Stan Hoeppner put forth on 1/22/2010 1:28 AM: I've wondered for a couple of months why my rbl check is being skipped. I've not seen a spamhaus entry in my logs since Sept 25 '09.

Change behavior of return code
Hi, I'd like postfix to treat EX_CANTCREAT (73) as "temporary failure". I use this command to deliver my mails: mailbox_command = /usr/bin/formail -D 8192 ~/.msgid.cache -s /usr/libexec/dovecot/deliver The problem is that if the filesystem containing home directories is not mounted, formail returns an EX_... 22 Jan 2010 05:06
Exclude recipients from pre-queue spamass-milter checks?
We are experimenting with spamass-milter to check mails and reject them if a configured spamassassin score is reached. That part works, but the milter is (of course) applied to all mails after our smtpd_recipient_restrictions lookups return OK for the recipient, i.e. also postmaster@<various domains> for whom w... 20 Jan 2010 16:18

suppress NDRs from spoofed sender
My mail server has been getting a fair amount of spam hits that have been rejected but the sender address is spoofed with the recipient's address. This generates an NDR to the recipient with the spam. I would like to suppress NDRs of this kind but not legitimate NDRs. Regards, David Koski david(a)kosmosislan... 20 Feb 2010 14:39
The method behind the madness
I realize the developers and senior ops may be a bit irritated by some of my recent queries. I plead ignorance - and a desire to improve. I currently utilize ASSP as my primary filter. In the past, I have heard that there is nothing ASSP does that cannot be done utilizing alternative tools - in many cases bu... 19 Jan 2010 21:27
Postfix sender reputation support in snapshot 20100117
postfix-2.7-20100117 changes the meaning of content filters of the form "transport:" (note: no next-hop destination) so that this form can be used to implement sender reputation schemes. Typically, mail is split into classes, and all mail in class X is sent out from an SMTP client IP address that is reserved for c... 18 Jan 2010 10:52
