About:
Mpack is a command-line utility for encoding binary files into MIME-compliant email messages and decoding them back to their original form. It supports multipart MIME structures, allowing for the transmission of attachments via email protocols. The tool is particularly useful for automating mail processing on systems without full mail user agents.
Key Features:
  • Encodes binary files into MIME format
  • Decodes MIME messages back to binary files
  • Supports multipart messages for multiple attachments
  • Command-line interface for scripting and automation
Use Cases:
  • Sending binary files as email attachments from scripts
  • Decoding incoming email attachments on mail servers
  • Automating file transfers via email protocols
Alternatives:
  • mutt – Full-featured email client with attachment support, but heavier dependency
  • uuencode – Legacy encoding tool, but lacks modern MIME support
