OMiC: A plugin to extract winmail.dat files
Sooner or later, all Mail.app users who have any kind of email communication with Outlook users will get a message containing the dreaded unopenable winmail.dat file.
TNEF
is a utility that extracts the files buried inside. It can really save your bacon.
Now a developer has wrapped the utility into a mail.app bundle which automatically recognises incoming emails with winmail.dat attachments.
When they arrive, it either opens iCal if the embedded file is an Outlook appointment or prompts you to save the embedded files in a folder of your choice:

I don’t get enough email from Outlook users to need it. Firing up TNEF’s Enough app on the odd occasion is all I need.
If you get a lot of this kind of email, the plugin takes out some extra steps and might be worth the shareware price.
OMiC is shareware (5 euros = USD 6.30) and is available from the developer’s web site
. He hopes to make some money from the plugin for his compulsory military service, which begins soon.

OMiC is what I need as I always get those pesky winmail.dat files. However, it costs 10 euros now and it does not support Leopard.

There is a Leopard beta that I am running now without problem. I’m guessing that a Leopard release is not far away.
