Attachment rejection

Attachments filed may be rejected by the Creatio system as it checks the file contents correspond to the file extension.

Various messages like "The extension of the file does not correspond to the file type signature" and "The [html] file extension is forbidden by security settings. If you need to work with such files, please contact your system administrator to remove the extension from the [File extensions DenyList] (FileExtensionsDenyList) system setting" may be seen.

An example of a file that might show this when opened in excel

so ideally users should verify files before trying to save the email to Creatio.
