This message is seemingly lost in the archive, yet I did
receive a copy by the daemon, so I bring the matter up
once more.

I have again tested this patch with IU-syslogd and IU-logger
alongside Rsyslogd on a Debian system and it works very well.

Is there a sensible reason not to implement this? Expansion to
allow multiple UDP sockets, but no wild card, and possibly TCP
communication are best left for a later stage.

Best regards,
