Hello,
When using a sieve, there is no problem with duplicates, but it is
impossible to transfer all users to a sieve.

Hello,
I migrated our mail infrastructure to Dovecot on Ubuntu 18.04 some
months ago. It works fine, but recently some users told me that
they sometime receive duplicated emails. Same email content, same
headers including message-id.
I'm using two dovecot servers on two sites. Both server are in
cluster. We don't use shared folders. All users that reported this
issue so far are using the same server instance. The problematic
emails are coming from local users on that instance too. The
examples they given to me was emails with many recipients (To/CC).
A specific message can be received twice (or more) by recipient A
but only once by recipient B. I didn't see anything in the logs
about sieve rules that redirect emails to others recipients.
Where should I look to diagnostic this issue?
Hello,
Thanks for your hints. The message from Битус Павел in another thread
today seem to be similar to my problem. I asked my users if the
affected messages are processed by a local rules in Thunderbird and
they said yes. I asked them to replaces theirs local rules by sieve
rules instead. We'll see if it fixes the problem.
Thanks!
