Rejected addresses

[briansrapier]

I've searched the forums, but have not found a conclusive answer to this issue. I have a user that is attempting to send a message to an outside domain through the Zimbra client. When hitting send she gets:

Critical: Message not sent; one or more addresses were not accepted.
Rejected addresses: mary@domain.org

I ran an nslookup/dig against the domain and they have a valid mx record:

Server: 10.10.56.20
Address: 10.10.56.20#53

Non-authoritative answer:
domain.org mail exchanger = 10 SMTPGATEWAY.domain.org.

Authoritative answers can be found from:
domain.org nameserver = NS15.WORLDNIC.COM.
domain.org nameserver = NS16.WORLDNIC.COM.
SMTPGATEWAY.domain.org internet address = xxx.xxx.xxx.xxx

But 'zmprov gd' returns:

ERROR: account.NO_SUCH_DOMAIN (no such domain: domain.org)

I have DNS lookups enabled in the admin UI.

Have a look through the forums for 'mynetworks'.

Thanks for the tip, but that doesn't appear to be the issue. Running ' zmprov gs `zmhostname` | grep zimbraMtaMyNetworks' returns nothing, so I'm obviously using postfix defaults:

$ postconf -d mynetworks
mynetworks = 127.0.0.0/8 10.0.0.0/8 10.10.22.10/32

(10.10.22.10 is my server, but I think the setting is rather redundant.)

What does Zimbra use to verify a domain when using 'zmprov gd'? It doesn't make sense to me that DNS lookups pass but that test fails. I don't see the connection between that and the 'mynetworks' or 'zimbraMtaMyNetworks' settings.
