But Ubuntu doesn't come with a postfix server enabled by default, so that's not really a concern, is it?
- JdeBP 10y agoUbuntu does, however. Here is its guide: * https://help.ubuntu.com/lts/serverguide/postfix.html https://help.ubuntu.com/lts/serverguide/postfix.html Here is where it is enabled by default: * https://git.launchpad.net/postfix/tree/debian/postfix.postinst#n169 https://git.launchpad.net/postfix/tree/debian/postfix.postin... And here is where the installation process auto-starts the server: * https://git.launchpad.net/postfix/tree/debian/postfix.postinst#n557 https://git.launchpad.net/postfix/tree/debian/postfix.postin...
