I'm having similar problems (and have, off and on, for a long time,
including with other mail servers).

In my case, yes. I mean both. ;-)

I recently got a set of duplicate emails (including this one). I did
have some connectivity problems late last night, and this I saw in
the log file:
Dec 1 10:42:04 stove dovecot: [ID 107833 mail.info] IMAP(kamath):
Disconnected for inactivity
Dec 1 10:42:07 stove dovecot: [ID 107833 mail.error] IMAP(kamath): X-
IMAPbase uid-last unexpectedly lost in mbox file /var/mail/kamath
