I have update today dovecot and dovecot pigeonhole to the latest version available on my centos 7.
It’s a small email servers with postfix/amavisd/clamav/spamasssin.
I had dovecot for IMAP/POP3 with spam plugins to store spam message automatically into the spam folder.
After the upgrade, I was noticed by some of my users that they have in their message the same message appearing 2,3 even 10 times.
I was able to stop this after removing pigeonhole rpm (removing/disabling the config was not enough).
Would appreciate your help to understand what is wrong with my config.
