Dovecot errors when creating a filter rule to forward an email
What happened and when does this occur?
Logwatch reports the following (sanitized) error:
imap(<EMAIL_ADDRESS>)<1492788><5ivHyk/6QQSsOq3S>: Error: stat(/var/mail///.dovecot.lda-dupes/tmp) failed: Not a directory: 2 Time(s)
What did you expect to happen?
Clean log files in logwatch
How do we replicate the issue?
1.Using Roundcube I created a rule to forward specific emails from one local mail user to another mail user (error seems to have started when I did this)
2. This creates a file named .dovecot.lda-dupes in the users maildir folder
3. Dovecot appears to think this is an email folder because of it's location and because it starts with a dot

According to this post the location of this file is an issue:
https://dovecot.dovecot.narkive.com/BRuWMv1g/problem-with-lda-dupes-file
Because it starts with a dot and is located where your Maildir-root
directory is and the IMAP demon tries to access a mailbox called
"dovecot.lda-dupes".
You should not (must not) have home == maildir root.
