Mail seetings SMTP Joomla

Mail seetings SMTP Joomla

Hi,

I am trying to set up the smtp mail settings in Joomla 3.4 to use zoho. I configured it with no luck.( I have the two factor authentification OFF). The contact form in the web claims  SMTP connect() failed.

 Nevertheles, I configured the smtp settings with a google apps account and it is working perfectly.

Outgoing Server Name: smtp.zoho.com
Port: 465
Security Type: SSL 
Require Authentication: Yes. 
mail  ...... and password ........

I really do not knwow what I am missing.

Many thanks in advance,
Marc
