I have installed the latest version on Zimbra 4.5.3 OS ( zcs-4.5.3_GA_733.SuSE10.tgz) on a SUSE Linux 10.2 server according to the instructions I found in the Forums.
All is working well and I can receive mail and access it from the Web interface as well as through Outlook 2003. I can send and reply to emails through the web interface but not through Outlook. I receive this message in outlook: The following recipient(s) could not be reached:
'XXXXXXX@gmail.com' on 3/14/2007 4:29 AM
554 <XXXXXXX@gmail.com>: Relay access denied
I tried setting the relay to localhost but was not able to send emails through the web client.
Does anyone have an idea how to configure zcs so I can send mail throgh the web client and outlook?
