vuserinfo-compatible check_delivery

[Aaron Bell]

Does anyone have a version of check_delivery that is set up to work with 
vpopmail's vuserinfo? I've tried Bryan Scott's from a while back without 
any success, and I've noticed that there's been some discussion on using 
vuserinfo in check_delivery (for those vpopmail users who don't use 
MySQL), but I'm unable to find such a plugin?

Any takers? Thanks.
