Rt-mailgate not working in rt-3.4.0rc3

We just installed a new RT installation on Fedora Core 3.
rt-3.4.0rc3
mysql - 4.0.23
Apache2
mod_perl 1.99

The install went fine. All modules loaded, no errors and we are able
to enter RT and define Queues, Groups, create tickets, etc. We also
installed RTFM-2.0.4.

Our problem is primarily with the rt-mailgate. We defined the rt and
rt-comment lines in /etc/aliases, put a sym link in /etc/smrsh to
/usr/local/rt3/bin/rt-mailgate, and made changes in the /etc/mail dir
to access, sendmail.mc and local-host-names. We ran newaliases and the
m4 commands to configure the changes.

All our messages to rt fail to get past smrsh. The errors we get in maillog are:

Jan 10 12:01:37 prospec01 sendmail[21674]: j09M8E4j015726:
to=“|/usr/local/bin/rt-mailgate --queue support --action correspond
–url http://localhost/”, ctladdr=support@prospec01.onerhino.com

dsn=4.0.0, stat=Deferred: prog mailer (/usr/sbin/smrsh) exited with
EX_TEMPFAIL

Any help with this would be much appreciated.

We are also getting some other errors but are not critical, I mention
them here because they may be related:
