[Dovecot] purge maildir folder after sa-learn

[Florian Effenberger]

Hello,

I am looking for a command-line utility to automatically purge one
Maildir folder. I want to periodically run sa-learn from cron, and
after the spam learning folder has been added to the Bayes database,
its contents should be deleted. I've searched a bit, but only found a
few old utilities or some telnet+expect scripts, which both didn't
look too reliable.

Is there any command-line utility to delete all contents of a Maildir
folder, or is there any other solution?

Thanks,
Florian
