Dear List,
I have this in my main.cf
smtpd_end_of_data_restrictions =
check_policy_service inet:127.0.0.1:9998
This basically checks for mail size and allows/not allows a mail
based on contents of a file.
Is there a way to say, not to use this policy service, based on some
headers of a mail?
You can skip the policy based on envelope information by using a
check_*_access map before the policy check. You could also likely
do this inside the policy server itself.
You cannot skip it based on headers.

Thanks for your inputs. You are all experts, please share some
ideas with me to solve my problem. I have described the requirement
in detail as below.
Let me explain my current setup and my real requirement.
I have a front end for accessing and sending mail (say server A). All
mails sent from this (server A) are directed to another server (say
server B) for virus/spam check using Amavisd. If the mails are
addressed to any internet domain other than ours, mails get forwarded
to Server C, else mails are delivered locally.
A (Front End Mail) -> B (Virus/Spam scanner) -> C (for delivering to
Internet).
At server B (for local delivery of mails) we have a size limit of 30 MB.
At Server C (for delivery to Internet ) we have a size limit of 30 MB,
but using policyd feature of Postfix (at
smtpd_end_of_data_restrictions), by default we are restricting to 2 MB
and based on the contents of a data file (which is manually edited as
and when required) which contains Sender address and allowed size,
mails get get delivered to outside domains having higher size.
Now, I have been asked to develop another front end at same level as
Server A (say server D), to enable users to send mails of large size
to Internet users, such that, once a mail is composed and submitted
for approval, Based on the content, I can approve or disapprove.
Once approved, it should go through Server B and finally server C to
get delivered to outside domains.
My problem lies at Server C where I am running a policy for sending
outside mails. How does that mail be allowed without even looking at
policy (exception for policy).
Please provide guidance or any other alternative strategy to achieve
the requirement. But, it is must that, mail should go through the
virus scan.
Regards,
Anant.
