Insert these lines to `data/conf/postfix/main.cf`. "relayhost" does already exist (empty), just change its value.
|
||
|
|
```
|
||
|
|
relayhost = [your-relayhost]:587
|
||
|
|
smtp_sasl_password_maps = hash:/opt/postfix/conf/smarthost_passwd
|
||
|
|
smtp_sasl_auth_enable = yes
|
||
|
|
```
|
||
|
|
|
||
|
|
Create the credentials file:
|
||
|
|
```
|
||
|
|
echo "your-relayhost username:password" > data/conf/postfix/smarthost_passwd
|
||
|
|
```
|
||
|
|
|
||
|
|
Run:
|
||
|
|
```
|
||
|
|
docker-compose exec postfix-mailcow postmap /opt/postfix/conf/smarthost_passwd
|
||
|
|
docker-compose exec postfix-mailcow chown root:postfix /opt/postfix/conf/smarthost_passwd /opt/postfix/conf/smarthost_passwd.db

docker-compose exec postfix-mailcow chmod 660 /opt/postfix/conf/smarthost_passwd /opt/postfix/conf/smarthost_passwd.db
|
||
|
