It is Windows Vista running laptop with Windows Mail as default email client. It was working fine without any error so far but suddenly don’t know what went wrong, now when I click on Send, it gives me an error saying “Receive this error message: An unknown error has occurred. Protocol: SMTP, Port: 0, Secure(SSL): No, Error Number: 0x800C013E. What's odd is that it shows Port: 0. Outgoing mail should be Port: 25.”
Many people said it can be due to the Antivirus, hence I disabled email scanning in McAfee and disabled Firewall as well. That dint worked. Later I also did a system restore to a restore point made 3 weeks ago but that too wasn’t able to fix the problem.
