Can master users retain private \Seen flags ?

[tuuialou]

Hello and thank you for your answer.

I know https://wiki.dovecot.org/SharedMailboxes/Shared and I successfully implemented it but I am not 100% happy for the 3x reasons described in my original message.

I understand the "exchange-like" solution described at https://forum.iredmail.org/topic13549-proposal-for-a-exchange-like-shared-mailbox-aka-login-as.html leverages the master user feature of Dovecot to reach my goal (retain private \Seen flag without using the Shared mailbox feature). Or am I missing something??

Basically, my question is:

Is it possible to retain private \Seen flags between sales at example.com*alice at example.com and sales at example.com*bob at example.com?

Thanks again for your help!

I would like Alice and Bob to retain private \Seen flags on sales at example.com. I know I can achieve that with INDEXPVT on shared or public mailboxes but I am not 100% happy with this solution because:

But I am not sure another email client is able to do that (on a mobile phone for example).

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.
