DNS2Go
Here are a few troubleshooting tips:
Can you establish a simple telnet session to the DNS2Go
mail server on port 25? From the DOS prompt type:
telnet mail.dns2go.com 25
If you are unable to connect through a telnet session,
verify that you have port 25 open on any local routers or firewalls. If you do
or are not running either of these, possibly your local ISP has begun blocking
outbound port 25 connections. Typically when they do this, they only allow
outbound port 25 connections to their email server.
You can attempt to telnet to mail.dns2go.com on port 110
and port 366. If you are able to connect to mail.dns2go.com on port 366, you can
use ATRN instead of ETRN. This uses an authenticated session and transfers the
email via SMTP on the same connection through port 366.
Either your local mail server would have to support
issueing the ATRN protocol of your could use the XATRN client from the following
