Porting RoundCube to new backend

[madtantric]

Hi,
   How difficult/easy is to port RoundCube to use any email database (instead of
IMAP)?. I want to customize it to read messages from a DB rather than IMAP.
Like to hear about the feasibility before jumping into the code.

Thank you

Roundcube was not designed for doing this, but I think all you'll need to do is to rewrite/replace rcube_imap and/or rcube_imap_generic class.
