Re: remove from pending process

Ok, now I got how it works.

TMDA does not delete the pending message from queue when the message is
released. It deleted the message when it passes thru tmda-inject and has
those headers.

X-TMDA-Confirm-Done: 1173637813.10903.391df5
X-TMDA-Released: Sun, 11 Mar 2007 14:30:28 -0400

If it has those headers tmda deletes it from pending directory.

My problem is that when the message is released it is passed to postfix #1,
this postfix does not have tmda installed and because of that is does not
delete the messages from pending.

To correct this behavior to my needs I changed Pending.py to delete the
message when it is released. Now everything is working fine.

I´ll try to write a howto about it, this week and post on the website. I
belive that many people want to protect their exchange servers with an fine
opensource mailserver like postfix and a *free* challenge-response software
like TMDA.

Stephen, thank you for your answer. It let me to the solution.
