Preconfigured content filter sets
Here you will find a tabular overview of the content filter sets preconfigured in NoSpamProxy Cloud as well as their respective settings.
NOTE: Note the differences between Office files despite the same file extensions. For example, regular Word documents and Word documents with OLE objects both have the file extension DOCX, so that different entries can apply in the content filter.

Inbound emails with sandboxing
NOTE: The content filter settings Medium - Sandboxing and Strict - Sandboxing are available if you have purchased a licence for the NoSpamProxy Sandbox Service. The Sandbox Service increases the likelihood that harmful content will be detected.
Important notes
NOTE:
- The content filter Wildcard allows all inbound emails to pass and should only be used in special cases.
- NoSpamProxy processes emails whose size does not exceed 500 MB.
- Files stored on the Web Portal are automatically deleted after four weeks. If in doubt, download any files you may need.
- We recommend that you select the setting Strict for both inbound and outbound emails.
- If there are non-allowed file types inside allowed archives such as ZIP, 7ZIP or GZIP, the entire archive is handled according to the configuration for the file type. Thus, if an email contains an (allowed) ZIP-compressed file, it will be rejected if the ZIP archive contains, for example, a (non-allowed) executable file.
