Accessing my relational Database through a layer of JDBC

Hi,

In my application, I am storing mails in my own particular format in a
relational database. I would like to access it via POP3(SSL) and a JDBC
interface I would adapt to the needs of dbmail from what I have already.
Could this be done with dbmail - anybody has done something similar already?

Many thanks for any hints in advance!

        Regards  Ralf

P.S.: As a newcomer to this list, I hope this question hasn't been asked
before - somehow I found the archives, but unfortunately no search function
for its >20 MB...
