Outgoing Mail Error

[Guest]

Just as of today, when I am trying to send an email, any email, out through
Outlook, I will receive a mail delievery error message - "This message can
not be sent because one of the receipients was rejected by the server. Server
response : '550 relaying mail to xxxxx.com is not allowed'. (Account
'xxxxxx', SMTP Server 'xxxxxxxxxxx', Error Number: 0x800ccc79).

I have checked to ensure all my passwords are correct. I work off of a
stand-alone with a DSL connection. Any help would be appreciated!

Could be your outgoing server is down or you have an incorrect setting--such
as-- Use SPA or Secure Server--neither of these should be selected. Ask your
ISP. This can also occur if you are trying to send email from another acct
that is not your ISP's acct.--such as your work mail from your home computer.

You need to authenticate to your outgoing server. Set this up by clicking
"More Settings..." on your account dialog and going to the "Outgoing server"
tab.
