Did you have /var/spool/postfix set to +S (check with lsattr) or mount
it sync?

jfs 1.0.5 is not exactly current. Neither is Linux 2.4.10.

Again, Linux 2.4.10 is not exactly current. If it was +S as per lsattr
or mounted sync, updating to 2.4.16 may increase throughput. What
journal mode did you use?
