Hi all, I have an AD testsetup with auth_bind setting auth_bind_userdn = "spdev\\%Ln" I created a testuser "claasc (test)" which works fine in all ldapfilters but not for the auth_bind. the log shows everything correct just "invalid credentials" mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: auth client connected (pid=12202) mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=T6knVtc0wQB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=39873 mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: client passdb out: CONT 1 mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: client in: CONT<hidden> mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: passwd-file(claasc (test),127.0.0.1,<T6knVtc0wQB/AAAB>): cache miss mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: passwd-file(claasc (test),127.0.0.1,<T6knVtc0wQB/AAAB>): lookup: user=claasc (test) file=/etc/dovecot/passwd.postmaster mail.info: Jun 9 14:12:31 dovecot: auth: passwd-file(claasc (test),127.0.0.1,<T6knVtc0wQB/AAAB>): unknown user (given password: HubertHans99) mail.debug: Jun 9 14:12:31 dovecot: auth: Debug: ldap(claasc (test),127.0.0.1,<T6knVtc0wQB/AAAB>): cache miss mail.info: Jun 9 14:12:31 dovecot: auth: ldap(claasc (test),127.0.0.1,<T6knVtc0wQB/AAAB>): invalid credentials mail.debug: Jun 9 14:12:33 dovecot: auth: Debug: client passdb out: FAIL 1 user=claasc (test) mail.info: Jun 9 14:12:33 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 2 secs): user=<claasc (test)>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<T6knVtc0wQB/AAAB> So I guess its just a bind problem. strace output from auth process of imap login: write(26, "0-\2\1\4`(\2\1\3\4\25spdev\\claasc \$test\$\200\fHubertHans99", 47) = 47 the additional \\ in front of the brackets look strange to me and might be the reason. tested Version is 2.2.18 Greetz Matze

passwd-file extra-fields: inbox=yes
by Michael Fox 02 Aug '16

02 Aug '16

I'd like to implement the virtual plugin so that POP3 users can see emails in their own inbox and a public namespace. As I understand it, I need to set "inbox=yes" separately, depending on which service the user is using. With passwd-file flat files, this means: userdb { args = ... /path/userdb.%s } userdb.imap: set the extra fields for each user = userdb_namespace/inbox/inbox=yes userdb.pop3: set the extra fields for each user = userdb_namespace/virtual/inbox=yes But without even getting to the virtual namespace part, I'm having difficulty getting the extra fields setting to work for a regular IMAP user. Specifically: If I use the Dovecot default settings of namespace inbox, which includes inbox=yes, and do NOT include the extra_fields value shown above, then IMAP users can log in OK. But if I comment out inbox=yes within namespace inbox, and then add the extra fields to userdb.imap (as shown above), (and reload doveadm), then the IMAP user is no longer able to login. Thunderbird displays "Login to server ... failed." and I get the following in syslog (mail.err): Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp(a)email.n6mef.org): Error: user mefimp(a)email.n6mef.org: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp(a)email.n6mef.org): Error: Invalid user settings.

IMAP flags and dovecot-keywords not working as expected
by Mark Foley 01 Aug '16

01 Aug '16

I've converted most of our users from Outlook to Thunderbird. One important feature of Thunderbird is that it pays attention to the IMAP non-standard message flags via the 'tags' feature (see http://wiki2.dovecot.org/MailboxFormat/Maildir) This is important because 2 users make extensive use of Outlook categories (Tags, in Thunderbird). I found that when I set a message to the 1st Tbird tag 0 (Important), the corresponding IMAP file got an 'a' suffix. Likewise, if I manually added an 'a' suffix to an IMAP file the corresponding tag was set displayed in Thunderbird. This made it easy for me to exports Outlook Categories and set IMAP messages flags accordingly. This worked perfectly on the user I was experimenting with (me). Recently, I converted one of these Outlook 'categories' users to Thunderbird. I added the appropriate flag letters to their IMAP messages, changed their tag names in Thunderbird, and created the following dovecot-keywords file as: 0 Board_and_Committee 1 Completed 2 Health_Care_meetings 3 Notifications 4 OSHP-DAS 5 personal_or_To_Do 6 Retirement_exits 7 $label5 8 Junk 9 $Forwarded 10 $MDNSent 11 $label2 However, none of the tags show up correctly in Thunderbird. If I manually set a message to have a tag of 0, the corresponding IMAP file gets a flag of 'm', not 'a' and the following is added to the dovecot-keywords files: 12 $label1 How can I fix this? Where is "$label1" text defined? Why did Thunderbird not snag the text for '0' from the dovecot-keywords file and give the IMAP file a tag of 'a'? My current theory is that the "Default" Thunderbird Tags corresponding to IMAP flags are not changeable and if new tags are create in Tbird, they get new flag letters. That would, of course, mean that if a user changes Thunderbird tag name, they would lose all tag settings on existing message. That doesn't seem right and I hope my theory is wrong. Any insight would be appreciated. --Mark

POP3 & IMAP inbox setting for virtual
by Michael Fox 01 Aug '16

01 Aug '16

Posted Monday 7/25. Haven't seen a response. Trying again: --- This is a noobie question, so bear with me if it's not worded correctly: Primary Requirements: 1) I'd like to have two namespaces - one private/per-user, and one public (visible by all logged-in users). The public mailbox(s) would be used to distribute information to all users. 2) I'd like both POP3 and IMAP users to see both namespaces. As I understand it, this requires the use of the virtual plugin for POP3, in order to create a virtual namespace which would mix together the private and public namespaces into one mailbox. I have read: http://wiki.dovecot.org/Plugins/Virtual https://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve- spamfilter-regel-fur-pop3-nutzer/ (via Google translation) The example uses a CASE statement in the MySQL userdb query. As I understand it, this is done to set which namespace contains the inbox: the private namespace or the virtual namespace -- depending on if the user is connected via the imap or pop3 service, respectively. Question: how do I accomplish the same goal (setting the proper namespace for the inbox) when using a passwd-file style flat file userdb? Thanks, Michael

How do you setup dovecot to use a self signed cert? One server will be connected to the internet. One will be totally internal and have no runtime access to the internet. Getting the below error msg. Also, I think I have a TLS 1.0 and need a 1.2 cert?... Thank you.

migration from cyrus; seg fault at mail_namespaces_get_root_sep
by vstargben＠gmail.com 31 Jul '16

31 Jul '16

Hi all, I am currently trying to migrate from cyrus to dovecot on a new system. Though only few accounts, I decided to use the mdbox format. To convert I use cyrus2dovecot first, then I use dsync to import the mailboxes. For compatibility I set the namespace of inbox to prefix = INBOX. and separator = . (as described here: http://wiki2.dovecot.org/Migration/Cyrus http://wiki.dovecot.org/Namespaces) This works except that the clients (mutt and Thunderbird) show an additional folder/mailbox "INBOX" below the inbox. How can I fix that? Should I add a prefix during conversion and not change the namespace config? On disk, the subfolders are next to INBOX. Well, I then tried to set list = children instead of "yes" for namespace inbox. On login a segfault occurs with this setting. See the information and backtrace below.

Occasional lock timeouts on Linode VM with Dovecot Replication
by Reuben Farrelly 31 Jul '16

31 Jul '16

I've been seeing periodic entries in my dovecot logs like this: dovecot[3464]: dsync-server(kaylene): Error: Couldn't lock /home/kaylene/.dovecot-sync.lock: Timed out after 30 seconds: 3 Time(s) dovecot[3464]: dsync-server(reuben): Error: Couldn't lock /home/reuben/.dovecot-sync.lock: Timed out after 30 seconds: 1 Time(s) They occur several times per day, but don't appear to have any obvious cause and I am not aware of any problems this is causing. [They could be the cause of some reappearing UID type messages that also periodically are logged, but I can't be sure] They occur on a lightly loaded Linode VM, KVM Paravirtualised and with only local SSD disk storage. The VM is a Gentoo Linux VM running the latest kernels that Linode provide. I also saw this problem under Xen. The dovecot setup is a dsync replication between two hosts, there is about 150ms of latency between them. The host where I am seeing these messages on (lightning) is a dovecot replica of another system (thunderstorm). I am using Maildir storage. Thunderstorm sees the vast majority of the client side reads and writes and lightning just functions as a not-so-active replica. Thunderstorm is also a VM but on VMware (also on SSDs). This system has never had this problem. I've had this across many dovecot versions going back many months now so it's impossible to pinpoint when this started. I am currently running dovecot -git master-2.2 branch at the moment. I've never seen disk latency in excess of 30s on any system either so I doubt that raw IO is the cause. I don't have any settings specified in 10-mail.conf in the Mail processes section relating to locking or mmap. Has anyone else experienced this and/or any ideas about where to look next to determine the root cause? Is this a common warning to see in cloud hosted/shared environments? Reuben

Master-Master replication question
by Remko Lodder 29 Jul '16

29 Jul '16

Dear list, I have setup a master-master replication setup. My primairy MX's send email over on a DNS loadbalanced way, so DNS is doing some kind of round-robin way of sending mail to both master servers. I found out, that on one of the two machines, the email synchronisation is heavily delayed. Lets assume server A receives a mail from the MX; it synchronises almost instantly with the other server. Whenever server B receives the email, it could take up to several hours to synchronise the email, it seems that it is not detected prior. It is also interesting to see, that the mailboxes on server A (Where users login to retrieve their email via webmail/clients) are significantly smaller then the mailboxes on server B. When investigating, it seems that "older" mailboxes (or storage rather since we use mdbox) are still there on server B, which already had been removed on server A. My personal mailbox was 170MB on server A, while it was still 2.5GB on server B. (which was around that size before cleaning up the mailsboxes). I enabled debugging on the servers, and I see rather quick : "Replication requests" on server A, but when getting an email on server B, I do not see the request at all. My servers are both running the same version, same configuration (utilizing puppet), both running on ZFS and FreeBSD.

The result is: ?The identify of > server 45.56.81.181 cannot be verified. The certificate for this > server is invalid.? Well, yes, that's what you would expect. You've told your mail client to connect to "45.56.81.181", the client starts the SSL negotiation and finds the certificate is made out for "sheepsystems.com", and your mail client complains about the mismatch (a possible MITM attack). This is what you want SSL enabled system to do. Since 45.56.81.181 does not map to "sheepsystems.com" yet, you can short-circuit DNS and add a direct mapping to your Mac by adding this to /etc/hosts: 45.56.81.181 sheepsystems.com then reconfiguring your mail client to use the server "sheepsystems.com". This will appease the SSL constraint. > appear in /var/log/mail.log [2]. Don't know what this is about -- probably your Mac bailing out on authentication. Joseph Tam <jtam.home(a)gmail.com>

Client app says my chained Comodo cert is invalid
by Jerry Krinock 28 Jul '16

28 Jul '16

I’ve configured Dovecot and Postfix on a new VPS running Ubuntu 16.04, using Linode’s tutorial [1], to require authentication and SSL encryption for both POP3 and SMTP. All looks OK to me except, when my email client app (macOS Mail.app) tries to log in, it says that my cert is invalid. The trouble appears when I attempt to configure a client account in Mail.app on my Mac. For the POP server name, I enter my VPS’ “45.56.81.181", because public DNS is still pointing to my existing host. I set the account to use the Apple TLS certificate, and then click to save this new account info. Before saving, Mail.app checks my entries by attempting to log in. The result is: “The identify of server 45.56.81.181 cannot be verified. The certificate for this server is invalid.” At the same time, on my new server, some entries appear in /var/log/mail.log [2]. The certificate in question is a new PositiveSSL/Comodo cert I bought the other day. It works OK for serving web pages - I mean, on this same Mac, when I visit my under-construction site at https://45.56.81.181 in Safari or Firefox, I get the padlock icon and no warnings. Comodo gave me two two files, a “.crt” which contains my cert, and a “.ca-bundle.crt” which contains their certs. Per Dovecot documentation, I concatenated these into a “chained” file containing all 3 certs, starting with mine. In /etc/dovecot/conf.d/10-ssl.conf, I set ssl_cert = this “chained” file. I tried adding the two original cert files to macOS Keychain.app with “Always trust” but that did not help. Being new at this, I would appreciate any suggestions. My `dovecot -n` output is below [3].

Sieve vacation address problem
by Harald Leithner 27 Jul '16

27 Jul '16

Hi, it seams I have a problem with the vacation script. The problem is that the vacation answers to a address that is not listed in the sieve script. I checked the postfix master.conf which delivers to lda correct parameter. In the logfile you can see that that office(a)example.com received a message that get delivered to user(a)example.com (with the sievescipt) and to office(a)example.com (another user without script). The sieve script has the :addresses parameter only set to user(a)example.com Is something wrong with my setup? We use roundcube + sievemanage to create sieve scripts. Sievescript: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["date","relational","vacation"]; # rule:[Urlaub] if allof (currentdate :zone "+0200" :value "gt" "date" "2016-07-22",

Opportunistic quota recalc
by Tom Sommer 27 Jul '16

27 Jul '16

I'm switching quota backend to redis (from maildir++), so all my current usages are reset. I get that I can do "doveadm quota recalc -A", but it takes forever (and auth processes time out/crash). It would make much more sense to recalc the usage on login if the current usage is unset. Is there no way to do a recalc-quota-on-first-login? Thanks. -- Tom Sommer

Converting mailboxes to UTF-8
by Артем Перекресний 27 Jul '16

27 Jul '16

Is any proven routine to migrate mailboxes from mUTF-7 to UTF-8 encoding? I've try to use doveadm list/mutf7/rename but have been stuck with nested inboxes. Say I have the next structure: INBOX INBOX.жыр INBOX.жыр.ядъ encoded for FS respectively as .INBOX .INBOX.&BDYESwRA- .INBOX.&BDYESwRA-.&BE8ENARK- When I've try to rename INBOX.жыр with doveadm mailbox rename -u me -s "INBOX.&BDYESwRA-" $(doveadm mailbox mutf7 -7 "INBOX.&BDYESwRA-") I've get the next: .INBOX .INBOX.жыр .INBOX.жыр.&BE8ENARK- Sure when I've try to rename .INBOX.жыр.&BE8ENARK- I've get a message that this is not a valid mUTF7-encoded string. So that is the question.

imap & pop3 using same mailbox with virtual plugin
by Michael Fox 26 Jul '16

26 Jul '16

This is a noobie question, so bear with me if it's not worded correctly: Primary Requirements: 1) I'd like to have two namespaces - one private/per-user, and one public (visible by all logged-in users). The public mailbox would be used to distribute information to all users. 2) I'd like both POP3 and IMAP users to see both namespaces. As I understand it, this requires the use of the virtual plugin to create a virtual namespace which would mix together the private and public namespaces into one mailbox. I have read: http://wiki.dovecot.org/Plugins/Virtual https://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve- spamfilter-regel-fur-pop3-nutzer/ (via Google translation) I don't really understand the example MySQL code (too much "..." for me to follow) in the above web pages. As I understand it (and I could be very wrong), the solution relies on a MySQL query to determine which namespace should have inbox = yes -- the private namespace or the virtual namespace -- depending on if the user is an imap or pop3 user, respectively. Question 1: How would this be done on a user-by-user basis if the userdb is a passwd-file flat file? Would it be something like this? -- Userdb extra fields for IMAP User: userdb_namespace/inbox/inbox=yes -- Userdb extra fields for POP3 User: userdb_namespace/virtual/inbox=yes Question 2: If I want to allow any user to use either POP3 or IMAP, then could I do it this way? protocol imap { namespace inbox { inbox = yes } } protocol pop3 { namespace virtual { inbox = yes } } Thanks, Michael

Dovecot cannot find mailboxes
by C. Andrews Lavarre 26 Jul '16

26 Jul '16

Edgar, thank you for your help: I have solved gaining access from a client (Evolution) via IMAP to the server: I can refresh, add folders, and delete folders. But I am still confounded, as IMAP does not see any mailboxes. Neither we from the command line (telnet, openssl, login, select) nor the system can find the mailbox, despite following FindMailLocation: telnet, openssl, login, then b select inbox * 0 EXISTS * 0 RECENT and postfix fails with 2016-07-23T21:22:37.312039-04:00 lavarre postfix/error[17088]: A8DA2C1BB2: to=<andy(a)privustech.com>, orig_to=<andy>, relay But the mailboxes do exist in /var/mail/vhosts/privustech.com/andy and we point to them in /etc/dovecot/users. doveconf -n is attached. ----- Two issues are: 1. file permissions and ownership 2. virtual versus system users 1. It appears that having the correct ownership and permissions on various files is critical (of course), but those parameters must also be included in the interior of the /etc/dovecot/user. So if you change permissions you also must change that file. For example, you said: i also noticed your certificate chain is broken. http://wiki2.dovecot.org/testinstallation I worked through this link, thank you. Changing permissions for the directories /var/mail/* to root:mail ($UID:$GID = 1000:12) and then changing /etc/dovecot/users correspondingly to user(a)privustech.com :{plain}actualpassword: 1000:12 ::/var/mail/vhosts/privustech.com/user now allows a normal login. and we can create a new folder (e.g., work) and delete it. However, this is at variance with http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall which says to set the ownership to vmail:vmail ($UID:$GID = 100: 5000). Doing so breaks dovecot. 2. The various links suggest that having virtual users is preferable to setting system users. The former do not require directories under /homebut they do require a directory in the mail system, which I have provided under /var/mail/vhosts. It also turns out that for virtual users you must include the domain (andy(a)privustech.com) Making that change allowed the success reported above. But despite that, we still cannot find the mailboxes on login. Any thoughts on how to have IMAP find the mailboxes (beyond FindMailLocation, which doesn't seem to work for me) would be most appreciated. Kind regards, Andy

postconf -n display error for "remote"?
by Michael Fox 25 Jul '16

25 Jul '16

Is this a bug? I configured the following: remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes } But, when I run doveconf -n, I see: remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no } Note the repeated network prefix length (/27/27 and /24/24). Is there a way to tell for sure whether this is just a cosmetic issue or something that could cause a problem? Michael

Cannot connect to Dovecot IMAP or POP
by C. Andrews Lavarre 24 Jul '16

24 Jul '16

Hello all. Thank you for your service. Easy when you know how, but presently I do not. After literally months of research and experimentation we simply cannot log into our PAM / apache2 / postfix / dovecot pop3/imap STARTTLS email server with an ordinary email client, e.g., Evolution or Thunderbird. We can connect to the host server in a host of different ways (no pun intended)—http, https, ssh, vnc, telnet, openssl -sclient Similarly we can connect to postfix and dovecot in yet another number of ways—telnet, openssl -sclient—but cannot log in to the email server with a normal email client (either Evolution or Thunderbird) by either pop3 or imap. SSL certificates are in place, verified, and tested. Part of the problem is the many changes in all the involved operating systems and protocols (e.g., imaps and pop3s are deprecated, openSUSE has migrated to LEAP, etc.) so many of the docs from Google are no longer valid. Additionally, there simply are bugs: Leap 42.1 YAST does not work when it comes to setting up websites. Documented. But I digress. I'm sure it's something really simple, but it evades me. Research details below. Any help would be more than appreciated. Thanks in advance, Andy ======================= Configuration testing details ======================= System is: Linux openSUSE Leap 42.1 Dovecot --version 2.2.18, Postfix Version: 2.11.6-3.1 Apache2 Version: 2.4.16-9.1 Connections 1.

We can send mail and read mail in the mailbox. b. Authentication is performed by PAM: passdb { driver = pam } i. Examined PAM: A. The files /etc/pam.d/xxx, where xxx = dovecot, pop, imap, are all the same lavarre:~ # cat /etc/pam.d/xxx #%PAM-1.0 auth include common-auth account include common-account password include common-password session include common-session B. They do not resemble at all the form presented in http://wiki2.dovecot.org/PasswordDatabase/PAM passdb { driver = pam args = %s } C. Add (B.) to see if that works: No change. Comment out the original (A.): No change. Restore it. c.

And we point to them in /etc/dovecot/conf.d/10-ssl.conf as seen in the above. 6. Checked listening as it does not appear in doveconf -n: lavarre:~ # doveconf protocols listen protocols = imap pop3 lmtp listen = *, :: a. conf.d/10-master.conf ports for service xxx-login {inet_listener} are commented out. In fact, the entire file is commented out. Uncomment the listeners, restart. But no change. So undo.

Managesieve problem
by Joseph Mays 23 Jul '16

23 Jul '16

Trying to get either avelsieve or server side filters to work with managesieve. Managesieve is running but whenever avelsieve or the server settings backend try to talk to it the same thing happens. So I guess it's really a problem with something about managesieve at this point. I hit the Message Filters option, it takes a long time for it to come back, though it finally just times out and does nothing, and immediately when I click on the Message Filters link the following two messages appear in /var/log/dovecot.... 2016-07-18 17:03:02 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=108(<getpwuid() error>) egid=65534(<getgrgid() error>) missing +x perm: /, dir owned by 0:111 mode=0750) 2016-07-18 17:03:02 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=108(<getpwuid() error>) egid=65534(<getgrgid() error>) missing +x perm: /, dir owned by 0:111 mode=0750) Seems to be straightforwardly a permissions error on a directory, but I don't believe it's really the / directory, so which directory is it? Any insights on where to look would be appreciated.

Disable auth_ssl_require_client_cert for SASL
by damir 22 Jul '16

22 Jul '16

Hello! Dovecot version - 2.2.6 Postfix version - 2.10.2 OS: Mageia Linux 4 x86_64 I have configured Dovecot imaps-server on 993 port to authenticate users via private certificates: auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = no Users' database is in OpenLDAP and in dovecot-ldap.conf.ext checking of users' passwords is disabled: pass_attrs = uid=%n, mail=%n@%d, =nopassword=1 It all works fine. I have configured Postfix submission-service on 587 port to connect users via StartTLS: submission inet n - y - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_enforce_tls=yes -o smtpd_tls_req_ccert=yes -o smtpd_tls_ask_ccert=yes -o smtpd_client_restrictions=permit_tls_all_clientcerts,reject -o smtpd_recipient_restrictions=permit_tls_all_clientcerts,reject -o smtpd_helo_restrictions=permit_tls_all_clientcerts,reject It works fine. And now I have a new task: I also need Postfix to authenticate OpenLDAP-users using SASL on smtps-port 465. I need it for using on mobile devices, which don't support StartTLS. So I have configured smtps in Postfix: smtps inet n - y - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_enforce_tls=yes -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject_unauth_destination -o smtpd_helo_restrictions=permit_sasl_authenticated,reject While trying to connect to smtps, clients get an error: "Client didn't present valid SSL certificate", and this is clear. The question is: how to configure an additional auth-service in dovecot, which doesn't require private certificates and authenticates users using login/password?

Suggested improvement for antispam plugin documentation
by Ralph Seichter 21 Jul '16

21 Jul '16

Hello, I struggled a bit with getting the antispam plugin to work, because the plugin configuration in http://wiki2.dovecot.org/Plugins/Antispam is incomplete. After some twiddling, I ended up with this: # /etc/dovecot/conf.d/90-plugin.conf plugin { antispam_backend = mailtrain antispam_mail_spam = spam antispam_mail_notspam = ham antispam_mail_sendmail = /path/to/mailtrain/script antispam_spam = Junk;Spam antispam_trash = Deleted Messages;Trash } I know that the antispam plugin has not yet been officially released, but I think it might be worth updating the documentation anyway. Your thoughts? -Ralph

an e-mail client for dovecot ?
by Spyros Tsiolis 21 Jul '16

21 Jul '16

Hello all, For some years now, I've been using Thunderbird for dovecot. I am not very satisfied with t/b so I thought of using m/s outlook but then I thought that I want to distance my clients from office products. I have a newly created dovecot installation on a very small site. Three nodes, all x86 Windows 7 professional with an ubuntu v14.04 server (x86 again) running dovecot 1.2.17. The clients there use dovecot as an imap server, so they have a real-world e-mail account each and whatever they want to keep , they store by gradding-and-dropping to the imap (local / archive) account. Since I have quite some experiece with thunderbird, I know most of its shortcomings; So I thought if there's an alternative (better?) imap mail client for x86 windows 7 systems than t/b. Even better if there's an alternative client that is also supporeted under linux . Any ideas are welcome, TIA, s.t.

Absolute path in SUBSCRIPTIONS
by Miloslav Hůla 20 Jul '16

20 Jul '16

Hello, I'm using following two namespaces with Dovecot 2.2.13-12~deb8u1: namespace inbox { inbox = yes list = yes location = prefix = INBOX. # the previous Cyrus compatibility separator = . subscriptions = yes type = private ... } namespace { inbox = no list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared } For the shared namespace, the subscriptions are stored globally in '/vmail/user/%%n/Maildir/subscribtions' which is bad for me. I would like too keep subscriptions per user. I cannot set 'subscriptions = no' because I have no parent namespace. And when I set :SUBSCRIPTIONS=/vmail/user/%n/Maildir/subscriptions-shared it does not work (absolute path does not work) and it creates file in: /vmail/user/%%n/Maildir/vmail/user/%n/Maildir/subscriptions-shared instead of /vmail/user/%n/Maildir/subscriptions-shared I found, that relative path hack works: :SUBSCRIPTIONS=../../%n/Maildir/subscriptions-shared but I'm not sure it is the legitimate solution. Are there other options? Kind regards, Milo

Panic when runing "doveadm mailbox status ... vsize"
by Mark Costlow 20 Jul '16

20 Jul '16

I'm using dovecot 2.2.24 on FreeBSD 10.3. I'm working on converting users from maildir to mdbox, for the usual reasons. I have converted some test users and they generally work fine. But when I run "doveadm mailbox status" I get a Panic if I ask for the vsize field (or "all"), but other fields work fine. For example: # doveadm mailbox status -u bubbacheex3 "messages" INBOX INBOX messages=53 # doveadm mailbox status -u bubbacheex3 "guid" INBOX INBOX guid=bf976912f3748957761d0100f906a3d0 # doveadm mailbox status -u bubbacheex3 "unseen" INBOX INBOX unseen=52 # doveadm mailbox status -u bubbacheex3 "vsize" INBOX doveadm(bubbacheex3): Panic: file file-lock.c: line 269: unreached Abort trap I've only converted a few users, but they all exhibit this problem. I converted them with: dsync -u bubbacheex3 mirror maildir:/var/tmp/bubbacheex3 I have done a force-resync, which succeeds but doesn't change the behavior. I spent a little time trying to get gdb running but didn't get very far (couldn't seem to get it to find the source files once I got a few levels deep in the call stack). Before I beat my head on the gdb issue more, I thought I'd check here to see if anyone has any ideas. I didn't turn up anything in google or searching this list. Here's my "doveconf -n" output: ------------------------------------------------------ # 2.2.24 (a82c823): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.3-RELEASE-p3 amd64 ufs auth_failure_delay = 1 secs auth_mechanisms = plain login auth_winbind_helper_path = /usr/local/bin/ntlm_auth auth_worker_max_count = 60 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 100 first_valid_uid = 1000 listen = * login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_location = mdbox:/var/mail/%u:INDEX=/var/dovecot/%u mail_log_prefix = "%Us(%u): " mail_nfs_storage = yes mail_privileged_group = mail mdbox_rotate_interval = 1 days mdbox_rotate_size = 4 M mmap_disable = yes namespace { inbox = yes location = prefix = separator = . } passdb { args = session=yes dovecot driver = pam } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { mode = 0600 } user = root vsz_limit = 256 M } service imap-login { chroot = login process_limit = 128 process_min_avail = 10 service_count = 1 user = dovecot vsz_limit = 64 M } service imap { drop_priv_before_exec = no process_limit = 512 vsz_limit = 256 M } service pop3-login { chroot = login process_limit = 128 process_min_avail = 5 service_count = 1 user = dovecot vsz_limit = 64 M } service pop3 { drop_priv_before_exec = no process_limit = 512 vsz_limit = 256 M } ssl_cert = </etc/mail/certs/mail.swcp.com.pem ssl_cipher_list = ALL:!LOW:!SSLv2 ssl_key = </etc/mail/certs/mail.swcp.com.pem userdb { args = blocking=yes driver = passwd } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_max_userip_connections = 20 mail_plugin_dir = /usr/local/lib/dovecot/imap } protocol pop3 { mail_max_userip_connections = 10 mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = no pop3_lock_session = no pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_no_flag_updates = no pop3_reuse_xuidl = yes pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ mail_plugin_dir = /usr/local/lib/dovecot/lda postmaster_address = postmaster(a)swcp.com quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r sendmail_path = /usr/sbin/sendmail } ------------------------------------------------------ Thanks, Mark -- Mark Costlow | Southwest Cyberport | Fax: +1-505-232-7975 cheeks(a)swcp.com | Web: www.swcp.com | Voice: +1-505-232-7992 Mail Minder - Intelligent Push Notifications for Email on the iPhone http://mailminderapp.com/download or in the App Store

Virtual mailboxes
by Lefteris Tsintjelis 19 Jul '16

19 Jul '16

I have been banging my head to the walls for the past couple of days to make virtual mailboxes work and I finally found the problem. It seems when prefetch is used the user_query is not working at all. However, I have not found any reference to this one. http://wiki.dovecot.org/Plugins/Virtual I have tried to add the SQL statements to the password_query with prefetch but it did not work. It seems that it only works with prefetch off.

dovecot --version tarball
by Leon Kyneur 19 Jul '16

19 Jul '16

Hi, Trying to understand what the version numbers mean. I typically build from the stable tarball and then apply patches as needed.. however since 2.2.25 this hasn't been working (not sure if it worked before or never really looked closely TBH). http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz - shows GITID 7be1766 however it has commits / changes newer than this. Also the github tag for 2.2.25 is c1527e5 which doesn't match the source tarball as well. Should the source tarball and git commit hash be related? Thanks Leon

Include IMAP Junk folder to pop3 clients.

Moving Maildir folders
by Mark Foley 18 Jul '16

18 Jul '16

Our office had a user leave. Another user is taking over her duties and needs reference to the departing user's email. I've copied that entire departed user's Maildir structure to the current user: mv olduser/Maildir/.* curuser/Maildir/.olduser I did change permission and ownership on curuser/Maildir/.olduser to be the target user. I did not bring over the olduser/Maildir/dovecot* files (indexes, subscriptions, etc.) as I thought that would be bad. Nevertheless, the curuser cannot see this new olduser folder (which should be at the same level as Inbox, Junk Mail, etc.). I did manually add olduser to the curuser/Maildir/subscriptions file, but still nothing. So, what did I do wrong and how do I fix it? THX -- Mark

doveconf -n display error for "remote"
by Michael Fox 15 Jul '16

15 Jul '16

Upon further testing, it seems that the issue below may only be a display bug in doveconf. In other words, the remote filter appears to work as configured, even though it is displayed with duplicate prefix length by doveconf. Is this sufficient information to report a bug or is there some other protocol? Michael ------------------------------------------- Dovecot --version: 2.2.9 I configured the following in local.conf: remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes } But, when I run doveconf -n, I see: remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no } Note the repeated network prefix length (/27/27 and /24/24).

controlling STARTTLS by IP address
by Michael Fox 15 Jul '16

15 Jul '16

On my POP3 server, I need to be able to control the use of STARTTLS by client IP address. Specifically: * Clients on certain internal subnets (e.g., 192.168.1.0/24) must not have the option to use TLS. If the client tries to use STARTTLS, the option should be rejected. This is to satisfy US FCC rules regarding the use of encryption over certain radio frequencies. * All other internal clients (e.g., 192.168.0.0/16, but not 192.168.1.0/24) should be able to use STARTTLS if they choose to. * All external clients (0.0.0.0/0) will be required to use TLS. Is there a way to control which clients are allowed to use STARTTLS according to the client's IP address? Thanks, Michael

authentication failed: Connection lost to authentication server
by Zhang Huangbin 15 Jul '16

15 Jul '16

Dear all, I got error "authentication failed: Connection lost to authentication server", i turned on debug mode in Postfix/Dovecot, but this is the error i can get. All other errors point to sasl auth failure, what does "connection lost to authentication server" means? How can i exactly know what the problem is and how to fix it? Here's my Dovecot/Postfix configuration, with Active Directory integration. - dovecot.conf: http://pastebin.com/7T05kvmH - dovecot-ldap.conf: http://pastebin.com/DtkAg01v - Postfix main.cf: http://pastebin.com/Z9Wihmvr Dovecot/Postfix and AD are running in the same network (192.168.10.X), no firewall between them. Thanks for your help. :)

by Joseph Tam 14 Jul '16

I received a bunch of these log messages at a rate of a few thousand per hour for one of my users -- she may have max'd out her quota. The directory is a NFS directory containing mbox formatted INBOX's. Other than alleviating the space crunch, is there any particular action I need to take? Joseph Tam <jtam.home(a)gmail.com>

quota config - when is the warning messag send?
by Götz Reinicke - IT Koordinator 14 Jul '16

14 Jul '16

Hi, we run dovecot 2.2.24 and from what I see, quota management with warning message is configured currently with "noenforcing". Our individual quota limit is stored in the users ldap DN which is fetched as I see from the logs and by "doveadm quota get -u" I tried to trigger the warning mail by going over the limit on my account step by step and can see that values are counted with the command above and in thunderbird by showing the orange and than red warning symbol at the bottom for me. But the warning mail script is not triggert. How may I debug this? from 90-quota.conf: service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail # dovecot unix_listener quota-warning { user = vmail } } /usr/local/bin/quota-warning.sh is owned currently by vmail and executable by vmail. Thanks for feedback and suggestion . /Götz

Pigeonhole vs dovecot gssapi option
by Larry Rosenman 13 Jul '16

13 Jul '16

Stephan, Is there a reason you don't pick up the dovecot-config file to set additional libraries like the Kerberos libs? I'm the FreeBSD Ports Maintainer for pigeonhole, and a user filed a PR about missing the krb5 libs.

passdb {driver = shadow args = override_username=%variable}
by UNIX admin 12 Jul '16

12 Jul '16

Hello list I want to implement override_username = %variable for the "shadow" driver, so that the following works: passdb { driver = shadow args = override_username=%Ln } by "%variable", I mean "Variables" at http://wiki.dovecot.org/Variables. I've hacked up a solution with strtok(3C), but that's a hack and a possible security hole, and I'd rather not implement it. What I really want is to be able to leverage Dovecot's var_expand() call, which, looking at the code, appears to be the function responsible for %variable expansion and formatting. The relevant piece of code seems to be this excerpt in auth/passdb-shadow.c: static enum passdb_result shadow_lookup(struct auth_request *request, struct spwd **spw_r) { auth_request_log_debug(request, AUTH_SUBSYS_DB, "lookup"); *spw_r = getspnam(request->user); if (*spw_r == NULL) { auth_request_log_unknown_user(request, AUTH_SUBSYS_DB); return PASSDB_RESULT_USER_UNKNOWN; } when request->user contains 'user(a)domain.tld', I want the code to be able to process "override_username", determine that the format is %Ln so that request->user is lowercased, and everything after the "@" sign is stripped. Therefore, if this user happens to exist in the shadow file, authentication will succeed. Currently, the "shadow" driver only appears to support "args = blocking=no". Please advise.

dovecot master password without "auth_master_user_separator"
by Miguel C 12 Jul '16

12 Jul '16

Looking at the doc its sugest we can either use auth_master_user_separator to login with a master user (i.e user(a)email.com*master and the master password defined in a file or db) I'm able to use this method with a password file and works just fine, however we need to sync some imap users to another destrination that does not allow us to use this format in the "email address source" (shame) But the doc also sugests if I don't use this flag I should be able to just use the same login used in the SASL mecahnisms which is not working (testing with plain text ). Is there anything more to this? I have tried to add a username to the password file with the same master password but still doens't work :| What am I missing?

Feature Request
by Doug Hardie 12 Jul '16

12 Jul '16

I would like to request an additional optional argument for queue-id to dovecot-lda. The intended use for this argument is to include in the logging. From what I can tell, the queue-id size is not consistent between the various MTAs and so would need to be allocated dynamically when read during initialization. This element in the log messages would make it easier to find the trace of a received email. Generally I can easily get the queue-id generated by postfix (or sendmail - I use both). One grep would then give me the whole picture rather than having to dig out the message-id and doing a secondary grep to obtain the lda log messages. — Doug I find it interesting that every submission to this list results in a quick response that says moderation is required since I "am not a member". However, I am a member...

is it possible to run a post-login script in a dovecot proxy with local auth?
by Luca Lesinigo 12 Jul '16

12 Jul '16

We’re using dovecot v2.2.22, authenticating on a local database (passdb with sql driver), and then proxying the connections to the backend server returned by passdb (proxy=y and backend in “host” column). To support some legacy clients we should keep POP/IMAP-before-SMTP running for some time, but right know I don’t know how to hook up a successful authentication in the dovecot proxy. I did read from http://wiki2.dovecot.org/PostLoginScripting: “...it's not currently possible to run post-login scripts in proxies, because they're not actually logging in to the local Dovecot” Does that also holds true even if the proxy is authenticating users locally before proxying them? Failing that, any idea on how to get successful logins, other than parsing the log file? thank you, -- Luca Lesinigo
