Re: Safely executing your mail filter?

| So all incoming mail that comes to my domain gets put via qmail into a
| perl script and custom filtering is performed.
|
| Occasionally an error makes it's way into the perlscript and it fails to
| run. When this happens I lose email.
|
| I would like to ensure that this doesn't happen.
|

Are you talking like syntax errors in the script, when a new rule is
fat-fingered? I test this by simply executing the script from the command
line. If all's good it should just wait on stdin.

Any more convaluted errors might be caught with a shell script like you
mentioned.
