So when I try and create a sub mailbox in shared-folders, I get this error…

imap(pid 56143 user -----): Fatal: master: service(imap): child 56143 killed with signal 11 (core dumps disabled)

I’ve not been able to figure out how to get dovecot in OS X to core dump, so I haven’t included that. The documentation on the web doesn’t seem to apply to the version Apple ships.

Here’s dovecotd -n, with the ssl certs removed and the domain replaced with the word domain. # 2.2.5: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 13.0.0 x86_64 hfs aps_topic = com.apple.mail.XServer.b137086a-440f-45fe-89c4-8ddf798318a3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = cram-md5 plain login apop digest-md5 auth_realms = office.domain.com auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n auth_verbose = yes debug_log_path = /Library/Logs/Mail/mail-debug.log default_internal_user = _dovecot default_login_user = _dovenull disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 6 imap_id_log = * imap_id_send = "name" * "version" * imap_urlauth_submit_user = submit info_log_path = /Library/Logs/Mail/mail-info.log log_path = /Library/Logs/Mail/mail-err.log login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_access_groups = mail mail_attribute_dict = file:/Library/Server/Mail/Data/attributes/attributes.dict mail_debug = yes mail_location = maildir:/Volumes/PromiseRAID/Library/Server/Mail/Data/mail/%u mail_log_prefix = "%s(pid %p user %u): " mail_plugins = quota zlib acl fts fts_sk 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 mdbox_rotate_size = 200 M namespace acl-mailboxes { list = children location = maildir:/Library/Server/Mail/Data/mail/users/%%u:INDEX=/Library/Server/Mail/Data/mail/shared/%%u prefix = shared.%%u. separator = . subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } namespace list-archives { list = children location = maildir:/Library/Server/Mail/Data/listserver/messages/archive/lists/%%u:INDEX=/Library/Server/Mail/Data/listserver/messages/archive/shared/%%u prefix = archives.%%u. separator = . subscriptions = no type = shared } namespace shared-folders { list = yes location = maildir:/Volumes/PromiseRAID/Library/Server/Mail/Data/Shared prefix = shared-folders. separator = . subscriptions = no type = shared } passdb { driver = od } passdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file } plugin { acl = vfile:/Library/Server/Mail/Config/dovecot/global-acls:cache_secs=300 acl_anyone = allow acl_shared_dict = file:/Library/Server/Mail/Data/shared/shared-mailboxes fts = sk quota = maildir:User quota quota_warning = storage=100%% quota-exceeded %u sieve = /Library/Server/Mail/Data/rules/%u/dovecot.sieve sieve_dir = /Library/Server/Mail/Data/rules/%u stats_refresh = 30 secs stats_track_cmds = yes } postmaster_address = postmaster@office.domain.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { extra_groups = _keytabusers idle_kill = 15 mins unix_listener auth-userdb { user = _dovecot } } service dns_client { unix_listener dns-client { mode = 0600 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 } service imap { client_limit = 5 process_limit = 200 service_count = 0 } service indexer-worker { user = _dovecot } service lmtp { unix_listener lmtp { mode = 0600 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { client_limit = 5 process_limit = 200 service_count = 0 } service quota-exceeded { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-exceeded.sh unix_listener quota-exceeded { group = mail mode = 0660 user = _dovecot } user = _dovecot } service quota-warning { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-warning.sh unix_listener quota-warning { group = mail mode = 0660 user = _dovecot } user = _dovecot } service stats { fifo_listener stats-mail { mode = 0600 user = _dovecot } } ssl = required ssl_ca = ssl_cert = ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!ADH:!eNULL ssl_key = ssl_key_path = userdb { args = partition=/Library/Server/Mail/Config/dovecot/partition_map.conf enforce_quotas=no driver = od } userdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file } verbose_proctitle = yes protocol lmtp { mail_plugins = quota zlib acl fts fts_sk sieve push_notify } protocol lda { mail_plugins = quota zlib acl fts fts_sk acl sieve push_notify } protocol imap { mail_max_userip_connections = 20 mail_plugins = quota zlib acl fts fts_sk acl imap_acl imap_quota imap_zlib } protocol pop3 { mail_max_userip_connections = 6 }
