check your maillog in /var/log/ anything similar to this in there:
---------------------------------------------------------------------------

Nov 17 04:02:43 Turtle sendmail[4717]: My unqualified host name (Turtle) unknown; sleeping for retry
Nov 17 04:03:07 Turtle sendmail[4501]: unable to qualify my own domain name (Turtle) -- using short name
Nov 17 04:03:07 Turtle sendmail[4501]: hAHC37RE004501: from=root, size=2273, class=0, nrcpts=1, msgid=<200311171203 hAHC37RE004501 Turtle>, relay=root localhostNov 17 04:03:07 Turtle sendmail[4501]: hAHHLS433: to=root, ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=32273, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]

---------------------------------------------------------------------------
make sure of a few things, check /etc/sysconfig/network it should have
a line like this:
HOSTNAME=turtle.localdomain

check /etc/hosts for lines like this:
127.0.0.1       localhost.localdomain   localhost
127.0.0.1       turtle.localdomain      turtle
Note the . in the hostnames, sendmail is picky about seeing a domain (aliases ok)
Also someone told me:
127.0.0.1       localhost.localdomain   localhost turtle.localdomain turtle
Is a better way to write it due to resolver code though, I've not had problems with my way yet, If you do you know what to try.

Check /etc/hosts.allow if you have tcpwrappers on
sendmail : 127.0.0.1 localhost.localdomain

By default RH configures sendmail to only accept connections from localhost
so any changing of things throws it for a loop.

good luck.
