Scanning multiple domains

Question

Hello

I was hoping to be able to acheive the following with PM on UNix :

Scan multiple email domains. Each domain is hosted on external SMTP servers. We want to be able to scan our customer's emails and then forward them to their email servers.

So far I have added relay_domains to main.cf and also setup the mapping in transport. All this using the postfix supplied by Puremessage.

Is this the right way to do it or have I missed something?

Thanks

Hi There,

That's exactly the right way to allow Postfix to receive/process e-mails for these other domains.

In terms of how they will be scanned by PureMessage, this will depend on the policy you have set up. By default, all e-mails will be scanned the same way, unless the e-mail arrived from an 'Internal Host' indicating that it is an outbound message. Outbound messages have a different scanning policy by default (for example they are not scanned for spam).

If you are going to be sending outbound messages from these domains as well, you will need to add their MTA I.P.s to the mynetworks setting in main.cf (this will allow them relay access to send to external addresses). You might also want to add their MTAs to /opt/pmx/etc/internal-hosts so the scanning policy is processed correctly (as described above).

Hope this helps,

Tom.
