We have installed Lyris ListManager on a Redhat AS 3 server. It uses ports 25 (for mailing) and 82 (for web-based admin). We also want to run Sendmail on this server so that mails can be sent using the PHP mail() function.
How do we configure an alternative port for the Sendmail server? The second (major) problem is that the Sendmail user was deleted as part of hardening the system (since Sendmail was not need at the time). Now, we find that starting and stopping Sendmail is not smooth at all. The Sendmail client (sm-client) shows its status as "service stopped but subsys locked".
Any hints/prods in the right direction are welcome.
