Sorry to bother again, but the problem persist. I have checked all the configurations of dovecot, and seems all ok, but randomly the segfault pops up again, without no apparently reason. My packages are: ii dovecot-core 1:2.2.22-1ubuntu2.10 amd64 secure POP3/IMAP server - core files ii dovecot-imapd 1:2.2.22-1ubuntu2.10 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-managesieved 1:2.2.22-1ubuntu2.10 amd64 secure POP3/IMAP server - ManageSieve server ii dovecot-mysql 1:2.2.22-1ubuntu2.10 amd64 secure POP3/IMAP server - MySQL support ii dovecot-pop3d 1:2.2.22-1ubuntu2.10 amd64 secure POP3/IMAP server - POP3 daemon ii dovecot-sieve 1:2.2.22-1ubuntu2.10 amd64 secure POP3/IMAP server - Sieve filters support Can be a temporarly solution to uninstall dovecot-managesieved ?
