<br>> Billy Pumphrey<br><br>That should do it. I would limit connections to port 25 at the Exchange<br>location to incoming ONLY from the IP address of your MailScanner<br>machine. I would give myself ssh access to the MailScanner machine.
<br>Might not be a bad idea to move ssh to a port OTHER than 22.<br><br>Mike<br>--<br>MailScanner mailing list<br><a href="mailto:mailscanner@lists.mailscanner.info">mailscanner@lists.mailscanner.info</a><br><a href="http://lists.mailscanner.info/mailman/listinfo/mailscanner">
