## New guide
|
|
|
|
Edit a mailbox and select "Allow to send as *".
|
|
|
|
For historical reasons we kept the old and deprecated guide below:

## Deprecated guide (DO NOT USE ON NEWER MAILCOWS!)
|
|
|
|
This option is not best-practice and should only be implemented when there is no other option available to achieve whatever you are trying to do.
|
|
|
|
Simply create a file `data/conf/postfix/check_sasl_access` and enter the following content. This user must exist in your installation and needs to authenticate before sending mail.
|
|
```
|
|
user-to-allow-everything@example.com OK
|
|
```
|
|
|
|
Open `data/conf/postfix/main.cf` and find `smtpd_sender_restrictions`. Prepend `check_sasl_access hash:/opt/postfix/conf/check_sasl_access` like this:
|
|
```
|
|
smtpd_sender_restrictions = check_sasl_access hash:/opt/postfix/conf/check_sasl_access reject_authenticated_sender_login_mismatch [...]
|
|
```
|
|
|
|
Run postmap on check_sasl_access:
|
|
|
|
```
|
|
docker-compose exec postfix-mailcow postmap /opt/postfix/conf/check_sasl_access
|
|
```
|
|
|
|
Restart the Postfix container.
