Assuming that one's configuration has open relay, what does a log
entry for relayed mail look like?
It looks like any other mail, just it was received without authentication,
from unstrusted clients and sent to remote (not in relay_domains or
permit_mx_backup_networks) recipients that were entered by the sender (not
local recipients rewritten to remote in aliases or virtual_alias_maps).
I don't think I've any open relay, but I want to look and make sure.
I've searched for half an hour, and no answer came up. But, I did
find some hints. Specifically, I use this command to list all
outgoing mail:
grep relay= mail.log | grep -v relay=local
the "relay" means mail destination.
I can then use the message ID to get all the log information for each
questioned transaction.
Am I on the right road? Please disabuse me of any incorrect notions.
yes, that could help, but it's pretty much work.
I find it better to explicitly test server for relaying.
