I don't see a problem with what you're trying to do. The key is to set up sendmail first so that it does what you want ie. forward your incoming mail to the RH box and use it to relay to the two internal servers. I'm assuming that your firewall is being used to select which server should get the appropriate mail. You would need to change this to forward all mail to the RH server and have it scanned there. This box would quarantine any virus' and relay clean messages to the other servers. Check the sendmail doc's but I believe you use sendmail's mailertable to accomplish this. All outgoing mail is just pointed at the RH box which is setup to allow relaying from your internal servers. The beauty of MailScanner is that it doesn't need your MTA (ie sendmail) to be modified. MailScanner uses sendmail to receive the incoming mail, then pulls messages from the queue, calls the virus scanner to process each message, sticks those with virus' in a quarantine directory, does the appropriate notification, and passes clean messages back to sendmail for delivery. You would setup sendmail on the RH box first. Once that's working then install MailScanner, turn off the sendmail daemon (MailScanner will call sendmail as required), and turn on MailScanner. MailScanner has many options that can be used to configure it the way you want. I suggest you subscribe to the MailScanner list. You will get detailed instructions there on the best way to set this up. I know there are people doing exactly what you want there. -- Gerry "The lyfe so short, the craft so long to learne" Chaucer -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
