I want to start with zimbra mail server installations and create users.
But I don't know much about zimbra mail server.
My plan os starting is as:-
1) Installation of zimbra mail server.
2) Create new users.
3) verify end to end mail communications by sending mail from user1 to user2.
1) Can I create my domain inside my office, office will be having their own domain and proxy.
2) Can I send and receive mails from open cloud like yahoo.com, gmail.com etc and from private network like ibm.com, accenture.com etc
