I am not saying there is anything wrong with your experience. I understand that people
having worked with
MyISAM might have a different mindset. But they at some point did make a decision to use
InnoDB. I think
this is the time when I would ask myself a question: where is it that my data will be

I didn't have a pleasure to use dbmail. I presume it does something with mail users.
Thinking logically, if I got rid of my biggest mail user, I might eventually get another
even bigger one, which would consume the same space vacated by the deceased user.
So why would I want to give up the space then?

If the people do not have the knowledge to do exports/imports, the brand new and cool
file management feature will not help them either. Essentially, the instructions how to
that feature are written in the same book as the instructions how to do export/imports.
consider it as given that people would never read, it is a dead end.
