The mail server automatically evaluates incoming e-mails for possible spam characteristics.
Global filter rules can be used to control how e-mails should be handled.
Global rules apply to all devices and allow filtering even on e-mail clients that do not include their own spam protection features.
Note: The step-by-step guide represents an example configuration.
1. Filter using Subject Rewrite ***SPAM***
- Log in to Webmail and click Settings -> Filters
- Click Create:
- Filter name:
***SPAM*** - Filter enabled: yes
- Scope: matches any of the following rules
- Subject -> contains ->
***SPAM*** - Move message to: Spam
- Save
2. Filter using invisible headers
- Log in to Webmail and click Settings -> Filters
- Click Create:
- Filter name: X-Spam: Yes
- Filter enabled: yes
- Scope: matches any of the following rules
- String -> X-Spam -> contains -> Yes
- Move message to: Spam
- Save
3. Manually filter recurring spam
- Log in to Webmail and click Settings -> Filters
- Click Create:
- Filter name: SPAM Strings -> Spam
- Filter enabled: yes
- Scope: matches any of the following rules
- From: unwanted sender
- Subject: unwanted subject
- Move message to: Spam
- Save
Be careful when filtering text strings within the message body.
4. Manually filter recurring unwanted e-mails
This may include recurring notifications or advertising e-mails that are not technically spam, but should still not appear in the inbox.
Such e-mails should not be marked as spam, but instead sorted automatically — for example into a subfolder or directly into the trash.
- Log in to Webmail and click Settings -> Filters
- Click Create:
- Filter name: SPAMMY Strings -> Trash
- Filter enabled: yes
- Scope: matches any of the following rules
- Subject: e.g.
website was created with wordpress,relisting is very easy - Move message to: Trash
- Save
Be careful when filtering text strings within the message body.
Additional notes
In the Control Panel you can switch to “custom spam ratings” within the advanced settings and adjust the spam score threshold individually if you do not want to follow the default mail server values.
