailserver on dom2 on a Debian Etch xen SMP Xeon. I just added a valid reverse DNS entry, and the IP isn't blacklisted anywhere.

Thanks,

Do you manage your IP address yourself, or is it managed by your ISP? Usually the ISP does that, and then he'd have to create the reverse record.

My ISP created the reverse DNS record, well, I sent a ticket in to them to have it done.

I just editted /etc/amavis/conf.d/20-debian_defaults and added my domain to the read hash list:

# read_hash("/var/amavis/sender_scores_sitewide"),

{ # a hash-type lookup table (associative array)
'nobody@cert.org' => -3.0,
'cert-advisory@us-cert.gov' => -3.0,
....
'.server.com' => -8.0,

and it fixed it, but I doubt I really fixed it, I can't do this for all the virtual hosts , yet I don't want to raise the detection much above the standard 6.31, that's higher than I'm used to having it.

Thanks,
Cameron

Hi !
I have the same problem... No fresh idea to help me ?
I have not change my reverseDNS, seems not to be a good idea at all... ?!
I've haded my domain in /etc/amavis/conf.d/20-debian_defaults too...
I don't receive the logwatch emails, it's not practical.
Recently, on one of my two servers encounter the problem, the mail arrived, but that this day there...
Probably a ghooost
Falko, an idea ?
Thx,
Tisc
