Hello!

We are currently using FirstClass server (http://www.centrinity.com/) and it seems to work just like Exchange: it accepts all mails and sends NDNs if the user name is not found. We are quickly running out of licenses, when spammers try to guess user names on our site (e.g. joe, joe2, joe3, etc.) and so NST needs to be restarted every day for spam filtering to be effective. Does anybody know how to make FirstClass not to accept mail for unknown users or to work around this problem?

Another problem with licenses is that many users use aliases, and we need double amount of licenses. But maybe it's impossible to implement alias checking in NST?

The "Restrict Spam Checking" feature in the Admin wizard lets
you define the set of recipient addresses you want to be included
in the spam check.

Since NoSpamToday! works as a transparent SMTP proxy it can not
tell which recipient addresses are aliases and which are not.

We also run firstclass, we have all of our addresses listed in 'recipient domains 'and 'restrict spam checking', this way any unknown users are rejected by NST. If you only list the users in 'restrict spam checking' then first class will reject the unknown users (unless you have setup an account with a wildcard). Provided you have sufficient licenses for each address listed in NST, we have found this very effective.
