Supported Email file formats (IdClassification.Email - Email document (e.g., Outlook message (IPM.Note), EML, MIME mail, Lotus Notes .dxl, etc).)
- All entries in table below are supported for file format identification.
- 'X' in "Text" column indicates text extraction is supported for the file format.
- 'X**' in "Text" column indicates text extraction is supported BUT binary-to-text filtering is used on partially parsed document records.
- 'X' in "Metadata" column indicates metadata extraction is supported for the file format.
- 'X' in "EmbeddedItem" column indicates embedded item/attachment extraction is supported for the file format.
- 'X' in "ContentHash" column indicates a content hash is supported for the file format (see MD5ContentHash and SHA1ContentHash)
If a file format does not have a supported content extractor that extracts text then, optionally (default), a binary-to-text content extractor will be used to extract UTF-8, UTF-16, Windows-1252, and ASCII from the binary. In many cases, indexable text can be extract from unknown document formats.
