Re: qmail forward to postfix on the same machine ?
Hello again Would it be bi-directionnal ? I mean does incoming email are routed to the internal qmail server , I need this because qmail deliver emails to few users on this machine in a special way .

There is one caveat, though: qmail-send will disassemble multi-recipient posts, i. e. you will get one Postfix message and queue ID per recipient - and Postfix has some VERP support (Mailman, for instance, uses it.) If you can somehow manage to inject outgoing mail directly into Postfix, so that you can bypass qmail-send, that may help quite a bit. If your software talks QMQP for injection into qmail for sending outbound mail, you can make Postfix provide a QMQPd.

The following construction has worked for years at securityfocus.com: SMTP protocol - qmail - ezmlm - QMQPD protocol - Postfix This construction was chosen because qmail was falling behind with email deliveries.

Thank you [please do not top post] The simple example I posted above should not change the path of incoming SMTP mail. Incoming SMTP mail should still be handled by qmail, and postfix should only listen on 127.0.0.1:2525. There are tools in your OS to define which MTA will respond to the mail or sendmail local commands, such as system reports sent by cron, etc. -- Noel Jones

Re: qmail forward to postfix on the same machine ?
Qmail ( which i know very few ) seem a bit autistic when talking to non FQDN distants servers or with MX misconfigured. I'm not surprised, it's pretty picky about non-standard behavior. my idea is to add a postfix instance on this machine which will send emails to the Internet. In my plan Qmail will inject all outgoing SMTP traffic into Postfix instance that will send it outside . That's pretty straightforward. One way is to set up postfix listening on a local port, say 2525, then in /var/qmail/control/smtproutes put :127.0.0.1:2525 to tell it to send all mail via SMTP to the postfix listener.
