Hello Thomas,
Yea, i am imagine myself managed a google sized email system..
1. how do you distribute into different assp server?
2. SQL? i never know assp use it.. is this SQL some sort of flatfile
database?
3. challenge is always great. :) push one to a limit.
It will great to have some tutorial/documents to give a guide on how to
accomplish it.
Regards,
Joseph
