Why does Dovecot add \Seen flag for mails that have been RETRed? Does anyone really want to use this feature? I can't remember why I implemented it originally, perhaps it was just "because other servers do that too". I'm thinking about at least changing pop3_no_flag_updates=yes to be default.
Doesn't it just keep things looking consistent for a user if they happen to be using both a POP3 client and an IMAP client?
Sound implausible? Say for normal use they have a desktop configured that does POP3 (but doesn't DELE after RETR, obviously) but they are away from the desk and use a Web to Mail gateway which happens to be an IMAP client. It is presumably considered a nice feature that messages they last POPped show up as \Seen in the web interface and consequently stuff that has arrived since shows up as not \Seen. Maybe.
