Re: [debops-users] nullmailer and envelope sender

For a large number of hosts you could solve that by creating a mail hub with Postfix to which all other hosts send their mail. Postfix could use its rewriting capabilities to masquerade the other hosts and send the mail on its way outside.

I suppose that the default version in Debian Stretch doesn't have that functionality, but there's a backported version which you are probably using?

I suppose that the 'debops.nullmailer' role could also use this variable, so that in the future change like you propose could be possible. Or, for now, you could see if adding the 'allmailfrom' config file has any effect on older versions of nullmailer, and if not, we can just add the required variables to the role for now, perhaps with explanation that it works with nullmailer 1.4+.

Do you want to try and update the role?
