Hi,
Moving mail files between Maildir mailboxes often confuses doveadm
sync: I end up with copies in both the original and new maildir.
Exact details and script to reproduce follow.
I can work around this by running doveadm move, but it does not fit well with
my workflow, which is based on paths to mail files (using mblaze as my mail
client).
Two questions:
1. Is there anything I can do to help dovecot notice the moves,
other than using doveadm move instead of just mv? I have tried
liberal use of force-resync but the problem is still there.
2. Is this a bug?
Details:
OS: OpenBSD current
$ dovecot --version
2.3.21.1 (d492236fa0)
config: My repro script below uses a one-line config, only setting
mail_location.
(An OpenBSD 7.5 server running Dovecot 2.3.21 is involved in my
real setup, but I was able to reproduce it locally without the
server involved.)
To reproduce:
(shell script follows)
- Make two maildirs "a" and "b", each with a subfolder ".Archive".
- Manually write a mail file to a/cur.
- doveadm sync
- force-resync everything
- manually move the file to a/.Archive/cur
- force-resync everything again
- doveadm sync
- Now the mail file appears four times: in a, a/.Archive, b, and b/.Archive.
Script to do the above follows my signature.
