After reading the following topic: https://community.sophos.com/products/unified-threat-management/astaroorg/f/56/t/48548
which didn't see a proper closing I'm still confused when the Upstream Host List has to be used.
My MX setup is like this:
MX preference = 10, mail exchanger = myhost.xs4all.nl (= astaro box)
MX preference = 20, mail exchanger = relay.transip.nl (= fallback mx at domain hoster)
The domain hoster doesn't use greylisting. (what often happens is that the sending host is greylisted, after which the mail is immediately sent to my fallback mx which in turn delivers it to my box)
Questions:
- Should I enter the relay.transip.nl host in my (Astaro V8) Upstream Host List,yes or no?
- And if so, should I exclude the relay.transip.nl host from any other checks in order for the antispam measures to work properly..?
