Exchange Receive Connector query
I have been asked to allow larger emails to come into the organisation from a particular client. But I just want to allow larger emails from that client and that client only. having done some digging I set up a new receive connector and allowed 30Mb max receive size for that connector but I have a query for the network settings tab. Should I enter the Ip addresses of the clients public available DNS servers? - or otherwise how will our exchange server allow the sending from the client domain only through that receive connector? is this the correct ip addresses to configure?
thanks in advance for any help! :)
