I am in the process of installing Zimbra on a Ubuntu 8.04 LTS server, I have never used Zimbra before and thought I would give it a shot.
The process seems fairly straight forward but I am unable to find information on setting a smart host. The ISP here in Australia blocks port 25 outbound so I need to know how to do smart host/mail relaying. I know under sendmail all I needed to do was edit the sendmail.cf file and add the host name after the DS statement and all was good. But Zimbra doesnt use sendmail and I cant seem to figure out how to do this in postfix/Zimbra.
Is there any information that any one can give me to resolve this issue.
