I want to setup a method by which only senders which are in a defined
list can send a message to a given recipient.
Something like the following (in pseudo code)
accept if sender and recipient
The idea being that each recipient will have their own whitelist, and
only messages from those
I'm trying to get postfix --smtp-- amavisd --lmtp-- dovecot all setup and
working nicely together. I've configured amavisd as a before_queue filter in
Postfix.
smtpd pass - - n - 20 smtpd
-o smtpd_proxy_filter=127.0.0.1:10024
-o
Thanks Viktor. I know I've read that before but I deal with about 3 different
MTAs in a given week, so I don't always remember all the in/outs of each. :)

I'm setting up LDAP to be used by Postfix, Dovecot, etc. for mail and other
stuff. I'm not understanding why postfix is failing to find the virtual domain
in question. I've got Dovecot setup and working against it, at least for
authentication at this point.

I'm not sure what I've done wrong, but aliases for virtual users is not
working. A postmap -q key map returns what it should, but when I send a
test message, the alias address is passed to the downstream system, instead of
the result of the lookup.

Before I go and write my own solution I thought I'd see if anyone knows of an
existing solution.
Now and again I'd like to put an IP on a local blacklist and have an expiration
time set as well. I'm using postscreen as well and ideally the blacklist will
get implemented via postscreen.
I don't think the problem will be with the marketing software, i.e. the
component generating the messages, that is the easy part. The harder part is
on the MTA to deliver those. Long ago I saw a request from a customer that
wanted to be able to send out 1M in an hour I believe it was. I

Why did you remove that last line above? I thought about doing a before queue
content filter, but that really kills user's ability to train dspam. :)
Thank you Noel for the clarification. I think I've figured out how I want this
all setup. :)

I can't figure out how to setup an additional content filter based on a

Is it possible for a policy server to get access to the message contents? At
least headers?
In reading http://www.postfix.org/SMTPD_POLICY_README.html it talks about after
client has sent data. However since the protocol is name=value then I suspect
the answer is no. Though i do see queue_id

Is it possible to write a header check (I'm thinking pcre is probably the way
to go) that would find a header, and then take action based on the value of
said header.
Sample header
X-spam-Confidence: 0.8505
In pseudo code I'd like something like

Hello Chad
Is it possible to put the use of a smtpd_milter into a restriction class? From
what I've read so far I'm suspect the answer is no. In which case I'll have to
put the functionality into the milter itself, MIMEDefang in my case. I'd
prefer to keep the restriction classes centralized if you
I am using postfix as a relay MTA, i.e. the MX points at it, it applies various
filters and then relays the mail to final systems.
Is it possible to configure postfix such that say some header checks are
applied to certain domains that relay mail and not apply those checks to other
domains?
