Hi,
We have SME server 7.6 which is installed with 1 NIC. The email is working fine for the local network users so we decided to open ports on the Draytek 2830n router so that we could access the emails using smartphones.
We can connect to the webmail OK but cannot configure the smart phones or mail clients outside the network.
I have checked and the ports are open correctly on the router, I have tried port 25, 143 443 and 110 but nothing. I am also unable to telnet into the mailserver.
If I connect the VPN first then all works fine.
What am I missing, I didnt think I needed to open any ports on the server as all local mail is working fine.
TIA Mark
