Error 0x800ccc78

I've suddenly started receiving an error that won't allow me to send email
from Outlook 2003. I have a new computer (less than a month old) which
started this behaviour. I checked the old machine and it does the same
thing. I've checked twice with my ISP and they insist it is an Outlook
problem, not on their end. Here is the full text of the error.


Task 'mail.mchsi.com - Sending' reported error (0x800CCC78) : 'Unable to
send the message. Please verify the e-mail address in your account
properties. The server responded: 550 173.26.75.75 blocked by
ldap:eek:u=rbl,dc=mso,dc=att,dc=net -> 550 Temporarily blocked due to excessive
message traffic.'

In this case, the problem is with the server, not MS Outlook. You have
exceeded the number of messages that they permit to be sent. I have no idea
what the Mediacom limit is. Email rate limits are often something like "X
Recipients per time period", as compared with "X Email messages per time
period". So, if the limit is 100 per day, you may send either 1 email to 100
recipients, or 100 emails to 1 recipient each; or some combination thereof.

Thank you for your response. My ISP eventually owned up to the blockage
being on their side. They also have now said there is no limit on email.
What ever they did, it's working again now and they acknowledged it was their
issue.
