I have used Dyndns for 4 years on port 2525 and never had a message
bounce due to problems on my end.

I can vouch for 'em too. I love dyndns.

All in favor say "ey"

"EY"!

thanks for your response. however, authenticating did not solve the
problem. bellsouth's mail servers use anonymous access for users of
their service. also, when i switched it back to anonymous, i can no
longer send email to users at @bellsouth.net

set to forward all mail through mail.bellsouth.net. my problem is
that they can only send to email addresses at bellsouth i.e.
@bellsouth.net. all other emails bounce back almost immediately
with this error:

You need to authenticate to the SMTP server - find the SBS SMTP
connector in
Exchange system manager, go to its properties/advanced/outbound
security and
enter the valid username/pw there.



i have a POP connector set to fetch their current email from their
bellsouth.net email,

Not related....

and it comes through fine. btw, those are the
email addresses i tested sending to. i know that they are not
going to be able to receive emails on this server until they
upgrade to business DSL (bellsouth blocks port 25), but they
should still be able to send, right? i could be wrong, but if
they can send to x...@xxxxxxxxxxxxx, shouldn't they be able to
send to x...@xxxxxxxxx?

Not unless you're allowed to relay through it - and you will
probably have
to authenticate to the SMTP server to do that.



thanks for your help
