Most likely cause is either (a) a bug in lmtpd and it isn't cleaning up after itself or (b) lmtpd is crashing or (c) you're shutting down the server while it's in the middle of delivering a message.What are they, and how do you clean them out? I have stuff dating back to march 19th in there:Mar 19 2002 27181-1016554210 just delete, or is there somethign I should be fixing?
None of these are a particularly big deal. (b) would be the worst but you'd probably notice it if it was happening a lot.
You can just remove these; these should all be very transitory, so anything older than, say, an hour can be safely nuked.
