Static master user

Random master usernames and passwords are automatically created on every restart of dovecot-mailcow.

That's recommended and should not be changed.

If you need the user to be static anyway, please specify two variables in mailcow.conf.

Both parameters must not be empty!

DOVECOT_MASTER_USER=mymasteruser
DOVECOT_MASTER_PASS=mysecretpass

Run the command below to apply your changes:

docker compose (Plugin)docker-compose (Standalone)

docker compose up -d

docker-compose up -d

The static master username will be expanded to DOVECOT_MASTER_USER@mailcow.local.

To login as test@example.org this would equal to test@example.org*mymasteruser@mailcow.local with the specified password above.

A login to SOGo is not possible with this username. A click-to-login function for SOGo is available for admins as described here No master user is required.
