Problem with latest version of Mailscanner

(note to the mailscanner list: I'm top-posting due to the location of
the included files, I'm sorry, and I generally try to avoid that ...
the context is in the quoted section)
Cyrille,
I suspect that the problems are the two "SENDMAIL=" lines.
Unfortunately, I don't know anything about how these new configurations
are set up (I haven't updated my mailscanner in a while), so I'm CC'ing
the mailscanner mailing list in case I'm wrong (and some of my comments
are more directed at them, than at you).
I'm assuming that the "SENDMAIL=" lines are somehow over-riding the
MailScanner.conf entires for "Sendmail =" and "Sendmail2 =".
The problem is that neither of the lines mentioned below are clear as to
which MailScanner.conf item they are supposed to be. In
MailScanner.conf, Sendmail2 should be the ms2cgp script, and I don't
know how to set that in these new files you've sent. the "Sendmail ="
line should be your communigate pro compatability "sendmail" (
/opt/CommuniGate/sendmail ), however, this does not run as a daemon, and
it's hard to tell if one of these is trying to run as a daemon.
Most directly, what I would suggest is: don't use rc.MailScanner (nor
it's newer counter-part) nor the equiv. for Sendmail. Disable them.
(IMO, rc.MailScanner is riddled with assumptions about mailers, and,
IMO, that's poor coding)
I would, instead, create a new MailScanner start-up script (that goes in
/etc/init.d or /etc/rc.d/init.d or wherever redhat puts that stuff these
days) that just invokes "/opt/mailscanner/bin/check_mailscanner" for
starting, and just kills whatever is in
/opt/mailscanner/var/MailScanner.pid for stopping. Something like this:
#!/bin/sh
#
case "$1" in
'start')
/opt/mailscanner/bin/check_mailscanner
;;
'stop')
kill `cat /opt/mailscanner/var/MailScanner.pid`
;;
*)
echo "Usage: $0 { start | stop }"
exit 1
;;
esac
exit 0
That should be enough. Having MailScanner's rc file start or stop the
external mailer (such as sendmail) is an incredibly bad idea, and I
don't know why anyone started doing that. It breaks encapsulation, and
a host of other "good ideas" all for the sake of convenience ... never a
good trade. This is exactly the type of thing that is the target of the
old acronym "KISS: Keep it Simple" (with emphasis on the missing S
word).
Have MailScanner's rc file control mailscanner, and do nothing else.
Have CommuniGate Pro's rc file control CommuniGate Pro, and do nothing
else (or substitute in whichever mailer is in discussion). That's how
it should be.
Hopefully MailScanner still propperly listens to its MailScanner.conf
directives, though. If they've stopped having it do that, then I don't
know what to say. It may mean that new versions of MailScanner have
stopped being useable with CommuniGate Pro.
