I've been getting a lot of bounces lately from spam with forged headers,
and I report them all as spam. I have my spam settings pretty loose, and
block most with RBLs & static, in-house blacklists. I get very few
false-positives, and most of those end up in my quarantine, where I can
add them to a whitelist. It's extra work for me, but still better than
spamming other innocent people, and ending up blacklisted.

I think for SPAM this is probably good because if it isn't SPAM, the
headers weren't forged and it may be nice to know that someone didn't
get the message. For instance, say you were sending some fairly
important message and you know that RR was disabled on their mail
system, you would have to assume they got it or worse, call them to ask
if they got it - "Yeah I just sent you an email, did you get it
derrr".
For AV stuff, yes, I absolutely agree, do not send messages back saying
the message I sent had a virus. I hate that because I know I didn't send
a message with a virus but some numbskull who happens to have my email
address in their contacts sent it.
