Anyone else having issues with sending e-mails this evening?

I have not changed any settings and the last e-mail I sent was last Saturday but tonight is different.

I have settings correct... pop.cox.net, smtp.cox.net, 25 - unsecured, etc....  I even turned off my firewall for a few minutes and I receive the same error message.

Task 'pop.cox.net - Sending' reported error (0x80042109) : 'Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'
