No, they mean "lock".

If you're using a Maildir format, they aren't necessary -- you only have a single message per file, and the file itself is moved. However, if you're using an mbox format, where there are many messages per file, you'll want lockfiles to protect your data and prevent collisions (where multiple operations are trying to make changes to the file simultaneously). -- Matthew Weier O'Phinney -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
