hello.
Today I had a problem (core dumped) in a dovecot installation update yesterday. After many hours I found that when one settings "protocol imap" the option "replication" causes (core dumped). In this server settings "replication" was removed leaving only the "protocol imap" (my error) I send my documentation error so they can add a validation and not generate a Fatal Error end users.
Any other info you need please email me
Thank You.
