Hello Teemu,
the version of my lz4 library is the most recent lz4-1.7.5, and "dovecot -n" output is as follows:
# 2.2.30.1 (eebd877): /raid/data/module/Dovecot/sys/etc/dovecot/dovecot.conf # OS: Linux 2.6.33N7700 i686 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = sha1 info_log_path = /raid/data/module/Dovecot/sys/var/log/dovecot-info.log log_path = /raid/data/module/Dovecot/sys/var/log/dovecot.log mail_debug = yes mail_fsync = never mail_full_filesystem_access = yes mail_location = mdbox:~/mdbox mail_plugins = " fts fts_lucene zlib" mdbox_rotate_size = 32 M passdb { args = /raid/data/module/Dovecot/sys/etc/dovecot/imap.passwd driver = passwd-file } plugin { fts = lucene fts_lucene = whitespace_chars=@. zlib_save = lz4 zlib_save_level = 6 } protocols = imap ssl = required ssl_cert = </raid/data/module/Dovecot/sys/etc/ssl/certs/dovecot-rsa-cert.pem ssl_cipher_list = EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA+RC4:EECDH:EDH+aRSA:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!RC4 ssl_dh_parameters_length = 2048 ssl_key = # hidden, use -P to show it ssl_key_password = # hidden, use -P to show it ssl_prefer_server_ciphers = yes ssl_protocols = !TLSv1 !SSLv3 !SSLv2 state_dir = /raid/data/module/Dovecot/sys/var/run/dovecot userdb { args = username_format=%u /raid/data/module/Dovecot/sys/etc/dovecot/imap.passwd default_fields = uid=vmail gid=vmail home=/raid/data/MailArchive/Dovecot/%u driver = passwd-file } verbose_ssl = yes protocol imap { mail_plugins = zlib imap_zlib }
Many thanks for looking into this & best regards Andreas

Hello
Can you please provide the output of doveconf -n? The version of your lz4 library could be useful also, if it is not the distributions default. ref. https://dovecot.org/bugreport.html
