Sendmail & MailScanner - can't connect from public addresses



Hello,

Finished setting up the latest MailScanner and Sendmail, however, although I
can connect to the mail server via telnet to port 25 from any machine on the
local subnet, it does not respond from any request from public IP addresses.
There is no firewall on this server. Nmap shows port 25 as open.  When I
open port forwarding from two other firewalls (from different ISP address
ranges) to the mail server and I get no response, when telnetting from the
public side to the smtp port.

It appears that either Sendmail or MailScanner is only accepting connections
from the local subnet.

Any ideas on how to fix this?

Many thanks in advance,

James
