OT: Outgoing email fails in Windows Live Mail.

I have been using Windows Live Mail successfully with Windows 7 64bit until yesterday. As of last night, it won't send emails with any picture attached or imbedded, including the thumbnail icon from my virus protection software (this means all emails now fail since it automatically adds a sig file to every outgoing message). I can receive mail without a problem.

The error is:

Delete the photo email, create a new one, and try to send it again.

Server: 'smtp.eastlink.ca'
Windows Live Mail Error ID: 0x8CCC0003
Protocol: SMTP
Port: 25
Secure(SSL): No

Anyone know what's going on here?

Thanks! - D
