Yes, that's correct. I'm sure you don't want vacation messages
distributed through the mailing list. :-)

That's bad, without question.

I often noticed the autoresponder doing stupid things. In case of "I
can't handle a message with a Mailing-List header" I suggest it should
exit silently with an error code of 0 instead of 100 because...
* 100 prevents the message from being delivered to the final recipient
* Nobody is interested in getting informed about a vacation message that
hasn't been created
Anyway, I wonder why your log notes this line as "deferral". Judging
from the source (I have autoresponder 2.0.3) it exits with 100 which
means "hard error" = "failure", while only 111 should generate
Hopefully somebody can bring some more light into this. I guess the
autoresponder's exit codes need some additional review.
