Actually, setting up multiple instances on one machine
was my first throught. I believe to have exactly the
behaviour I described, I would need one instance for
each VPN. However, due to the modular structure of
qmail I thought it would not be possible to run
multiple instances (e.g. listining on different ports)
on the same machine. How will one qmail-smtpd know to
which qmail-send it has to pass its mail? Is this
controlled only by the queue directory path? If yes,
could I run one qmail-smtpd which would be patched to
use different queue directories for the different
VPNs? Then I could setup one qmail-send for each VPN
and things would be fine. (at least as long as the
number of instances does not kill my machine ... a Sun
E250)
