We are a managed server hosting company, not a Cable/DSL/T#/Dialup provider. The only way mail gets sent out of here is Webmail, FormMail and Mail exploder.

I'm doing the best I can, and I'm sure to the DETRIMENT of the user, to cut down on the spam, but short of having someone physically inspect all email for spam and backscatter I really can't do much else (Except get the user to have a local Webmail which I know they don't want).
