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 ?
Cordially,
Claudio.

Another interesting thing, noticed now: before the segfault error I have always this log:
Jul 3 11:50:26 mail dovecot: config: Error: managesieve-login: dump-capability process killed with signal 11
Jul 3 11:50:26 mail kernel: [1514971.045499] doveconf[23971]: segfault at 55d0fd61c000 ip 00007f3f7cc242d0 sp 00007ffcb29341b8 error 6 in libc-2.23.so[7f3f7cb95000+1c0000]
But I have no idea of what configuration is faulty on managesieve-login. This is the actual configuration:
doveconf -n | grep sieve
managesieve_notify_capability = mailto
managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext
sieve = /var/vmail/%d/%u/.dovecot.sieve
sieve_dir = /var/vmail/%d/%u/sieve
sieve_global_dir = /var/lib/dovecot/sieve/
sieve_storage = /var/vmail/%d/%u/sieve
protocols = " imap sieve pop3"
mail_plugins = " sieve"
Any help?

Any hint about it ? Sometimes, from my webmail I receive an error communicating with server, but no other errors.
Cordially,
