# Allow user to send email without smtp authentication
|
|
|
|
Create a plain text file: `/etc/postfix/accepted_unauth_senders`, list all
|
|
users' email addresses which are allowed to send email without smtp
|
|
authentication. We use user email address `user@example.com` for example:
|
|
|
|
```
|
|
user@example.com OK
|
|
```
|
|
|
|
Create hash db file with `postmap` command:
|
|
|
|
```
|
|
# postmap hash:/etc/postfix/accepted_unauth_senders
|
|
```
|
|
|
|
Modify Postfix config file `/etc/postfix/main.cf` to use this text file:
|
|
|
|
```
|
|
smtpd_sender_restrictions =
|
|
check_sender_access hash:/etc/postfix/accepted_unauth_senders,
|
|
[...OTHER RESTRICTIONS HERE...]
|
|
```
|
|
|
|
Restart/reload postfix to make it work:
|
|
|
|
```
|
|
# /etc/init.d/postfix restart
|
|
```
