Hi, I did that in Linux (Ubuntu) by using symbolic links. In the INBOX of users that you want to see shared emails place a symlink to the shared INBOX. <domain> | <user 1> | | ...INBOX | | .Drafts (folder) | | .Trash (folder | | ... | | ~.Shared AAA --> ../aaa | | ~.Shared BBB --> ../bbb | <user 2> | | ...INBOX | | ... | | ~.Shared AAA --> ../aaa | | ~.Shared BBB --> ../bbb | <aaa> | | ...INBOX | | ... | <bbb> | | ...INBOX | | ... The only thing that could create problems are permissions. I use the same UID/GID for all users (vmail:vmail) so I don't have such problems. If you want special permissions for groups of users (some can delete emails in shared folders) you need to define the permission groups, add users you want to those groups and set rw permission and set group bit on shared folders.
Thanks Adrian. That's an interesting idea. I don't think it will fit what I'm trying to do. But thanks for taking the time to respond. Every little bit helps me learn how things work.
