Postfix on our cavendish server takes care of transferring mails in our infrastructure. The processes listed here are not relevant to the average FSFE user but for our System Hackers.
Creating an alias/forward
With a Postfix alias you can forward a mail sent to one email address to another address. For example, email@example.com always redirects to the @fsfe.org handle of the acting FSFE president and is not a usual FSFE supporter/volunteer account.
Log in on cavendish
Change or add a line to /etc/postfix/domains/fsfe.org or a virtual alias file of another existing domain
Run postalias /etc/postfix/domains/fsfe.org
Run postmap /etc/postfix/domains/fsfe.org
Now you can test it by sending a mail to the newly created alias. The changes should become effective immediately.
