Find and fix a small php error

I know that you "adore" the self-written engines, so catch the task:

I am in the process of finding a programmer after the "departure" of the old. Ive been doing my best for a long time (I can do it in small things), but I still have something and I cant win. In general, everything is how you "love"))

Urgently need to win > 1 bugs. Theres a small joint, even there is a backup worker, but do not want to roll back at all as a lot of changes have been done ...

I will give preference to the person who will declare that he is well versed in such things as smtp, as there is a goal in the next couple of days to spin to my self-written engine PHPMailer to work, on the subject of which we agree a separate task.
