Topic: How to use Postix as gateway?

Hi,

On my Postfix server, the main domain name is "partena.com". This server is used as outgoing server. Exchange may only send mail trugh Postfix.

For our email address, we use "partena.be".

So, we receive mail in this outgoing server.

In my log, I can see :

Aug 20 15:19:20 mailout postfix/smtpd[2637]: connect from unknown[213.6.65.73]

How can I permit Postfix to transfert all mail from partena.be to our Exhange?

Thanks for your help,

Christophe

Did you try to append partner.be to postfix 'relay_domains'?

No ...

I change my config and now, I can see

Aug 20 15:32:37 mailout postfix/smtpd[3435]: NOQUEUE: reject: RCPT from unknown[121.54.54.45]: 550 5.1.1 <liess.ferdinandnn@partena.be>: Recipient address rejected: User unknown in relay recipient table; from=<karie_shavonds@rus-tours.com> to=<liess.ferdinandnn@partena.be> proto=ESMTP helo=<sslxkvu>

Comment 'relay_recipient_maps' in postfix and try again.

Ok, now, I suppose greylisting is working:

Aug 20 15:38:00 mailout postfix/smtpd[3683]: NOQUEUE: reject: RCPT from unknown[78.250.160.171]: 450 4.7.1 <hstordeur@partena.be>: Recipient address rejected: Policy Rejection- Please try later.; from=<yyetege@nationalgeographic.com> to=<hstordeur@partena.be> proto=SMTP helo=<nationalgeographic.com>
