Custom files in Email_Engines getting deleted

I've been using some custom .inis in the Email_Engines directory, but on updating SER recently they were all deleted. Can you allow these .ini files to remain after update, as in the Engines directory?

hmm you are right. It seems like I have that statement in my installer script to delete it. I wonder why I did that, but for next updates it was removed now and I also implanted some more fixes for this section.

You better use the appdir\email_engines folder from next update as that will not touched and also used in priority in case you have some engines names the same.
