I am unable to connect to port 25 using Telnet from localhost to my mail server but I’m able to connect to mail.vif.com and mail.hmailserver.com.
Am I missing something? Any help would be much appreciated.Karl

Is the localhost you refer to on the same subnet as the email machine? I use Hmail here and works great!
edit- damn spellcheck!
-
I'm using telnet from the same host (machine) where my mail server resides which is hmailserver. The IP ranges on hmailserver is set at, lower IP = 127.0.0.0 and upper IP = 127.0.0.0
I haven't changed any settings on hmailserver which is currently running fine using ISA 2006 firewall. -
The firewall would have no affect on the local machine. If you cant connect on a telnet client which resides on the same machine as Hmailserver then something is wrong on that machine.
On the Hmail administrator screen-
What are your settings for /settings/advanced/ipranges both /my computer and /internet?
Then under /TCP IP Ports- all types should have an IP of 0.0.0.0
Try mxtoolbox.com to test your incoming.

Here are my hmailserver settings and my results using mxtoolbox to connect to my mail server.
