> Would you guys be interested in writing a front end (similar to Mail 
Essentials) to Imail, that would implement the RBL, RSS and DUL?  Looks 
like you there are several potential customers on this list . . . .

==============

I think the most efficient way to get there is to use of the 
high-performance, proven open source MTA's (postfix, sendmail, qmail) on a 
FreeBSD or Linux dedicated box.  This  box would be a restricted relay for 
all Imail's domains.  All MX records point to this box, so all incoming 
mail gets scrubbed:

1. if destination MTA not in the domains to relay, reject

2. if reverse lookup of the ip address for MX record fails, reject

3. if in black hole, reject

(4. Reg Ex spam filtering, nice but optional, maybe later)

5. else, forward to Imail

This wouldn't have to be a powerful machine, and the software would be 
free. The above functionality, including RegEx filtering language, is what 
you get for $5000 at www.MailShield.com.
