Hi,
this might be a stupid question asked by someone who does not know enough about IMAP, but I'm going to tell you my user story anyway:
tl;dr: can I keep dovecot from moving all "NEW" message to· "OLD" state when the Mailbox was opened once and nothing actually read?
long version: My mail is delivered to a maildir on a machine I also have a shell account on. That Maildir is huge, it holds half a million messages. I usually access it directly with mutt accessing the spool. In the Mailbox, new messages automatically get the N flag and once I have opened it in mutt, I can mark it as "O" (old). I use that flag for messages that still need further work, I usually have a couple of hundred messages in that state. There is also a third state (I would call it "read") that doesnt display any flags in mutt.
Occasionally, I need access to an attachment directly on my work box. In the past, I have moved that message to a sub-maildir which I then access with Thunderbird or neomutt via IMAP and dovecot (configured via userdb).
I now want to give neomutt direct IMAP access to the BIG mailbox. I am impressed how quickly the neomutt/dovecot acesses this mailbox. However, once I have once opened that mailbox, all messages that had the N flag in the mutt-on-spool lose that flag immediately, replaced by the O flag. That destroys my method of seeing "O" messages as "needs work".
Since that happens with both Thunderbird and neomutt when testing, I suspect, this is either mandated by the protocol (which would be a showstopper for me), or a dovecot issue, maybe even a thing that I could configure in dovecot.
Hence, my question, can I configure dovecot to move a "NEW" message to "OLD" only if the message was actually READ/body-displayed by an IMAP client? And, if yes, how do I do that.
Greetings Marc
