I can't help you with vpopmail, but simply using ipsvd-cdb most probably
won't do it.  I guess vpopmail first modifies /etc/tcp.smtp and then
runs tcprules to rebuild the cdb.

ipsvd supports such dynamic rules through the instructions directory, no
need to rebuild the constant database on each change.  Other
applications simply need to create or delete files in the instructions
directory to adjust the rules on the fly.

E.g., if an applications wants to have the variable RELAYCLIENT to be
set in the environment of qmail-smtpd for connection coming from
a.b.c.d, it simply runs

 echo '+RELAYCLIENT=' >/service/qmail-smtpd/peers/a.b.c.d

If tcpsvd runs qmail-smtpd through /service/qmail-smtpd/run, and it's
given the -t option, it can automatically remove this authorization
after a timeout.

relay-ctrl also may be an option, I'm not sure.
