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,

Nagy, Attila:
This is implemented in Postfix 3.3, and will be in the stable
release in a month or so.

Feature: Milters can now send RET and ENVID arguments in
SMFIR_CHGFROM requests.

Nagy, Attila:
There are no plans to duplicate a full SMTP command parser in the
Postfix Milter client.
