Hi, i use Yarn 092 under DOS/W95 and i like to filter/file mailmessages
AFTERwards instead of direct when importing them.

I thought Yarnutil 0.4 with selfold would do the trick but it complains
about my INBOX being corrupt.

Can anybody give me advise on how to Filter mail messages (or news)
afterwards ??

Thanx a lot!

Ray
