[Dovecot] Error: Threading lost Message ID
by Oscar A. Jara 05 Jun '13

05 Jun '13

Hello everyone, I have just put in production dovecot imap and pop3 in replacement of courier in a setup of 700 accounts aprox. Dovecot release running is 1.2.16 in a Linux CentOS 5.8. Seems like some accounts are having problems dealing with message threading, as I read lines like this one in my logs: IMAP(some_user): Error: Threading lost Message ID ...and some of those accounts cannot even list the emails. I temporarily got rid of this problem deactivating threading on those accounts but I would like to solve it. I found a patch that seams to deal with this problem at http://hg.dovecot.org/dovecot-1.2/rev/76023d59c3b2 but it would be weird that CentOS wouldn't have release a patched version of the package. Am I missing something here? Thanks in advance! __________ Information from ESET Mail Security, version of virus signature database 8412 (20130604) __________ The message was checked by ESET Mail Security. http://www.eset.com

Re: [Dovecot] dovecot and time

I found something interesting via strace. lda is writing a timestamp with utime before doign the fsync, but I'm really not a C guy, so I have no idea why that's going on via procmail and not via commandline.

[Dovecot] partionning users among backends
by Emmanuel Dreyfus 05 Jun '13

05 Jun '13

Hi I face growing load on a mailserver, and I would like to spread the load on multiple machines. I made a first attempt with dsync but got burnt with issues with mbox, therefore now I am looking for another safer approach. Partitionning users on multiple backends would address my load problem. I would have 50% of users on mail1.example.net and 50% on mail2.example.net, but I need to correctly redirect users requests, as their mail user agents only know about mail.example.net. Is dovecot able to send request to the local machine or to proxy them to another one, depending on information it would have on user mailboxes location? If it does, do we have documentation on this? -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] Bad exit status from dsync
by Jan-Frode Myklebust 05 Jun '13

05 Jun '13

I just tried to migrate one of my users from maildir to mdbox using dsync. My conversion script is checking the dsync exit code to know if the conversion goes fine or not, and surprisingly dsync returned "0" at the same time as it gave the error: Error: Failed to sync mailbox .ta\ vare\ på ... (sorry, lost the rest of the error message) Changing the folder name to mUTF7 manually made it work, but I didn't like that dsync returned success when it got this error. That breaks the failsafe logic in my conversion script. Dovecot version dovecot-ee-2.1.16.3-1, x86_64, RHEL5. Dsync command used: dsync -v -u username(a)example.net mirror maildir:/usr/local/atmail/users/u/s/username@example.net With these dovecot.conf settings: mail_home = /srv/mailstore/%256LRHu/%Ld/%Ln mail_location = mdbox:~/mdbox -jf

[Dovecot] Dovecot and time (again)
by Rick Romero 05 Jun '13

05 Jun '13

I'm rehashing/reliving my issues from 2010: http://www.dovecot.org/list/dovecot/2010-October/053528.html In short, when calling deliver from vdelivermail (or procmail), and delivering via NFS to Maildir, the timestamp on the file is GMT. If procmail or vdelivermail completely handle the email, the timestamp is CST. The server is set to CST. What's changed from the original issue? Previously was running dovecot 1.x on FreeBSD, now 2.1.7 on Debian 7. I know it's a few versions behind, but this is a deliver only server, and ChangeLog doesn't show too many fixes for lda. Of course, running the command from the command line works perfectly... So where could my problem reside? Two examples: 1st via Calling from procmail: :0 * ? test -f /usr/lib/dovecot/dovecot-lda { :0w |/usr/lib/dovecot/deliver -d $EXT@$HOST } -rw------- 1 vpopmail vchkpw 87196 Jun 5 13:43 1370439849.M812P29560.smtp101,S=87196,W=88094 2nd via Commandline: #sudo -u vpopmail cat /tmp/testmail.txt | /usr/lib/dovecot/deliver -d rick(a)havokmon.com -rw------- 1 vpopmail vchkpw 27740 Jun 5 08:46 1370440001.M421646P29846.smtp101,S=27740,W=28243 I've thrown the TZ variable in the mix as well with no resolution |/usr/bin/env -i TZ=CST /usr/lib/dovecot/deliver -d $EXT@$HOST |/usr/bin/env -i TZ=America/Chicago /usr/lib/dovecot/deliver -d $EXT@$HOST I've also set import_environment = TZ , but it doesn't seem to show in dovecot -n ... Any other thoughts? Side note - deliver behavior has changed since 1.x. I used to be able to specifiy the HOME directory, but now deliver requires the -d parameter, so I've had to setup an Auth server where I didn't have to in the past. Am I the only one who doesn't run my servers in GMT? I seem to only find my own posts when searching on this :) Rick

[Dovecot] valid folder name
by Jan-Frode Myklebust 05 Jun '13

05 Jun '13

We have a quite large user base, with lots of bad folder names because the mail folders was earlier accessible outside of dovecot. Now we're running dsync conversions from maildir to mdbox for all users, but are struggelig a bit with dsync not liking invalid folder names. Before we convert a user we try to determine if the folder names are valid, but we don't have a very good regexp for validating it. Maybe someone else knows a way to verify (and fix?) folder names that are invalid. The rules I know is: - name doesn't start with '.' or '~' (after the initial '.') - name doesn't end with '.' - the name doesn't contain '..' - the name is valid mUTF7 So, any regexp gurus that can distill those rules down to something usable? -jf -- Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems. -jwz

[Dovecot] Administrative mailbox deletions
by Alan Brown 04 Jun '13

04 Jun '13

I'm in the process of nuking a bunch of dead mailboxes after they've been migrated to other servers - but the accounts have been kept. A simple shell script takes care of most of it, BUT.... (there's always a "but" isn't there?) One user has named all his mailboxes with leading hyphens. ie: -foo -bar -bazz and "doveadm mailbox delete" doesn't like it. Does anyone have the magic sauce needed to escape the - character? Thanks in advance Alan

[Dovecot] recursive mail_location?
by Eric Abrahamsen 04 Jun '13

04 Jun '13

Forgive what may be a newby question, but I'm trying to get a new setup working, and there are many different things confusing me. I'm trying for a gnus + dovecot + mbsync arrangement, with mbsync writing to maildirs, and gnus reading from those dirs with a dovecot invocation. Fairly standard, I think. I have multiple email accounts I'm trying to sync, all of them gmail. My problem is that mbsync creates one maildir structure for each mailbox in each account. So I end up with: ~/mail ├── acc1 │ ├── INBOX │ │ ├── cur │ │ ├── new │ │ └── tmp │ └── OTHERBOX │ ├── cur │ ├── new │ └── tmp └── acc2 ├── INBOX │ ├── cur │ ├── new │ └── tmp └── OTHERBOX ├── cur ├── new └── tmp And so on, for many accounts, and many mailboxes. I believe there's something I can configure in mbsync to collapse this a little, but there's still going to be quite a bit of nesting. Gnus, meanwhile, is meant to invoke dovecot with the "-o mail_location" switch, and as far as I can tell that needs to be pointed at a maildir structure, which means I would need a separate gnus server for each mailbox in each account. Does anyone have a recommended way of handling this? Is it possible to either "flatten" the structure further, or somehow tell dovecot to recurse into directories? I don't mind having a separate gnus server for each mail account, but I'd hate to have to do one per mailbox. I'm only just getting started and haven't invested myself in any particular setup, so if the answer is "you're doing it all wrong", I would love to hear that. Thanks! Eric

[Dovecot] Configuration advice needed.
by Olivier Girard 03 Jun '13

03 Jun '13

Hello, First, thanks for this great piece of software. I'm new to dovecot and i've just converted my old courier configuration on pop/imap server side, everithing is working just fine on this side and speed gain expected was found (not enough for our busy servers :). Setup is done with 3 dovecot virtual servers load balanced with a Hardware load balancer (this part is a big point of the question). Postfix and dovecot servers use an NFS share on a NetApp for mail, Postfix servers are writting directly to inbox maildirs. Load balanced is maintaining afinity betwen client and server so i've got no problem with this for the moment. Now, i want to setup postfix (3 HW load balanced) for local delivery with LMTP on deovecot servers, and here come my questions. Afinity can't be maintained between IMAP and LMTP for a user with my load balancer so mail can be delivered on dovecot01 and read on dovecot02, from what i've read this can be an issue with indexes. I think i need to setup a director to maintain LMTP and IMAP afinity between users and servers but on imap servers i'm identifying user with their UID, and LMTP need to see emails. Does dovecot see the same user or 2 users with the same homedir? So my question is: could you point me to the right direction with this setup, do you have any advice on this config. Actual configurations: (postlogin not in real use, just a touch on (imap/pop3)_last_login) POP/IMAP server: dovecot01# doveconf -n # 2.1.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.3-RELEASE-p3 amd64 auth_cache_negative_ttl = 0 auth_cache_size = 10 M auth_mechanisms = plain login auth_verbose = yes default_client_limit = 1500 default_process_limit = 500 default_vsz_limit = 1 G disable_plaintext_auth = no dotlock_use_excl = no lock_method = dotlock mail_fsync = always mail_gid = vmail mail_location = maildir:%h/Maildir:INDEX=/mail_index%h mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " stats" mail_uid = vmail mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } user = $default_internal_user } service imap-postlogin { executable = script-login /usr/local/bin/imap-postlogin.sh user = vmail } service imap { executable = imap imap-postlogin process_limit = 1024 } service pop3-postlogin { executable = script-login /usr/local/bin/pop3-postlogin.sh user = vmail } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 } service stats { fifo_listener stats-mail { mode = 0600 user = vmail } } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_plugins = " stats imap_stats" } Postfix Test Server: %doveconf -n # 2.1.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.3-RELEASE-p3 amd64 auth_debug = yes auth_mechanisms = plain login auth_verbose = yes default_client_limit = 1500 default_process_limit = 500 default_vsz_limit = 512 M disable_plaintext_auth = no dotlock_use_excl = no lock_method = dotlock mail_fsync = always mail_gid = vmail mail_location = maildir:%h/Maildir:INDEX=/mail_index%h mail_nfs_index = yes mail_nfs_storage = yes mail_uid = vmail mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocols = lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { user = vmail } user = $default_internal_user } service imap-postlogin { executable = script-login /usr/local/bin/imap-postlogin.sh user = vmail } service imap { executable = imap imap-postlogin process_limit = 1024 } service lmtp { inet_listener lmtp { address = * :: port = 24 } process_min_avail = 20 user = vmail } service pop3-postlogin { executable = script-login /usr/local/bin/pop3-postlogin.sh user = vmail } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } File dovecot-ldap.conf.ext uris = ldap://ldap.uang dn = cn=acces-smtp, ou=access, dc=univ-angers, dc=fr dnpass = ********** base = ou=people, dc=univ-angers, dc=fr user_attrs = homeDirectory=home user_filter = (&(|(uid=%u) (mail=%u) (auaAliasEmail=%u))(|(auaStatut=etu)(auaStatut=etu-sortant)(auaStatut=perso)(auaStatut=perso-sortant))) pass_attrs = uid=user,userPassword=password pass_filter = (&(|(uid=%u) (mail=%u) (auaAliasEmail=%u)) (|(auaStatut=etu)(auaStatut=etu-sortant)(auaStatut=perso) (auaStatut=perso-sortant))) iterate_attrs = uid=user iterate_filter = (|(auaStatut=etu)(auaStatut=etu-sortant)(auaStatut=perso)(auaStatut=perso-sortant)) default_pass_scheme = MD5-CRYPT

[Dovecot] An unconstructive grumble

5 hours of configuration attempts, error after confusing error, documentation with examples that only show extracts of working configurations. I really feel like throwing in the towel with dovecot. It should not be this hard and frankly almost impossible to understand and configure for such an incedibly simple configuration. /home/vmail/domain.name/username/cur /home/vmail/domain.name/username/new /home/vmail/domain.name/username/tmp 3 virtual users. All I want is a username and password to access my email. I have to have hit every error and problem there can be. No response at all from server, unable to find password file, unable to recognise user, invalid password. God it went on and on and on for five or more hours. For such a simple config. I know this is a totally unconstructive complaint and I should be taking the time to set out a careful explanation of my problem along with errors and logfiles but I just can't be bothered. I've tried so many many configurations and options and nothing works. How can it possibly be this hard to ghet some emails off the server with simple username/password configurations. Go ahead and flame me to a crisp. -- View this message in context: http://dovecot.2317879.n4.nabble.com/An-unconstructive-grumble-tp42598.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Settings: Dovecot + NTLM + Single Sing On + Windows + Outlook or Thunderbird.
by Maria Jose Yañez Dacosta 03 Jun '13

I am following the steps listed in: http://wiki.dovecot.org/HowTo/ActiveDirectoryNtlm My goal is to have single sign-on for Microsoft Outlook applications. I working and I have some doubts since I never set up an imap server, hope I can help :). The version that I have installed is devecot 2.0.9. "dovecot -n" shows the following: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_use_winbind = yes mbox_write_locks = fcntl passdb { driver = pam } protocols = imap pop3 ssl = no userdb { args = uid=10000 gid=10000 home=/mail/%d/%n driver = static } I show what I have in /etc/samba/smb.conf [global] workgroup = EJEMPLO realm = EJEMPLO.COM.UY server string = %h (Samba %v) security = ADS password server = ad.domain.dom username map = /etc/samba/mapeousuarios map untrusted to domain = Yes syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 name resolve order = wins host bcast local master = No domain master = No dns proxy = No wins server = here active directory ip panic action = /usr/share/samba/panic-action %d winbind separator = + winbind use default domain = Yes winbind rpc only = Yes idmap config * : range = 1200-3000 idmap config * : backend = tdb [usuarios3] path = /exports/archivos-usuarios read only = No map acl inherit = Yes store dos attributes = Yes "wbinfo -g" and "wbinfo -u" work well. kinit Administrator work well also. Some steps of the configuration in dovecot.conf does not recognize: 1) "protocols = imap imaps pop3 pop3s". 2) "mechanisms = plain ntlm login". 3) "allow_all_users=yes" y "mail=maildir:/home/vmail/%d/%1Ln/%Ln:INBOX=/home/vmail/%d/%1Ln/%Ln". I'm not sure I should put in place. I also have some doubts: 1) I have to create a keytab file containing the principal for imap and pop?, as it would indicate Dovecot?. 2) That should indicate values uid y el gid? 3) I have to set something in pam? if I make "telnet localhost imap" shows the following: OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready NTLM not appears in the options. I hope I can shed some light on the subject :) Thanks and greetings. -- Maria José

Regarding your questions: Exchange 2010 and its supported (and unsupported and deviations from) IMAP standards are described on MS-STANXIMAP (MSDN). As far as I can tell, neither XLIST nor the enhanced (=extension of the standard) version of LIST is supported. Please keep in mind that this wouldn't matter very much, since most would connect to an Exchange 2010 server using either ActiveSync or MAPI/RPC. The following scenarios would definitely work: (A) your provider allows connections using ActiveSync (often referred to as "mobile" connection/access) and you're using Outlook 2013, (B) your provider allows connections using MAPI/RPC and you're using Outlook 2010. Outlook 2013 supports the extension specified in RFC 6154 and implements it using the XLIST command (as per MS-STANOIMAP), as documented in MS-STANOIMAP part 2.2.38; however, the LIST command in the same document doesn't mention the extension, so I'd assume it (Outlook 2013) doesn't necessarily support this feature using LIST as specified per RFC6154 (but only using explicitly XLIST.) Usually, any newer IMAP server supporting RFC6154 "LIST" ("XLIST") supports both the older XLIST as well as the newer LIST syntax. If it doesn't, a patch implementing this feature shouldn't be longer than a few (10 maybe?) lines of code and a few kind words to the developer team to get it into the next release of the server in question. --- http://msdn.microsoft.com/en-us/library/ee624430%28v=exchg.80%29.aspx ----------- V0061: The specification describes how to define an experimental command or any command that is not part of the specification. Microsoft Office Outlook 2007, Microsoft Outlook 2010 Outlook does not define any such commands. Microsoft Outlook 2013 Outlook 2013 implements the IMAP LIST extension specified in [RFC6154] as the XLIST command. --------------- so it may more a typical microsoft doku problem *g but however ,in fact no working trouble with dovecot SPECIAL-USE as far i remmeber to that list posting the problem whas there should get fixed was outlooks meaning of the Junk folder stuff, which is basicly done in another way by having its own antispam feature setup, so there are a few way to workaround that problem which i never tested and never will. My simple answer always is, Outlook is the client of exchange, with few stuff supporting normal internet mail ( imap etc ), dont use it with internet mail or live with its problems for notice Horde will implement Outlook 2013 complete active sync stack , so if that will happen, use active sync modus outlook 2013 with calender, abook, push mail , should no need for direct imap server con then, and it should "feel" like using exchnage ( but i think for one account only ), as horde has caldav and carddav , syncml too it can be used as middleware between many clients on many different os types i.e thunderbird lightning and k9 or native androids mail clients in exchange mode Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

[Dovecot] dovecot-lmtp does not work
by He Shiming 01 Jun '13

01 Jun '13

Dear Community, I've got a weird problem regarding lmtp setup with dovecot 2.0.19 on ubuntu 12.04.2 LTS. My reference of the configuration is at https://library.linode.com/email/postfix/postfix2.9.6-dovecot2.0.19-mysql , and my configuration is identical to it with the exception of opening the 110 pop3 port, and enabling plain text auth. Everything from imap, smtp, pop3 (including auth) works except for lmtp. I saw thousands of the following messages in /var/log/mail.log: May 31 09:05:24 postfix/lmtp[3664]: 2FD80321F4: to=<myaddress(a)me.com>, relay=none, delay=0.41, delays=0.41/0/0/0, dsn=4.4.1, status=deferred (connect to me.com[private/dovecot-lmtp]: No such file or directory) And it happens when an incoming email is received. Here's the output of configuration: root@prosp:/etc/dovecot/conf.d# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.8.4-linode50 i686 Ubuntu 12.04.2 LTS ext3 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail 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 ihave passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service imap-login { inet_listener imap { port = 0 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3 { port = 110 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } This problem has been discussed here: http://serverfault.com/questions/512219/dovecot-lmtp-does-not-exist . I've then tried switching from unix socket to inet listener, and still got the same result. I cannot get lmtp service to start. I'm also seeing no errors in the log when dovecot is restarted (see the above link for the log). I'm wondering how do I go about troubleshooting this problem? What might be the possible cause? Is it possible for dovecot to output verbose logs regarding service startups?

[Dovecot] LDA/LMTP - saving to INBOX fallback on tempfail?
by Timo Sirainen 31 May '13

31 May '13

Currently if saving to mailbox fails for any reason, the mail is saved to INBOX instead. Same if a Sieve redirect fails, the mail is saved to INBOX. I'm wondering if anyone actually prefers this behavior when the error is temporary? For example if some index file corruption was detected, the save will most likely succeed the next time it's attempted. Or if the redirect fails because the SMTP server can't be connected to at the moment. So I was thinking about changing v2.2 LDA/LMTP to simply return temporary failure instead of saving the mail to INBOX.

Check out the "slurp" plugin and let your MTA deliver mails to, say, /var/mail/<uid> . You will have no Sieve rules then, I think.

[Dovecot] Sieve/pigeonhole with Exim and Dovecot LDA
by Sebastian Arcus 30 May '13

30 May '13

I am trying to configure my Dovecot installation to provide Vacation/Out-of-the-office emails using the Sieve plugin. My setup is a little bit peculiar: Internet Internet | ^ V | Provider's POP3 server Provider's SMTP server | ^ V | -------------- getmail | my server | | V | Dovecot LDA ---> Sieve/vacation -----> Exim | V Dovecot my server --------------- Sorry for the ASCII art above - I thought it would be quicker than trying to explain. The trouble I'm having is getting the Dovecot LDA to send successfully through the local exim instance out-of-office replies back to the provider's smtp server - when receiving fresh email from the provider (through getmail). Dovecot LDA tries to send the replies - but Exim freezes them because they don't contain the sender data in the format Exim wants it. Exim can either receive sender info: 1. On the command line, after the "-f" command line switch (but only when called by root or other users passed under "trusted_users" in exim.conf). 2. In the header of the email - in the "From:" field - but only, apparently, if it was called with the "-t" switch. Full exim command line documentation here: http://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_exim_comman… I can't figure out what command line options the Dovecot LDA is using when calling exim. I also couldn't find a way to get Dovecot LDA to pass extra options to exim, when trying to send email. The exim log has the following: 2013-05-20 15:35:15 1UeRBB-0001xc-Ar Frozen (message created with -f <>) I've inspected the frozen message - and it has the correct sender in the "From:" field - but it seems that exim isn't using that, because it wasn't called with the "-t" option. In dovecot.conf, I have the following for Dovecot LDA and sieve: protocols = imap sieve protocol lda { log_path = /var/log/dovecot/dovecot-deliver.log info_log_path = /var/log/dovecot/dovecot-deliver-info.log postmaster_address = admin(a)mydomain.co.uk hostname = mydomain.co.uk mail_plugins = sieve mail_plugin_dir = /usr/lib/dovecot sendmail_path = /usr/sbin/exim } service managesieve-login { inet_listener sieve { port = 4190 } } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } Dovecot LDA is called by getmail using the vmail user - and using the same user it is trying to call exim to deliver the out-of-office replies. I'm using Dovecot 2.2.1 with pigeonhole 0.4.0. I can post the rest of dovecot.conf if it would help. I've read through the stuff at dovecot.org - but all the Dovecot LDA and exim info refers to Exim passing email to Dovecot using Dovecot LDA - not Dovecot LDA sending email out using Exim.

[Dovecot] Perfect LDAP tree

Hello everybody and Timo. I have the next problem. With LDAP tree like ou=mail | - dc=example1.com,ou=Mail | - mail=box1(a)example1.com,dc=example1.com,ou=Mail | - mail=box2(a)example1.com,dc=example1.com,ou=Mail … | - dc=example2.com,ou=Mail | - mail=box1(a)example2.com,dc=example2.com,ou=Mail | - mail=box2(a)example2.com,dc=example2.com,ou=Mail … and settings in dovecot configuration files auth_bind = yes auth_bind_userdn = mail=%u,dc=%d,ou=mail base = ou=mail user_attrs = \ =home=/var/vmail/%Ld/%Ln, \ =quota_rule=*:storage=%{ldap:mailQuota}M user_filter = (&(objectClass=mailUser)(accountStatus=active)(mail=%u)) pass_attrs = \ =user=%{ldap:mail}, \ =proxy_maybe=yes, \ =host=%{ldap:mailHost}, \ =userdb_home=/var/vmail/%Ld/%Ln, \ =userdb_quota_rule=*:storage=%{ldap:mailQuota}M pass_filter = (&(objectClass=mailUser)(accountStatus=active)(mail=%u)) iterate_attrs = mail=user iterate_filter = (&(objectClass=mailUser)(accountStatus=active)) all works fine. But my soul of perfectionist do not like this configuration because in every mailbox record duplicated information about domain: mail=box1(a)example2.com and dc=example2.com I want to set next LDAP tree ou=mail | - dc=example1.com,ou=Mail | - mail=box1,dc=example1.com,ou=Mail | - mail=box2,dc=example1.com,ou=Mail … | - dc=example2.com,ou=Mail | - mail=box1,dc=example2.com,ou=Mail | - mail=box2,dc=example2.com,ou=Mail … but I don't understand how to limit query to box1(a)example1.com in dc=example1.com,ou=mail without using base=dc=%d,ou=Clients,o=m and how to get working iterate query for all boxes to get list box1(a)example1.com box2(a)example1.com box1(a)example2.com box2(a)example2.com in some command like doveadm quota recalc -A. Is it possible? How to take it?

Re: [Dovecot] system account delivery userdb authentication

While it's often convenient to make a distinction between 'system' and 'virtual' users, Dovecot doesn't actually know the difference. It just looks users up in the passdb and userdb you have configured. This means it's perfectly straightforward to do a completely 'virtual user' setup, and then change the passdb to 'pam', which will let the users log in with their ordinary Unix password. To allow users to log in with just a username, all you need to do is make sure the users in the userdb and passdb are listed that way. Userdb passwd and passdb pam naturally are, but there's nothing to stop you using other userdbs if you want to. The only trick here is that if you're using LDA/LMTP then incoming deliveries will (or, at least, usually should) be addressed to a full email address, so you need auth_username_format to trim that back to a username. I don't know anything about Usermin, but if it is trying to set up traditional procmail filtering and vacation(1), you may be in trouble. Or, at least, you may have to give up on using Dovecot to deliver the mail and let Postfix's local(8) and procmail deliver it into maildirs themselves. If you're happy with this, this isn't a problem for Dovecot, but it might be better to go with Sieve filtering instead. Sieve is a newish mail filtering language, designed primarily to be safe (procmail has a nasty habit of letting users run arbitrary programs). Dovecot's LDA has a pretty complete sieve implementation called Pigeonhole (you may need to install it separately), which also supports a protocol called ManageSieve designed for uploading sieve scripts remotely. There are plugins for some webmail systems (and some desktop mail clients, for that matter) which let the user edit their filters in a gooey way; this includes setting up vacation messages. I use Roundcube webmail for this purpose; it also has a perfectly good PAM password- changing plugin. Ben

[Dovecot] dsync

Hi Is dovecot dsync considered an alternative to offlineimap (or others) when both distant and local are IMAP dovecot servers ? I used offlineimap for this, but somehow offlineimap got messed up (more than once, but without me able to explain how it happened). So I'm considering dsync for this purpose... Thanks! -- erik

[Dovecot] Enable IMAP only for certain users/IP
by Simone Marx :: Edinet Srl 29 May '13

29 May '13

Hi, I'm trying to config dovecot to enable IMAP protocol only for certain IPs and users. The logical steps I've followed are: 1. If a user is trying to login from an IP that I've authorized ( listed in a file) the request is authorized. 2. If not, if the user is listed in a second file the request is authorized. 3. If also this check fails the request is rejected. I'm using PAM for passdb and a passwd-file for userdb: passdb { driver = pam args = session=yes failure_show_msg=yes max_requests=16 cache_key=%u%r%l dovecot-%s } userdb { driver = passwd-file args = /etc/passwd-dovecot } In /etc/pam.d/ there are two files: dovecot-pop3 dovecot-imap dovecot-pop3: #%PAM-1.0 @include common-auth @include common-account @include common-session (for this protocol everything works fine, I don't want to limit it.) dovecot-imap: #%PAM-1.0 @include common-auth auth sufficient pam_listfile.so item=rhost sense=allow file=/etc/dovecot/imaphosts onerr=fail auth required pam_listfile.so item=user sense=allow file=/etc/dovecot/imapusers onerr=fail @include common-account @include common-session If I'm not wrong, once the user is authenticated, PAM checks if the remote IP address is in imaphosts; if it's true, it returns PAM_SUCCESS and stops the execution of the auth block, else if it's false, PAM executes the next line, verifying the presence of the username in imapusers file; if found, then return PAM_SUCCESS, else fail. If this can work, I've a problem with pam_listfile.so and IP addresses: I want to do something smarter than specifying 2^11 IP addresses instead a /21 or IP/netmask Are there alternatives for doing it better? Thanks. Sincerely, Simone Marx.

[Dovecot] Dovecot 2.1.7-7 only allow localhost access to IMAP and POP3
by Torben Schou Jensen 29 May '13

29 May '13

Recently I have upgraded my server to Debian 7. Debian have now removed uw-imapd and suggest using dovecot instead. Debian include dovecot version 2.1.7-7. On http://www.debian-administration.org/articles/275 and http://www.debian-administration.org/articles/200 I can read how to setup older version of dovecot with SquirrelMail. They recommend to use uncrypted IMAP when SquirrelMail is on same server. What I would like to support is then imap, imaps, pop3 and pop3s. imaps and pop3s for external users. imap and pop3 only open for localhost, that is SquirrelMail on same machine. With dovecot 1 you could restrict access using "imap_listen = localhost" How do I make the same restriction with localhost on dovecot 2 ??? Brgds Torben

[Dovecot] Email migration
by Romer Ventura 29 May '13

29 May '13

Hello, So I am currently running dovecot 1.2.11 on Debian 5 for our production email systems. We just deployed some new Debian 7 servers and we will be upgrading to the latest dovecot version. I've been reading the docs, but I wanted to heard some feedback on the import of all my current email into the new installation. We have 320GB worth of email. Any gotchas I should be prepared for? Any complications I should be aware of when importing all these data? Any thoughts would be appreciated.

[Dovecot] system account delivery userdb authentication
by Yann Shukor 29 May '13

29 May '13

Hi I have a remaining issue with a mail server setup. Composed of Postfix and Dovecot it is is a 'local' mail server At first I relied upon Mysql to store the various parameters, and then switched to a flat file approach I also initially set the server up to handle virtual users, but then I realized that it was destined to manage local system accounts only. So I reconfigured it accordingly Relying on system accounts for authentication means that the domain name component is absent from the username (as opposed to virtual user identifiers) This caused me some difficulty at first with roundcube, but I was able to get around it through a manual adjustment in Mysql The remaining aspect that isn't working is the delivery of emails. The entry in master.cf for dovecot looks looks this: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deli ver -d ${recipient} The problem is that the recipient equates to the users email address, which can't in fact be used for authentication purposes with system accounts. I then tried replacing recipient with user: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -d ${user} There seems to be a rights issue because I get the following error: dovecot Fatal: setgid(100(users)) failed with euid=8(mail), gid=8(mail), egid=8(mail): Operation not permitted Any ideas ? thanks yann # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.7 ext4 log_timestamp: %d-%m-%Y %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/mail/%u mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)holinice.com mail_plugins: sieve log_path: syslog_facility: mail auth default: mechanisms: plain login verbose: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: mail group: mail

[Dovecot] dovecot + virtio (9p2000.L) = errors
by epek＠gmx.net 28 May '13

28 May '13

Hi! I hope someone knows more about the issues I've encountered in: Setup: I am running dovecot 2.1.7 on Debian Wheezy in a virtual machine (kvm-style qemu-kvm: host: ubuntu 13.04/1.4.0-dfsg-1expubuntu). The mail storage is a directory on the host machine mounted via virtfs (9p2000.L) on the guest. Furthermore ISPConfig is involved in that setup, but that should not make any significant difference at that point. Problem resolved: The problem is, that similar to nfs mmap() and dotlocking seem to fail - the mmap issue could be resolved by adding: mmap_disable=yes to dovecot.conf Problem remaining: Still the following errors remain, despite dotlock_use_excl=no May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/.quotausage.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: file dict commit: file_dotlock_open(/var/vmail/mydomain/test/.quotausage) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: file_dotlock_create(/var/vmail/mydomain/test/Maildir/dovecot-uidlist) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: file_dotlock_create(/var/vmail/mydomain/test/Maildir/dovecot-uidlist) failed: No such file or directory The "failed" files are existing on that path - permissions for the configured "vmail" user and group exist (0600).

[Dovecot] UIDLs problem on migration to dovecot
by Oscar A. Jara 27 May '13

27 May '13

Hello list, I'm about to migrate from Courier 4.6 (POP and IMAP) to Dovecot 1.2. I am currently trying to match UIDLs of both servers to avoid redownload of mails but I could not success. I've already configured dovecot POP3 to format UIDLs like this: pop3_uidl_format = UID%u-%v I also executed the script 'courier-dovecot-migrate.pl' to do the migration in a couple of test accounts but the IDs don't match for all mails and the script didn't report any errors. I have production courier pop3 server running on port 110 and the new dovecot server running on another port. Here I paste some of the missmatches in one of the test accounts: 8827 UID9060-1259354075 | 8827 UID9041-1259354075 8828 UID9061-1259354075 | 8828 UID9023-1259354075 8829 UID9062-1259354075 | 8829 UID9067-1259354075 8830 UID9063-1259354075 | 8830 UID9064-1259354075 8831 UID9064-1259354075 | 8831 UID9043-1259354075 8832 UID9065-1259354075 | 8832 UID9061-1259354075 8833 UID9066-1259354075 | 8833 UID9025-1259354075 8834 UID9067-1259354075 | 8834 UID9047-1259354075 One thing that I don't know if is important is that I am using dovecot-lda since long ago, not courier lda. I don't know what I am missing here and I would appreciate some help.

[Dovecot] Problem with dsync replication : mails are not deleted correctly
by Nicolas ROCHE 27 May '13

27 May '13

Hello, I would like to configure a postfix / dovecot cluster based on ssh / dsync replication. I have two linux serveurs (Oracle RHEL 5 86_64) and I install both sides dovecot (V2.2.2+), postfix (2.10.0) and mysql (Ver 14.12 Distrib 5.0.77). I configured these servers in order to make them replicate, and I created some virtual users. I use some java code in order to send mail (with SMTP) and to get mail (with POP3). When the java code get a mail, it deletes it from mailbox (the flag "DELETED" is set to true). When I send a mail on server A, I can see the mail replicated on both servers A and B : a file containing the message data exists in /home/vmail/test03/new/ in both sides. When I get the mail from server A with my java POP3 client, all is OK : the mail is deleted on both servers A and B (no more file in /home/vmail/test03/new/). The problem is when I send a mail on server A and I get it from server B : I can get the mail, but the mail is not deleted from server B, and neither from server A. When I try a second time to get the mail on server B, then all becomes OK : the mail is deleted on both server A and B. I can reproduce the problem every time. Is it a known bug or not ? If yes, is there a patch ? If no, may the problem come from my config ? Regards, Nicolas.

[Dovecot] Upgrading 1.2 to 2.x
by Simon B 27 May '13

27 May '13

Hi In an unscheduled maintenance window next week, I will have the opportunity to upgrade to 2.x should I wish to do and provided I can get it working on stage first. My questions: I've seen a lot on the list about the rock-solidness of 1.2 but also some people saying that some versions of 2.x better than others. Is there a recommended version - I don't need bleeding edge, I'd prefer stability, or one most of you can agree on? What am I missing by not upgrading? A few months ago I tried to convert a Dovecot 1.2 config into 2.1 and wasn't very successful. Any tips on how to go about it? Thanks. Simon

[Dovecot] mixing virtual and system users
by Julien Beauviala 27 May '13

27 May '13

Hello all, I'm setting up a small mail server for aprox 20 users, and I'm trying to keep it really simple so I went the virtual users as text file way, following this page : http://lukas-schulze.de/2012/02/setup-postfix-and-dovecot-on-debian-squeeze… It seemed to work fine except for the 'system' users, and I am stumped by this. Basically the config does not 'see' /etc/aliases, so mail to root or mailman are 'Recipient address rejected: User unknown'. I've added the backup pam as explained by the following page* and tried many permutations in /etc/postfix/main.cf but still not good, systems users are rejected. Obviously something is amiss. * http://wiki2.dovecot.org/Authentication/MultipleDatabases If someone could point me in the right direction, that would be great.

[Dovecot] Problems with Apple Mail: Enter Password for Account "..."
by Frank Röhm 26 May '13

26 May '13

Hello I have on Ubuntu 12.04 a postfix 2.9.3-2 mailserver with dovecot 2.0.19 I get email from my pc (thunderbird), my smartphone (k9mail) and my MacBook (Apple Mail 4.6 - 1085 on Mac OS 10.6.8) all with IMAP and SSL. All is working normally but sometimes I get an error message from my MacBook, which is irritating. It says this (more or less): "Enter Password for Account "..." The IMAP-Server "..." rejected the password for user "..." Enter your password again or cancel. ... o Remember this password in my keychain" The password was NOT wrong, but anyway, if reenter it, Apple Mail won't accept it, the message will come again and again. I guess that dovecot blocks apple mail maybe because the other two clients try to login at the same time? Is there any setting where I could adjust this blocking (if it is blocking) in dovecot? Only if this really is the reason. The issue is coming not regularily but when it comes, often for half an hour I cannot check mails for this account (other accounts on apple mail won't be touched). If I restart Apple Mail, the problem could be fixed, but maybe not. In the logfiles of Dovecot I don't find anything about this. Thank you and kind regards frank

[Dovecot] dovecot-sieve (pigeonhole) -- is is possible to "re-filter" INBOX when filters have been updated?
by Lev Serebryakov 25 May '13

25 May '13

Hello, Dovecot. I want to migrate to webmail (roundcube) over dovecot + sieve (pigeonhole). Now I'm using on-client (The Bat!) filters, but I need to have acccess to my mail everywhere, not only on my workstation. And I wonder, is here simple way to re-filter INBOX after sieve filters have been changed? Any offline (desktop) mail client could run new filters on old messages -- is here any way to do this with dovecot-sieve (pigeonhole)? I'm using postfix + dovecot LMTP to run sieve filters. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Virtual Servers, or different authentication setups.
by Joshua Gardner 25 May '13

25 May '13

I want to know if there is any virtual server functionality in Dovecot? I would like to have two separate configurations, that access the same email, running in the same Dovecot instance. They would bind different ports and/or IPs, but have different authentication settings. In particular, one would use a PLAIN password scheme, the other SSHA. How would I go about setting up these virtual servers? Or, would I have to run separate instances of Dovecot? If I do have to run separate instances, how do I keep them from interfering with eachother? -Josh

[Dovecot] Passwordless auth?

Hey all, I'm in the process of writing some scripts which I want to be able to take actions on my local mailbox. (For example, to move a subset of messages to the trash over time, if unread for a week. To act on messages in my learn-spam folder and then delete them). What occured to me as being a Neat Idea is if Dovecot could honor ident (rfc1413) lookups, from trusted hosts (i.e. 127.0.0.1). In this way I get all the benefits of dovecot's indexing being updated and nice locking, but I don't have to leave my password laying around in a plaintext file. (Yes, this assumes I'm running a shell on the mail server. I'm not concerned about the same level of security when you could simply cat my mail spool). I'd definitely consider something like an SSH key with a forced command (I do see questions in the FAQ about making dovecot work over a socket connection), but that forgoes using standard imap clients. I could also create a dovecot-only user with my UID and no other login privileges, but I'd like this to "just work" for anyone. I don't know anything about if dovecot supports X509 auth, but this would require the client libraries to support such a thing, which not all do. I'd love to hear about any other ways people have thought about to do this. Any ideas? -Dan Mahoney -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------

[Dovecot] userdb section order seems important in config file
by Ken A 24 May '13

24 May '13

Hi Timo, et al, I'm using Dovecot 2.2.2, with dict file based quota and a quota_rule in dovecot.conf. I have userdb configured like so: userdb { driver = passwd-file args = /etc/dovecot/passwd-file } userdb { driver = passwd } I get the behavior I want with a single line in the passwd-file for any users that I'd like to override the default quota. BUT, if I list the userdb sections in the reverse order, with the driver=passwd first, then the quotas in passwd-file are ignored. I have a feeling I am counting on undocumented behavior that might change in the future. Or is this okay to depend on? Thanks, Ken -- Ken Anderson Pacific Internet - http://www.pacific.net

[Dovecot] Is it possible to palce "detailed" (with local+folder@domai.com) messages not to INBOX/folder, but to INBOX/FixedSubfolder/folder?
by Lev Serebryakov 24 May '13

24 May '13

Hello, Dovecot. Now, with enabled "recipient_delimiter = +", "lmtp_save_to_detail_mailbox" and using LMTP, messages with "detail" in address, are placed in auto-created mailboxes. It is great, but what if I want to put all such mailboxes not in inbox directly, but lower in mailbox hierarchy? Is it possible without using sieve? -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] problem with proxy setup
by Claus 23 May '13

23 May '13

Hi all, i have some troubles in the implementation of my proxyconfiguration. i have two kind of users, the first will be proxied to a dovecot backend with masteruser-login, the other one will be proxied to another non-dovecot imapserver with nopassword. Everything looks to work if i use passwd-file like this: user1:{PLAIN}pass1:::::::proxy=y host=192.168.1.1 destuser=user1*masteruser pass=masterpass user2::::::::nopassword proxy=y host=192.168.2.2 In an second step i try the same behavior with sql (postgresql), but there are my problems. In my thinking, the sql query should return the right fields (in passwd-file) like proxy, host, .. but whats the trick, to get only the correct fields i need for the different funktions? first proxy, host, destuser, pass and on the other side nopassword, proxy and host. Maybe i have mistakes in reasoning, but in sql i get in one query always the same fields. I hope someone can give me some hints an tricks. thanks, Claus

[Dovecot] should dovecot store maildir files with CRLF or LF?
by Christoph Anton Mitterer 22 May '13

22 May '13

Hi. I've made a strange observation. When having Dovecot (at least) with maildir and moving (via IMAP) mail received by some client (Evolution 3.4) into it the following happens: Regardless of whether the mail was originally(!) set with CRLF or LF (i.e. when I use netcat to submit the plain SMTP to the relaying MTA). When the client (Evolution) had received the mail via POP3 before moving it via IMAP into Dovecot... then the maildir file within dovecot is all LF. When the client however received it via IMAP, before in turn moving it on via IMAP into Dovecot, then the maildir file is mixed CRLF and LF, i.e. the body is CRLF, the headers are terminated... Well the actually bug here is probably in Evolution (as so many others... o.O)... but I wondered... what is Dovecot expected to write files? Platform end-of-line markers (i.e. LF in case of UNIX) or always network end-of-line markers (CRLF)? Cheers, Chris.

[Dovecot] ACLs - creating new top level folders
by Ingo Rogalsky 22 May '13

22 May '13

Hi, I'm wondering, whether it's possible, to define an ACL on the mailbox itself. We use Dovecot 1.2.15 (included in Debian 6) and maildir filesystem layout: /home/mail01/user1/Maildir/new \ /home/mail01/user1/Maildir/cur Inbox /home/mail01/user1/Maildir/tmp / /home/mail01/user1/Maildir/.folder1/new \ /home/mail01/user1/Maildir/.folder1/cur folder1 /home/mail01/user1/Maildir/.folder1/tmp / ... Assigning an ACL with full access rights for user2 to the folder Inbox works as expected. user2 can create subfolders of Inbox, too. But he can't create a new folder like folder1 parallel to Inbox. Is there a possibility of defining an ACL on the mailbox of user1 itself? Or do we need to create all subfolders beneath Inbox like this is usual with other IMAP servers?

[Dovecot] dsync-2.2.2 incorrectly synchronizes subscription status of deleted mailbox
by Karol Jurak 22 May '13

22 May '13

Hi, It seems that dsync-2.2.2 doesn't correctly synchronize subscription status of a deleted mailbox. The situation is as follows. There are two servers: A and B, and a test user test_mdbox. Mailboxes (mdbox) of this user on both servers are synchronized. Specifically on both of them there is a Trash/x mailbox. Replication plugin is disabled. I delete Thrash/x mailbox on A with Thunderbird. The relevant IMAP commands issued are: 71 87.068176 10.4.0.13 10.1.107.144 IMAP Request: 9 delete "Trash/x" 72 87.072238 10.1.107.144 10.4.0.13 IMAP Response: 9 OK Delete completed. 73 87.073736 10.4.0.13 10.1.107.144 IMAP Request: 10 unsubscribe "Trash/x" 74 87.085263 10.1.107.144 10.4.0.13 IMAP Response: 10 OK Unsubscribe completed. Inspecting output of 'doveadm mailbox list' and contents of subscriptions file shows that everything is as expected, ie. mailbox was deleted and unsubscribed. Moreover in dovecot.mailbox.log on A the following records appear: #480: delete-mailbox 3f3eb117a51c9a51d8280000f671379f (2013-05-20 14:54:40) #504: delete-dir f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:54:40) #528: unsubscribe f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:54:40) Subsequently I run 'doveadm sync -u test_mdbox -d'. It causes an entry for Thrash/x to reappear in subscriptions file on both servers and the following records are appended to dovecot.mailbox.log on B: #2112: delete-mailbox 3f3eb117a51c9a51d8280000f671379f (2013-05-20 14:55:49) #2136: delete-dir f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:55:49) On A this record is added: #552: subscribe f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:55:49) So, in described situation, dsync subscribes a mailbox on a server it was deleted on instead of unsubscribing it on the other one. -- Karol Jurak

[Dovecot] Dovecot 2.2.1 LDA and sieve (lack of) errors
by Jim McNamara 21 May '13

21 May '13

Hello again, all. Of course after posting yesterday that all was well with my setup, turns out all is not well. The problem I'm having is with dovecot-lda functioning and making deliveries to my mailbox, but the sieve scripts don't seem to have any effect. Attempts at logging what is/isn't happening have been total failures. Managesieve seems to work fine, port 4190 is open on the server and it allows the tunderbird plugin to function, I can create and edit scripts with the plugin. For some reason it doesn't seem to auto-compile the scripts to binary form, but if I just need to do that manually I can live with it. I only mention the lack of auto-compiling in case that sheds light on what is wrong with the LDA or sieve. I'm running the current dovecot, 2.2.1 along with pigeonhole 0.4.0. Here is the config: root@hostname:/usr/local/dovecot-2.2.1# doveconf -n # 2.2.1: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 auth_cache_size = 10 M auth_default_realm = mail.domain.com auth_mechanisms = plain login auth_socket_path = /usr/local/var/run/dovecot/auth-userdb debug_log_path = /dev/stderr default_internal_user = vpopmail default_login_user = vpopmail first_valid_gid = 89 first_valid_uid = 89 hostname = mail.domain.com last_valid_gid = 89 last_valid_uid = 89 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /dev/stderr mail_access_groups = 89 mail_debug = yes mail_gid = 89 mail_location = maildir:%h/Maildir mail_plugins = " quota" mail_privileged_group = 89 mail_uid = 89 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 ihave spamtest spamtestplus vnd.dovecot.debug namespace inbox { inbox = yes location = prefix = separator = . } passdb { driver = vpopmail } plugin { quota = maildir:User quota quota_rule = *:storage=2G quota_warning = storage=95%% quota-warning 95 %u sieve = ~/.sieve/dovecot.sieve sieve_dir = ~/.sieve sieve_extensions = +spamtest +spamtestplus +relational +comparator-i;ascii-numeric +vnd.dovecot.debug } postmaster_address = postmaster(a)mail.domain.com protocols = imap pop3 lmtp sieve sendmail_path = /var/qmail/bin/sendmail service auth-worker { user = $default_internal_user } service auth { unix_listener auth-userdb { group = vchkpw mode = 0600 user = vpopmail } user = $default_internal_user } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 vsz_limit = 64 M } ssl = required ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.priv userdb { args = quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol lda { info_log_path = /dev/stderr log_path = /dev/stderr mail_plugins = " quota sieve" } protocol imap { mail_plugins = " quota imap_quota" } protocol pop3 { mail_plugins = " quota quota" } I've set the lda specific logs to /dev/stderr because I'm running dovecot through daemontools, and that is what it logs.

Re: [Dovecot] Outlook 2013 - mounting folders with XLIST
by Hajo Locke 21 May '13

21 May '13

Hello, >> i do some tests with dovecot 2.1.7 and activated a default special-use >> config. To get it work with outlook 2013, i also added XLIST to imap >> capability string. basically this is working. >> >> is somebody also using special-use folders successful with outlook 2013? > yes, testet a few times, works fine, without Junk folder , cause > outlook wants this handled by it own, but i ve seen reg patches to > change this My serverside setup now is completed. I did a lot of tests last weeks and experienced some strange behaviour of some clients. Outlook 2013 is only working when adding XLIST manually to imap_capability imap_capability = +XLIST This is because outlook 2013 not supports rfc 6154 but the deprecated XLIST standard invented by google. So the problem with junkfolder is not a bug in Outlook 2013, in rfc 6154 spamfolder is tagged by \Junk, in XLIST standard \Spam is used. I did see that when using a gmailaccount in outlook 2013. Adding XLIST capability to dovecot seems to be a problem for other Clients. k9 is able to work with rfc 6154 servers. But if k9 finds XLIST and SPECIAL-USE together in capabilitystring it seems to prefer XLIST requests. Because of dovecot is accepting XLIST requests, but outputs rfc 6154 details, k9 seems to be confused and dont finds special Folders. rfc 6154 is similar but not identical to XLIST. If you dont test with really individual foldernames, you get tricked by clients behaviour. I looked around and the most imap-servers of hosting companies etc. provide XLIST feature, Special-USE unfortunately only a few. So i did now some changes to dovecot sources on my own. I added \Spam as allowed special-use attribute and created a new function for XLIST Requests. So if XLIST is requested, Clients gets lines of output with XLIST and \Junk is replaced with \Spam. So all is done in the code and i dont need to change my userdb-config. Testing this server with different clients was successful. All of them did find their special folders and worked fine, outlook 2013 also finds spamfolder now. So this changes contribute to consolidate a deprecated standard but i have to find a way where all users can benefit from new features. This is not a request to change something in dovecot, this is a call to decision makers to support one rfc Standard. Hajo

[Dovecot] Configure dovecot to provide SASL authentication
by Peter Skensved 21 May '13

21 May '13

Hi, I'm trying to get dovecot to provide SASL authentication for postfix My setup appears to be working but I'm not 100% certain I've got it right. I've come across several examples for dovecot version 1 but I'm running 2.0.9. The output of doveconf -n is here : 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.2.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mbox_write_locks = fcntl passdb { driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } Specifically : are the "service auth", userdb and passdb sections correct ? And the mode ? Or is it too permissive ? For completeness the postfix setup is here : smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous # smtpd_delay_reject = yes smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, permit # smtpd_sender_restrictions = permit_mynetworks, reject_non_fqdn_sender, reject_unknown_sender_domain, permit # smtpd_recipient_restrictions = reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, permit # peter ---- Peter Skensved Dept. of Physics, Queen's University, Kingston, Ontario, Canada

[Dovecot] How to configure ssl cert chain in dovecot 10-ssl.conf file
by Bu Xiaobing 21 May '13

21 May '13

Hi there, Does anyone know how to do this: "Put all the certificates in the ssl_cert file. For example when using a certificate signed by TDC the correct order is: Dovecot's public certificate TDC SSL Server CA TDC Internet Root CA Globalsign Partners CA " I try to set these parameters in the conf.d/10-ssl.conf as below, but it seems doesn't work. --- ssl_cert = </etc/pki/dovecot/certs/mail.mymailserver.com.crt ssl_cert = </etc/ssl/certs/dovecot/sub.class1.server.ca.pem ssl_cert = </etc/ssl/certs/dovecot/ca.pem ---- I even cat mail.mymailserver.com.crt sub.class1.server.ca.pem certs/dovecot/ca.pem into one singe file, and define ssl_cert = < /path/to/the/singcertfile.pem, but it doesn't work too. In my apache httpd server httpd.conf file I can define: -- SSLCertificateChainFile /etc/pki/dovecot/certs/sub.class1.server.ca.pem SSLCACertificateFile /etc/pki/dovecot/certs/ca.pem -- And it well work fine. Thinks for any suggest. Bu Xiaobing

I've tested pipe with spam.sh that redirects stdin to /dev/null and returns 0 but errors were logged anyway. Note that spam.sh runs, getting the message from sieve and processing it to spamassassin without a problem, but "broken pipe" is being logged.

[Dovecot] Linking mdbox directories
by Alex Crow 20 May '13

20 May '13

Hi Timo/list, We have a scenario in which some email accounts on dovecot (stored in mdbox, separate paths for indexes, email, ALT storage and also using SIS for attachments, LDAP directory) need their names changed. I know we could just change the mail LDAP attribute (and leave mailMessageStore alone) so they keep the same directories on disk, but this would throw a spanner in the works for our backups. Would it be possible to create a hard link of the user's directories under the new name, and change the LDAP mailMessageStore attribute to point to these without stopping and starting dovecot? And after a while unlink the original locations? Or would this mess up dovecot's internal state?

Hi, im wondering if it's possible to store old messages in a compressed mdbox on alternate storage. The main storage is uncompressed mdbox. I tried something like: doveadm -Dv -o "plugin/zlib_save=gz" altmove -u testuser sentbefore 8d Could someone tell me if it's possible and give me a hint how this can be done? I tried this with dovecot-2.2 Claus

[Dovecot] Empty file in maildirs
by Roel Wagenaar 20 May '13

20 May '13

I am cleaning up some old users, and found that in every maildir folder there is an empty file called maildirfolder, created at the time the original dovecot was installed. Is this empty file necessary for dovecot, or is it left there in an upgrade proces and can it be removed?

[Dovecot] v2.2.2 released
by Timo Sirainen 19 May '13

19 May '13

http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz.sig It's been a while since v2.2.1. I think all of the bad bugs in v2.2 series should be fixed by now, so here's a new release. I think there are still some small URLAUTH bugs left though, so you might want to wait before enabling it in production (imap_urlauth_host is empty by default, which disables it). + zlib: Keep the last mail cached uncompressed in a temp file. This fixes performance when doing small partial fetches from a large mail. + acl: If plugin { acl_defaults_from_inbox = yes } is set, get the default ACLs for private and shared namespaces from the user's INBOX. (This probably will become default in v2.3.) + pop3: Added pop3_deleted_flag setting to switch POP3 deletions to only hide the messages from POP3, but still be visible via IMAP. - ACL plugin: Mailbox creation wasn't actually checking any ACLs and always succeeded (due to some v2.2 API changes). The created mailbox couldn't have been accessed though, so this couldn't have caused any data leak. - IMAP: Various URLAUTH fixes. - IMAP: Fixed a hang with invalid APPEND parameters. - IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag. - mailbox_list_index=yes still caused crashes. - maildir: Fixed a crash after dovecot-keywords file was re-read. - maildir: If files had reappeared unexpectedly to a Maildir, they were ignored until index files were deleted. - Maildir: Fixed handling over 26 keywords in a mailbox. - Maildir++: Fixed mail_shared_explicit_inbox=no - namespace { prefix="" list=no } was listing mailboxes. - imap/pop3-login proxying: Fixed a crash if TCP connection succeeded, but the remote login timed out. - Case-insensitive search/sort didn't work correctly for all unicode characters, as specified by i;unicode-casemap comparator. If full text search indexes were used, they need to be rebuilt for old mails to be handled correctly. (This bug has existed always in Dovecot.)

[Dovecot] Quota not working with dict proxy
by Chris Richards 16 May '13

16 May '13

Hello all, I'm sure this has been covered somewhere before, but my googlefu is not up to the challenge. Basically, I'm trying to configure quota plugin to use a dictionary service (specifically proxy with mysql) so that I can store the quota usage in a database and use that information in a lookup for postfix to reject mail if over quota. I'm doing this because postfix+avamis+dovecot setup with amavis re-injecting into postfix results in mail being effectively accepted before dovecot lmtp knows if mailbox is full. I'm currently using quota maildir: quota = maildir:User quota and this works; doveadm -Df tab quota get -u 'user@domain' Quota name Type Value Limit % User quota STORAGE 55388 204800 27 User quota MESSAGE 4883 - 0 When I use quota dict: quota = dict:User quota:%u:proxy::quota I get this: "doveadm -f tab quota get -u user@domain" Quota name Type Value Limit % User quota STORAGE 0 204800 0 User quota MESSAGE 0 - 0 So far so good. But manually setting database entry to values retrieved above with maildir quota results in this: Quota name Type Value Limit % User quota STORAGE 54 204800 0 User quota MESSAGE 4883 - 0 I'm guessing this is returning values in KB, so that makes sense, I guess. Attempting to recalc quota on one account using command: "doveadm -f tab quota recalc -u user@domain" returns with nothing, and when I repeat 'quota get' command, it says: doveadm(user@domain): Fatal: User doesn't exist Err............what?! Indeed, looking in the database shows the account in question was actually DELETED! Obviously, I've got something messed here, but I don't know what. I need some guidance here. Dovecot version is 2.1.12 Here is my config: # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 3.7.5-hardened-r1 x86_64 Gentoo Base System release 2.1 ext4 auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& auth_verbose_passwords = plain default_process_limit = 200 dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no login_greeting = Awaiting command... mail_location = maildir:/home/vmail/%d/%n/Maildir mail_plugins = " quota" mail_privileged_group = 100 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 ihave namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { expire = Trash 7 expire2 = Trash/* 7 expire3 = Spam 7 quota = dict:User quota:%u:proxy::quota quota_rule = *:storage=200M quota_warning = storage=99%% quota-warning 99 %n %d quota_warning2 = storage=95%% quota-warning 95 %n %d quota_warning3 = storage=80%% quota-warning 80 %n %d quota_warning4 = -storage=95%% quota-warning 'less than 95' %n %d sieve = ~/.dovecot.sieve sieve_default = /home/vmail/dovecot/sieve/default.sieve sieve_dir = ~/sieve sieve_global_dir = /home/vmail/dovecot/sieve } protocols = imap pop3 sieve lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = dovecot mode = 0666 user = dovecot } user = $default_internal_user } service dict { unix_listener dict { mode = 0600 user = vmail } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service quota-warning { executable = script /etc/dovecot/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = sieve quota postmaster_address = postmaster@domain } protocol lda { mail_plugins = " quota sieve quota" } protocol imap { mail_max_userip_connections = 20 mail_plugins = " quota quota imap_quota" } protocol pop3 { mail_plugins = " quota quota" } >From dovecot-dict-sql.conf.ext: connect = host=localhost dbname=maildb user=dbuser password=dbpass # CREATE TABLE quota ( # username varchar(100) not null, # bytes bigint not null default 0, # messages integer not null default 0, # primary key (username) # ); map { pattern = priv/quota/storage table = email username_field = address value_field = quota_bytes } map { pattern = priv/quota/messages table = email username_field = address value_field = quota_messages } # CREATE TABLE expires ( # username varchar(100) not null, # mailbox varchar(255) not null, # expire_stamp integer not null, # primary key (username, mailbox) # ); map { pattern = shared/expire/$user/$mailbox table = email value_field = expire_stamp fields { address = $user maildir = $mailbox } } Other than some guesswork, I've not got the FOGGIEST idea what the settings in the file actually mean; it doesn't seem to be documented anywhere. Also, the quota plugin settings, at least with respect to using a proxy service, don't seem to be real explanatory either, e.g. the reason I'm using %u for the user is because I stumbled across a post suggesting that leaving it blank would result in just getting the username instead of the username@domain. This is not at all obvious from the documentation, IMO. The docs would benefit greatly from some example use cases (no, I'm not volunteering; I'm TERRIBLE with documentation ;) ). Anyway, if someone could proffer some help or at least guidance here, I'd be very grateful.

[Dovecot] dovecot 2.2.0 corrupts mailboxes?
by manu＠netbsd.org 16 May '13

16 May '13

Hi On april 17th, I upgraded from dovecot 2.1.13 to 2.2.0. Since that time, I had two different users that reported received three incident of messages that disapeared from their mailboxes. The mailbox format is mbox on local FFS filesystem (no NFS), and I use filesystem quotas (but both users are far from filling their quotas). When the message disapeared, it was always a whole rand of dates. On the last incident reported, the user also saw some message being duplicated many times. There is something interesting in the logs: May 4 20:16:30 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (2000 < 8063) May 4 20:16:30 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 141869 May 4 20:19:48 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (9711 < 16248) May 4 20:19:48 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/Arxiv/dovecot.index.cache: Broken physical size for mail UID 4383 May 4 21:14:35 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (1878 < 8066) May 4 21:14:35 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/CNRS/dovecot.index.cache: Broken physical size for mail UID 290 May 4 21:15:17 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (17285 < 24440) May 4 21:15:17 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/Commandes/dovecot.index.cache: Broken physical size for mail UID 680 Does that ring a bell?

[Dovecot] quota with imapc
by pvsuja 16 May '13

16 May '13

Dear dovecot team, I have set up my mail system with a mail gateway connecting to mail server using imapc. Now I need my web mail client to show up the quota info. I enabled quota plugins in dovecot.conf. The problem is since all mails reside in the server, the web mail which is in mail gateway always shows the quota as 0. Is there any way the plugin will get quota info from the mail server? I am attaching my conf ## Dovecot configuration file in mail_uid = imapproxy mail_gid = imapproxy mail_home = /home/imapproxy/%u mail_location = imapc:~/imapc protocols = imap ## ## imapc settings ## imapc_host = mailserver.example.com imapc_port = 143 imapc_ssl = starttls imapc_ssl_ca_dir = /etc/postfix/certs ## ## auth settings ## auth_mechanisms = plain login passdb { driver = imap args = host=mailserver.example.com ssl=starttls ssl_ca_dir=/etc/postfix/certs default_fields = userdb_imapc_user=%u userdb_imapc_password=%w ssl=starttls } userdb { driver = prefetch } mail_plugins = $mail_plugins quota plugin { quota = maildir:User quota quota_rule = *:storage=200M } protocol imap { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = $mail_plugins imap_quota } ## ## SSL settings ## ssl = required disable_plaintext_auth = yes #verbose_ssl = yes ssl_cert = </etc/postfix/certs/public_cert.pem ssl_key = </etc/postfix/certs/private_key.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL Greetings. -- View this message in context: http://dovecot.2317879.n4.nabble.com/quota-with-imapc-tp42280.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Looking for a good way to manage passwords for CRAM-MD5
by Steinar Bang 15 May '13

15 May '13

I prefer not to use clear text passwords, even over an encrypted connection. With IMAP, the only such mechanism with widespread client support is CRAM-MD5 (please correct my if I'm wrong... I'd love to be corrected here...). On the dovecot 2 wiki, the only way I've found to implement CRAM-MD5 support, is to use a passwd-like file: http://wiki2.dovecot.org/HowTo/CRAM-MD5 I am running a small IMAP server used by my family. As long as I was the single user on the IMAPd, manually managing the passwd file as doable (if a bit cumbersome). With 2-5 users, I'm looking for a more elegant solution. Does anyone have a similar situation, and a solution they would like to share (config/HOWTO)? Here are the possibilities that comes to mind: 1. Create a web interface to change the password (does anyone know of a ready-made solution for this that they could recommend?) 2. Convince PAM to update the dovecot HMAC-MD5 password file as well as the regular system password file (my dovecot runs on a debian stable "wheezy" system. In theory this should be possible, but it is very hard to find documentation on what PAM modules exist, and how to write a new one, and if it is possible to chain modules in PAM, ie. use one module to update-this-passwd-file and then use a different module to update a different passwd file) 3. Use LDAP, which I think can also support CRAM-MD5 when using password lookups http://wiki2.dovecot.org/AuthDatabase/LDAP/PasswordLookups (learning how to set up LDAP is something I have avoided for years, because it looks awfully complex and time consuming) I haven't looked into using databases, SQL, or key-value store, because they seem like a more cumbersome way to do the same thing as passwd files. But I am aware that this assumption could be wrong. It could e.g. be easier to make the web interface idea work with a database manager, than messing around with setuid bits to safely update a passwd file owned and touchable only by the dovecot user. Thanks for any and all responses! - Steinar

[Dovecot] Crossrealm Kerberos problems
by Jonathan Hanks 15 May '13

15 May '13

I am running dovecot 2.1.7 on Debian Squeeze 64 bit, config information at the end of the email. I am working on a Kerberos/GSSAPI based setup that requires cross-realm authentication. I have regular GSSAPI working, I can log in using pam_krb5 with password based logins or with the GSSAPI support when using a kerberos ticket in the default realm. However when I attempt to authenticate using cross realm authentication the login fails (logs below). After perusing the source code I beleive that the problem is as such: All taking place in mech-gssapi.c 1. mech_gssapi_userok(...) calls mech_gssapi_krb5_userok 2. mech_gssapi_krb5_userok(...) calls krb5_kuserok(...) to verify that the given Kerberos prinicpal can log in as the requested user. 3. The authentication process is running as the Dovecot user so: 3a. krb5_kuserok(...) looks for ~dovecot/.k5login to authorize cross realm logins 3b. There is no ~dovecot/.k5login, thus no cross realm access is allowed 3c. It should be looking at the users .k5login ~poptest/.k5login 3d. This never happens and the login attempt fails I have the server set up to use system users specifically so that I can do cross-realm authentication. Do I have some basic configuration error? How do I change the authentication process to run as the user requesting to login? Should that be allowed? Another thought is to backport some of the patches proposed for 2.2 that remove krb5_kuserok from the loop. Thank you for any insight. This server is not in production use so I can experiment.

[Dovecot] Fatal: Can't finish POP3 UIDL command
by stevenfah 15 May '13

15 May '13

I have been setting up a new mail server and copied our client's old mail to it. The old server has Courier (under Plesk), we're using Dovecot on the new server. Most accounts seem to work fine (under IMAP or POP3), but for a few we're getting the following in the /var/log/mail.err. Error: Message ordering changed unexpectedly (msg #1: storage seq 140 -> 1) Fatal: Can't finish POP3 UIDL command And the affected accounts can't get at their email. Things work ok if people switch to IMAP but for some of our clients that is a difficulty, so we really need POP3 working. I used the Perl script given here to convert the mailboxes. The only fix we've found is the rename/delete the Dovecot-uidlist file for the affected mailboxes and we've done that, as it was only a few. The issue now is that more mailboxes are coming with the same error, even though they were fine originally. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Fatal-Can-t-finish-POP3-UIDL-command-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] quota-related crash for doveadm dsync operation
by Emmanuel Dreyfus 15 May '13

Hi I understand the crash below is caused by filesystem quota. I just report it because perhaps it could have a more graceful failure.

[Dovecot] Lucene and Zlib with 2.2.1
by Kyle Wheeler 15 May '13

15 May '13

Hello, I have an "archive" folder in my inbox, where I manually stick old mails into a compressed mbox format. Since upgrading to Dovecot 2.2.1, I've started seeing messages like the following in my log files: imap(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable imap(...): Error: indexer failed to index mailbox INBOX/Archive/2007/Sent.gz These errors *appear* to be mostly benign; I still get results from searching the mailbox. But for whatever reason, the indexer appears to not be working for those folders. As you can probably tell, I'm using the fts_lucene plugin, which used to work just fine (with Dovecot 2.1.x). Is this expected behavior? Are these errors truly ignorable? Why are these compressed mailboxes not selectable? ~Kyle -- Where justice is denied, where poverty is enforced, where ignorance prevails, and where any one class is made to feel that society is an organized conspiracy to oppress, rob and degrade them, neither persons nor property will be safe. -- Frederick Douglas
