I have an installation with multiple domains hosted on a server with a hostname in an entirely different domain. For reasons relating to other services on the box, changing the hostname is not an option, but I want postfix to use one of the hosted domains as the basis of the 'myhostname' value for postfix (it would be smtp.domain.com). Is there a way to get zimbra to use something other than the hostname of the box for 'myhostname'?
I am running Release 7.1.3_GA_3346.RHEL5_64_20110928134520 RHEL5_64 FOSS edition.
Thanks in advance for any and all advice!
