Depends on how the address is input.  If the address is encapsulated, I have
seen where it will be accepted, as if it will relay, but then it generates
an NDR.

Ok, but they should not be sending ndr's in response to notification
messages is my point. If relaying disabled, messages that are 'spoofed'
should not generate an NDR in my opinion. I mean, why should it send and
fail send and fail to hosts that don't exist just to say, 'invalid host' or
relaying prohibited or am I missing something?

They will still appear for standard, valid NDR's as well.

So I should ignore those if they are not causing any other problem?
I have followed all the suggested reccomendations regarding relaying.

That is your server NDRing the attempted relays back to the spammers. Since
spammers tend to use bogus addresses those messages will likely timeout
after three days as undeliverable.
