Ok, a proposal for supporting additional mail agents : In /etc/sysconfig, we ditch 'sendmail_flags', and go to 'mailer' and 'mailerflags'. In the startup file for each new MTA, which is installed in /usr/local/etc/rc.d/, check the 'mailer' variable, and only start the MTA if the 'mailer' variable matches. The local startup files are read with all of the /etc/sysconfig variables defined, so you don't have to read it yourselves. The comment in /etc/sysconfig should reflect the mailers that are available as options, and reference the (upcoming) handbook entry for same. How does this sound? The /etc/sysconfig changes (and some minor /etc/rc changes for the sendmail case) are nice and straightforward and I'll happily do those if this is accepted. > Warner -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
