Hi, I'm using courier-imap as the mailserver of the domain, this is OK for several years, thanks courier! :-)
I have one "weird" need at work... to have some documents that are received by e-mail available to a group of people, and prevent them to be erased. So, I have one idea: - create a mail account "[email protected]" - make some smtp/procmail filter to "write them to disk" using an imap maildir directory structure - the files and directories of this maildir structure would be read+write by the user that delivers (probably some procmail setuid script will deliver) - the files and directories of this maildir structure would be readonly by the user that reads the mail (imap) Then I configure the mail client of the group of persons that need access to this documents and they would only be allowed to read the email. Not allowed to do things like this: move folders, delete, mark as read, ... I did some test by changing a current user maildir folders to chmod 555 and the files to chmod 444, however, the courier-imap server gives an error when the folders/files are readonly. I need hists about: - is my idea too weird, any other method of acessing mails without permission to change/delete things? - any workaround to make courier-imap work well with read-only folders/files? - any workaround could be done to make courier-imap prevent changes to mails (just for some users, not for all users of the domain)?
