duplicate checking is eliminating all (most of?) my messages

[Ross Boylan]

[list/webmaster: please see the P.S. below]

It appears that cyrus is treating all messages as duplicates, even ones
that it has not seen.  So I'm not getting any mail.  Can anyone help?

I'm on Debian running cyrus21-imapd  2.1.18-1.  Messages are being
delivered over lmtp via exim4, and I have a local .sieve filter in
place.  The messages are being delivered in big groups, as I am pulling
them in from a server.
So: IMAP server (not cyrus) -> fetchmail in batches of 10
-> exim4 -> cyrus via lmtp
exim runs the message through a spamassassins spamd demon on receipt,
i.e., before delivery to cyrus.

My mail is a mess because of some network changes, and I have been
running repeated tests, which have caused many legitimate duplicate mail
eliminations.  This new behavior (treating everything, or nearly
everything, as a duplicate) seems to have kicked in during a delivery of
200 messages, the first 10-20 of which were probably legitimate
duplicates.

I have since sent a single test message; it went through OK.

P.S. The wiki directed me to a majordomo list; it would be good if
somebody updated

Typical log entry.
