Hi, I'm trying to activate some virtual folders on a new installed dovecot server. My plan is to have two virtual folders like "All" and perhaps "Unseen", like Gmail style for the first step. - All: lists me all messages in the users mailbox - Unseen: all unseen messages in the users mailbox I'm using dovecot EE Release: ii dovecot-ee-core 1:2.2.13.8-1 amd64 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-imapd 1:2.2.13.8-1 amd64 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-lmtpd 1:2.2.13.8-1 amd64 secure LMTP server for Dovecot ii dovecot-ee-managesieved 0.4.3-1 amd64 secure ManageSieve server for Dovecot ii dovecot-ee-mysql 1:2.2.13.8-1 amd64 MySQL support for Dovecot ii dovecot-ee-sieve 0.4.3-1 amd64 sieve filters support for Dovecot But I can't get it to work. I can see the virtual folders in my Thunderbird, but the folders are empty and can't find any errors in mail log. I also tried it with "mail_debug = yes". Below is my doveconf -n: ... # 2.2.13.8 (71cc347a687c+): /etc/dovecot/dovecot.conf # OS: Linux 3.4.67-vs2.3.3.9-rol-em64t-efigpt x86_64 Debian 7.6 ext4 auth_cache_negative_ttl = 0 auth_cache_ttl = 0 auth_debug = yes auth_mechanisms = plain login auth_verbose = yes deliver_log_format = msgid=%m: %$ %p %w disable_plaintext_auth = no login_trusted_networks = $INTERNAL mail_debug = yes mail_gid = mailstore mail_location = mdbox:/home/vmail/%d/%n:INDEX=/home/dovecotindex/%d/%n mail_log_prefix = "%s(%u pid:%p session:<%{session}>): " mail_plugins = " quota mail_log notify acl zlib stats virtual" mail_shared_explicit_inbox = yes mail_uid = mailstore 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 ihave duplicate mdbox_rotate_size = 15 M namespace { list = children location = mdbox:/home/vmail/%%d/%%n:INDEX=/home/dovecotindex/%%d/%%n prefix = [shared]/%%u/ separator = / subscriptions = yes type = shared } namespace { hidden = no inbox = no list = children location = virtual:/home/virtual:INDEX=MEMORY prefix = [virtual]/ separator = / subscriptions = yes type = private } namespace inbox { inbox = yes list = yes location mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix separator = / subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-sql-account.conf driver = sql } plugin { acl = vfile acl_shared_dict = file:/home/vmail/%d/shared-mailboxes mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change save mailbox_create append mail_log_fields = uid box msgid size from mail_log_group_events = no quota = dict:Storage used::file:%h/dovecot-quota quota_rule2 = INBOX/Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 15 stats_command_min_time = 1 mins stats_domain_min_time = 12 hours stats_ip_min_time = 12 hours stats_memory_limit = 32 M stats_refresh = 30 secs stats_session_min_time = 15 mins stats_track_cmds = yes stats_user_min_time = 1 hours zlib_save = gz zlib_save_level = 9 } protocols = imap lmtp sieve service auth { unix_listener auth-userdb { group = mailstore mode = 0660 user = root } } service imap-login { inet_listener imap { port = 143 } process_limit = 256 process_min_avail = 25 service_count = 1 } service imap { process_limit = 256 process_min_avail = 25 service_count = 1 } service lmtp { inet_listener lmtp { address = * port = 24 } unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } service pop3-login { inet_listener pop3 { port = 110 } process_limit = 256 process_min_avail = 25 service_count = 1 } service pop3 { process_limit = 256 process_min_avail = 25 service_count = 1 } service quota-warning { executable = script /usr/local/rol/dovecot/quota-warning.sh unix_listener quota-warning { user = mailstore } user = mailstore } service stats { fifo_listener stats-mail { mode = 0600 user = mailstore } } ssl = no submission_host = localhost:25 userdb { args = /etc/dovecot/dovecot-sql-account.conf driver = sql } protocol lmtp { mail_fsync = optimized mail_plugins = " quota mail_log notify acl zlib stats virtual sieve zlib" } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep imap_id_log = * imap_logout_format = bytes=%i/%o session=<%{session}> mail_max_userip_connections = 40 mail_plugins = " quota mail_log notify acl zlib stats virtual imap_quota imap_acl imap_zlib imap_stats" } protocol pop3 { mail_plugins = " quota mail_log notify acl zlib stats virtual" pop3_logout_format = bytes_sent=%o top=%t/%p, retr=%r/%b, del=%d/%m, size=%s uidl_hash=%u session=<%{session}> } ... The virtual folders are stored in "/home/virtual/XXX" and are containg only the file "dovecot-virtual". Like: "/home/virtual/All/dovecot-virtual": <--------------------- * all ---------------------> Note: I just have active virtual folders on a different dovecot server version "2:2.2.13-1~auto+74". I copied the configuration from this server. The only three differences between the two servers are: - Server version is different. - The prefix of the default namespace on the new server is "prefix = INBOX/" and not "prefix =" - Mail storage and index files are seperated in different folders on the new server. Here are the relveant namespace configuraiton from the server where it ist working fine: ... namespace { list = children location = mdbox:/home/vmail/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { hidden = no inbox = no list = children location = virtual:/home/virtual:INDEX=~/virtual prefix = [rolmail]/ separator = / subscriptions = yes type = private } namespace inbox { inbox = yes location mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix separator = / type = private } ... Have you any hint for me how I can fix my problem. Thanks and regards Urban Loesch
