Just double check your SSL changes in comparison to the above thread.

Hi It seems everything is correct as the thread you have shared with me, But I don't know why the email 

are not working. Did you have any idea, if the mails are not working on a script we can say that it was because 

of technical error, But from the roundcube also it was showing error message while sending. If you know any

fix please help.
