MailScanner v5 standardization

[Gao]

So we still use init start script and no systemd support? Lots OS moved 
to systemd although I don't like it.

As far I know, this should have no impact on sendmail/exim/postfix operation. From that I mean, “service sendmail restart” should have both the in and out processes restarted without issue. There is no need for MailScanner to start and stop them. I know for a fact this has no impact on using MailScanner with Postfix.

The check_mailscanner script that checks to see if MailScanner is running and then starts it if it is not running uses MailScanner’s internal method of starting a daemon that is portable across all platforms. This is already in use on all packages on every OS. Very basic and very effective:

One cron job in /etc/cron.hourly and one in /etc/cron.daily that each point to a single file in /usr/sbin. The file will read your cron options from /etc/MailScanner/defaults and will be called like this:
