OK. That may be more complexity than I need for my situation. So please bear with me as I try to understand this. IF: Postfix is already configured to deliver mail destined for the virtual domain "domain.com" to Dovecot --and-- I create the NAMESPACE and NAME setup as you described --and-- I create a Dovecot userdb entry for n...@domain.com (but no passdb entry) --and-- I configure ACLs so that all domain.com users can read NAME's mailbox but only admin users can delete messages in NAME's mailbox --and-- I configure the virtual INBOX for POP users to include "RealMails" and "NAME" THEN, I'm thinking that: Because there is no passdb entry, user n...@domain.com cannot log in --and-- Because userdb defines NAME's home directory, incoming mail to n...@domain.com would be delivered to the NAME mailbox, just like any other user in domain.com, without the need for aliasing or sieve --and-- Because of the ACLs, IMAP admin users would be able to delete/manage NAME's messages and everyone else would be able to read NAME's messages --and-- Because of the virtual INBOX, POP users would be able to read the NAME messages. Does that make sense? Am I missing something? > Its necessary to overlook the whole process chain to properly configure > everything. Yes! Agreed!

Re: shared/public mailbox application
Basically we alias n...@domain.com to dove...@domain.com. doveadm@ has a sieve-Script which files into the public folder. You could also configure a postfix transport which does the job. Its necessary to overlook the whole process chain to properly configure everything. And a lot of try out :) On 29 Nov 2016, at 6:34, Michael Fox wrote: > Thanks Tobias.

RE: shared/public mailbox application
Thanks Tobias. Thanks for the detailed reply. I think I see what you’re doing. But I’m unclear on something (since I’m a nube): Can anyone send mail to n...@domain.com <mailto:n...@domain.com> and have it appear in the public mailbox? If not, would it be enough to create a userdb entry which defines a pseudo-user NAME, including its home directory, such that imcoming mail addressed to n...@domain.com <mailto:n...@domain.com> could be delivered into that mailbox?

Thanks much, Michael 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. | | | ...INBOX | | .Drafts (folder) | | .Trash (folder | | ... | | ~.Shared AAA --> ../aaa | | ~.Shared BBB --> ../bbb | | | ...INBOX | | ... | | ~.Shared AAA --> ../aaa | | ~.Shared BBB --> ../bbb | | | ...INBOX | | ... | | | ...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. If you're not using Linux I cannot help. Adrian
Re: shared/public mailbox application
Hi Michael, we migrated from Cyrus Shared Folders to Dovecot Public Folder. Our setup with Dovecot: - Public Namespace type=public - prefix=NAMESPACE - location=maildir:/var/vmail/public/domain.com/folder:INDEXPVT=~/public/domain.com/NAME - list=children to show NAMESPACE only if acl is given - Restart Dovecot - cd /var/vmail/public/domain.com/NAMESPACE - mkdir .NAME - We utilise one user dove...@domain.com to control acl - doveadm acl set -u dove...@domain.com NAMESPACE/NAME user=dove...@domain.com all (this creates also the Maildir) - doveadm mailbox subscribe -u dove...@domain.com NAMESPACE/NAME - dm acl set -u dove...@domain.com NAMESPACE/NAME user=firstname.lastn...@domain.com lookup read write write-seen write-deleted insert post expunge User firstname.lastn...@domain.com can now subscribe to the public folder „NAMESPACE/NAME“. With this base you could create a more specific setup which more precisely fits your need. There are also other strategies achieving Shared Folders the Cyrus way. :) Hope that helps.
