Shared mailboxes - Can't open mailbox shared-boxes/user/name.lastname: Character not allowed in mailbox name: '.'
by Marcio Vogel Merlone dos Santos 25 Oct '18

Hi, I am trying to make shared folders work on my server (Ubuntu 18.04, Dovecot 1:2.2.33.2-1ubuntu4.1). Mails are on Maildir++ local filesystem with '.' as layout separator and ALL 100+ users logins fits a template name.lastname, with a dot in the middle. I set up listescape but no luck. When I test with doveadm: root@mail:/etc/dovecot/conf.d# doveadm acl debug -u marcio.merlone(a)a1.ind.br shared-boxes/user/name.lastname doveadm(marcio.merlone(a)a1.ind.br): Error: Can't open mailbox shared-boxes/user/name.lastname: Character not allowed in mailbox name: '.' root@mail:/etc/dovecot/conf.d# Is there something I can do besides changing layout separator?

Exclude userdb from iterate users
by Ángel L. Mateo 25 Oct '18

25 Oct '18

Hi, I have a system with various userdbs defined, mostly all of them based on ldap (and a few passwd-files). I want one of my ldap userdbs not to be used in "doveadm user -A" commands, that is to be excluded in iterate searchs. I have no iterate_filter neither iterate_attrs configured in that userdb, but it is still used. Is it possible? How? -- Angel L.

doveadm backup: Error: Both source and destination mail_location points to same directory
by Martin Johannes Dauser 24 Oct '18

24 Oct '18

Hello! I'm using 2 namespaces, "inbox" for INBOX and it's subfolders and "special" containing folders like Sent, Junk or Drafts. Though both use mdbox I decided to represent those namespaces in different locations "mdbox:~/mail" and "mdbox:~/mail_special_folders". The main reason to use 2 namespaces was to keep special_use folders out of INBOX by using the prefix attribute -- it's rather cosmetic. ├── INBOX │ ├── SubFolder1 │ ├── SubFolder2 │ └── SubFolder3 ├── Sent ├── Trash ├── Drafts ├── Junk ├── Templates ├── This is Ham └── Report Spam Now I want to export the emails of some former users to common known maildir or mbox format to be able to hand them over on CD. The problem is that a conversion with doveadm backup fails. I guess this is due to namespace special which is configured with a manual location attribute instead of utilising mail_location. But even telling doveadm to backup only one namespace leads to the identical error (extract of debug message at bottom). As this is a RHEL7 server, the dovecot version is an old 2.2.10 and I don't expect software debugging -- I just ask if I did some misconfiguration or a failure in the command. I already thought of merging the locations of both namespaces. Yet, I'm not sure how to achieve this. >From /etc/dovecot/conf.d/10-mail.conf mail_location = mdbox:~/mail namespace inbox { type = private hidden = no ignore_on_failure = no inbox = yes list = yes location = prefix = INBOX/ separator = / subscriptions = yes } namespace special { type = private hidden = no ignore_on_failure = no inbox = no list = yes location = mdbox:~/mail_special_folders prefix = separator = / subscriptions = yes } HOME is set by LDAP user_attrs = =home=/srv/mail/%Ld/%Ln,=uid=20000,=gid=20000,imapQuota=quota_rule=*:st orage=%$G Identical debug messages of following commands: # dsync -Dv backup -u bob(a)cs.sbg.ac.at maildir:/home/Mailexport/bob or # doveadm -Dv backup -u bob(a)cs.sbg.ac.at maildir:/home/Mailexport/bob or # doveadm -Dv backup -u bob(a)cs.sbg.ac.at -n inbox maildir:/home/Mailexport/bob or # doveadm -Dv backup -u bob(a)cs.sbg.ac.at -n special maildir:/home/Mailexport/bob ... doveadm(bob(a)cs.sbg.ac.at): Debug: Namespace inbox: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mail doveadm(bob(a)cs.sbg.ac.at): Debug: fs: root=/srv/mail/cs.sbg.ac.at/bob/mail, index=, indexpvt=, control=, inbox=, alt= doveadm(bob(a)cs.sbg.ac.at): Debug: Namespace special: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mail_special_folders doveadm(bob(a)cs.sbg.ac.at): Debug: fs: root=/srv/mail/cs.sbg.ac.at/bob/mail_special_folders, index=, indexpvt=, control=, inbox=, alt= doveadm(bob(a)cs.sbg.ac.at): Debug: Namespace INBOX/: Using permissions from /srv/mail/cs.sbg.ac.at/bob/mail: mode=0774 gid=default dsync(bob(a)cs.sbg.ac.at): Debug: Effective uid=20000, gid=20000, home=/srv/mail/cs.sbg.ac.at/bob dsync(bob(a)cs.sbg.ac.at): Debug: Quota root: name=User quota backend=dict args=:file:/srv/mail/cs.sbg.ac.at/bob/dovecot-quota ... dsync(bob(a)cs.sbg.ac.at): Debug: Namespace inbox: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/home/Mailexport/bob dsync(bob(a)cs.sbg.ac.at): Debug: maildir++: root=/home/Mailexport/bob, index=, indexpvt=, control=, inbox=/home/Mailexport/bob, alt= dsync(bob(a)cs.sbg.ac.at): Debug: Namespace special: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mail_special_folders dsync(bob(a)cs.sbg.ac.at): Debug: fs: root=/srv/mail/cs.sbg.ac.at/bob/mail_special_folders, index=, indexpvt=, control=, inbox=, alt= dsync(bob(a)cs.sbg.ac.at): Error: Both source and destination mail_location points to same directory: /srv/mail/cs.sbg.ac.at/bob/mail_special_folders/mailboxes Many thanks for any hint Martin

Bug: 'noreplicate' database extra field ingnored
by Phil 22 Oct '18

22 Oct '18

The 'noreplicate' user database field described in the wiki appears to make no difference as to whether an account gets replicated or not. My sql user query returns a 'noreplicate' field and I can confirm that this is getting set using 'doveadm user', however when I add a new account with noreplicate=true it gets replicated regardless. User query: user_query = SELECT home, uid, gid, noreplicate FROM mail_accounts WHERE address = '%u' # doveadm user user1(a)mydomain.com field value uid 1000 gid 1000 home /mail/domains/mydomain.com/user1/Maildir mail maildir:/mail/domains/mydomain.com/user1/Maildir noreplicate t # 2.3.3 (dcead646b): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.3 (f018bbab) # OS: FreeBSD 11.2-RELEASE-p4 amd64 # Hostname: mx doveadm_password = # hidden, use -P to show it doveadm_port = 2727 imap_client_workarounds = delay-newmail tb-extra-mailbox-sep listen = * mail_location = maildir:%h 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 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 = } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_replica = tcps:mail2.<mydomain>.com } protocols = imap lmtp submission replication_full_sync_interval = 6 hours service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { user = vmail } user = root } service doveadm { inet_listener { port = 2727 ssl = yes } } service imap-login { inet_listener imaps { address = xxx.xxx.xxx.xxx port = 993 } process_limit = 256 process_min_avail = 6 service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 user = vmail } } ssl = required ssl_cert = </etc/ssl/certs/mail.<mydomain>.com.pem ssl_client_ca_dir = /etc/ssl/ ssl_client_ca_file = /etc/ssl/cert.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 100 } protocol lda { postmaster_address = postmaster@<mydomain>.com sendmail_path = /usr/sbin/sendmail }

Fatal: setgid, imap connections dropped.
by J. de Meijer 19 Oct '18

19 Oct '18

Hi, I'm getting errors with my IMAP setup. Basically, everything seems to work. Mail is delivered nicely from Postfix to Dovecot via LMTP. Dovecot does the authentication to LDAP (also for Postfix). Users are able to send mail via authenticated submission (Postfix) and login into IMAP and POP. However, IMAP connections are dropped frequently with an "ERROR: Connection dropped by IMAP server.". After pressing reload on the webmail, or refreshing in the client might help for a short period. So it fails intermittently. The errors in the maillog are below. It seems to be mixing up users kind of randomly. I think when multiple connections are made at the same time. Did a lot of searching, put couldn't find an answer to this problem. All I can find is related to LDA, which I'm not using. Any help would be appreciated.

trouble with ssl disable in centos 7 with version 1.0 1.2 and 3.10
by Joseph Harth 19 Oct '18

19 Oct '18

I am trying to use dovecot without ssl in centos 7. It works with imap but I am not able to make it work with pop3. Pop3 only works with ssl=yes. I can use dovecot in centos 4 ok. I get the same error with thunderbird and outlook. But for some reason it works when I telnet to port 110 and do retr 1. I was able to work pam and shadow passwords. this is the output that does not work with tls disabled Oct 18 13:30:17 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/authOct 18 13:30:17 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/lib20_auth_var_expand_crypt.soOct 18 13:30:17 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.soOct 18 13:30:17 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.datOct 18 13:30:17 auth: Debug: auth client connected (pid=22513)Oct 18 13:30:17 auth: Debug: client in: AUTH 1 PLAIN service=pop3 session=WXv1I4R4FOXAqAAK lip=192.168.0.37 rip=192.168.0.10 lport=110 rport=58644Oct 18 13:30:17 auth: Debug: client passdb out: CONT 1Oct 18 13:30:17 auth: Debug: client in: CONT 1 == (previous base64 data may contain sensitive data)Oct 18 13:30:17 auth-worker(22515): Debug: Loading modules from directory: /usr/lib64/dovecot/authOct 18 13:30:17 auth-worker(22515): Debug: Module loaded: /usr/lib64/dovecot/auth/lib20_auth_var_expand_crypt.soOct 18 13:30:17 auth-worker(22515): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.soOct 18 13:30:17 auth-worker(22515): Debug: shadow(joe2,192.168.0.10,<WXv1I4R4FOXAqAAK>): lookupOct 18 13:30:17 auth: Debug: client passdb out: OK 1 user=joe2Oct 18 13:30:17 auth: Debug: master in: REQUEST 2718302209 22513 1 05eac7a2917ce3bc1f0f359b21b138e6 session_pid=22516Oct 18 13:30:17 auth-worker(22515): Debug: passwd(joe2,192.168.0.10,<WXv1I4R4FOXAqAAK>): lookupOct 18 13:30:17 auth: Debug: master userdb out: USER 2718302209 joe2 system_groups_user=joe2 uid=660 gid=661 home=/home/joe2Oct 18 13:30:17 pop3(joe2)<22516><WXv1I4R4FOXAqAAK>: Debug: Effective uid=660, gid=661, home=/home/joe2Oct 18 13:30:17 pop3(joe2)<22516><WXv1I4R4FOXAqAAK>: Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail/:INBOX=/var/mail/joe2Oct 18 13:30:17 pop3(joe2)<22516><WXv1I4R4FOXAqAAK>: Debug: fs: root=/home/joe2/mail, index=, indexpvt=, control=, inbox=/var/mail/joe2, alt=Oct 18 13:30:17 pop3(joe2)<22516><WXv1I4R4FOXAqAAK>: Debug: Mailbox INBOX: Mailbox opened because: POP3 INBOXOct 18 13:30:17 pop3(joe2)<22516><WXv1I4R4FOXAqAAK>: Debug: Mailbox INBOX: UID 30: Opened mail because: accessOct 18 13:30:17 pop3(joe2)<22516><WXv1I4R4FOXAqAAK>: Debug: Mailbox INBOX: UID 30: Opened mail because: RETR This is the output with TLS and it works Oct 18 13:30:32 auth: Debug: auth client connected (pid=22542)Oct 18 13:30:33 auth: Debug: client in: AUTH 1 PLAIN service=pop3 secured=tls session=44feJIR4FeXAqAAK lip=192.168.0.37 rip=192.168.0.10 lport=110 rport=58645 ssl_cipher=ECDHE-RSA-AES128-GCM-SHA256 ssl_cipher_bits=128 ssl_pfs=ECDH ssl_protocol=TLSv1.2Oct 18 13:30:33 auth: Debug: client passdb out: CONT 1Oct 18 13:30:33 auth: Debug: client in: CONT 1 == (previous base64 data may contain sensitive data)Oct 18 13:30:33 auth-worker(22515): Debug: shadow(joe2,192.168.0.10,<44feJIR4FeXAqAAK>): lookupOct 18 13:30:33 auth: Debug: client passdb out: OK 1 user=joe2Oct 18 13:30:33 auth: Debug: master in: REQUEST 4165992449 22542 1 cb03b70f92c0c5c030e25a39ea4b8518 session_pid=22543Oct 18 13:30:33 auth-worker(22515): Debug: passwd(joe2,192.168.0.10,<44feJIR4FeXAqAAK>): lookupOct 18 13:30:33 auth: Debug: master userdb out: USER 4165992449 joe2 system_groups_user=joe2 uid=660 gid=661 home=/home/joe2Oct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Effective uid=660, gid=661, home=/home/joe2Oct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail/:INBOX=/var/mail/joe2Oct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: fs: root=/home/joe2/mail, index=, indexpvt=, control=, inbox=/var/mail/joe2, alt=Oct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Mailbox INBOX: Mailbox opened because: POP3 INBOXOct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Mailbox INBOX: UID 30: Opened mail because: accessOct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Mailbox INBOX: UID 30: Opened mail because: RETROct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Mailbox INBOX: UID 31: Opened mail because: accessOct 18 13:30:33 pop3(joe2)<22543><44feJIR4FeXAqAAK>: Debug: Mailbox INBOX: UID 31: Opened mail because: RETR

Problems recovering IMAP Data
by Albert Whale 18 Oct '18

18 Oct '18

HELP, I have experience an issue with the long running IMAP service using Dovecot 2.1.15. I have replaced the interface cards (suspected failure), and I have only recently been able to retrieve my Inbox (1.45GB) via POP3 protocol (I normally run IMAP) I am suspecting a corrupted dovecot.index, but which one? I have counted 260 files in my IMAP tree with the word dovecot. I cannot determine which folder is corrupted with 2.1.5 even with the Mail Debug option. How can I recover the use of my IMAP configuration? Thank you.

dovecot passdb driver=checkpassword as external script for block ip

Refer to https://dovecot.org/pipermail/dovecot/2015-March/099971.html https://wiki.dovecot.org/PasswordDatabase I tried to repeat the same thing. Set these passdb: passdb { args = /myscript.sh ip=%r driver = checkpassword result_failure = return-fail result_success = continue } passdb { args = /etc/dovecot/dovecot-sql.conf.ext ( my working auth method ) driver = sql } Created executable /myscript.sh: #!/bin/sh exit 1 But I saw in the logs: dovecot[15111]: auth: Error: checkpassword(techdept(a)nestormedia.com,192.168.99.128,<Mos6jW94XNzAqGOA>): Child 15115 exited with status 1 dovecot[18016]: imap-login: Login: user=....[successful login] Why result_failure=return-fail from first passdb does not work?

Replication 'noreplicate' field usage
by Phil 17 Oct '18

17 Oct '18

I've set up replication as per the wiki under 2.3.3 and in my SQL user query I am returning a 'noreplicate' field, this is a boolean and returns true for all users at the moment. However when I do "doveadm replicator status '*'" it lists all users in my database suggesting it is trying to sync all users regardless of the noreplicate field. ``` user_query = SELECT home, uid, gid, noreplicate FROM users WHERE address = '%u' ``` It seems that the noreplicate field is being ignored, am I using it correctly?

Corrupted dbox file/index
by Raymond Sellars 15 Oct '18

15 Oct '18

Hi Looking for some insight into mdbox index file management and recovery from corruptions. I have a two node cluster on NFS with proxy director in front for user stickness. One node (a nominated master) bidirectionally replicates to a 3rd node on a DR site. We periodically get index file corruptions resulting in rebuilds. However the user experience is poor as messages read/deleted from months/years ago all reappear as unread again. We've seen corruption because of NFS NTP time sync problems, proxy not being stick, but also the DR node being off line for a while and then tripping corruption within production when it comes back on. Error message example (1 of): Error: Corrupted dbox file /mailshare/.. (removed) ../home/mail/storage/m.4 (around offset=993548): EOF reading msg header (got 0/30 bytes) https://wiki2.dovecot.org/MailboxFormat/dbox- i've read up on all the documentation I can find and understand " you must not lose the dbox index files, they can't be regenerated without data loss." Questions: #1 Any additional tips for avoiding mdbox index corruptions with dsync? Or should I revert to maildir format? I like the performance premise of the mdbox but these index corruptions are a reliability issue. #2 I'm guessing read status is one of the meta data items lost. But its seems it can't recover it from dovecot.index.backup files either. Any technique to preserve that item as its key to the user experience? #3 If index/transaction logs are so critical is there some kind of check point backups I can take? Native dovecot feature or do I need to script something. #4 I've noticed that rebuilding the index does not work if the dovecot.index.log file is lost (deleted as a hard test). The dovecot.index.cache can be but once the log file i gone messages are not automatically (or manually that i can find) recovered from the storage directory. I've not seen any dovecot.index.log file corruptions but that file seems very high risk. If rebuilding the index only from the log file or a combination process from storage directory? Is there perhaps an option to just use the transaction log and not the index? Although that doesn't sound wise for performance. #5 In additional to status UNREAD we also notice files moved to the trash reappear. Is that expected behavior? Thanks Raymond

Problems with qouta_clone plugin

Hello I'm having troubles getting the quota_clone plugin to work for me. iø, trying to put the quota values into to to fields, messages and usage_in_bytes, in the mysql database. The quotas are getting written to the maildirsize file and can be updated with the doveadm quota recalc -A or -u "*" command But i can't seem to get it to trigger the quota_clone plugin, not even an error or a warning..

Struggling to get dovecot working with postfix auth
by Laura Smith 11 Oct '18

11 Oct '18

Hi, I am trying to create an authenticated relay server using Postfix and Dovecot. However I am having two problems : (a) If I create a dovecot config entry as follows : unix_listener /var/spool/postfix-authrelay/private/dovecot-auth { group = postfix mode = 0666 user = postfix } Dovecot is unable to create the socket ? I thought surely if dovecot is started as root it should create the socket before dropping privileges ? (b) The alternative method of TCP SASL is not working either: 250 DSN ehlo localhost 250-foobar.example.com 250-PIPELINING 250-SIZE 20480000 250-ETRN 250-AUTH PLAIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN AUTH PLAIN <none_of_your_business> 535 5.7.8 Error: authentication failed: and in the logs... 2018-10-11T10:17:40.491483+01:00 X postfix-authrelay/smtpd[18312]: warning: X[X]: SASL PLAIN authentication failed: #### #### postconf #### >postconf -a cyrus dovecot > postconf -c /etc/postfix-authrelay | fgrep sasl broken_sasl_auth_clients = no cyrus_sasl_config_path = lmtp_sasl_auth_cache_name = lmtp_sasl_auth_cache_time = 90d lmtp_sasl_auth_enable = no lmtp_sasl_auth_soft_bounce = yes lmtp_sasl_mechanism_filter = lmtp_sasl_password_maps = lmtp_sasl_path = lmtp_sasl_security_options = noplaintext, noanonymous lmtp_sasl_tls_security_options = $lmtp_sasl_security_options lmtp_sasl_tls_verified_security_options = $lmtp_sasl_tls_security_options lmtp_sasl_type = cyrus proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $smtpd_sender_login_maps $sender_bcc_maps $recipient_bcc_maps $smtp_generic_maps $lmtp_generic_maps $alias_maps $smtpd_client_restrictions $smtpd_helo_restrictions $smtpd_sender_restrictions $smtpd_relay_restrictions $smtpd_recipient_restrictions $address_verify_sender_dependent_default_transport_maps $address_verify_sender_dependent_relayhost_maps $address_verify_transport_maps $fallback_transport_maps $lmtp_discard_lhlo_keyword_address_maps $lmtp_pix_workaround_maps $lmtp_sasl_password_maps $lmtp_tls_policy_maps $mailbox_command_maps $mailbox_transport_maps $postscreen_discard_ehlo_keyword_address_maps $rbl_reply_maps $sender_dependent_default_transport_maps $sender_dependent_relayhost_maps $smtp_discard_ehlo_keyword_address_maps $smtp_pix_workaround_maps $smtp_sasl_password_maps $smtp_tls_policy_maps $smtpd_discard_ehlo_keyword_address_maps $smtpd_milter_maps $virtual_gid_maps $virtual_uid_maps proxy_write_maps = $smtp_sasl_auth_cache_name $lmtp_sasl_auth_cache_name $address_verify_map $postscreen_cache_map send_cyrus_sasl_authzid = no smtp_sasl_auth_cache_name = smtp_sasl_auth_cache_time = 90d smtp_sasl_auth_enable = no smtp_sasl_auth_soft_bounce = yes smtp_sasl_mechanism_filter = smtp_sasl_password_maps = smtp_sasl_path = smtp_sasl_security_options = noplaintext, noanonymous smtp_sasl_tls_security_options = $smtp_sasl_security_options smtp_sasl_tls_verified_security_options = $smtp_sasl_tls_security_options smtp_sasl_type = cyrus smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination smtpd_relay_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = no smtpd_sasl_exceptions_networks = smtpd_sasl_local_domain = $myhostname smtpd_sasl_path = inet:localhost:7425 smtpd_sasl_security_options = noanonymous smtpd_sasl_service = smtp smtpd_sasl_tls_security_options = $smtpd_sasl_security_options smtpd_sasl_type = dovecot #### #### DOVECONF #### > doveconf -n # 2.3.1 (8e2f634): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.1 (d9bc6dfe) # OS: Linux 4.12.14-lp150.12.19-default x86_64 # Hostname: test.example.com 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 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 = } passdb { driver = pam } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } service auth { inet_listener { address = 127.0.0.1 port = 7425 } inet_listener { address = ::1 port = 7425 } # If I disable this, dovecot loads fine, but the tcp auth is unusable ? # If I enable this, dovecot is unable to create the socket ? # unix_listener /var/spool/postfix-authrelay/private/dovecot-auth { # group = postfix # mode = 0666 # user = postfix # } } ssl = no ssl_cipher_list = ALL:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK:!RC4:!ADH:!LOW@STRENGTH ssl_options = no_compression ssl_prefer_server_ciphers = yes userdb { driver = passwd }

Renewal of Let's Encrypt Certificates in Dovecot
by Ignacio Garcia 11 Oct '18

11 Oct '18

Hi there. I've been using Dovecot for quite some time now but I just started using Let's Encrypt certs. Since LE certs are renewed automatically without user intervention I'm wondering if I will need to restart dovecot after that renewal... Has anybody had any experience with that? Thanks so much for your help! Ignacio

index corruption weirdness
by William Taylor 10 Oct '18

10 Oct '18

We have started seeing index corruption ever since we upgraded (we believe) our imap servers from SL6 to Centos 7. Mail/Indexes are stored on Netapps mounted via NFS. We have 2 lvs servers running surealived in dr/wlc, 2 directors and 6 backend imap/pop servers. Most of the core dumps I've looked at for different users are like "Backtrace 2" with some variations on folder path. This latest crash (Backtrace 1) is different from others I've seen.

Problem getting quota-warning script to function.
by Ted 10 Oct '18

10 Oct '18

Hello, I'm trying to implement quota enforcement in our mailservers, and it is all working properly except that the quota warnings are not firing when the quota levels are passed. the server stops accepting email when the quota is reached, and you can see tyhe quota usage through the email client connected through, but as the quota passes the set levels the /usr/local/bin/quota-warning.sh script is not called. I checked from the appropriate user and the script executes from the command line with no problem, but dovecot does not invoke it when the quota levels are crossed. The relevant configs are below, any ideas about what the problem may be or how I should approach this? /etc/dovecot/dovecot.conf ## Dovecot configuration file # Protocols we want to be serving. protocols = imap pop3 lmtp sieve mailbox_list_index = yes # Avoid spending excessive time waiting for the quota calculation to finish when # mails' vsizes aren't already cached.

immediate delete of mails
by tselmeci＠486.hu 10 Oct '18

10 Oct '18

Hello all! I've got a home server running on an ARM Cortex-A7 with my custom Linux distribution. It's also responsible for handling incoming and outgoing mails. The SMTP server is OpenSMTPD-6.0.3p1. I'm using Dovecot-2.3.2.1 to export the mails (mailbox storage format) using IMAP. My old server used to have Dovecot-1.2.0 and honestly, it was absolutely sufficient for me. However, I've decided to use the latest Dovecot on my new system, since all other software components of my system are up-to-date. With my simple IMAP-configuration Dovecot is running fine, expect for one thing: when I press DEL in the mailer client, the mails don't get deleted. They simple reside in the mailbox file. It annoys me a lot, since the mailer client regularly makes them appear with a different (grey) color. The mailer client is Sylpheed and I'm not willing to use another one. I've already tried Thunderbird, Evolution, Claws-mail, Sylpheed, and Sylpheed suits best to my needs. The funny thing is that with the same Sylpheed the old Dovecot was willing to physically remove the mails from mailbox file, but the new Dovecot isn't willing to do so. I've tried to search for an appropriate configuration option, but didn't find what I exactly need. Auto expunge, command-line expunging are nice, but I do want immediate mail delete from mailbox file when I press DEL in the mailer client. I know this can be dangerous and degrades performance. Is there any option to configure Dovecot to behave like this? If it needs to recompile Dovecot I'm also in ;) Thanks a lot! ----------------------------------------------- dovecot -n output: # 2.3.2.1 (0719df592): /etc/dovecot.conf # OS: Linux 4.18.9 armv7l # Hostname: 486 auth_mechanisms = plain login base_dir = /var/run/dovecot/ default_client_limit = 30 default_process_limit = 10 disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.txt mail_gid = 0 mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_uid = 0 namespace { hidden = no inbox = yes list = yes location = mailbox { auto = create special_use = \Drafts name = Drafts } mailbox { auto = create special_use = \Sent name = Sent } mailbox { auto = create special_use = \Trash name = Trash } prefix = type = private name = inbox } passdb { driver = passwd } passdb { driver = shadow } protocols = imap service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict-async { name = dict-async } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap-hibernate { name = imap-hibernate } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service imap-master { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service old-stats-mail { name = old-stats } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service stats-reader { name = stats } service submission { name = submission-login } service login/submission { name = submission } ssl = no submission_max_mail_size = 0 userdb { driver = passwd } verbose_proctitle = yes -- Selmeci, Tamás http://www.486.hu/

Submission / Postfix / XCLIENT
by Anton Dollmaier 09 Oct '18

09 Oct '18

Hi all, while testing the new Dovecot Submission Proxy feature, which we greatly appreciate and have been anticipating for a long time, some issues occured. Dovecot is unable to submit mails via XCLIENT: < XCLIENT ADDR=185.115.176.12PORT=39074 > 501 5.5.4 Bad ADDR syntax: 185.115.176.12PORT=39074 Postfix is unable to parse the XCLIENT command from Dovecot submission proxy, as a space seems to be missing. After checking the source code, the issue looks easy to fix - at least to me as a non-Developer. I created my first pull request for that: > https://github.com/dovecot/core/pull/90 Would be great to see this merged. Any additional comments are also appreciated. Best, Anton

iterate query and dsync replication 2.2.33.2
by Matt Bryant 08 Oct '18

08 Oct '18

All, According to doco replication gets its list of users to replicate from the iterate query but this doesn't seem to be the case or its just being totally ignored .. Have ldap passbd and sql userdb, with the iterate query in the userdb sql file. -The query itself returns the handful of users I want to replicate BUT if I run the command dovecot replicator status '*' it shows pretty much all users in the system .. is there a bug here or is documentation just completely wrong when it comes to what is/is not replicated. rgds Matt

VOLATILEDIR not really used?
by Tom Sommer 08 Oct '18

08 Oct '18

Hi According to the docs, setting VOLATILEDIR will improve I/O performance when using NFS - but as far as I can see, only vsize lock-files are put here, and little else? Is this correct, and if so are there any plans to move dotlocks etc. to this directory? Thanks. -- Tom

doveadm quota error output in some cases
by Kai Schaetzl 05 Oct '18

05 Oct '18

I am testing a special setup on one machine where I want to put some local users that get mail locally to /home user directories via postfix transport map local: for historical and practical reasons. Other users are setup as virtual users. The local users are *also* setup as virtual users for dovecot so that I can retrieve the mail via dovecot. I changed the SQL for dovecot user_query, so that it gets the local uid and gid (and doesn't use vmail) and also gets the home directory in /home for only those users. After a bit of experimenting this works fine and I can retrieve mail via dovecot. However, there are two problems with quota and one of them has "doveadm get quota" spew out a lot of garbage that I think should actually go to a log and not to the program output. When I run a doveadm quota get -A or -u user I get four errors of this kind (for user/domain storage and message limit) for each special user: doveadm(user): Error: Failed to get quota resource STORAGE: quota-dict: dict_lookup(priv/quota/storage) failed: net_connect_unix (/var/run/dovecot/dict) failed: Permission denied (euid=500(user) egid=200(vmail) missing +r perm: /var/run/dovecot/dict, dir owned by 0:0 mode=0755) (reply took 0.000 secs (0.000 in dict wait, 0.000 in other ioloops, 0.000 in locks)) Then the normal program output follows, with error lines for these special users, of course: user STORAGE error error error The reason is that /var/run/dovecot/dict is owned by vmail:vmail (not root:root as the 0:0 suggests). I don't see a way to change this without blocking the "real" virtual users that use vmail:vmail. Shouldn't this massive error output rather go to a log? (dovecot/error.log) Or: is there a way to avoid this? /var/run/dovecot/dict is a socket. I didn't want to fiddle with it. Can I change the permissions so that it can also be accessed by other system users? Probably only to make it world-readable? If so, what are the implications of doing that? Thanks, Kai

Username aliases
by Eirik Rye 05 Oct '18

05 Oct '18

Hi, Our organization is currently using a passwd-file user database for our Dovecot installs. However, we now want to provide simple username aliases. We currently use usernames that are -not- equal to the email address, but due to the fact that many major email clients/providers do not even allow you to specifiy a username, we now want to provide aliases where the username is equal to the email address. A simple solution would be to duplicate the lines in the passwd-file, with the email address as the username, but this does not seem be ideal due to data duplication. Ideally, there would be a secondary 'alias' userdb, which on a match would then restart the search in the primary passwd-file userdb using the new username. Is this possible? What would be the best way to go about this?

vpopmail
by Eric Broch 04 Oct '18

04 Oct '18

Hello list, I run Dovecot with the vpopmail driver and have found that it authenticates against the clear text password in the vpopmail database. Is there a configuration option either at compile time, link time, or a setting in one of the configuration files that tells the program to authenticate against the hash instead of the clear text? -- Eric Broch White Horse Technical Consulting (WHTC)

Authenticate users using their firstname
by Fady AL HAYALI 04 Oct '18

04 Oct '18

Hi, I'm setting up a Postfic and Dovecot with LDAP email server. My users in LDAP is like this: dn: uid=firstname,ou=People,dc=domain,dc=com uid: firstname uidNumber: 4025 gidNumber: 4025 givenName: firstname objectClass: top objectClass: person objectClass: posixAccount objectClass: shadowAccount objectClass: organizationalPerson objectClass: inetOrgPerson loginShell: /bin/bash homeDirectory: /home/firstname cn: firstname lastname mail: firstname.lastname(a)domain.com<mailto:firstname.lastname@domain.com> This is how I connect Dovecot with LDAP hosts = ldapserver ldap_version = 3 base = ou=People,dc=domain,dc=com deref = never scope = subtree user_attrs = user_filter = (&(objectclass=inetOrgPerson)(uid=%n) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectclass=inetOrgPerson)(uid=%n)) default_pass_scheme = SSHA When I enter a user's email address and password as the following: email: firstname.lastname(a)domain.com<mailto:firstname.lastname@domain.com> password: password and according to my setting which I used "%n" as you see above, the username used to authenticate is "firstname.lastname". I checked the Dovecot variables but I couldn't find something useful in this case to manipulate the "%n" variable. I would like to keep using email addresses as "firstname.lastname(a)domain.com"<mailto:firstname.lastname@domain.com> but authenticate users using their first name. I really hit a wall here and any help will be much appreciated.

Possible architecture ?
by Alexandre Ellert 03 Oct '18

03 Oct '18

Hi, I'd like to achieve the following setup whit dovecot using multiple servers : - one server dedicated to all client IMAP (TLS) connections (i <http://mail.numeezy.com>map.mymaindomain.com, see below ) - each backend server has it's own local storage. no replication - each backend server responsible of a few domains - each backend server has it's own Mysql local database for user's passwords. ===> Server 1 : domains A, B and C ====> i <http://mail.numeezy.com>map.mymaindomain.com ===> Server 2 : domains D, E and F (143 TLS / 993 SSL) ===> Server 3 : domains G, H For example, if a user connects from domain E to i <http://mail.numeezy.com> map.mymaindomain.com, will Dovecot be able to use password database hosted on Server 2 ? Thank you ! Alex

Delete vs. Expunge in Public Namespace
by Chris 03 Oct '18

03 Oct '18

All, my IMAP client [1] marks messages as deleted, but doesn't expunge. Dovecot (2.2.27-3+deb9u2) expunges them. Is this because the mailbox is part of public namespace? .... ::1.38247-::1.00143: MALP6 STORE 48,49,50,51,52,53,54,55,56,57,58,59,60,61 +FLAGS (\Deleted) ::1.00143-::1.38247: * 48 FETCH (FLAGS (\Deleted \Seen)) * 49 FETCH (FLAGS (\Deleted \Seen)) * 50 FETCH (FLAGS (\Deleted \Seen)) * 51 FETCH (FLAGS (\Deleted \Seen)) * 52 FETCH (FLAGS (\Deleted \Seen)) * 53 FETCH (FLAGS (\Deleted \Seen)) * 54 FETCH (FLAGS (\Deleted \Seen)) * 55 FETCH (FLAGS (\Deleted \Seen)) * 56 FETCH (FLAGS (\Deleted \Seen)) * 57 FETCH (FLAGS (\Deleted \Seen)) * 58 FETCH (FLAGS (\Deleted \Seen)) * 59 FETCH (FLAGS (\Deleted \Seen)) * 60 FETCH (FLAGS (\Deleted \Seen)) * 61 FETCH (FLAGS (\Deleted \Seen)) MALP6 OK Store completed. ::1.38247-::1.00143: MALP7 SEARCH DELETED ....

Need to convert mbox to Maildir
by Mark Foley 02 Oct '18

02 Oct '18

I have a mbox file of emails. I want to convert this to Maildir giving me individual message files per email. I've looked at dsync, but as far as I can tell this wants a specific target user and it appears that it will "distribute" the converted messages into that user's INBOX. I don't want to put these mbox messages into any particular user's Maildir hierarchy, just export to file-per-message format to a destination directory of my choosing. Is this possible? THX --Mark

Help for UID THREAD and SORT optimization
by Alessio Cecchi 02 Oct '18

02 Oct '18

Hello, we are developing a library to show last arrived messages of all threads in a folder with more than 300k messages. As per the RFC 5256, the IMAP thread command has only the option to specify the grouping criteria (REFERENCES vs ORDEREDSUBJECT). So we implemented an algorithm which gets the full UID SORT ordered by date in reverse order then gets all thread relations and then post process all outputs to obtain the final result. Once we have both output we loop through the first uids set (which is ordered) and for every item of it we loop through the other uids set with all the thread relations. If the uid of the first set is contained in one of the elements of the thread messages, we pick it up and push it in the resulting array. This is a pseudo-code that shows what we are doing: array_of_latest_messages_in_thread = [] array_of_sorted_uids = [n,n,n,n,...] // UID SORT (REVERSE DATE) UTF-8 ALL array_of_thread_uids = [n,[n,n],n,[n,n,n],[n,n],n,n,...] // UID THREAD (REFERENCES) UTF-8 ALL foreach(array_of_sorted_uids as s_uid){ foreach(array_of_thread_uids as t_uids){ if(t_uids contains s_uid){ // or a function to loop recursively t_uids to search if a leaf is equal to s_uid array_of_latest_messages_in_thread.push(s_uid) break } } } We have also made some little optimizations in the above code like for example skipping from the outer loop the uids already processed in the inner loop that have not being selected. Anyway, the loop is very expensive in term of computation and we are wondering if there is a better approach to this issue directly using IMAP instead of post processing the output of the two commands at application level. Thanks. -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Bug in conditionals to assign values to variables?
by Angel L. Mateo 02 Oct '18

02 Oct '18

Hi, According to https://wiki2.dovecot.org/Variables you could use conditionals to assign values to a varible. The syntax is: %{if;value1;operator;value2;value-if-true;value-if-false} where any of the fields can refer to another field using %v or %{value} syntax. The problem is that when I use a config like: user_attrs = ...,=relpath=%{if;%u;eq;somevalue;valuetrue;valuefalse} it works without any problem. But when I use: user_attrs = ...,=relpath=%{if;%{user};eq;somevalue;valuetrue;valuefalse} then it reports in logs: Sep 28 14:23:22 myotis60 dovecot: auth: Error: var_expand_long(if;%{user}) failed: if: requires four or five parameters, got 1 anyway, the variable is correctly initialized, but I get the log. Is this a bug? PS: I'm running dovecot 2.2.33 -- Angel L.

split auth from other logging
by Kai Schaetzl 02 Oct '18

02 Oct '18

Is there a way to split the auth logging (logins and failed logins) from the other logging that goes to info_log_path = /var/log/dovecot/dovecot.log ? This log gets a lot of other info as well, most notably the lmtp notifications about every filed mail (with no level stamping, btw). This makes it really hard to find authentication errors quickly and comfortably. It would be nice to be able to split at least the lmtp messages away. Kai

Released Pigeonhole v0.5.3 for Dovecot v2.3.3.
by Stephan Bosch 02 Oct '18

02 Oct '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.3. Only two insignificant memory leak fixes were added since the release candidate (not mentioned in the changelog). Changelog v0.5.3: - Fix assertion panic occurring when managesieve service fails to open INBOX while saving a Sieve script. This was caused by a lack of cleanup after failure. - Fix specific messages causing an assert panic with actions that compose a reply (e.g. vacation). With some rather weird input from the original message, the header folding algorithm (as used for composing the References header for the reply) got confused, causing the panic. - IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing. After finishing reading the Sieve script, the command parsing sometimes didn't continue with the search arguments. This is a time- critical bug that likely only occurs when the Sieve script is sent in the next TCP frame. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.3.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.3.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.3.3 rc1 - Error: sieve: !!BUG!!: Binary compiled from dovecot.sieve is still corrupt
by James 01 Oct '18

01 Oct '18

I have a sieve problem with dovecot v2.3.3 rc1 with either of pigeonhole 0.5.2 or 0.5.3.rc1. The the change that triggers this is in dovecot not pigeonhole. Sieve filtering has been working with v2.3.2 and many earlier versions. Log report: Sep 24 10:36:13 mailhost dovecot: [ID 702911 mail.error] lmtp(user(a)domain.tld)<15816><RnikKw2wqFvIPQAAs831Jw>: Error: sieve: !!BUG!!: Binary compiled from /path/to/domain/user/dovecot.sieve is still corrupt; bailing out and reverting to default delivery This is a sieve script with a vacation handler. My other sieve filters are working. My actual sieve filter worked before and was written by Roundcube web mail. My failing test script is cut-n-paste from the sieve examples https://wiki2.dovecot.org/Pigeonhole/Sieve/Examples so should not be in doubt. The text script compiles to dovecot.svbin and newly compiled files are identical to older versions, the compilation has not changed. James.

doveadm backup abort in imapc-client.c
by Evan Klitzke 01 Oct '18

01 Oct '18

I am using Dovecot 2.2.36 and I am trying to use doveadm backup to migrate email from Gmail to Dovecot. When I run doveadm backup, it goes for a while and then eventually hits an assertion error (I've tried this a few times now and it happens reliably). The assertion failure looks like this: dsync(evan(a)eklitzke.org): Panic: file imapc-client.c: line 179 (imapc_client_run_pre): assertion failed: (client->ioloop == NULL) The last few lines of log output before the crash look like this: https://gist.github.com/eklitzke/9a0dd77c44a6ee33e812f85d5773c24c The GDB backtrace when the program panics looks like this: https://gist.github.com/eklitzke/6b311474b08b546c462e0444c5cf479b The output of "dovecot --version" prints "2.2.36 (1f10bfa63)" and I'm using the version provided by Fedora's dovecot-2.2.36-1.fc28.src.rpm package. Is there any other information I can provide to assist in debugging? I could provide a core dump provided there was a way to scrub my IMAP credentials. -- Evan Klitzke pgp: 0x157EFCACBC648422 e: evan(a)eklitzke.org w: https://eklitzke.org

dsync replication
by Matt Bryant 01 Oct '18

01 Oct '18

We have a setup with ldap and sql passdbs and sql userdb, from my understanding of the documentation dsync repliction picks up the users to replicate via the iterate query. This query returns 646 users in sql (not everyone gets replicated) but when i run a doveadm replicator status Total number of known users 92236 seriously that kinda lot more than 646 Does iterate_query belong in user_db or passdb? Is it the fact I have ldap and sql passdb and its picking up dome default ldap query as well the specified sql iterate query ? rgds Matt
