odd MX entry error in zone file

[Bruce Johnson]

I added a new zone to our domain today and ran named-checkzone and got the following when it ran:

named-checkzone -t /var/named/chroot Pharmacy.Arizona.EDU /etc/Pharmacy.Hosts
zone Pharmacy.Arizona.EDU/IN: getaddrinfo(xxxxxxx1.barracudanetworks.com) failed: System error
zone Pharmacy.Arizona.EDU/IN: getaddrinfo(xxxxxxx2.barracudanetworks.com) failed: System error
zone Pharmacy.Arizona.EDU/IN: loaded serial 1762233835
OK

These are our Barracuda cloud service addresses set as MX entries in the zone:

;MX records
;pharmacy.arizona.edu. 3600	IN	MX	99	barracuda.pharmacy.arizona.edu. ;message exchangeer
pharmacy.arizona.edu.	3600	IN	MX	10	xxxxxxx1.barracudanetworks.com.
pharmacy.arizona.edu.	3600	IN	MX	10	xxxxxxx1.barracudanetworks.com.

Mail is working and the OK at the end of the named-checkzone output indicates that it thinks the zone file passes ok. 

I can resolve the actual addresses without an issue :

dig d256777b.ess.barracudanetworks.com @elixir.pharmacy.arizona.edu

And I don’t see anything in the logs about this.
