Vista - can't send or reply to email

My email has worked fine up until last night. I can't reply to or send any
emails. I get this error message:
An unknown error has occurred. Subject 'Re: ', Account: 'mail.charter.net',
Server: 'mail.charter.net', Protocol: SMTP, Server Response: '550 Message
identified as SPAM - Please visit http://www.charter.com/postmaster', Port:
25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC69
I called my provider and they say my settings are correct and it's not their
problem.
What happened??

This is a duplicate post, previously responded to under "can't send emails".

I too have had the same problem. I was able to receive and send e-mails fine
until the end of last week. Suddenly, I am able to receive e-mails but not
send or reply to any. I keep getting the following error message:

The connection to the server has failed. Subject 'Re: ', Account:
'thechef@xxxxxx', Server: 'smtp.everestkc.net', Protocol: SMTP, Port:
25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E

Any help would be greatly appreciated!

When you got that error, was your Internet connection coming through
Everestkc? Were you on a laptop away from home?
As a general rule, the owner of the SMTP server must be the same as
the one providing your Internet connection at that moment.

We can suggest some workarounds once we know your circumstances.

The laptop was being used at home; however, the internet connection was
through Comcast. Although these were not the same, it worked fine for almost
6 months and then suddenly no longer worked.

Any help?

Comcast has been in the process of phasing out all port 25 access.
Internet service providers are periodically tightening up their rules
and practices in order to slow down the spammers.

You will have to change the SMTP server name from smtp.everestkc.net
to smtp.comcast.net. Your correspondents won't notice anything different.
