The reject route only triggers for UDP traffic. So carp (which runs inside
the kernel) and ospfd (uses a raw socket) are not affected. On the other

and when sending all packets are discrded.
Thanks for the clarification Claudio!
May be a suggestion, a quick addition to man 8 spamd in regards "to
enable ip multicast on the systems" might be welcome. I sure overlook
that for sure and looking at the man page again. I see no reference to
it. Obviously, I should have thought about it, but just didn't. I assume
I wouldn't be the only one going forward either.
I prefer to add a specific host route to 127.0.0.1 to let specific
multicast traffic through the box. ripd -- as it already plays around with
the routing table -- add such a route on startup but I think that's
overkill for spamd.
Good inside.
