Hey guys, wanted to see if I can can get any input on this here - had to Geoblock one of the countries for inbound/outbound traffic completely. Everything was fine until I found out that one of the employees started having issues with email delivery to the certain customer - "domain of sender address email@example.com does not resolve firstname.lastname@example.org". Turns out mail servers of this certain customer (as well as other server infrastructure) located in that Geoblocked zone. Tried to identify range of their public addresses and allow inbound/outbound dns and smtp applications from my mail server and on-prem dns servers (just in case).
Issue still exists. No problems/issues with incoming emails from email@example.com.
Will appreciate any help/suggestions.
