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,
Claudio Prono.
