Re: I can receive email but cannot send it.

I am having a similar "can receive, but not send" problem with Outlook 2000.
I have been using an AOL Broadband connection as my ISP, but access a webmail
account (a 3rd party domain name/server) through Outlook 2000. This has been
working just fine for over a year...when all of sudden, about 10 days ago, I
stopped being able to SEND messages. Whenever I attempt to SEND a message
from Outlook I get the following error message:

"This message could not be sent because one of the recipients was rejected
by the server. Server Response: 553 your IP (xxx.xxx.xx.xxx) is on our block
list. (Account: 'mail.scottishsportsfutures.org.uk', SMTP server:
'mail.scottishsportsfutures.org.uk', error number: 0x800ccc79"

My 3rd party (web-hosting) server ASSURE me this has nothing to with them.
I believe them because I am able to send emails through my webmail account
and they can send emails to me when they enter my account details onto THEIR
computers. They are about 98% sure it has something to do with AOL putting
my domain name on some kind of spam-preventing block list. They told me to
call AOL and have it unblocked...but AOL also "ASSURE" me that they do not
put IP addresses or domain names on block lists.

The craziest part is -- that I have had ZERO problems using Outlook and AOL
over the past year...and all of a sudden, one day it just stopped sending
messages & starts giving me that same error message. I haven't done anything
to change my account properties/settings. My firewall allows full access to
Outlook.

I'm completely stumped and so very, VERY frustrated!

Can you offer any suggestions? ...pretty please????
