You can have qmail (I presume you mean qmail-smtpd) listen to any
port you want, or any number of ports. What port it is running on
does not affect in the least it's manageability.

The INSTALL document describes how to start qmail-smtpd on port 25:
16. Set up qmail-smtpd in /etc/inetd.conf (all on one line):
smtp stream tcp nowait qmaild /var/qmail/bin/tcp-env
tcp-env /var/qmail/bin/qmail-smtpd
In that line, the first word 'smtp' corresponds to this line in
/etc/services:
smtp 25/tcp mail #Simple Mail Transfer
If you wanted to run qmail on another port, pick an unused port
from /etc/services, for example 2525. Create a line like this in
/etc/services:
mysmtp 2525/tcp #Simple Mail Transfer
Pick any name you like, as long as it's different that any of the
others.
Now, set up qmail-smtpd in /etc/inetd.conf, using this new service
you invented (all on one line):
mysmtp stream tcp nowait qmaild /var/qmail/bin/tcp-env
tcp-env /var/qmail/bin/qmail-smtpd
Send a HUP signal to the inetd process, and your changes will be
in place. See services(5), inetd(8).
The author does prefer that people use his tcpserver tool, rather
than inetd. See question 5.1 in the qmail FAQ. In that document,
the line:
tcpserver -u 7770 -g 2108 0 smtp /var/qmail/bin/qmail-smtpd &
is an example invokation. Again, the 'smtp' refers to the service
entry in /etc/services, replace it with 'mysmtp', or whatever you've
come up with...
