Read all folders from remote mail account ?

Hi.

First... excuse my english !!!

I admin many remote mail accounts for my company with a maximum of 50 MB for each mail account.

I want to write a VB.NET (or VB6) program to access each account, read size of files in each folder (inbox, sent items, outbox, trash, ecc.) and calculate the total size.

Any suggestion ?

Thanks. Peter
