Redirecting Syslog events from RHEL 6 to RHEL 5: is it possible to provide with the same event format?

For some reasons, we redirect syslog events from RHEL 6 (with rsyslog) to RHEL 5 (with syslogd).

On RHEL 6 in rsyslog.conf:

*.*                 @10.30.46.211

On RHEL 5 in /etc/sysconfig/syslog:

SYSLOGD_OPTIONS="-r -m 0"

On RHEL 6, the event looks like (/var/log/secure):

Oct 25 02:10:03 rh6q32 sshd[1849]: pam_unix(sshd:session): session closed for user root

On RHEL 5, the same event looks like (/var/log/secure):

Oct 25 02:10:03 rh6q32 rh6q32 sshd[1849]: pam_unix(sshd:session): session closed for user root

The difference is double using of host name (rh6q32).

The question: is it possible to get rid of double hostname?

Thanks,Yuri
