Why does
% telnet exoco.net 25
from an external machine not work (it hangs), while it does function at the local?
What am I missing??
You're missing the fact that you appear to be connecting via Uni of Soton's resnet
network, who block tcp/25 outbound and recommend you use smtp.soton.ac.uk for sending mail
instead. Best to do testing from outwith a traffic-managed/filtered network.
