Hi All,

We're running dovecot director por proxying imap/pop queries to the backends. Yesterday we add LMTP proxying and it works fine, but we have realized that Sieve filters are no longer working after this change. Is it mandatory to add some config to the directors or backends after implementing LMTP through Director?

We use

dovecot-pigeonhole-2.2.36-8.el7.x86_64
dovecot-2.2.36-8.el7.x86_64

This is director servers config, if you also need backends config, please let me know

doveconf -n
