Sendmail won't run rt-mailgate

I did check the FAQ and make sure I have the symbolic
link for rt-mailagte as follows:
ln -s /usr/local/rt2/bin/rt-mailgate /etc/smrsh/rt-mailgate

I also check to make sure we did set up correctly in /etc/aliases
and “newaliases” but the mail message still got returned with the
following error:

----- The following addresses had permanent fatal errors -----

“|/usr/local/rt2/bin/rt-mailgate --queue temp --action correspond”
(reason: service unavailable)
(expanded from: temp@geneva.garmin.com)

----- Transcript of session follows -----
smrsh: rt-mailgate not available for sendmail programs
554 5.0.0 Service unavailable <<ATT1037486.TXT>> <>

Here are some notes:
(1) RT server used to be able to handle mail before.
Then a couple of days ago, RT server had trouble rebooting
itself, so we did a hard reboot. (reset the mahine by pressing the
button) The hard reboot failed a few times at system
initialization. We then found out the file "/etc/rc.d/rc.sysinit"
had been set to read-only. After changing the access mode,
it thus rebooted successfully.
(2) What is weird is - it waited for almost an hour to return the
error “Service unavailable”. In the past, if we mistyped
the queue’s correspondence address, it got returned
almost immediately.

Anyone has had similar experience or solutions?

Thanks.
