Neither send or receive is working for my Yahoo or Gmail accounts. I have checked server setting, changed passwords and updated eM Client. Nothing works…period. Screen shots of my initial error msg, the next error msgs and the log file are attached. I would really appreciate some help or input as to how to fix this. 

If you click on the Open account settings button, check that you have one of the following port and security policy combinations:

Port 587 = Force usage of SSL/TLS
Port 25 = Use SSL/TLS if available
Port 465 = Use SSL/TLS on special port (legacy)

Port 993 = Use SSL/TLS on special port (legacy)
Port 143 = Use SSL/TLS if available

Port 995 = Use SSL/TLS on special port (legacy)
Port 110 = Use SSL/TLS if available

These are the correct combinations of port and security policy. The underlined ones are the best option for security if your server supports them. SMTP port 465 was reassigned and should no longer be used for SMTP, though many mail providers still recommend and use it.

If that does not help, disable your anti-virus application then try again.
