It can call either spamassasin and/or a virus scanner on all incoming mail. It integrates seamlessly with sendmail and spamassassin. Neither need any config changes to work with MailScanner. I believe it also works with Postfix and Exim but I don't use those. MailScanner uses your MTA to receive the mail, pulls it out of the receive directory and scans it, then moves it to a separate directory for your MTA to deliver. I would assume you could use sendmail's mailertable to forward to the other server? MailScanner is very easy to setup. Gerry
