=Emails not sending

Hi,
I have set up my email settings exactly as they are set up in my email client, yet no emails are being sent out, not even the test emails.
I have set account, server, port (465) password and security SSL, all as they appear in my email client, but no reaction at all from the emails.

I'm afraid I'll have to cross-post as I have exactly the same problem with another script.
The logfile gives me this:

SMTP ERROR: Failed to connect to server: Network is unreachable (101)

I don't see where github and wiki come into it, as I use Gmail.
Adjustment: I just read in the help file about not using your Gmail password, but I have not found any Google app so far which lets me use its password for logging into my Gmail server on Maian Weblog.
I will definitely nee help on that.
Thanks.
