Surely someone has to be having this issue..
When I am connected to wifi at the office my DNS server gives me an internal DMZ IP for my email server...when I leave and connect to wifi somewhere else or connect to cellular data I get a connection error. Regular internet works fine.
I believe this is because the OS is not flushing the DNS cache when the connection changes state.
If I reboot everything is fine.
