I have one client that has about a dozen email users, they complain their email on their devices says can not connect to server.
I troubleshoot and find they have ended up on the IP list in the firewall
I whitelist them and their email goes through fine, BUT within hours or days, the issue has recurred.
ALL devices seem to be configured correctly and email works fine if I drop the firewall...
What could be causing this from their end? (I have MANY clients with way more email accounts and NO issues...EVER)
As they move around and use many devices, it could be just one device causing this issue, but what could the server be seeing that would cause it to add the IP?
