To keep some of the Sun's internal processes rolling my crontab(4) has accumulated a number of scripts that are run daily. These scripts send out emails of anything from a "gentle reminder" to gory details of process steps to follow.

In return for that service, a dozen or so vacation auto reply messages would get bounced at me automatically everyday when ever these scripts run. Looking at my mails I know who is on vacation or who is traveling.

So far I had a server-side filter that would filter out such responses. However is there way to stop these vacation auto-replies at the source?

It seems there is a way to tell the auto responders to ignore sending a reply to a mail, if the mail contains the header:

Auto-Submitted: auto-generated

Headers indicating an email to list can also suppress the autoreplies:

Precedence: list
