Time limit on whitelisted IP addresses

[2webmaster]

Hey, It would be useful if we could set a time limit when adding an IP address to the whitelist or blacklist. e.g. when a client has trouble configuring their email client, we can whitelist their IP address for 24 hours while they get the right details configured to avoid being blocked. After the 24 hours, I360 automatically removes the IP from the whitelist. Thanks
