Hello all,
I have Zimbra 5.0 RC1 installed on a Fedora 7. I send an email to myself at different addresses within the same To: field, here is the result:
GMail: received email inside inbox
Work Email: received email inside inbox
Yahoo: No email received at all , not even in junk folder
Hotmail: no email received at all, not even in junk folder
I didn't get any bounced messages from Yahoo nor Hotmail.
No email on out-going queue within Zimbra.
I've check the reverse DNS on my server - it is valid that is FQDN.

Previously, without the reverse DNS on the server, Yahoo put the email inside the junk folder. Hotmail doesn't even accept the email at all.

Received: from atlas.alliedexpress.com.au (atlas.alliedexpress.com.au []) by mx0.grr.com.au (8.13.1/8.13.1) with ESMTP id lADLobd6021488 for <xxxxx@alliedexpress.com.au>; Wed, 14 Nov 2007 08:50:37 +1100
Received: from localhost (localhost.localdomain []) by atlas.alliedexpress.com.au (Postfix) with ESMTP id 8AF4F1C802FA for <xxxxx@alliedexpress.com.au>; Wed, 14 Nov 2007 08:09:15 +1100 (EST)

Looking at the email route path, the destination mail server received from a FQDN. Does the first path of the route that has localhost.localdomain matters at all?

Any assistance would be appreciated.
