ytnef 2.6-1ubuntu0.1 (ia64 binary) in ubuntu intrepid

 Yerase's TNEF Stream Reader allows you to decode application/ms-tnef
 e-mail attachments, which are usually entitled "winmail.dat" and are
 generally a file container format that is only readable by Microsoft
 Outlook. Some TNEF streams also include RTF-formatted data.
 .
 ytnef parses these streams into normal MIME attachments and RTF
 attachments that you can read from non-Outlook mail readers.
 .
 A convenience script is provided to allow users to transparently
 filter messages containing TNEF attachments into messages with
 proper attachments, via procmail.
