Dear Maintainer, I am using Debian 10 and I am bulding a server with a mail.someurl.com hostname and an MX entry for someurl.com. I have setup myorigin = /etc/mailname and /etc/mailname has someurl.com as an entry. If I test it with echo "test"| mail destination-address@gmail.com (mail comes from the mailutils package) I unfortunately still get the johannes@mail.someurl.com source address. Greetings, Tobias
