email bouncing problem

[powrrrplay]

Hello, I can not figure out how to fix this problem.

I have a virtual domain set up, mail.virtualdomain1.com and some user accounts
ie., user1, user2, ... etc

external mail incoming to user1@mail.virtualdomain1.com works fine.

same external mail incoming to user1@virtualdomain1.com gets rejected, zimbra log says postfix NOQUEUE.

I have tried setting up secondary MX records for virtualdomain1 as mx virtualdomain1.com and setting a domain alias in zimbra for mail.virtualdomain1.com as virtualdomain1.com but still get the NOQUEUE problem. help???

i have split dns and set the external mx record for virtualdomain1.com and
the internal dns set for mx virtualdomain1.com

dig mx virtualdomain1.com shows both mx records on the zimbra server.

help!

Not sure if this information helps...
mail.virtualdomain1.com has an alias of virtualdomain1.com and

In the MTA these check boxes are not checked.

- enable DNS lookups
- Hostname in greeting violates RFC (reject_invalid_hostname)
- Client must greet with a fully qualified hostname (reject_non_fqdn_hostname)
- Sender address must be fully qualified (reject_non_fqdn_sender)
- Client's IP address (reject_unknown_client)
- Hostname in greeting (reject_unknown_hostname)
- Sender's domain (reject_unknown_sender_domain)
