Restrict sending fron ip to one domain users

[petramaldonado]

Hello everyone.

I would like to know if it is possible to make a configuration that allows users of a given domain to send from certain ip addresses.

It would be something like "users of domain example.com can only send from ip a.b.c.d and from f.g.h, k.

In this way, a user connected to a network with a private local IP address that leaves through a gateway (one of those pubic ips) could not connect his laptop at home and send work mail.

Thank you.
