### Send-Only Aliases
Sometimes, it may be useful to allow certain accounts to send as other accounts, even when [the `SPOOF_PROTECTION` environment variable is enabled][spoof-protection]. This may be used to allow services to send accounts as other addresses without needing to disable spoof protection entirely, and without affecting incoming mail (which traditional [aliases](#aliases) would do).
To configure these aliases, add them to `docker-data/dms/config/postfix-regexp-send-only.cf` in the same format as [the other regexp aliases](#configuring-regexp-aliases). For example:
```cf
/^.*@example.com$/ admin@example.com
/^.*$/ superadmin@example.com
```
In this example, `admin@example.com` would be able to send as any address at `example.com` and `superadmin@example.com` would be able to send as any address at any domain.
