Yes, you just met that "duplicate delivery suppression" feature of your 
Cyrus lmtpd. The duplicate  delivery database is purged every 3 days (see 
the appropriate process in your cyrus.conf). You can turn this suppression 
off if you want:

Put in your /etc/imapd.conf (or whereever you have your config fule):

duplicatesuppression: no
