How can I resolve problem with SMTP connection ?

Hello,
It's been a few hours that I try to set up my mail sending system but the connection with SMTP does not work.
Here is the error message:
"Resolving SMTP server domain" smtp.zoho.eu "...
Connecting to SMTP server "smtp.zoho.eu" port 465 ... "
Look at the two attachments.
Please help me ....
Looking forward for your response.
