[WBEL-users] Ever hear of this type of setup/config?

[Jeff Maze]

Hello,
	I don't remember if it was on this list, but I remember reading
somewhere that someone setup a sendmail/postfix server running as a
secondary mail server and to help curb the amount of dictionary attack
e-mails (TO: bob1@domain.com, bob2@domain.com, ... bob57@domain.com, etc.),
they had the sec server look up valid e-mail address in a database (I
believe via MySQL).  If it was valid, then it forwarded it onto the primary
server; if not, it dumped it.
	We're getting a lot of dictionary attack e-mails through our sec
server (running WBEL) and would like to implement something like this (if
possible).  Thank you for your time and attention.. -Jeff
