Hi Dwayne,
This was done years ago to close spam relays.
To prevent junkmailers from appearing as legitimate CCN emailers and
abusing our mail system, the SMTP entry of your system _must_ be set to
your ISP address and not to: chebucto.ns.ca. Mail sent to offsite
addresses through the SMTP server will be bounced or denied. Send your
replies from your ISP address from now on.
The reason for this action is that spammers (junk-mailers) have, in
the past, used CCN's mail server to send their junk email by directly
connecting to the SMTP server. This has led to two problems:
1. CCN's response time for legitimate users was slowed down or, in
a few cases, cut off completely due to the overload on the
system. CCN has crashed completely in more than one instance
due to the overload.
2. Other Internet providers who were upset at getting junk email
relayed through CCN's servers were threatening to cut CCN off
completely from sending any email to their servers.
Closing CCN's SMTP server from outside access for relaying was a
necessity. Unfortunately, there is no way to do it selectively as
there is no way for the SMTP protocol to distinguish between a
legitimate user and a spammer.
