<![CDATA[Postfix forwarder - relay all domains]]>Hi

We are using the forwarder to receive incoming emails from a trusted web server and relay them out to our trusted SMTP relay provider.
This works fine when we specify the  'To:' domain on the forwarder but for most of the emails we do not know the destination email domain.
Is it possible to set up a catch-all relay or use a wildcard?

Thanks

Have the [ our own Web server which generates very specific emails ] deliver the mails directly to your [ our trusted SMTP relay provider ] ?

Have you seen this post?

the web server is our own Web server which generates very specific emails requested by the recipient.
we are locking down the postfix forwarder so that only smtp traffic from this server on a non standard port is accepted. We then pass the email out to a global delivery partner with a very high reputation for delivery to the recipient. This partner will only accept emails from specific ip addresses hence the need to relay the Web server smtp traffic through our site.

How can this scenario be classed as an open mail proxy?

If you don't care that you are going to end up on about every blacklist in the world, just go ahead and set up open mail proxy!
