Delete old emails or just old junk emails for one or all users

[Nahoo]

I have created a nice script that deletes old emails for either a single user or all users.

It can also handle junk/spam emails only - which will also help to keep the account space usage down.

Usage examples:

A single user, with emails a year or older:
sh ./delete_old_emails.sh someuser 12

A single user, with junk email to delete, 3 months or older
sh ./delete_old_emails.sh anotheruser 3 junk

All users, with junk email to delete, 6 months or older
sh ./delete_old_emails.sh all 6 junk

This can easily be set to run using CRON.

#!/bin/sh
