Forwarded emails are unfortunately sometimes transmitted by Outlook as .eml files, which are unusable for normal users. In particular, extracting attachments from .eml files is a challenge.

What software can extract all attachments contained in a .eml file?

Requirements:

  • Free
  • Open source
  • Runs on Linux
  • Output a file per attachment, with the intended name.
  • No need to compile (binaries available, or script)
  • Reasonably fast to install, I would rather avoid having to set up a particular email client program just to process this .eml file.
  • I don't know the exact features of LookOut (Addon) for Thunderbird, but it gives in provides very good interoperability with the proprietary formats. You may try if this fixes it. – sebix Oct 27 '14 at 7:19
