Not necessarily. While I have no yet used the feature, iptables
permits firewalling on userid. I presume this includes wether or
not a program can listen on a port, right? (and all the other
fun things).
If so then all you'd have to do is deny external access to port 2525
and only permit mailuser to listen etc on it and you're set.
