[Users] Winmail.dat crashing Claws-mail

[Liz]

Someone (sadly) forwarded me a mail with a winmail.dat attachment. It's
too private to forward to anyone to do forensic examination, but Claws
segfaults every time it tries to get this mail off my server.

I've got it quarantined so I can use my mail client.

I actually need to save this email.
Has someone any special system they can recommend for stripping the
attachment off the mail while it's still on my mailserver (squirrelmail
access)?
