Be sure to use correct port.
Default ssl is 465
You can also force ssl : just speficy protocole in host name "ssl;//hostname"

Hello sir, thanks for the reply.
I am doing this from global parameters under mailing. Is this correct ?

I can use both, One ssl and the other no ssl.
Any ideas ?

Yes

With or without SSL will change port to use.
Also, often non SSL nor TLS smtp server don't require login account.

Try and post screenshot of your config (hide confidential data) and result message of test.

Hello again,
i enclosed the image capture of the configuration frame.
Hope you recognize some errors.
Thanks in advance

OK,

Connection of SMTP server fails.
This wean you cannot reach smtp server through port 465.
Try port 25 (non secured) or 587 (TLS)

Also try and get Error logged on projeqtor log file, possibly there will be more explicit error here.
