Can't send e-mail

[rosiet]

This is the error message I receive when trying to send email, this whole
thing started a few days ago.
The connection to the server has failed. Subject 'Emailing: max sheet',
Account: 'Empire', Server: 'outgoing.yahoo.verizon.net', Protocol: SMTP,
Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E
I did switch the port to 587 and was able to send 1 message and got this
error message after that:
Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Subject '', Account: 'Brian', Server:
'outgoing.yahoo.verizon.net', Protocol: SMTP, Port: 587, Secure(SSL): No,
Socket Error: 10053, Error Number: 0x800CCC0F

I'm wondering if this has anything to do with the last Windows update, it
seems that I'm not the only experiencing this problem, any help would be
appreciated

This is not the error number I received - mine is "server resp 550 5.1.0
with error
#0X800CCC78. pls respond. This has been switched to port 587 but still
cannot send
msg. Have just switched to Comcast.

Keep using port 587 instead of port 25.
The error "unexpectedly terminated" is usually caused by interference
from an antivirus program. Which antivirus are you running? Some of
them cause problems with Windows Mail over time. As a minimum,
email scanning in the antivirus should be turned off, although that may
not be sufficient to eliminate all bad effects. In a worst case scenario,
your antivirus may need to be uninstalled/reinstalled or replaced.

Email scanning in any antivirus should be disabled, for reasons

@Madjak: That's not the complete error message.
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..
