Cause

 

2009 May 14 07:01:31 PDT (warning) ecelerity: [20867] smsrouting: ip address '10.10.10.1' used as an MX route
Cause: This message indicates that an IP address was used for MX lookup during delivery.
Example: If a message is sent using the outbound queue for an address like "[email protected]" this message will show up in the logs.
NOTE: After the first message the lookup will be cached so if it's necessary to reproduce it again then restart the MTA before doing so.

Cause: This message indicates a domain record for a domain is being added that has broken routing information, meaning that an NXDOMAIN response has been received. 
Example: A domain that has a broken MX record. If nslookup is run against the given domain the following response should be seen:  ** server can't find broken.qa: NXDOMAIN
