"seen" flag for multiple users // cyrus and procmail

[Kristian Rink]

Hello all,...

...being pretty new to imap, I am running cyrus on top of several
Debian woody machines inside some small / mid-range company 
networks. By now, I am quite happy about cyrus, procmail and 
postfix handling mail on my servers, still there are (right now) two
things I couldn't get along with, so far:

(a) in this network, IMAP is used because the vast majority of 
mail traffic needs to be seen not only by a single user but by a
group of persons. For what I have experienced and also read in
the archive of this list, it is not possible in cyrus (in IMAP?) to have
a general "seen" flag for mails or mailboxes so this way it is 
impossible for any user who is able to read mail in the shared 
mailboxes to find out whether or not anyone else already has read
and possibly answered new mail. Is there a way to work around 
this condition? Reading the cyrus man pages I hoped that the "s" 
ACL setting would be doing right what I need here but obviously
it didn't work.

(b) On my machine, procmail is used to sort mails. In some situ-
ations mail needs to be delivered to more than just one mailbox,
so I tried to use procmail filtering recipes like that:

:0 c
* ^TOwhoever
| $DELIVER_TO_ANOTHER_MAILBOX

The ":0 c" is working well while delivering mail to mail folders but
it doesn't work while using cyrdeliver to put mails into IMAP mail
boxes. _Is_ it possible to make some procmail configuration like
this work with cyrus?

TIA, have a nice evening everyone...
Cheers,
Kris
