<p>Hello,<br></p><p>I am trying to setup a shared mailbox for a small team. Let's say
Alice and Bob both need to read and answer <a href="mailto:sales@example.com">sales@example.com</a>. I would
like Alice and Bob to retain private \Seen flags on <a href="mailto:sales@example.com">sales@example.com</a>. I
know I can achieve that with INDEXPVT on shared or public mailboxes but
I am not 100% happy with this solution because:<br></p><p>- Thunderbird displays <a href="mailto:sales@example.com">sales@example.com</a>/Inbox and <a href="mailto:sales@example.com">sales@example.com</a>/Sent
as "subscribed folders" within <a href="mailto:alice@example.com">alice@example.com</a> and <a href="mailto:bob@example.com">bob@example.com</a>.
So Alice and Bob can't use the unified view of Thunderbird.<br></p><p>- I need create a special identity in Alice and Bob Thunderbird's
configuration so the sender is <a href="mailto:sales@example.com">sales@example.com</a> when Alice or Bob sends
an email from <a href="mailto:sales@example.com">sales@example.com</a> (and not <a href="mailto:alice@example.com">alice@example.com</a> or <a href="mailto:bob@example.com">bob@example.com</a>). But I am not sure another email client is able to do
that (on a mobile phone for example).<br></p><p>- I need to add ACL rights if a new folder is created under <a href="mailto:sales@example.com">sales@example.com</a>.<br></p><p>So I am now looking at the "master users" feature of Dovecot to
replicate this MS Exchange setup <a href="https://www.en.its.aau.dk/instructions/Mail/shared-mailbox-thunderbird/">https://www.en.its.aau.dk/instructions/Mail/shared-mailbox-thunderbird/</a> (<a href="mailto:alice@example.com">alice@example.com</a> and <a href="mailto:bob@example.com">bob@example.com</a> log is as <a href="mailto:sales@example.com">sales@example.com</a>). I
achieved that but I don't know how to retain private \Seen flags so that
Bob doesn't see an email as read even if Alice has marked it as read
before.<br></p><p><b>Is it possible to retain private \Seen flags with master users? If yes, how can I achieve that?</b><br></p><p>Thank you for any help!<br></p><p>PS: I posted the same question on <a href="https://forum.iredmail.org/post77816.html">https://forum.iredmail.org/post77816.html</a> and <a href="https://forum.iredmail.org/topic13549-proposal-for-a-exchange-like-shared-mailbox-aka-login-as.html">https://forum.iredmail.org/topic13549-proposal-for-a-exchange-like-shared-mailbox-aka-login-as.html</a> but I couldn't get help and was advised to ask here.<br></p><div><br></div>
