Less spam received (checklist)
1. If you receive a lot of unwanted spam that is not marked in the subject with [SPAM], you can raise the filter level in the https://ac.managedomain.nl/ With the spam filter on Extended, messages are more likely to be spam than on Standard.
2. In addition, we strongly recommend that you disable the catch-all function (so that all e-mail addressed to your domain arrives in the specified e-mail box). This will reduce spam.
3. Place your e-mail address as little as possible on public websites. It is better to make an image of the text with your e-mail address, or to replace the "@" sign with "at". As a result, e-mail address harvesters are less likely to get your e-mail address.
4. Do not respond to spam messages, and do not click on links from a spam message. If you do that, you will know that your e-mail address will be read.
