lmtp(------): Debug: SSL_get_servername() failed
by chayes＠afo.net 18 Mar '20

18 Mar '20

I have a smoothly running dovecot 2.3.7.2 & sendmail IMAP with SSL combo on Fedora 30. However, I see oodles of these when ssl verbosity is turned up: lmtp(25738): Debug: SSL_get_servername() failed Should I be concerned or is there a setting that stops that?

Re: Headsup on feature removal - password
by Rupert Gallagher 18 Mar '20

> Password schemes: HMAC-MD5, RPA, SKEY, PLAIN-MD4, LANMAN, NTLM, SMD5 The web is flooded with plain text passwords and hashed passwords harvested from hacked servers. Dovecot stores passwords with the same scheme used for client authentication. Therefore, we use crammd5/hmac-md5. It does not look like much, but is better than plaintext. As md5 is about to go, and I have no intention to store passwords in plaintext, I need to split the scheme used to store passwords from the scheme used for authentication, and migrate storage from md5 to bcrypt. Since this is not possible, I think I will drop passwords entirely and use certificates.

Getting autoexpunge to work
by Philip Colmer 17 Mar '20

17 Mar '20

dovecot 2.2.33.2 (d6601f4ec) on Ubuntu 18.04 The recent announcement that expunge is going to be deprecated and that autoexpunge should be used instead reminded me that my recent switch over to autoexpunge is not working. There has been an active discussion today about getting expunge working so I thought I'd use the commands suggested there to figure out why autoexpunge might not be doing anything. "doveadm search -u local-finance-support mailbox INBOX savedbefore 12w" returns nothing even though the first email for that user is dated November 12th 2019. Using the message ID for that first email, I then tried this: doveadm search -u local-finance-support HEADER MESSAGE-ID "CAHgKB_f5ttC3kLgxgZiNzwyySvUfb-NXodqZ7K3+dkHKCOUwhg(a)mail.gmail.com" f55e9737e270c2564d1a0000e171d23e 37 then doveadm fetch -u local-finance-support "mailbox date.saved" UID 37 mailbox: INBOX date.saved: 2020-03-17 14:34:12 Why on earth is dovecot showing today's date for that message? What have I misunderstood or misconfigured? Regards Philip

doveadm expunge not expunging anymore
by mabi 17 Mar '20

17 Mar '20

Hello, I have migrated my mailbox server from Dovecot 2.1.7 (Debian 7) to Dovecot 2.3.4 (Debian 10) and have a crontab setup in root to daily delete all mails in the INBOX of a specific user which are older than 90 days like this: /usr/bin/doveadm expunge -u username\(a)domain.com mailbox INBOX savedbefore 90d Unfortunately this does not work anymore. I also tried to run the command manually as root which does not return any output or errors. Any idea why this command does not work anymore? Regards, Mabi

LDAP pass_filter seems to be not working
by Balázs Zeller 16 Mar '20

16 Mar '20

Hi, we are using dovecot --version: 2.3.9.3 (9f41b88fa) with LDAP integration Just discovered the the config which was working for a while is not working now. (we are constantly upgrading dovecot). we have smtp/imap/pop3/sieveEnabled field in our LDAP directory to control which user is able to use witch services. The pass filter was used for control the usage for years now with %LsEnabled filter (see below at config dump) We just discovered that this filter is not working anymore! We not even see any pass_filter queries in LDAP. We see user_filter queries but no pass_filter queries. Did we miss something in the changelog? *LDAP configuration:* grep -v '^ *$#.*$\?$' dovecot-ldap.conf.ext uris = ldap://ldap.services/ dn = cn=administrator,dc=top dnpass = ************ debug_level = 1 auth_bind = yes auth_bind_userdn = mail=%u,ou=service_mail,dc=top ldap_version = 3 base = ou=service_mail,dc=top deref = never scope = subtree user_attrs = mailQuota=quota_rule=*:bytes=%$,mailLocation=mail user_filter = (&(objectClass=customMail)(!(mailEnabled=FALSE))(mail=%u)) pass_attrs = =user=%{ldap:mail} pass_filter = (&(objectClass=customMail)(!(mailEnabled=FALSE))(mail=%u)(%LsEnabled=TRUE)) iterate_attrs = mail=user iterate_filter = (objectClass=demonMail) default_pass_scheme = SSHA *Dovecot main config:* dovecot -n # 2.3.9.3 (9f41b88fa): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.9 (db4e9a2f) # OS: Linux 4.19.87-1.ph3-esx x86_64 xfs # Hostname: 26feef366ef9 auth_cache_negative_ttl = 1 mins auth_cache_size = 10 M auth_cache_ttl = 1 mins auth_debug = yes auth_master_user_separator = * auth_mechanisms = login plain auth_verbose = yes default_vsz_limit = 512 M disable_plaintext_auth = no doveadm_api_key = # hidden, use -P to show it first_valid_gid = 901 first_valid_uid = 901 hostname = mail.****.** imap_client_workarounds = tb-extra-mailbox-sep imapc_features = rfc822.size fetch-headers imapc_host = x.x.x.x imapc_master_user = masteruser imapc_password = # hidden, use -P to show it imapc_user = %u last_valid_gid = 901 last_valid_uid = 901 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_gid = 901 mail_home = /vmail/%d/%n/ mail_location = maildir:/vmail/%d/%n/ mail_plugins = " quota zlib trash fts fts_solr" mail_prefetch_count = 20 mail_privileged_group = mail mail_uid = 901 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 { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes } passdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } plugin { fts = solr fts_autoindex = yes fts_solr = url=http://hostname:8983/solr/dovecot/ quota = dict:user::file:/vmail/%d/%n/dovecot.quota quota_exceeded_message = The quota of the recipient is full, please try it again later sieve = /vmail/%d/%n/dovecot.sieve sieve_dir = /vmail/.sieve/%u sieve_max_redirects = 20 trash = /etc/dovecot/dovecot-trash.conf.ext zlib_save = gz zlib_save_level = 6 } pop3_client_workarounds = outlook-no-nuls postmaster_address = postmaster(a)hostname.com protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service doveadm { inet_listener http { port = 8099 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 4 service_count = 0 vsz_limit = 2 G } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service stats { unix_listener stats-reader { group = mail mode = 0666 user = } unix_listener stats-writer { group = mail mode = 0666 user = } } ssl_ca = </etc/ssl/certs/ca-certificates.crt ssl_cert = </ssl/cert.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lda { mail_plugins = " quota zlib trash fts fts_solr sieve quota zlib" } protocol imap { mail_max_userip_connections = 50 mail_plugins = " quota zlib trash fts fts_solr imap_quota zlib" } protocol pop3 { mail_plugins = " quota zlib trash fts fts_solr quota" } Regards Balazs

lmtp and recipient_delimiter
by Juri Haberland 16 Mar '20

16 Mar '20

Hi list, I have a small problem with recipient_delimiters contained in usernames. Recently I have extended recipient_delimiter from "+" to "+-" in both Postfix and Dovecot (using lmtp) and now any user that have a '-' in it's username can't receive mail anymore, because lmtp truncates the localpart after the '-' and of course can't find the first half in the user database. To illustrate: given an account "foo-bar(a)example.com", I get the following log entry from postfix: Mar 9 09:31:43 batleth postfix/lmtp[6196]: 9A7BA33E005B: to=<foo-bar(a)example.com>, relay=batleth.sapienti-sat.org[private/dovecot-lmtp], delay=20, delays=20/0.01/0.01/0.08, dsn=5.1.1, status=bounced (host batleth.sapienti-sat.org[private/dovecot-lmtp] said: 550 5.1.1 <foo-bar(a)example.com> User doesn't exist: foo(a)example.com (in reply to RCPT TO command)) Is there any way to tell lmtp to first look for <user><delimiter><extension> and if that fails look for <user> only (the reverse order would be ok, too)?

Catchall with UserDB?
by Ferenc 15 Mar '20

15 Mar '20

Hi! I've set up Postfix with virtual users. I wanted to get Dovecot and LMTP up and running with Passwd-file UserDB, which they do, but I can't figure out how to make use of a catch-all. Currently, mail to joe(a)example.com needs Joe to be in the Passwd-file. I would like anyone(a)example.com to go to Joe's mailbox, or actually mail to @example.com should go to Joe. But what do I put in the Passwd-file? I need this for several domains. Like @somedomain.org should go to jim(a)example.com and @anydomain.net to jake(a)example.com. I've googled myself silly but I cannot find the it. Everybody is hooked on a sql userdb which seems like overkill to me. With Postfix doing local delivery this is rather trivial. With Dovecot LDA I got it working by using virtual_alias_maps and the right parameters in master.cf. But with LMTP I'm stumped. cheers, Ferenc

Hi! We made a mistake of releasing pigeonhole with wrong release notes, so please find the correct release notes here. Also if you are using `--without-dovecot-install-dirs`, you must use `--with-moduledir`. Otherwise the Makefile gets broken. v0.5.10 2020-03-06 Aki Tuomi <aki.tuomi(a)open-xchange.com> * imap_sieve_filter: Change result action logging to include IMAP UID - vacation: Addresses were compared case-sensitively.

Dovecot Imap-Proxy: openssl_iostream_handle_error

how to create Drafts, Junk, Sent, Trash folders after user already created
by chayes＠afo.net 10 Mar '20

10 Mar '20

Hello Dovecot, Do to a misconfiguration, I have a bunch of users who do not have the standard folders. I can create a routine to cycle through the users and look for the folders and run a command if there is one. Is there a way to create the proper namespace for a user after the user has already been created? Thanks in advance.

Dovecot v2.3.10 Released
by Aki Tuomi 07 Mar '20

07 Mar '20

We are pleased to release v2.3.10 of Dovecot. Please find it from locations below: https://dovecot.org/releases/2.3/dovecot-2.3.10.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.10.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Aki Tuomi Open-Xchange oy --- * Disable retpoline migitations by default. These can cause severe performance regressions, so they should be only enabled when applicable. * IMAP MOVE now commits transactions in batches of 1000 mails. This helps especially with lazy_expunge when moving a lot of mails. It mainly avoids situations where multiple IMAP sessions are running the same MOVE command and duplicating the mails in the lazy_expunge folder. With this change there can still be some duplication, but the MOVE always progresses forward. Also if the MOVE fails at some point, the changes up to the last 1000 mails are still committed instead of rolled back. Note that the COPY command behavior hasn't changed, because it is required by IMAP standard to be an atomic operation. * IMAP EXPUNGE and CLOSE now expunges mails in batches of 1000 mails. This helps especially with lazy_expunge when expunging a lot of mails (e.g. millions) to make sure that the progress always moves forward even if the process is killed. * Autoexpunging now expunges mails in batches of 1000 mails. This helps especially with lazy_expunge when expunging a lot of mails (e.g. millions) to make sure that the progress always moves forward even if the process is killed. + Add tool for generating sysreport called dovecot-sysreport. This generates a bundle of information usually needed for support requests. + Add support for the new IMAP \Important SPECIAL-USE flag (RFC 8457). + Add metric { group_by } setting. This allows automatically creating new metrics based on the fields you want to group statistics by. NOTE: This feature is considered experimental and syntax is subject to change in future release. + auth: Support SCRAM-SHA-256 authentication mechanism. + imap: Support the new IMAP STATUS=SIZE extension. + Use TCP_QUICKACK to reduce latency for some TCP connections. + quota-status: Made the service more robust against erroneous use with Postfix ACL policies other than smtpd_recipient_restrictions. + Add "revision" field support to imap_id_send setting. Using "revision *" will send in IMAP ID command response the short commit hash of the Dovecot git source tree HEAD (same as in dovecot --version). + IMAP ENVELOPE includes now all addresses when there are multiple headers (From, To, Cc, etc.) The standard way of having multiple addresses is to just list them all in a single header. It's non-standard to have multiple headers. However, since MTAs allow these mails to pass through and different software may handle them in different ways, it's better from security point of view to show all the addresses. + Event filters now support using "field_name=" to match a field that doesn't exist or has an empty value. For example use "error=" to match only events that didn't fail. - acl: INBOX ACLs shouldn't apply for IMAP GETMETADATA/SETMETADATA commands. - cassandra: CASS_ERROR_SERVER_WRITE_FAILURE error should also be treated as "uncertain write failure". - dict-redis: Using quota_clone configured with dict-redis could have crashed when Redis responded slowly. - imap-hibernate: Communication trouble with imap-master leads to segfault. - imap-hibernate: Unhibernation retrying wasn't working. - imap: Fixed auth lookup privilege problem when imap process was reused and user was being un-hibernated. - Fix potential crash when copying/moving mails within the same folder. This happened only when there were a lot of fields in dovecot.index.cache. - lib-index: Recreating dovecot.index.cache file could have crashed when merging bitmask fields. - lib-index: Using public/shared folders with INDEXPVT configured to use private \Seen flags, trying to search seen/unseen in an empty folder crashes with segfault. - lib-mail: Large base64-encoded mails weren't decoded properly. This could have affected searching/indexing mails and message snippet generation. - lib-mail: Message with only quoted text could have caused message snippet to ignore its 200 character limit and return the entire message. This was added also to dovecot.index.cache file, which increased disk space and memory usage unnecessarily. v2.3.9.2 regression (previous versions cached the quoted snippet as empty). In a large mail quoted text could have become wrongly added to the snippet, possibly mixed together with non-quoted text. - lib-smtp: client could have assert-crashed if STARTTLS handshake finished earlier than usually. - lib-ssl-iostream: remove -static flag for lib-ssl-iostream linking to prevent a compile issue. - lib-storage: Mailbox synchronization may have assert-crashed in some rare situations. - lib-storage: mdbox didn't preserve date.saved with dsync. - lib: Don't require EAI_{ADDRFAMILY,NODATA}, breaks FreeBSD - master: Some services could respawn unthrottled if they crash during startup. - push-notification: Do not send push_notification_finished event if nothing was done. This happens when mail transaction is started and ended with no changes. - quota-status: Addresses with special characters in the local part caused problems in the interaction between Postfix and Dovecot. Postfix sent its own internal representation in the recipient field, while Dovecot expected a valid RFC5321 mailbox address. - submission-login: SESSION was not correctly encoded field for the XCLIENT command. Particularly, a '+' character introduced by the session ID's Base64 encoding causes problems. - submission: Fix submission_max_mail_size to work correctly on 32-bit systems. - submission: Trusted connections crashed in second connection's EHLO if submission-login { service_count } is something else than 1 (which is the default). - submission: XCLIENT command was never used in the protocol exchange with the relay MTA when submission_backend_capabilities is configured, even when the relay MTA was properly configured to accept the XCLIENT command.

Dovecot - spam training through Outlook

Updated Roadmap for Dovecot?
by Tanstaafl 06 Mar '20

06 Mar '20

Hello, Just wanted to go take a peek at the latest Roadmap for dovecot, and note that the current wiki page is flagged as obsolete: https://wiki.dovecot.org/Roadmap Is there an updated version somewhere? I'm interested in the list of new features being worked on - especially JMAP support - and a rough idea of when said features might be expected to make it into a release. Thanks!

encrypted storage on the fly using user's password without storing password on the server
by Alex Knowles 05 Mar '20

05 Mar '20

Hi all, I just joined the list. I've read through the mail-crypt plugin docs here https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ I'm still unclear (I'm not an expert) about the following: Is it possible to obtain on-the-fly encrypted storage using the user's password without the password being stored on the server? Basically a zero-knowledge solution. Theoretically this should be possible as the user provides the password when storing or retrieving emails. The above plugin docs don't make it clear for me whether it is supported. Could a kind clarify? I'd also be very grateful for a working conf as an example. Best wishes and thanks in advance, Alex.

Dovecot autoexpunge
by Philip Colmer 03 Mar '20

03 Mar '20

Following a previous suggestion I'd received to turn on autoexpunge (https://dovecot.org/pipermail/dovecot/2020-February/118281.html) I'm now trying to confirm whether or not it is doing what I expect it to do. I've set the expiration to be 12 weeks (as shown below in the config) but a lot of the mailboxes have email in them that is much older. Reading http://dovecot.2317879.n4.nabble.com/Dovecot-2-2-20-autoexpunge-td54644.html, I've tried using "doveadm search -u user mailbox INBOX savedbefore 2w" to see if it finds any email that is older than 2 weeks (just as a test) and it doesn't. If I change "savedbefore" to be "sentbefore" then it works. If "autoexpunge" is dependent on "savedbefore" working then what do I need to do to fix this? Thanks. Regards Philip Below is the output of doveconf -n: # 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) # OS: Linux 4.15.0-1041-aws x86_64 Ubuntu 18.04.3 LTS auth_username_format = %Ln auth_verbose = yes disable_plaintext_auth = no listen = 127.0.0.1 mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail mailbox_list_index = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox INBOX { autoexpunge = 12 weeks } 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 } protocols = " imap lmtp" service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl = no ssl_cert = </etc/dovecot/private/dovecot.pem ssl_client_ca_dir = /etc/ssl/certs ssl_key = # hidden, use -P to show it userdb { driver = passwd }

dovecot-lmtp dont see otherMailbox record?

Hello Postfix + LDAP , Samba as LDAP server, Dovecot virtual_transport set in postfix to dovecot-lmtp ( for autoresponder support ) Users have their email aliases in the otherMailbox record For example, account_test@example-domain user has an alias: test@exmaple-domain Query from command line works fine: postmap -q test@example-domain ldap://etc/postfix/ad_virtual_ account_test/Maildir/ (The filter in the query ad_virtual_mailbox_maps2.cf looks like this: [cut] scope = sub query_filter = (&(objectclass=person)(|(mail= result_attribute= uid result_format = %u/Maildir/ ) However, sending an email to the alias test@example-domain ends: Feb 28 12:31:40 mbox-01 postfix/lmtp[13474]: 2367A6EF: to=<test@example-domain>, relay=mbox-01[private/dovecot- delay=0.05, delays=0.02/0/0.02, dsn=5.1.1, status=bounced (host mbox-01[private/dovecot-lmtp] said: 550 5.1.1 <test@example-domain> User doesn't exist: test@example-domain (in reply to RCPT TO command)) I modified dovecot-ldap.conf.ext: I changed: user_filter = (&(objectClass=person)(uid=%u) to: user_filter = (&(objectClass=person)(|(uid=% but that didn't solve the problem. Where's the bug? Any hint?
