Safe Mode and mail() function

Hello,

I ran into some trouble when trying to make RoundCube work with the mail() function : when PHP is set to run in Safe Mode, the mail() function won't accept the 5th parameter.

I think that this 5th parameter is not mandatory so I removed it (program/steps/mail/sendmail.inc, line 199) and it's now perfectly working.

Before :

$sent = mail($mailto, $msg_subject, $msg_body, $header_str, "-f$from");

Now :

$sent = mail($mailto, $msg_subject, $msg_body, $header_str);

I thought it could be helpful to someone so I wanted to tell the mailing list about that.
