How to restrict some user to send mail to external mail id’s (gmail, yahoo, etc) ..
I have two groups in my organization
EXTERNAL and
INTERNAL, I have to restrict the internal users to sending and receiving mails through internet only they have to access internal mails, but external they have to send and receive all mails through internet and intranet, both the groups should be in the same domain.
Please suggest me any option in Zimbra or Shell script for the Requirement.
Thanks in Advance.
