I have a barracuda antispam appliance and I would like to turn on the individual user quarantine support but SME server causes all sorts of invalid accounts to be created. The reason is that qmail accepts e-mail initially regardless of whether or not a given e-mail account exists and only later does it reject the message. Because of this the barracuda thinks the account is legit an it creates a spam management account and tries to e-mail login info to the user "who doesn't exist" and this message bounces and lands up in my mailbox. I meed a way to have qmail bounce messages from the begining OR I need a ldap directory that the barracuda can query to see if uses exist or not . Please advise on how to handle this.
