Er, "no" to pretty much everything you wrote.  Sorry.

Perl <=> MySQL is *pretty* straightforward.

There is a lot of code out there that you can crib for examples.

I think it would be FAR easier to get to grips with Perl <=> MySQL than 
to re-invent the wheel and hack up your own database.

Re: in-memory database for greylisting.  I don't think this is a good idea.

This has been thought about by those who have experience of greylisting 
and know how it needs to work.  Greylisting requires a persistent (i.e. 
on-disk) database.
