You are right, it doesn't make any difference in my setup. This works fine:

domain fidonet  /srv/ftn/outbound/fidonet  2
domain fsxnet   /srv/ftn/outbound/fsxnet   2
domain amiganet /srv/ftn/outbound/amiganet 2

I thought binkd wouldn't be able to figure out which zone number maps to which
domain, but it doesn't seem to be a problem.

$ poll 39:15/0
  12:59 [16912] BEGIN, binkd/1.1a-101/Linux -p -P 39:15/0
/srv/ftn/binkd/binkd.cfg
  12:59 [16912] creating a poll for 39:15/0@amiganet (`d' flavour)

If binkd's  parameter is intented to have the same meaning as
"the default zone" in FTS-5005 than using the same zone number for all "domain"
lines is the right configuration (and not a workaround). It is counterintuitive
though and the example binkd.cfg files suggests you should use the zone number
of the network.
