How to build a staging SMTP server RRS feed

  • Question

  • Does anyone have an insight on building a staging SMTP server as I'm planning to upgrade incoming Symantec BrightMail gateway to a newer version and I need to guarantee all incoming emails once the up-gradation is done.

  • 1. I assume you haven't got multiple Brightmail gateways, so can't use another.

    2. If your ISP/3rd party allows for the messages to be queued, then you should be OK, some users may receive a NDR for messaged delay.

    3. You can have any server that has SMTP.  What you can have is a Edge server in your DMZ and have another MX record pointing to this. Do you upgrade and then revert back.

    4. If you MX point directly to your brighmail then use the above advice or you can download many open source SMTP servers, but ensure you have AV/AS on them.

  • Build a new server, install Brightmail and then change and firewall rules/ NAT to point to the new server on port 25 so that mail goes to it instead.

  • Build the server as suggested above and then with your ISP register the MX to point to this new BrightMail with perhaps lower priority and then upon successful testing, do the cut over by increasing the priority please.

  • Not exactly understanding your requirement. Is the staging SMTP different server from the brightmail server? Do you mean you want to have this staging SMTP server queue the email during this upgrade? Do you mean you want to test the integration of an SMTP server with the upgraded Brightmail gateway?
