[qpsmtpd] 0.81 Can prefork listen on more than one port?

[J]

I thought I'd move this out into a separate question, in case people were
tired of seeing my other thread...

I set my 'run' file to use two ports, but only the last one listed is
actually being listened on. I verified this with manual connections and
netstat on the server.

Does this mean prefork can only listen to one port, or might I be invoking
it improperly? Here's my run file:

============================================
#!/bin/sh
exec 2>&1 \
sh -c '
exec \
        /usr/local/bin/softlimit -m 100000000 \
        /usr/bin/perl -T ./qpsmtpd-prefork \
        --port 25 \
        --port 587 \
        --children 30 \
        --idle-children 5 \
        --renice-parent 5 \
        --max-from-ip 10 \
        --user smtpd
'
=============================================

Thanks.

J.
