Running qmail-smtpd on multiple ports

[up@3.am]

I had a customer that was complaining about some of his users not being
able to relay outgoing mail when they're on wireless networks at hotels,
due to port 25 being blocked. I don't currently use any SMTP auth (just
vpopmail POP before SMTP auth), so I just ran another instance of
tcpserver-smtpd on another port, complete with the same DNSBLs and used
the same tcp.smtp.cdb file.  I do not use daemontools.

It tested fine, but now I'm getting complaints of multiple duplicates of
inbound messages on that server.  Not sure they're related, but if there's
any insight, I'd appreciate it.
