Summary: EXPUNGE and multiple sessions breaks IMAP protocol
Description:
Using MySQL as backend if it matters.
I open two IMAP sessions to the same mailbox and execute commands:
Session 1:
x append inbox {10}
+ OK gimme that string
From: foo
x OK APPEND completed
x store 1 +flags \deleted
* 1 FETCH (FLAGS (\Seen \Answered \Deleted \Draft))
x OK STORE completed
x expunge
* 1 RECENT
* 1 EXPUNGE
x OK EXPUNGE completed
x fetch * uid
* 16 FETCH (UID 414)
x OK FETCH completed
Sesssion 2:
x noop
* 0 RECENT
* 1 EXPUNGE
* 15 FETCH (FLAGS ())
* 16 FETCH (FLAGS ())
x OK NOOP completed
The session 2 saw 16 messages originally. It should have given "* 16
EXISTS" reply after the EXPUNGE.

OK, I misread section 5.2 in rfc3501. Fixed in svn.

SVN didn't compile with me, I guess you meant <= instead of =< ?
But now I don't see any EXISTS replies at all, ever.

Quite right.
The fact that no EXISTS responses are ever sent during EXPUNGE responses
is to accomodate client bugs (Mail.app <2.1, and Outlook) that experience
synchronization problems if EXISTS/RECENT are sent in reply to commands
other that NOOP or CHECK.
This behaviour was noted by the docecot team, and confirmed by dbmail
users as well (though only anecdotally). Do you have additional
information? I don't like having to cater to magical clients quirks rather
than the RFC, but outlook compatibility is a hard requirement.
I'm open to suggestions here. I'm downscaling the severity of this report
for now.
