Actually, this probably is not that hard.  The IMAP C-client available from U.Wash
already does this.  Their documentation states:

    Network protocols supported by c-client drivers are the Internet
    Mail Access Protocol (all versions: IMAP4rev1, IMAP4, IMAP2bis, and
    IMAP2); the Post Office Protocol (version 3); and the Network News
    Transport Protocol (NNTP).  In addition, c-client also supports NNTP
    and the Simple Mail Transport Protocol (SMTP) for mailbox transport.

They also have drivers for local mailboxes (mbox/maildir).  Finally, they state it
should not be hard to add drivers for database backends.  The license is quite
unrestricted . . . .

The (rough) list of supported functions (implemented in PHP3) is available at
http://www.php.net/manual/html/ref.imap.html.  Might give you some ideas for the API.

Andreas
