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

I don't grok autotools, but I don't think this will solve the problem. If I understand the patch correctly, it modifies the small program used by configure to test a C99 feature. Manually compiling the small test program (with and without the changes made by the patch) will result in a successful compile, but if you compile sha1.h (line 80,81), it will fail. I've reduced the problem to this: void foo(int X[static 20]); will compile but if you remove "X", it won't. Joseph Tam <jtam.home(a)gmail.com>

a question about dovecot-sieve
by 刘莹莹 11 Jul '16

11 Jul '16

question discribe: example: > vim .dovecot.sieve require ["fileinto"]; # rule:[filter1] if anyof (header :contains "Subject" "测试邮件") { fileinto "sieve"; } when i write a mail ,give subject "这是一封测试邮件" , then server convert this subject to " SUBJECT: =?UTF-8?Q?=E8=BF=99=E6=98=AF=E4=B8=80=E5=B0=81=E6=B5=8B=E8=AF=95=E9=82=AE?= =?UTF-8?Q?=E4=BB=B6?= " the essential question is when the mail go through dovecot-sieve plugin, the sieve plugin get mail subject is "这是一封测试邮件" not "这是一封测试邮件"，there is a extra space added(which as segmentation between "=?UTF-8?Q?"). SIMPLY SAY：edit subject"这是一封测试邮件" ——>server convert "SUBJECT: =?UTF-8?Q?=E8=BF=99=E6=98=AF=E4=B8=80=E5=B0=81=E6=B5=8B=E8=AF=95=E9=82=AE?= =?UTF-8?Q?=E4=BB=B6?="——>sieve plugin get "这是一封测试邮件" The result is filter failure. is this a bug ? How can I avoid it？ thanks

Raw backtrace multiple passwords not allowed

Dovecot threading implementation
by Gabriele Bulfon 08 Jul '16

08 Jul '16

Hi, I was trying to compare avrious thread refs/references implementation, both server side and client side. While testing dovecot, it looks to me that issuing thread=references or thread=refs I get the same response, while the refs drafts says it should reverse the date ordering inside a branch. Is this correct? Does Dovecot implements references and refs with same sorting? Also, cyrus has subject grouping included in references (which is bad!). What's dovecot doing in references alg?

It may be because I have a rather old gcc (3.4.4). Editing out the "static" keyword from config.h allowed it to finish the compile. Joseph Tam <jtam.home(a)gmail.com>

Deletion of mail from Junk mailbox
by Doug Hardie 08 Jul '16

08 Jul '16

I have a pigeon sive running which directs some of my received mail to the Junk folder. That works just fine. However, a couple minutes later, it is moved to Deleted mailbox and deleted from Junk. At first I thought my client was doing that so I shut down the client and it still happens. Here are the log entries: Jul 2 00:36:31 mail dovecot: imap(doug): copy from INBOX: box=Junk, uid=10842, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:36:31 mail dovecot: imap(doug): delete: box=INBOX, uid=55719, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:39:33 mail dovecot: imap(doug): copy from Junk: box=Deleted Messages, uid=31049, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:39:33 mail dovecot: imap(doug): delete: box=Junk, uid=10842, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:50:29 mail dovecot: imap(doug): expunge: box=Junk, uid=10842, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:50:29 mail dovecot: imap(doug): expunge: box=INBOX, uid=55719, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Is this the intended way the Junk maibox is supposed to work?

Released Pigeonhole v0.4.15 for Dovecot v2.2.25.
by Stephan Bosch 08 Jul '16

08 Jul '16

Hello Dovecot users, I have completed the final release. I found a few more problems while testing this release, so a few more fixes are included. I also added a behavioral change to the vacation extension. Changelog v0.4.15: * vacation extension: The sieve_user_email setting is now used in the check for implicit delivery. - imapsieve plugin: For any mail transaction, the mailbox was opened a second time, even if no mailbox rule matched. This was unintentional, useless and caused problems when the imapsieve plugin was used with other plugins like acl. - extprograms plugin: Significantly improved error handling. No stream errors were logged. - extprograms plugin: Fixed bug in handling of result code from remote program (script service). - extprograms plugin: Connection to remote program service was not retried. - Several small fixes based on static analysis. - Fixed handling of quoted string localparts in email addresses. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.15.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.15.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

LDA autocreate/autosubscribe per namespace?
by Andreas Ntaflos 07 Jul '16

07 Jul '16

Using Dovecot 2.2.25 and Pigeonhole 0.4.14. I can provide the output of doveconf -n if needed. We use a moderately clever global Sieve script to create a read-only (using ACLs) backup/archive of all incoming and outgoing mails. Mail messages filtered this way are filed into folders in a namespace called "Backup", e.g. Backup/sent-backup/${year}/${month} and Backup/received-backup/${year}/${month}. The Sieve script in question can be found at the end of this message for reference. Now obviously we generally want mailboxes to be created automatically, so we set lda_mailbox_autocreate = yes in dovecot.conf. We also want regular mailboxes, created by our users' own Sieve scripts, to be autocreated and autosubscribed, so we also set lda_mailbox_autosubscribe = yes in dovecot.conf. But we *don't* want the Backup mailboxes to be subscribed automatically, because our users usually only need access to those when they want to restore messages accidentally deleted from their INBOX or other folders. So the idea is to keep these Backup mailboxes unsubscribed, which also saves lots of space and network traffic on the user side. When a user then wants to restore a deleted mail message they subscribe to the right Backup folder and copy the message back to their INBOX (and then unsubscribe again). Is there a way to control autocreate/autosubscribe per namespace? Currently it doesn't look that way, and lda_mailbox_autocreate/lda_mailbox_autosubscribe are valid globally. The "Backup" namespace is configured this way: namespace backup { hidden = no list = yes inbox = no location = maildir:~/Maildir-backup prefix = Backup/ separator = / type = private } This is the Sieve script in /etc/dovecot/sieve.d/before/002-backup-mails.sieve: require ["subaddress", "fileinto", "copy", "envelope", "imap4flags", "variables", "date", "mailbox" ]; if currentdate :matches "year" "*" { set "year" "${1}"; } if currentdate :matches "month" "*" { set "month" "${1}"; } # This makes use of sender_bcc_maps in Postfix if envelope :detail "to" "sent-backup" { fileinto :flags "\\Seen" "Backup/sent-backup/${year}/${month}"; stop; } # We only want to backup incoming mail if it is not marked as spam. if header :contains "X-Spam-Flag" ["YES"] { discard; stop; } else { fileinto :copy :flags "\\Seen" "Backup/received-backup/${year}/${month}"; } Thanks, Andreas

duplicated mail in users inbox only
by Tom Priebe 07 Jul '16

07 Jul '16

Hello, one of my users has the issue that some mails seem to get doubled -- but only in their inbox. The mail is bcc'd to them and the original recipient receives one copy as intended. The log shows nothing extraordinary, postfix, dovecot and sieve are certain that they received and delivered one single mail (per user). Further research showed that the doubled mails' mailbox files have the same inode, which seems inexplicable. I'm using dovecot 2.2.13 replicated over two servers (Master-Master). Duplication seems to happen regardless of the receiving server, yet still not all mails they receive with them in bcc are duplicated.

Please keep replies on-list. If you removed the compiler flag, how can you get error about compiler flag? Perhaps you need to contact package maintainer?

Configure Dovecot for GSSAPI [formerly: Looking for GSSAPI config]
by Mark Foley 06 Jul '16

06 Jul '16

After a over a year and a half struggling to get Dovecot to do either NTLM or GSSAPI authentication with Samba4 AD/DC, I believe I've finally got it! Thanks to all those in this list who helped: Jan Jurkus, Edgar Pettijohn, Gregory Sloop, Tom Talpey especially Aki Tuomi; and infinite thanks to Achim Gottinger on the SambaList for his patience in working this through with me. Although my purpose was for Dovecot to authenticate mail clients, the configuration settings needed were on the Samba side. I hope a variation of these instructions can eventually make it into: http://wiki2.dovecot.org/Authentication/Kerberos What is essentially missing from the wiki is how to set up the proper Service Principal Names and the subsequent creation of a dovecot useable kerberos keytab file. The wiki comment on "k5principals passdb" was not helpful and largely unintelligble to me. Perhaps like many of you, I have switched from Microsoft SBS and Exchange to Samaba4 and Dovecot/IMAP. The transition was completely transparent to my users, except they needed a separate password for email authentication in the absence of NTLM or GSSAPI working with Dovecot. A mild inconvenience, but I have been on a "quest" to fill that gap. This solution finally takes care of that last piece. The following describes how to create the SPNs and krb5 keytab files using Samba4 which has its own built-in (Heimdal) kerberos. The procedures are probably similar for other facilities such as setspn for Windows, but I've not used those so I won't attempt to discuss those mechanism here. You do need kerberos as the Samba built-in kerberos does not have needed commands like `klist`. My distro (Slackware 14.1) does not come with kerberos (nor, I think, does Ubuntu), but is easily found at: https://slackbuilds.org/repository/14.1/network/krb5/ Ubuntu/Debian: apt-get install krb5-config libpam-krb5 krb5-user ssh-krb5 (perhaps more) After provisioning Samba4, copy the krb5.conf template to /etc/krb5.conf. (Note: the actual docs advise symlinking: ln -sf /usr/local/samba/private/krb5.conf /etc/krb5.conf but I prefer making a copy in case I need to modify things). I've set The /etc/krb5.conf file to world readable. It's default contents are (and these do not need to be changed): [libdefaults] default_realm = HPRS.LOCAL dns_lookup_realm = false dns_lookup_kdc = true where HPRS.LOCAL is my realm, of course use your own. Now, we need a samba user in order to create the necessary SPNs (Server Principal Names): $ samba-tool user create dovecot New Password: Retype Password: User 'dovecot' created successfully Next, add the SPN(s), and create the keytab: $ samba-tool spn add imap/mail.hprs.local dovecot $ samba-tool domain exportkeytab --principal imap/mail.hprs.local /etc/dovecot/dovecot.keytab Dovecot does not do my (outgoing) SMTP serving, only (incoming) IMAP, but if it did I'd have to create another SPN for smtp: $ samba-tool spn add smtp/mail.hprs.local dovecot $ samba-tool domain exportkeytab --principal smtp/mail.hprs.local /etc/dovecot/dovecot.keytab Dovecot needs to be able to read the keytab file: $ chgrp dovecot /etc/dovecot/dovecot.keytab $ chmod g+r /etc/dovecot/dovecot.keytab my new keytab: $ klist -Kek /etc/dovecot/dovecot.keytab Keytab name: FILE:/etc/dovecot/dovecot.keytab KVNO Principal ---- -------------------------------------------------------------------------- 1 imap/mail.hprs.local(a)HPRS.LOCAL (des-cbc-crc) (0x232616c2a4fd08f7) 1 imap/mail.hprs.local(a)HPRS.LOCAL (des-cbc-md5) (0x232616c2a4fd08f7) 1 imap/mail.hprs.local(a)HPRS.LOCAL (arcfour-hmac) (0x9dae89a221dc374a39f560833352f60f) (and if I also created the spn for smtp I would also have these:) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (des-cbc-crc) (0x232616c2a4fd08f7) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (des-cbc-md5) (0x232616c2a4fd08f7) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (arcfour-hmac) (0x9dae89a221dc374a39f560833352f60f) DOVECOT SETTINGS: My version: 2.2.15 Of crucial importance is to build dovecot with GSSAPI! That is NOT one of the default settings. In the dovecot build directory: ./configure --with-gssapi=yes Other than that serious build gotcha, settings are pretty simple. Add the following 3 settings to 10-auth.conf: auth_gssapi_hostname = "$ALL" auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = plain login gssapi The auth_gssapi_hostname is supposedly not required according to some of the above-listed commentors, but my 10-auth.conf template implies differently, so it can't hurt. gssapi does not require a passdb. Use whatever userdb you want. The dovecot wiki doc has some suggestions, not of which I've tried. I use the 'driver = passwd' for my userdb for unrelated reasons. I couldn't get any of this working until I rebooted the Samba AD/DC-Dovecot server, but that just may have been me not stopping/starting Samba and Dovecot in the right sequence (or, everything happened to start working with a concurrent upgrade to Samba 4.2!). In my WIN7 and Ubuntu Thunderbird clients I selected gssapi/kerberos for the IMAP authenticate method and it works! I've even changed the test user's AD password, just to make sure. Someone please put at least the required info on creating the SPNs and krb keytab file for other poor schmucks like me. Now, if I can get NTLM figured out for the remaining Outlook users ... ! --Mark

Postfix/dovecot: user unrecognized, file permissions being misread
by C. Andrews Lavarre 06 Jul '16

Hello all. Have spent several days following the excellent tutorial: http://www.binarytides.com/install-postfix-dovecot-debian/ but still fail to have the user recognized and am getting log entries that the mail directories are 0755 when I can clearly see that they are 0774. Very puzzling, any help would be deeply appreciated. Best regards, Andy =========== Details =========== • I can add directories under IMAP, so my IMAP login and permissions must be correct. • I can create an outgoing message under IMAP, but clicking SEND just hangs. Logs do not indicate problem. • I clearly can send it a message with smtp. The message is delivered to postfix, but then dovecot fails to deliver it to a mailbox. ------------------------------------ Log Entries --------------------- --------------- # tail /var/log/mail postfix/qmgr[16390]: 9D6E8C1A77: from=<alavarre(a)gmail.com>, size=2794, nrcpt=1 (queue active) Message has been received postfix/lmtp[16770]: C218DC197D: to=<alavarre(a)privustech.com>, relay=mail.privustech.com[private/lmtp], delay=2560, delays=2260/0.01/300/0, dsn=4.4.2, status=deferred (conversation with mail.privustech.com[private/lmtp] timed out while receiving the initial server greeting) lmtp is not working ------------------------------------ # tail /var/log/dovecot.log auth-worker(16612): Info: pam(alavarre(a)privustech.com,98.179.190.111): unknown user imap-login: Info: Login: user=<alavarre(a)privustech.com>, method=PLAIN, rip=98.179.190.111, lip=70.186.159.22, mpid=16615, TLS, session=<ad;slfj;asfa;> imap(alavarre(a)privustech.com): Error: mkdir(/var/mail/vhosts/privustech.com/alavarre/cur) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/mail/vhosts/privustech.com/alavarre, dir owned by 0:0 mode=0755) However, the mail directory /var/mail/vhosts/privustech.com/alavarre is -rwxrwxr-- vmail:vmail and I have restarted both postfix and dovecot. ========================= System is openSUSE Leap 42.1 (64). postfix and dovecot with SASL authentication, connecting through a Unix socket: /etc/postfix/main.cf: virtual_transport = lmtp:unix:private/lmtp /etc/dovecot/conf.d/10-master.cf: service lmtp { unix_listener /var/spool/postfix/private/lmtp { mode = 0600 user = postfix group = postfix } The lmtp socket is owned by postfix, while the mail system is owned by vmail, per the tutorial. ------------------------------ I am using virtual users (not system users) defined in /etc/dovecot/dovecot-users: alavarre@privustech.com:{plain}ksaj;flkasjd;ds;f Thanks in advance, Andy

Hi, 2.2.25 crashes on FreeBSD with a kqueue-related message. I see references to something similar (http://www.dovecot.org/list/dovecot/2012-February.txt) from a couple years ago. I get: Jul 1 10:07:27 imap dovecot: master: Panic: kevent(EV_ADD, READ, 54) failed: Bad file descriptor It's not dumping core, and I get the message even with "protocols =" Downgrading back to 2.2.24 fixes it.

duplicate Mails with dsync replication
by Dennis Kuhn 05 Jul '16

Hi! We have some strange replication issues. Some mails are duplicated when expunged. This bug is quite hard to reproduce, it just happens occasionally. It seems somehow related to sieve. When i deleted the sieve script i could not reproduce this behavior. Here are some logs, mjm-100010(a)mydomain.com is an alias for mjm(a)mydomain.com: # Master Jun 23 00:51:41 dobby4 dovecot: lmtp(mjm-100010(a)mydomain.com): copy from <lmtp DATA>: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 00:51:41 dobby4 dovecot: lmtp(mjm-100010(a)mydomain.com): 4N23HaMVa1fpmQEAJEBNLA: sieve: msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>: stored mail into mailbox 'INBOX' Jun 23 04:52:57 dobby4 dovecot: pop3(mjm(a)mydomain.com): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby4 dovecot: dsync-local(mjm(a)mydomain.com): save: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:21 dobby4 dovecot: pop3(mjm(a)mydomain.com): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 # Replica Jun 23 00:51:42 dobby5 dovecot: dsync-server(mjm-100010(a)mydomain.com): save: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): copy from INBOX: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:22 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 The problem is the "dsync-server(mjm(a)mydomain.com): copy from INBOX: box=INBOX, uid=7817" on dobby5 at 04:52:57. This creates a new uid 7817 and the new mail is replicated back to dobby4. But i have no idea what triggers this copy. Any ideas? The dovecot version is 2.2.24. Thanks Dennis
