I am getting quite a bit of email from email@example.com and it's going into the deferred queue because the lookup on localhost.localdomain is coming up with an incorrect address.
[root@zimbra zimbra]# nslookup localhost.localdomain
It's trying to use 220.127.116.11 to send the email. Could anyone tell me what it's using the wrong ip address for localhost.localdomain and can I set it somewhere in the zimbra config? 192.168.254.30 isn't right either but that's something I could work with at least.
