We could add a X-SHAREDSEEN capability, letting clients know that the
server has the functionality, but its still a per-mailbox option.

Okay, I just wanted to point it out.
but I wouldn't recommend trying to use any free-form banner information to
determine a server's capability. In fact, some Cyrus servers might not
even include "Cyrus" in the banner if folks turn the "serverinfo" option
off.
I know this is suboptimal, but still some clients might still do it.
The proper way to detect the presence of shared seen state is the
following (don't forget that shared seen state is per-mailbox):
Check for ANNOTATEMORE in the CAPABILITIES
If not present, then no shared seen state.
Otherwise,
GETANNOTATION <mboxname> "/vendor/cmu/cyrus-imapd/sharedseen" "value"
If you get an empty response, then no shared seen state. Otherwise, the
value will tell you if its enabled on the given mailbox.
This would answer the wrong question, we want to detect if the server is able
to run in shared seen state. if it does we can offer a configuration option,
otherwise we do not.
I do not know if there is a different test method that could answer this
question. It is not feasable to try to set the annotation on a test folder
for each connection IMO. So best would be if there would be a SHAREDSEEN
or so capability.

.diff?r1=1.545;r2=1.547;f=h The log message indicate no rational of this
change, is it indentional?
(The second commit fixed a typo that "POP3" was in there, so it does look
like a typo indeed.)
Ken, both commits are from you. :)
I detected this change because we wanted to detect if there is the
ability to have shared seen flags in KDE Kontact enterprise and our regex
contained "IMAP4", thus we've noticed the change.
We'll change the regex, this kind of change should not happen without a
reason I guess.
(Even better would be to have a capability or so or a better way of
detecting the existance of the shared seen flags annotation switch. :) )
Best Regards,
Bernhard
