GMail will not Send

Recently setup eM on my machine.  I can receive emails, it syncs good, calandar and chat work perfectly.  However, I am not able to send out any emails.

Log:

Any help would be greatly appreciated.

Thanks

Hello Brice,
can you please add eM Client to exceptions in your security software (antivirus, firewall)?
It could be blocking the outgoing messages.

Otherwise I might need to see the SMTP setting from the Menu>Tools>Accounts window.

I’m having the same problem - Gmails just sit in Outbox and don’t send; incoming messages have no problems, and folder operations seem to work. My log provides some different information (below). Would be grateful for some assistance. 
Thanks
