Restrict attachment uploads to an allowlist of MIME types

Attachment MIME Type Restriction

This module restricts attachment uploads to an explicit allowlist of MIME types using content-based detection rather than filename extensions. Only configured MIME types are accepted; everything else is rejected. Leaving the allowlist empty disables the restriction and allows all file types.

For incoming emails, the email itself is always accepted, but any attachments whose MIME type is not in the allowlist are stripped out before the message is saved. A security notice is then posted on the related record listing the removed files, so users can see what was filtered.
