Re: questions for users of shared mailboxes: conversations

Hello,

We are an university with two cyrus architectures :
    students : 10 backends with quota, murder, 100k users, no shared
    employee : 18 backends, no quota, murder, 4000 users, some shared.

Quoting Ricardo Signes via Info <[email protected]>:

Our conf :
    conversations: 1
    conversations_db: twoskip

Conversation is needed for xapian search.

50 shared mailboxes on the employee server, mostly for staffs, each  
read by some 10 users.

We would like there to be better integration of shared mailboxes with  
Murder. All users of our shared mailboxes need to be on the same server.
