Quota Limit

Target :

I did my own little script that allow users to be alerted when users are too close to their quota limit. You can set-up thresholds to determine when a user is in a warning, critical or ok state.

This script is, I think, ideal for a cronjob.


Thanks to Rick van der Zwet, there is a new version !!

Besides, I want to thank Philippe Lizon to correct a minor error :-) (in the v0.1)


Examples :

./quota_zimbra.pl -warning 87 -critical 90 -mail yes

more information :

./quota_zimbra.pl --help

I hope it could be usefull for some administrators :-D

Please excuse my english level and my wiki presentation ;-)



The script quota_zimbra.pl v0.2


#!/usr/bin/perl
# quota_zimbra.pl : 	this perl script allows the user to know if his current mail quota is a warning state...
#			the state is determinated by the thresholds (in percent) you set

NOTE: The quota will be set active on 5th of September 2007, this message is a warning only

Hi ###NAME###,

Sorry to bother you, but your mailbox is in a ###STATE### state, which means 
more than ###STATEMAX### percent is used.
Please make some space or you will not be able to receive email anymore.

You are using ###SPACE### and the quota is set to ###QUOTA###

Some tips of reducing your mailboxsize:
* Empty your trash folder
* Make a local backup of some mesages

Best regards,
Your quota reminder
