Deferred Name server ...why? it is configured in sendmail.cf !!!

[Manuales]

Hi !!!
i have a problem with sendmail.
In sendmail.cf i configured D$j.patito.com and DS (mail server)

In nsswitch.conf is next:
hosts: files [NOTFOUND=continue] dns
services: files
protocols: files
networks: files
rpc: files
netgroup: files

When i make a test :
/usr/sbin/sendmail -v user1@patito.com

appears next message:
user1@patito.com.mx... Deferred: Name server: aaaaa.bb.cccc.dd: host name lookup failure

If i make a nslookup to aaaaa.bb.cccc.dd it responses correctly:
nslookup
unixserver@1# nslookup aaaaa.bb.cccc.dd
Using /etc/hosts on: unixserver

looking up FILES
Trying DNS
Name: aaaaa.bb.cccc.dd
Address: 111.222.333.444

unixserver@1# ping aaaaa.bb.cccc.dd
PING aaaaa.bb.cccc.dd: 64 byte packets
64 bytes from 111.222.333.444: icmp_seq=0. time=256. ms
64 bytes from 111.222.333.444: icmp_seq=0. time=257. ms

64 bytes from 111.222.333.444: icmp_seq=1. time=300. ms

what could be?? :(
