`mail_crypt` Doesn't Appear to be Working
by jordan.h＠startmail.com 17 Feb '18

17 Feb '18

Dovecot version: 2.2.22 (fe789d2) I generated an EC key from the page https://wiki2.dovecot.org/Plugins/. For reference here's my /etc/dovecot/conf.d/10-mail-crypt.conf file: ---- mail_plugins = $mail_plugins mail_crypt plugin { # mail_crypt_global_private_key = </etc/dovecot/ecprivkey.pem mail_crypt_global_public_key = </etc/dovecot/ecpubkey.pem mail_crypt_save_version = 2 } ---- I saw in a previous message on this mailing list that messages can be encrypted without the private key, so it's stored elsewhere. :-) After restarting dovecot and sending myself a message I found that the message was still unencrypted. Nothing in /var/log/dovecot/*.log files or syslog indicated any problem loading the plugin (I even made some mistakes with the filename beforehand, and errors indicated it was trying to find the plugin). In case in matters dovecot was installed as part of the automated iredmail install (https://iredmail.org) I didn't modify the dovecot.conf file after installation (except for thinking I needed to add `mail_crypt` to `plugins`, then figuring I didn't). Any help is appreciated. Thank you.

Director & Master Users
by Travis Dolan 16 Feb '18

16 Feb '18

Hello, I have Director setup to proxy requests to backend servers. This works fine when using "standard" username/passwords. I am not try to enable the use of the Dovecot Master user through Director into the backend servers. a.) username is being sent as masteruser*username b.) request hits the proxy and authenticates, and then is passed to the backend servers and fails auth. - logs from proxy/Director point of view. auth: Info: passwd-file(masteruser,172.31.33.224,master,<z2eYD0Rl6P+sHyHg>): Master user logging in as devteam imap-login: Info: proxy(devteam): Login failed to backend.servers:143 (master masteruser): [AUTHENTICATIONFAILED] Authentication failed.: user=<devteam>, method=PLAIN, rip=172.31.33.224, lip=192.168.71.20, session=<z2eYD0R l6P+sHyHg> - logs from backend server point of view. imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<masterusername>, method=PLAIN, rip=192.168.71.20, lip=192.168.71.99, session=<O8QN8kNlloXAqEcU> Proxy/Director Configs (hopefully this is enough) auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/conf.d/master-user-password master = yes pass = yes } passdb { driver = static args = proxy=y nopassword=y } Please let me know if I can provide any further details. Thanks in advance.

Selective authentication mechanism
by Brian Topping 16 Feb '18

16 Feb '18

Hi all! I have been using GSSAPI authentication method for all my externally reachable endpoints for some time under the theory that they cannot be hit with a dictionary attack. Unfortunately, this means iOS devices cannot log in since they (oddly) cannot use GSSAPI. I say “oddly” because desktop Mac mail can use GSSAPI just fine and https://samuelyates.wordpress.com/2013/10/11/kerberos-single-sign-on-in-ios… goes through how to set it up for web pages. In any event, what I’m looking to do is use a filter (https://wiki.dovecot.org/ConfigFile#Filters) around the auth_mechanisms such that it will allow plain authentication when the client is on a local network or the VPN. Unfortunately, the fine print on filters says "These filters work for most of the settings, but most importantly auth settings currently only support the protocol filter”. I guess it’s kind of academic, but I thought I’d ask why this is a limitation? If there is not a profound security reason to not support this, is this a good enough use case to consider it? Thanks! Brian

ACLs, shared, public, virtual mailboxes not working
by David Mehler 15 Feb '18

15 Feb '18

Hello, I'm running Dovecot 2.2.3, and am having issues with my public folders, shared folders, and virtual/ALl folders apparently ACLs are on that list as well. I was debugging an unrelated problem with my smtp server and got the following dovecot debug log output. Below is also a doveconf -n output as well as my shared-folder definition file and my global-acls file. What I'm trying to accomplish is: 1. Have a public folder that any user on the system can put messages into and respond to. 2. Have a shared folder in which user1(a)example.com and user1(a)example2.com can exchange messages. 3. For each user on the system give them a Virtual/All folder for *all of their messages. I'd appreciate any help. As an aside if anyone sees an issue with my SSL ciphers list i'd appreciate knowing that as well, in brief I'm trying to get the most secure list, pfs, and not worrying about backware compatibility. If it's not TLS 1.2 I don't touch it. Thanks. Dave.

Segfault on selecting mailbox twice in a row
by John van der Kamp 15 Feb '18

15 Feb '18

Hi, I was doing some testing with new 2.2 changes. I’m using commit 15d5b8a from origin/master-2.2. The setup is using imapc to connect to a different imap server.

Problem with CentOS package for 2.3.0 and old dependency in systemd with clean install
by TG Servers 14 Feb '18

14 Feb '18

Hi, you definitely have a problem with the packages out of your own repo for version 2.3.0 and CentOS. And this is only if you do a clean install, meaning there was no lower dovecot version ever running on the system. If you want to 'systemctl start dovecot' it breaks with a dependency error which comes from dovecot-init.service. dovecot-init.service : [Unit] Description=One-time Dovecot init service ConditionPathExists=|!/var/lib/dovecot/ssl-parameters.dat ConditionPathExists=|!/etc/pki/dovecot/certs/dovecot.pem [Service] Type=oneshot RemainAfterExit=no ExecStart=/bin/sh -c '\ if [ ! -f /etc/pki/dovecot/certs/dovecot.pem ]; \ then\ SSLDIR=/etc/pki/dovecot/ OPENSSLCONFIG=/etc/pki/dovecot/dovecot-openssl.cnf /usr/libexec/dovecot/mkcert.sh /dev/null 2>&1;\ fi;\ if [ ! -f /var/lib/dovecot/ssl-parameters.dat ]; \ then\ /usr/libexec/dovecot/ssl-params >/dev/null 2>&1; \ fi' It wants to call /usr/libexec/dovecot/ssl-params if /var/lib/dovecot/ssl-parameters.dat (which is deprecated now as I understood) is not existing. The problem is in 2.3.0 /usr/libexec/dovecot/ssl-params is not existent anymore. This error does not occur if you for instance install 2.2.x from the base repo, start it once, and then update the version from your repo. This is because the ssl-parameters.dat was created with the old version then. But this should not be the expected behaviour I think. It should be possible to do a fresh install of 2.3.0 on a fresh system. Can you please get back to me on that? Thanks, Thomas

deny passdb match messages logged only with auth_verbose=yes
by Marco Giunta 13 Feb '18

13 Feb '18

Hi at all, using deny passwd to restrict IMAP/POP3 access (https://wiki.dovecot.org/Authentication/RestrictAccess) I get deny passdb match messages: Feb 13 16:09:33 server-02 dovecot: auth: passwd-file(USERNAME,10.10.10.46,<9hzaYRllbsCTehgu>): User found from deny passdb only with auth_verbose=yes, sets global or defined in passdb block. But if I set auth_verbose=yes, for every user not present in passwd-file, Dovecot logs: Feb 13 16:09:57 server-02 dovecot: auth: passwd-file(USERNAME,10.10.10.46,<9hzaYRllbsCTehgu>): unknown user I know that if the account does not exist in the first passdb (deny passdb), then the error occur, even if it exists in the other passdb. This is normal, but auth_verbose shouldn't be used only to " Log unsuccessful authentication attempts and the reasons why they failed." ?? Again, I'm not a programmer, but 'auth_request_log_info' function in 'https://github.com/dovecot/core/blob/release-2.2.33/src/auth/auth-request.c' seems to log events only when 'auth_verbose=yes'. Is there another way to get deny passdb match messages, without enable verbose log ?

dovecot: master: Panic: kevent() failed: Invalid argument
by Adrian Gonzalez 13 Feb '18

13 Feb '18

Hello I've been seeing these panics with dovecot 2.2.31 (and older versions) under FreeBSD about once every 2-3 months or so. I know it's been discussed here in the list, but I didn't see a definitive fix. If it's been fixed, please ignore this post (sorry!). I finally managed to observe the bug on a server that has the patch that prints out the kevent() timespec values and got: Nov 29 16:46:27 mail dovecot: master: Panic: kevent(events=74, ts=59.1000000000) failed: Invalid argument Looking through the code, the panic is triggered in io_loop_handler_run_internal(). The timeout values for the kevent() call are obtained by calling io_loop_get_wait_time(), which in turn calls timeout_get_wait_time() (both in ioloop.c). The timeout is computed by subtracting the value returned by gettimeofday() from timeout->next_run, and it looks like in very rare cases the result in tv_r->tv_usec is 1000000uS (1 second). So, it seems that if gettimeofday() returns exactly 0 microseconds, and timeout->next_run has exactly 1000000 microseconds, the kevent() call will fail (1 in 1e12 chance?). I'm not entirely sure where timeout->next_run is computed, but looking at timeout_update_next(), it adjusts the seconds only if the microseconds are greater than 1000000: (ioloop.c, line 235) if (timeout->next_run.tv_usec > 1000000) { timeout->next_run.tv_sec++; timeout->next_run.tv_usec -= 1000000; } It seems like the comparison here should be greater or equal, but I'm not familiar enough with the code to say with absolute certainty. I added more debug error messages to the code in timeout_update_next(), and although I do see next_run->tv_usec at 1000000 several times a day, I haven't seen a panic since early December on any of our servers, so I decided to post this to see if this analysis makes sense.

"search return (min)" is very inefficient
by Jesus Cea 13 Feb '18

RFC 4731: " IMAP4 Extension to SEARCH Command for Controlling What Kind of Information Is Returned" https://tools.ietf.org/html/rfc4731 I do this (telnet session): """ a select proveedores/TUHS * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 8330 EXISTS * 0 RECENT * OK [UNSEEN 6085] First unseen. * OK [UIDVALIDITY 1395814416] UIDs valid * OK [UIDNEXT 8358] Predicted next UID * OK [HIGHESTMODSEQ 3149] Highest a OK [READ-WRITE] Select completed (0.264 + 0.000 + 0.263 secs). a search return (min) since 01-Feb-2018 * ESEARCH (TAG "a") MIN 8156 a OK Search completed (59.451 + 0.000 + 59.450 secs). """ Note that it needs 59 seconds to locate the first message matching the "since" criteria. This is really slow and unusable in practice. Things are worse with bigger mailboxes, of course. Am I missing some performance trick?. I am trying to locate the first message received after a particular date. I don't use the "date" header because it can be falsified and because I care about the receiving date and not the actual sending date. I guess dovecot is scanning every message in the folder (mailbox). Wouldn't those messages be stored in ascending "received" order?. Could that be used for bisection search to locate the right message?. Could that break if I copy/move/edit messages?. Is that the reason for such a awful performance?. Suggestions?.

New mail notification
by Matthew Allen 12 Feb '18

12 Feb '18

Hi, So I'm running dovecot 1.2.17 on Mac OSX using maildir in ~/Mail. After using getmail for a while to download my POP3 email and store it in the right place it started not working so I replaced it with a python script that I wrote. All was good for a while and then I stopped getting new mail notifications in my IMAP client. If I close the connection and restart the new mail shows up as !seen but no amount of re-selecting the folder will show the new mail while the connection is active. There is no untagged responses about new mail while the client is IDLEing. The client is InScribe (http://memecode.com/inscribe.php) but I doubt it's client specific. Seems to be server related. Now the python script in question just puts the .eml file in ~/Mail/tmp and then renames it to the ~/Mail/new folder. Does it need to do something else as well to make the notifications work? There aren't any error messages in the log. Just normal login history. If you can point me in the right direction that'd be appreciated. Regards

Best mail encryption solution for per-user
by tai74＠vfemail.net 11 Feb '18

11 Feb '18

Hai, Do you have advice about Dovecot plugins for mail encryption: https://wiki2.dovecot.org/Plugins/MailCrypt https://0xacab.org/riseuplabs/trees I like NaCL based encryption but the MailCrypt plugin is better because it's maintained by Dovecot developers (is this correct?) Hard to understand MailCrypt docs so may I ask, may I provide per user encryption? I don't like global because I want every user to have different encryption based on their password. But I don't see the useful of per-folder encryption. Docs for TREES are easier to understand it will work on a per-user encryption using the user password to decrypt the needed keys. How about indexing? Does native fast Dovecot indexing must be turned off for one of these or both? Is this a big performance hit? And how to turn off indexing on a per-user basis?

LDAP userdb and dovecot LDA/LMTP - different requirements
by Franta Hanzlík 10 Feb '18

10 Feb '18

Hi, I want to use Dovecot LDA (or rather LMTP) use as local deliver with Postfix MTA. Users are in LDAP DB with structure as: dn: cn=username, ou=rank, o=myorg cn: username objectClass: Person gidNumber: uNNN uidNumber: gNNN userPassword: (somehow hashed, can only bind verification) homeDirectory: /Home/$rank/$username mailActive: 0/1 mail: usera@OneDomain mail: userb@SecDomain (not all users have 2+ addresses] uid: username groupMembership: group DN (can be multiple times for different groups) ... where: - cn = uid = expected IMAP login username (which hasn't @domain part) - user1 (and user2) isn't always same as username Now I not know, how to solve IMO diferent requirements to userdb: - LDA/LMTP need LDAP userdb unit, that can retrieve the name from an email address (ie for "usera@myDomain" returns cn/uid (as dovecot "username"). - IMAP server need LDAP userdb unit, that will have the user login (username) as the input parameter, and which returns information whether or not the user exists. Can be these different requirements solved in one userdb unit? Or is it possible to have one userdb unit for LDA/LMTP, and another one for IMAP and other Dovecot components? I have also encountered entries getting the values from LDAP userdb in the form as: user_attrs = \ =user=%{ldap:uid}, \ @mail=base(%{ldap:mailDN}), \ =uid=%{ldap:uidNumber@mail}, \ =gid=%{ldap:gidNumber@mail}, \ =home=%{ldap:rootPath@mail}/%d/%n or user_attrs = \ =home=%{ldap:homeDirectory}, \ =uid=%{ldap:uidNumber}, =gid=%{ldap:gidNumber}, =quota_rule=*:bytes=%{ldap:quotaBytes}, =namespace/default/separator=%{ldap:mailSeparator} Can anyone explain how these constructions work? And what do mean attribute notations in the form '=attr=' or '@attr=' or 'quota_rule=*:storage=100M' ? Nowhere have I found a sufficiently comprehensible description of these constructions... Help very much appreciated. Thanks, Franta Hanzlik

Dovecot 2.3.0 assertion failure on LMTP delivery
by J. Nick Koston 08 Feb '18

Hi, We are seeing a frequent assertion failure on LMTP delivery with 2.3.0. This only appears to happen on CentOS/RHEL 7.

Hi there! Since i compile my own dovecot (not using dovecot from debian), i get this error on each startup dovecot with systemd Feb 07 11:16:35 aldebaran dovecot[7455]: imap: Error: net_connect_unix(/usr/local/var/run/dovecot/stats-writer) failed: Permission denied Feb 07 11:16:35 aldebaran dovecot[7455]: imap: Error: net_connect_unix(/usr/local/var/run/dovecot/stats-writer) failed: Permission denied I can change the owner and/or permissions of the file, than it works till the next reboot. How can i set this correctly in my configs? Some googling didn't give me results for this error. jakob
