Hi,

Yes, $XYMSRV (or the recipient specified directly on the command line to
the 'xymon' client program) can be a FQDN, even in 4.3.30, and a lookup
will be performed.

It's fine to do this, just with the caveat that this introduces working
DNS resolution as a requirement for client log submission. This might be
an OK tradeoff if, as you say, you're doing migration, or have a floating
xymon VIP, or are doing other things with xymonproxy and need admin
flexibility w/o touching every machine.
