<body><div>Hallo Dovecot Community,</div><div><br /></div><div>wir arbeiten zur Zeit an einem Filterungssystem, welches auf einer älteren Dovecot Version von Dovecot(v2.2.22) basiert. Nun haben wir auf die aktuelle Version geupdated. (Ein Downgrade ist ausgeschlossen)</div><div><br /></div><div>Folgendes Problem besteht nun:</div><div><br /></div><div>Alle Filterordner werden in Thunderbird richtig angezeigt, sowie alle Emails, die sich in den Ordnern befinden. Soll nun eine Email geöffnet werden, dann gibt Dovecot einen Error aus und Thunderbird (v. 52.7) schließt die Email direkt wieder. Einige Emails lassen sich öffnen! Es ist immer zufällig, ob sich die Email öffnen lässt.</div><div><br /></div><div>Dovecot Version:</div><div>2.3.1 (c5a5c0c82)</div><div><br /></div><div><br /></div><div>Dovecot-config</div><div># 2.3.1 (c5a5c0c82): /etc/dovecot/dovecot.conf<br /># Pigeonhole version 0.5.devel (61b47828)<br /># OS: Linux 4.13.13-2-pve x86_64 Ubuntu 16.04.4 LTS<br />auth_mechanisms = plain login<br />dict {<br /> sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf<br />}<br />listen = *<br />log_timestamp = "%Y-%m-%d %H:%M:%S "<br />login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k<br />mail_home = /var/vmail/%d/%n<br />mail_location = sdbox:~/sdbox<br />mail_max_userip_connections = 500<br />mail_nfs_storage = yes<br />mail_plugins = quota acl fts fts_solr virtual notify<br />managesieve_notify_capability = mailto<br />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 editheader imapflags notify vnd.dovecot.duplicate<br />namespace {<br /> list = yes<br /> location = virtual:~/sdbox/Filter/:INDEX=MEMORY<br /> prefix = Filter/<br /> separator = /<br /> subscriptions = yes<br />}<br />namespace inbox {<br /> inbox = yes<br /> location =<br /> mailbox Archiv {<br /> special_use = \Archive<br /> }<br /> mailbox Archive {<br /> auto = subscribe<br /> special_use = \Archive<br /> }<br /> mailbox Archives {<br /> special_use = \Archive<br /> }<br /> mailbox "Deleted Messages" {<br /> special_use = \Trash<br /> }<br /> mailbox Drafts {<br /> auto = subscribe<br /> special_use = \Drafts<br /> }<br /> mailbox Entwürfe {<br /> special_use = \Drafts<br /> }<br /> mailbox "Gelöschte Objekte" {<br /> special_use = \Trash<br /> }<br /> mailbox Gesendet {<br /> special_use = \Sent<br /> }<br /> mailbox "Gesendete Objekte" {<br /> special_use = \Sent<br /> }<br /> mailbox Junk {<br /> auto = subscribe<br /> special_use = \Junk<br /> }<br /> mailbox Papierkorb {<br /> special_use = \Trash<br /> }<br /> mailbox Sent {<br /> auto = subscribe<br /> special_use = \Sent<br /> }<br /> mailbox "Sent Messages" {<br /> special_use = \Sent<br /> }<br /> mailbox Trash {<br /> auto = subscribe<br /> special_use = \Trash<br /> }<br /> prefix =<br /> separator = /<br />}<br />passdb {<br /> args = /etc/dovecot/dovecot-mysql.conf<br /> driver = sql<br />}<br />plugin {<br /> acl = vfile<br /> acl_anyone = allow<br /> acl_shared_dict = file:/var/vmail/shared-mailboxes.db<br /> fts = solr<br /> fts_autoindex = yes<br /> fts_solr = url=<a href="http://127.0.0.1:8983/solr/">http://127.0.0.1:8983/solr/</a><br /> quota = dict:Userquota::proxy::sqlquota<br /> quota_rule2 = Trash:storage=+100%%<br /> quota_status_nouser = DUNNO<br /> quota_status_overquota = 552 5.2.2 Mailbox is over quota<br /> quota_status_success = DUNNO<br /> sieve = /var/vmail/sieve/%u.sieve<br /> sieve_before = /etc/dovecot/sieve/before/spam-global.sieve<br /> sieve_extensions = +notify +imapflags +editheader +vnd.dovecot.duplicate<br /> sieve_max_script_size = 1M<br /> sieve_quota_max_scripts = 0<br /> sieve_quota_max_storage = 0<br />}<br />protocols = imap sieve lmtp pop3<br />service anvil {<br /> client_limit = 8192<br />}<br />service auth {<br /> client_limit = 8192<br /> unix_listener /var/spool/postfix/private/auth_dovecot {<br /> group = postfix<br /> mode = 0660<br /> user = postfix<br /> }<br /> unix_listener auth-master {<br /> mode = 0600<br /> user = vmail<br /> }<br /> unix_listener auth-userdb {<br /> mode = 0600<br /> user = vmail<br /> }<br /> user = root<br />}<br />service dict {<br /> unix_listener dict {<br /> group = vmail<br /> mode = 0660<br /> user = vmail<br /> }<br />}<br />service imap-login {<br /> process_limit = 1000<br /> process_min_avail = 32<br />}<br />service lmtp {<br /> unix_listener /var/spool/postfix/private/dovecot-lmtp {<br /> group = postfix<br /> mode = 0600<br /> user = postfix<br /> }<br /> user = vmail<br />}<br />service managesieve-login {<br /> inet_listener sieve {<br /> port = 4190<br /> }<br /> process_min_avail = 2<br /> service_count = 1<br /> vsz_limit = 128 M<br />}<br />service managesieve {<br /> process_limit = 256<br />}<br />service stats {<br /> fifo_listener stats-mail {<br /> mode = 0600<br /> user = vmail<br /> }<br />}<br />ssl_cert = </etc/ssl/mail/mail.crt<br />ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!ECDSA:CAMELLIA256-SHA:AES256-SHA:CAMELLIA128-SHA:AES128-SHA<br />ssl_dh = #
