Configuring Filters

G DATA Web Portal Malware & Spam Filter Settings

Remember to save all changes using the button in the upper-right corner of the window. Toggle states and entered values take effect only after you save.

All whitelist entries cause emails, attachments, or included URLs to bypass scanning by G DATA Mail Protection. Be aware that this creates security risks.

You can create whitelist entries for URLs and MIME types directly from quarantine.

Sender Filter

Enable this filter if you want specific sender email addresses to bypass malware scanning (whitelist) or if you want emails from specific senders always to be moved to quarantine (blacklist).

Add senders to the whitelist only as justified Exclusions. Simply knowing the sender of an email or a particular website does not establish that a Detection is a false positive. It is always possible that email senders or website operators have themselves become victims of a virus outbreak and are unknowingly spreading the infection. If in doubt, have the Detection reviewed by us!

You can enter whitelist and blacklist entries directly in the designated field.

Use the following syntax:

[Email address] = only this specific sender
*@domäne.de = All senders sending from this domain.

Place each entry on a separate line.

If you already have an exported list of entries separated by a delimiter, click + Import entries. Copy the contents into the upper field and specify the delimiter used. You will then see a preview of the separated entries as they will appear after import. Review all entries for accuracy here. Click the Import button to import the list.

Be aware that the whitelist or blacklist entries you create yourself do not constitute a professional spam filter. Professional spam filtering is already provided when you enable our spam function. You do not need to add every email that was not detected as spam to these lists. The likelihood of receiving another email from the same sender is low because the sender names used in spam attacks constantly change. Persistent newsletters that cannot be unsubscribed from, however, can be useful candidates for blacklist entries.

URL Filter and Spam Filtering

Here you can enable or disable scanning of URLs contained in emails and configure Exclusions. Whitelist entries are not scanned. Emails containing blacklisted URLs are moved immediately to quarantine without being scanned.

Add URLs to the whitelist only as justified Exclusions. Simply knowing the sender of an email or a particular website does not establish that a Detection is a false positive. It is always possible that email senders or website operators have themselves become victims of a virus outbreak and are unknowingly spreading the infection. If in doubt, have the Detection reviewed by us!

If you disable the URL filter, URLs are no longer scanned at all. Spam filtering is then also disabled because URL scanning is an essential component of spam Detection.

Be aware that the whitelist or blacklist entries you create yourself do not constitute a professional spam filter. Professional spam filtering is already provided when you enable our spam function. You do not need to add every email that was not detected as spam here or in the sender filter. The likelihood of receiving another email from the same sender is low because the sender names used in spam attacks constantly change. Persistent newsletters that cannot be unsubscribed from, however, can be useful candidates for blacklist entries.

Whitelist entries should also be carefully considered. Sender addresses you recognize can be used by spammers. Those spam emails would then bypass filtering. However, it can make sense to whitelist the sender of a newsletter you want to receive that is correctly detected as bulk email.

You can enter whitelist and blacklist entries directly in the designated field.

Use the following syntax:

www.domäne.de = only the main domain
*.domäne.de = the domain, including all subdomains
domäne.de/ = only specific domain pages

Place each entry on a separate line.

File Filter

Here you can enable or disable scanning of email attachments and configure Exclusions. If you disable this function, no files are scanned.

When file scanning is enabled, you can filter email attachments based on MIME identification of files and, depending on the file type, either accept them without scanning (whitelist) or immediately move the email and its attachment to quarantine (blacklist).

You can also set a size limit for email attachments here. Attachments larger than the value you enter are not delivered to the recipient but are initially moved to quarantine. Set the value to 0 for no size limit.

You can find syntax for creating MIME type whitelist entries at the following site, among other resources: https://mimetype.io/all-types

Place each entry on a separate line.
