I want to make the following request for my account:

Can you please increase the number of IP ranges I can define under  Control Panel >   Email Routing > Incoming Gateway  to 10 [I can add 3 at the moment] ?

Reason for this request: I am using an email filtering system that can send from 10 IP ranges and if I can define these 10 ranges in Zoho mail I can utilize the " Reject mails from Non-inbound IPs" option and secure the account even more by rejecting mail from all other unrecognized IPs.

Love the service.

Thank you.
