For receiving email there is nothing wrong.This is the error message:Code: Select allAn error occurred sending mail: http://answers.microsoft.com/en-us/windows/forum/windows_vista-networking/cannot-connect-to-smtp-server-in-windows-live-mail/4c29baf5-6be3-4b75-9b2c-8d24cbd1b53f The mail server sent an incorrect greeting: Cannot connect to SMTP server x.x.x.x (x.x.x.x:25), Connect error 10060First of all I thought the anti virus is the culprit.

If yes, how to solve it?(I try changing the SMTP server using the one from the ISP (using port 587), and the email then delivered)I believe the change above is temporarily solved the problem, that's why I asked on this forum to make sure.Please advise.Regards.
