I have Zimbra setup and running. Everything works fine except for the remote users.
I have some users outside the LAN connected via ADSL. I need to configure outlook to send email through the zimbra mail server.
Mynetworks are for local networks for securityu reasons.
i need to configure in outlook smtp : zimbra.domain.com, with authentication .

configuration is:

zmprov gs zimbra.domain.com |grep Auth
zimbraMtaAuthEnabled: TRUE
zimbraMtaAuthHost: zimbra.domain.com
zimbraMtaAuthURL: http://zimbra.domain.com/service/soap/
zimbraMtaTlsAuthOnly: TRUE

zmprov gs pinus.dgrf.min-agricultura.pt |grep Mode
zimbraMailMode: https

The idea is to configure in outlook to have
My outgoing server (SMTP) requires authentication
Use same settings as my incoming mail server

I have in the server:
Enable authentication
TLS authentication only

but is not working

Any idea?
