Can't send email through POP3 server

I'm working for a new company and am trying to set up my POP3 through
Windows mail. The incoming and outgoing servers are the same
(mail.companyname.com).I am able to receive email from this account.
When I try to send an email I get an error message:The connection to the
server has failed. Subject 'Test', Account: 'mail.brennco.com', Server:
'mail.brennco.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket
Error: 10060, Error Number: 0x800CCC0EMy company has tested my
incoming/outgoing email at their end and say it is fine. I called my
ISP (ATT) and the can not support anything other than ATT mail.Can
anyone assist - I really need to get this working!Thanks

Your ISP has a policy of not allowing you to use a non-ISP
mail server on port 25. This is a standard anti-spammer policy
as explained here: http://www.postcastserver.com/help/P..._Blocking.aspx

As a workaround, simply replace your current SMTP server with the
one supplied by your ISP. Your correspondents will not notice a difference.
If you need detailed help on how to implement this, let us know.
