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.

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.
