Add a Always BCC field for the mail server

stephdl commented 1 month ago

Proposed solution

In some configuration or to use some mail archiver we need to forward all received or sent emails. This feature exists in postfix but it is hidden, we use the environment variable : POSTFIX_ALWAYS_BCC My idea is to create the user interface to manage this environment variable

Alternative solutions

Do nothing, but now with the Piler module which is coming, we use this environment variable and the sysadmin must be aware that the Bcc is enabled

QA

case 1 install mail from ghcr.io/nethserver/mail:1.4.2-dev.1 go to mail > settings > relay you have a new toggle with an input field Always BCC Enable the toggle and write an email address, press save the environment variable POSTFIX_ALWAYS_BCC is added with the email address and postfix is reloaded Disable the toggle and press save, the variable POSTFIX_ALWAYS_BCC is set to empty and postfix is reloaded

This bug is only the UI verification of the actions get-always-bcc and set-always-bcc

case 2 set up a ns7 mail server and in the settings area of nethserver-mail set the always BCC Address field to a mail address Install nethserver-ns8-migration write in /usr/share/nethesis/nethserver-ns8-migration/apps/nethserver-mail/bind.env that you will use the MODULE_IMAGE_URL="ghcr.io/nethserver/mail:1.4.2-dev.2" migrate the mail server to NS8 at the end of the migration, the NS8-mail is up with the mail > settings > relay > Always BCC not empty and enabled
