I've been seeing the following wonky behavior with Dovecot. Currently
this is with Dovecot 2.0.19, but I was also seeing it in earlier
versions as well, including versions from the 1.x series. Some
background, this is from Horde's ActiveSync library, when it is trying
to determine what UIDs have recently been expunged. I can guarantee
that when this command was sent, there was only one or two emails that
were removed since the provided MODSEQ value.

Also, to verify it wasn't something screwy with my server, Michael
Slusarz provided me with this from his server:
<quote> There's definitely something wonky going on in the code. There's a certain tipping point of modseqs where the values become incorrect. For a mailbox with HIGHESTMODSEQ of 54004, I see this:
a uid fetch 1:* UID (VANISHED CHANGEDSINCE 53881)
- VANISHED (EARLIER) 1:37308,37310:40788,40791:41032,41034:41083 a OK Fetch completed. b uid fetch 1:* UID (VANISHED CHANGEDSINCE 53882)
- VANISHED (EARLIER) 41029:41030,41047:41083 b OK Fetch completed. </quote>
Thanks for any guidance.
