Generally, an MTA should transfer messages, not play Syntax Police. > Anyway, all in all what I object to is "The other addresses in the > message were syntactically valid and have been passed on for an > attempt at delivery." This is exim's documented behavior, the error message is pretty clean. Kindly take this upstream; I am neither going to take this Upstream myself nor am I going to modify this part of exim's behavior in Debian until Upstream says it's ok to do so. > At least please tell me how to configure exim4 to cause the whole > thing to fail. Thanks. I don't know how to do this. Please ask on one of the support mailing lists. > I found some commands, maybe this: > # Deny unless the address list headers are syntactically correct. > # If you enable this, you might reject legitimate mail. Sounds good. > but I only want it to happen on outgoing mail, not incoming. Exim does not know whether a message is "outgoing" or "incoming". A message always comes in first and goes out last. You need to modify your ACLs to give them a hint about when is a message outgoing or incoming. I guess that you think "outgoing/incoming" with respect to your site, so an outgoing message might be identified by coming in from an internal IP adress or via authenticated SMTP, and an incoming message might be identified by being addressed to one of your local domains. Once you have identified a condition that says "this message is outgoing in my definition", add verify header syntax. > * exim4/dc_eximconfig_configtype: mail sent by smarthost; received via > fetchmail No idea what you are trying to say.
