Here is the copy & paste of the error message I get. I've redacted the
email address and account name for privacy reasons. I hope they are not
required for troubleshooting the issue of not being able to send emails over
the last few days. Thank you again, Jerry
The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.
The rejected e-mail address was '****.com'. Subject 'Re: mail test',
Account: *********, Server: 'mail.warwick.net', Protocol: SMTP, Server
Response: '553 sorry, that domain isn't in my list of allowed rcpthosts
(#5.7.1)', Port: 25, Secure(SSL): No, Server Error: 553, Error Number:
0x800CCC79
There is not one specific cause for failure to send, so it doesn't
make sense to ask for a "solution to this".
If you would like some custom help, right-click on your error
message, copy, then paste it into a reply here.
We can't do much troubleshooting without the complete error message.

As of just a few days ago, I also lost the ability to send emails. The
error message is the same as the two or three other users who have
recently
reported this problem. I changed my SMTP port from 25 to 587, but still
being blocked. I also disabled the outgoing email scanner. Have we come
up
with the solution to this? Thank you, Jerry
