the message is totally malformed.

The sender must be fixed to emit correct format. It is a known problem with
some senders (sysklogd namely), but we have not yet provided a work-around
for it because that causes unnecessary performance loss on the rsyslog side.
However, thinking now about it, a special message parser module could be used
to solve that situation. That way, only those that actually have this problem
would need to bear the cost of the work-around. Let me think a bit about
this...

No, it isn't -- it was sent to a public mailing list and is probably archived
on a myriad of sites by now. Please note that as of the ToS of the mailing
list, we do not accept any liability. It would be decent to tell your mail
folks to turn off this disclaimer for list-directed mail. Thanks!
