Problem with sending email on SMTP

I do not use OVH, but I had some problems with SSL.

If you use a Self Signed Certificate, CodeIgniter do not connect. Then you will need some hacks or some external library, https://github.com/ivantcholakov/codeigniter-phpmailer is a good choice. Also I have worked on an IMAP Library in https://github.com/natanfelles/codeigniter-imap.

Is not the correct SMTP Host the mail.ovh.net?
