Which servers are forwarding mail?

Post by mikrub »

Hi,

I am setting up a rule with a check_client_access map on my server for accepting email just if forwarded by Rollernet servers.
With regard to this topic http://forums.rollernet.us/viewtopic.php?t=184, from my server's logs it seems that email are actually arriving from

cache0.rollernet.us
cache1.rollernet.us
cache2.rollernet.us

Are these ALL the possible servers forwarding mail? Any other should I add?
Thanks guys

That's correct; anything that's moved out of the normal path by the Mail Forwarding feature is actually handed off to a separate pool of servers. We do this so that forwards always obey MX records from DNS and can't be tainted by what's configured in the account control center.

The pool currently consists of those three servers: cache0, cache1, and cache2. If you want to restrict by IP range, we've historically been numbering them out of 208.11.75.216/29 and 216.90.171.32/29, but as we add more servers and stop using our old IP ranges, the entire cache pool will use 208.79.240.32/27.

We'll also add this information to the resource access page.
