How does singleinstancestore figure out messages that can be hard linked? It doesn't seem to do it by message-id across mailboxes. If I send email to a mailman list with all my users, that mail goes into their mailboxes individually (not hard linked as a single instance) even though the message-id on each is definitely the same.
I am not sure how mailman does sending. I guess it might make a seperate connection to the SMTP server for each user meaning that each RCPT TO is for one user. If singleinstancestore keys on the RCPT TO envelope, then I guess the usefulness of singleinstancestore will be rare. Also, I am using sendmail which calls procmail for the MDA which in turn calls the deliver program for actually delivery. So it is definitely true that deliver is called separately for each user no matter how the mail comes into sendmail. --- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
