Hello,

I use BellSouth as an ISP. I had my mail working properly
when I installed my Exchange 2000 Server. Since then,
BellSouth has begun blocking port 25. Now, I cannot send
or receive e-mail through my Exchange server. Does anyone
know any steps I can take to fix this or know of any
articles that explain why I can no longer send/receive e-
mail from my domain.

Thank you,

ISPs block personal (non-business) accounts in an effort to block
SPAM. It is a resonable thing to do, under the circumstances,
especially since most personal accounts don't run email software. Some
ISPs (I think Adephlia is one) that specifically forbid running
servers (some forbid FTP, some SMTP and some both) again same basic
idea.

If you have a presonal account, I doubt you can get them to
change--they'll just try to sell you a business account. The
assumption is that business users generate higher traffic and hence
cost more. <g>

You could (should) ask your ISP if they can unblock you, but I don't
think you will have much success--your IP is probably dynamic, or
NATed, and there is no way to handle that except to assign a fixed IP.
NATed addresses are free, assigned fixed IPs on the Internet are
rarely free or easy to obtain.

Hi,

I would recommend you to talk to your ISP, they might have a solution for
you.

Other solutions involves something like dyndns.org offers:

I'll answer the second part first. There aren't any articles to
explain this, because it's too simple for an article. SMTP uses port
25. Your ISP blocks port 25. Therefore, you can't send/receive
email. You *can* configure SMTP to use other ports, but then the
sending SMTP has to know which port to send to, and you have no way of
telling them that. You could send mail out but never receive it.

Now the first question. There are three ways around this:

1) Switch to an ISP that doesn't block port 25.

2) Get BellSouth to stop blocking port 25 for you.

3) Switch to using an outside mail server.
