I have a zimbra installed in a local network and need to send emails through our ISP mail server. I have tested this feature before with no problems, but this one doesnt accept the autehntication.
My version of zimbra:
Release 5.0.2_GA_1975.openSUSE_10.2_20080130231825 UNKNOWN FOSS edition
I think the problem is that the target server is an exchange.
The authentication mechanisms that the target server shows are:
Connected to smtp.exchange.telepac.pt.
Escape character is '^]'.
