Oddball DNS issue: won't resolve hostname alone.

I set up bind9 on an Ubuntu box several weeks ago. Now, email on two
Ubuntu machines is broken. I get, e.g.

Dec 17 09:50:58 phoenix postfix/smtp[436]: 08D2A16A0E4: to=<ccurley at charlesc>, orig_to=<root>, relay=none, delay=8152, delays=8142/0.01/10/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=charlesc type=A: Host not found, try again)

But I can do:

root at phoenix:~# host charlesc
charlesc.localdomain has address

Trying the equivalent with dig, I get:

root at phoenix:~# dig charlesc

; <<>> DiG 9.4.1-P1 <<>> charlesc
;; global options:  printcmd

;charlesc.                      IN      A

.                       10662   IN      SOA     A.ROOT-SERVERS.NET. NSTLD.VERISIGN-GRS.COM. 2007121700 1800 900 604800 86400

;; Query time: 1 msec

;; MSG SIZE  rcvd: 101

Notice there is no answer section. Doing the same with
charlesc.localdomain returns a correct answer section.

resolv.conf is like so:

root at phoenix:~# cat /etc/resolv.conf
search localdomain

This just started happening this weekend.
