postfig confiuration advice/info

First of all let me apologize if you have seen this "request/query" before. I originally posted this to Google Groups "mailing.postfix.users", but felt that that it was probably the wrong place to ask for advice. I then tried the Postfix oriented groups on my news service, only to realize that th

Action during SMTPD* checks

I have just finished reading a bunch of stuff on UCE and the "effects" of the various parameters associated with the smtpd_*_restrictions, and I am now somewhat confused as two of the authors I have been reading state that if a message receives an "OK" from any check then all further checks are aba

I am having a problem with some legitimate emails being rejected by header and/or body checks. Both the header and body checks are from Jeffrey Posluns' write up,without any mods.

450 response being delivered to a sender is a mistake - isn't it?

I was thinking about something I wrote here a couple of days ago. A 450 response from my server being delivered to the original sender is a mistake - isn't it? Everything I have read to date seems to indicate that 4xx codes are temporary conditions between SMTP endpoints. But as I am new to this I

postfix - amavisd - TLS

I run amavisd-new as part of my anti-spam setup. The configuration is pretty well out of the box. I use the split clean up, which if I remember correctly, is straight out of Patrick Koetter's setup guide. One of the things I have noticed is that when amavisd passes emails back into postfix it is us

Ubuntu, dynamicmaps?

I am thinking of switching to Ubuntu 8.10 LTS server, however when I look at the Postfix configuration it seems somewhat odd. I don't want to start a flame war, but I would like to hear what people think about things like "dynamicmaps" and other oddities of the Ubuntu Postfix configuration. TIA JL
