Restrict mails to/from specified mail server(s)
I checked this but there is no way to do so before, and I am not sure whether the latest version is enriched the power, so here is my question:
Can I restrict my users just allowing them to send mails / receive mails from specified SMTP servers (eg. firstname.lastname@example.org) from the Internet (not hosted in the same network)?
Details: We want to allow the users @ZCS can communicate with the other parties that are using the outside pop/smtp service, but we don't want our users to communicate with the rest like their friends, personal email address...etc
Anyone know how to do so? Many thanks!
