I am also experiencing this problem. It's only Thunderbird that has problems renaming or deleting (certain) folders; other mail clients handle these operations just fine. I filed a bug against Thunderbird for this back in April but haven't yet had any response: https://bugzilla.mozilla.org/show_bug.cgi?id=1628600 Regards, Tristan -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tristan Miller Free Software developer, ferret herder, logologist https://logological.org/ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

I finally got around to this and thought I'd report on my experiences in case anyone else wants to do the same thing. From a Bash shell, I made a backup copy of the entire IMAP folder containing the messages with duplicate Message-ID headers. I then used "doveadm deduplicate" with the -m option to deduplicate the original folder. This didn't produce any logging output (even with -v), so from both the original and backup folders, I ran ls and redirected the output to a file, then used comm to find out which files had been deleted. I copied those files to a temporary directory and then rewrote the Message-ID headers as follows: for f in *; do sed -i -e 's/^Message-ID: https://www.dovecot.org/tools/maildir-size-fix.pl> Running this script threw an error about trying to pass "kill" a non-numeric argument, but it seemed to work anyway, and I was finally able to run "doveadm import".

Yeah, simply removing duplicates is pretty trivial, and any decent mail client will also have a nice way of doing this. The tricky part in my case is not removing the duplicates, but preserving them and giving them unique Message-IDs. If there's no existing way of automating this then I'll do as you suggest.

Non-destructive deduplication
Greetings.
I use Dovecot 2.2.29.1 as my IMAP server. Owing to a bug in my mail
client [1], several unique messages (mostly in my Sent folder) have
duplicate Message-ID headers. Dovecot itself doesn't seem to be
bothered by this, though my mail client is confused by the false
duplicates. (It screws up the threading display, and results in data
loss when I run the client's deduplication filter.)
I would like to change the Message-ID headers in the "duplicate" message
files stored in my IMAP server so that they are unique. I realize that
this has disadvantages of its own, but I can't think of a better
alternative.
So this leads me to two questions:
1) Will Dovecot get confused if I simply open the message files in a
text editor and manually change their Message-ID headers? If so, how
should I go about changing the Message-ID headers?
2) Does there exist any tool that will scan a maildir folder to find
messages with duplicate Message-IDs, and automatically rewrite the
Message-ID headers so that they are (probably) unique? I could
probably kludge together a quick shell script, but if someone's already
gone to the trouble of writing such a tool and making it relatively
robust, I'd rather use that instead.
Regards,
Tristan
