According to the man page, the value 1 seems more appropriate here as everything > 1 is documented to DO a rewrite unless DKIM is used. So I set it to 1 and first test seems to work.

[courier-users] Disable adding own hostname to sender's address
Hello. Courier adds it's own hostname to From- and To-Headers when they are syntactically broken. This is documented in courier man page at "defaultdomain". But I did not find a way to avoid that. If I leave this file away, the "me" file is used. What I want: Sent mail from local users (via sendmail CLI) should have the hostname appended. But mail from remote (spam) should not. Is this possible?
