Wrapper scripts to various mail agents

Only needed if your system does not provide a local MTA (e.g sendmail) and/or a POSIX mailx compatible mail command.

To activate, choose a suitable one then place it somewhere in the path (/usr/local/bin is recommended), name or symlink it to mail and give it execute permission to anyone.

To use them with crond, you may need the cronmail converter script, which can accept sendmail-formatted mail and convert it into a suitable mailx call. You can usually set this script as a mail sender for crond using the CRONDARGS environment variable.
