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?
2. What can I do about it?
Thank you,
Lucky
