Has anybody used qmail with MS SQL 7 ?

[Sebastian Pilafis]

 Hi
 I would like to know if someone has used qmail reading usernames and
passwords from a table in MS SQL 7 using openlink's ODBC driver?.
 I have learned that it can be done modifing vpopmail to use this driver,
but i would like to know if anyone have already done it succesfully, and,
idealy, if i can download a vpopmail that alrready has this changes done.
