Does any one have tried to limit users webmail access to certain ip address only and not globally anywhere.


This is important to protect certain sensitive informations are being leaked out to outside the company.


It with Squirrelmail Ip plugin but still users are accessible via any POP3 clients...

Hence can you give me a solution to,

either implement IP based limitation or User based limitation to allow or disallow their activities based on their roles


Thanks,
