--- Comment #1 from Bryan Drewery <bdrewery@FreeBSD.org> ---
The problem is that logger((1) uses capsicum now which ends up forwarding the
entire message to syslog(3) which then adds its own hostname. syslog(3) does
not support passing a hostname.
If using logger -h then capsicum is disabled and the hostname is sent in a
direct socket.
