Please be advised that support for .doc (application/msword) will stop immediately on Phaxio due to possible security vulnerabilities. The file type .doc is a legacy MIME type to the newer .docx and support is ending for this file extension by Microsoft in October 2025. In addition, we are removing support for .odt (application/vnd.oasis.opendocument.text) immediately due to overall security concerns and known exploits with that file type. You can find the support file types here: https://www.phaxio.com/faq#11 Please do not reply to this email as it is unmonitored. Please reach out to [email protected] with questions or concerns. Thank you, Phaxio Support
