The log entries below were culled from our Postfix 2.0/SuSE 9.0 log file which would seem to indicate that we have an open relay problem when the from address is empty (from=<>). I have relay_domains set and have tested it with a "real" address and it works, i.e., does not relay mail for unlsited domains.
Questions: 1. Is my analysis correct, i.e., is it relaying mail when the from address is null?
I don't think it is correct. From address <> is usually a bounce, an error
message from your mail server. In the logs you posted, I would have expected
to see a Connect line in connection with the mail if there were something
fishy going on.
Look further up the log and see if you can't find an entry with
from=
