With iRedMail, it's able to sign disclaimer on outgoing email with Amavisd-new
|
|
and alterMIME, it is pre-configured but disabled by default.
|
|
|
|
To enable the signing, please find setting in Amavisd config file `amavisd.conf`:
|
|
|
|
```
|
|
#$defang_maps_by_ccat{+CC_CATCHALL} = [ 'disclaimer' ];
|
|
```
|
|
|
|
Uncomment the `$defang_maps_by_ccat` line and restart Amavisd service will
|
|
enable signing disclaimer on outgoing email, default disclaimer text is stored
|
|
in `/etc/postfix/disclaimer/default.txt` (Linux/OpenBSD) or
|
|
`/usr/local/etc/postfix/disclaimer/default.txt`.
|
|
|
|
If you need a per-domain disclaimer, please update setting `@disclaimer_options_bysender_maps`
|
|
in Amavisd config file, add your domain name in correct syntax, then create
|
|
required file with disclaimer text. For example, for domain `example.com`:
|
|
|
|
|
|
```
|
|
@disclaimer_options_bysender_maps = ({
|
|
# domain 'example.com'
|
|
# disclaimer text file: /etc/postfix/disclaimer/example.com.txt
|
|
'example.com' => 'example.com',
|
|
|
|
# Catch-all disclaimer setting: /etc/postfix/disclaimer/default.txt
|
|
'.' => 'default',
|
|
},);
|
|
```
|
|
|
|
Restarting Amavisd service is required each time you changed its config file.
