Any plans to support setting ESMTP arguments with milter?

Hi,

I would like to add DSN parameters to e-mails with milter.

If I set these with smfi_chgfrom and smfi_addrcpt_par, I get:
warning: 3ybBmq5Wxvz43: cleanup_chg_from: ignoring ESMTP arguments
"ret=hdrs envid=qid"

I've read <a href="http://www.postfix.org/MILTER_README.html" title="http://www.postfix.org/MILTER_README.html">http://www.postfix.org/MILTER_README.html</a> and it mislead me,
because I thought only 2.6 has these limitations, but checking
cleanup_milter.c it seems 3.2 does the same.

Is this hard to do in the postfix mailflow and are there any plans to
remove this limitation from milter?

Thanks,

Deferring all mails after milter inspection

Hi,

What is the most effective way of giving back a 4XX temporary error for
all mails in postfix, but in a way that they are delivered to milter
programs (including message body, so smtpd_end_of_data_restrictions
doesn't work)?

So basically I would like to temporary fail all messages which get
through the milters with the smallest resource usage.

Thanks,

Postgresql as a dictionary coder backend?

Hello,

How to limit # of messages for one destination in the active queue?

Hello,

I have a somewhat busy mail relay running postfix 2.7, which has
problems with a slow destination.
The symptom: the incoming queue grows large, the active queue is always
at qmgr_message_active_limit and only (well, mostly) contains messages
for the slow domain.
What I have already tried:
- growing the active_limit, which of course could help only by setting
so high that it could suck in all messages in the incoming queue
- defining a different transport for the slow domain and setting
destination concurrency limits

I don't really get the point in this, but I guess I've just over

Sender based outgoing IP selection

Hello,

I have to route e-mails coming from different IP addresses to the world
(no single smarthost, the target can be anything) with different source IPs.

So a mail coming in on 1.1.1.1 should go out with the source address of
2.2.2.2 and another coming in on 3.3.3.3 should go out from 4.4.4.4.
Postfix listens on 1.1.1.1 and 3.3.3.3 and the machine has also the
addresses of 2.2.2.2 and 4.4.4.4 of course.

Am I right when I think this can only be done correctly with two postfix
instances?

Thanks,
