Hi fegner.patricio
do you receive those emails from the admin email?
If so I resolve applying a filter. Right click on email address -> add to filter - > new filter
and under the voice perform the following action select what do you want to do ( I chose discard for example )

I hope this is what are you looking for.
Have a great time

There is a lot ways to preventing spam, some of them:

- Enabling antispam & antivirus service and Enhancing spamassassin spam filter.
- Enabling RBL check.i
- Check reverse DNS for incoming email.
- Use cloud spam provider.
