reconstruct: odd behaviour with delayed expunge (2.3.9)

[Matt Bernstein]

Hi,

I've been having the same glibc-vs-lmtpd problems as Ali Nebi (though I'm 
using Exim), also on FC6 x86_64, but I noticed that at least in most cases 
I could get the mail delivered after reconstructing the users' mailboxes.

My man page for reconstruct says that the "-k" option means "Preserve the 
cyrus.expunge file and the corresponding message files instead of deleting 
them."

Unfortunately, "-k" not only preserves them, it unexpunges and undeletes 
the messages, with a few bonus messages in my INBOX along the lines of 
"This morning I seem to have about 7000 resurrected emails in my inbox" 
from people like my Head of Department.

Luckily, re-running reconstruct without "-k" makes them go away, 
permanently, and presents me with new bonus messages along the lines of 
"Thank goodness" from the same sort of people.

So.. I think there's a bug in the "-k" bit, I've lost the ability to 
unexpunge old messages (which I know is a perk of delayed expunge rather 
than its /raison d'être/), and I thought I'd relate my moderately scary 
experience to those who might fall into a similar trap. :-)
