mail_add.php returns 500

Quote from zddr

Hello,
on our new server with the most recent i-MSCP (config unchanged) adding an E-Mail-Account to a domain returns a 500-error-page. The Mail-Account is successfully added though. Looking through the Apache Error-Log seems to indicate that the error is connected to our SSL-Certificate...
I'm not sure if mail_add.php should answer that with a 500 though, especially since the action is successful.
Below is what I found in the log.

Hello

This occurs each time you add a mail account?

Hey,

thanks for your answer.
Yes, this occurs every time a mail-account is added on this server.

Some further tests show that this error also occurs without using HTTPS... and I forgot to mention that we use php5-fpm, sorry about that.

Ok, I'll investigate. If i can not reproduce, I'll ask you to install teamviewer

Re;

This the same problem as described in http://trac.i-mscp.net/ticket/925
