UID 26624 is a valid user ('info' of domain14552) but under a compleltly different domain name (hamish is under domain25367). However that user has also not logged in around the time the ownership was changed. There is no relevance to the two users, except that they exist on the system and for some reason this issue happened to the hamish user. The NFS server does not know about the UIDs, it just provides the numeric IDs which is translated on the dovecot/exim servers by NSS and Dovecotr using the replicated MySQL database. Additionally both users have existed for some time and the databases are in sync. Customers also do not have any access to the file system so there will be no symlinks in place. Its also not a single server that we are seeing the issue on, it maybe one Dovecot server accessing one NFS server. Then the next time its a different Dovecot server accessing a different NFS server. >> >the logs for that time which is abnormal (a whole bunch of other logins from >> >other customers but nothing from those two users and no errors) > What about cron jobs, message delivery, backups, ... anything that > possibly can alter that file. I don't think, it's a Dovecot issue, unless > the uid 26624 is valid and hamish is shared with that user. Nothing besides Courier being replaced by Dovecot has changed in the server setup (although I could be wrong there, but we are going through one component at a time and until this issue is resolved we are not moving onto the next), and the only file which is being modified is a file which only Dovecot maintains. There are hourly backups which do an rsync to another server in case of hardware failure, there are scripts which move mailboxes between NFS servers but they show up in logs. Exim has no need to touch a dovecot controlled file, and when it writes mail into the maildir its writing as the correct user. It also seem odd that one login is fine then randomly the next login the file ownership has changed, nothing happens in between the two logins which are in some cases only 5 to 10 minutes apart. All I am really looking for is ideas on where to look, as it seems odd that nobody else is reporting this, and since its a reasonably new setup its possibly something we have done in the config (which I posted in my first email). Is there a reliable way to run a script directly when a dovecot session starts and finishes so we could output the ownership before and after which may also help eliminate the session itself. Cheers, Bruce

[Dovecot] empty emails with 2.2.13/pigeonhole
by Cor Bosman 04 Jun '14

04 Jun '14

I recently upgraded from 2.2.10 to 2.2.13, and also upgraded pigeonhole. Ever since im seeing some empty emails appear in my inbox. Return-Path: <cricket(a)stats2.xs4all.net> Delivered-To: <cor> Received: from imapdirector1.xs4all.net ([194.109.26.173]) by userimap9.xs4all.nl (Dovecot) with LMTP id CHu0MUDDjlOBdwAAwvsqNQ for <cor>; Wed, 04 Jun 2014 08:57:04 +0200 Thats all this mail contains. This only happens using LMTP/Sieve, and with many different senders/recipients. Debug log shows nothing out of the ordinary, except that the mail seems to be corrupted by the time it hits sieve. It's very hard to diagnose. Our path is kind of lengthy, and in theory it could happen everywhere. Mail first arrives on incoming MX server which is sendmail. From there it's sent to a dovecot director using lmtp, which sends it to a server that does final delivery with sieve. Im not sure where the email gets corrupted. Any extra debugging I could turn on? Two extra things to note. So far it seems to only happen to emails that would have hit a matching sieve filter rule. I have asked a dozen people to verify this, and all emails would have matched a filter if all was well. Instead, it gets dropped into the inbox because pigeonhole seems to be working with the corrupt file and cant match any rules anymore. And second, 99% of our email is handled differently, from the sendmail server directly into a local mailer, and that never causes issues. We're in the process of switching to lmtp. Any insights? cor

[Dovecot] /etc/passwd userdb and long usernames
by Nicolás Reynolds 04 Jun '14

04 Jun '14

hi! i've configured dovecot to lookup usernames in /etc/passwd and it's working ok but it's having some problems retrieving info when the username is longer than 32 chars (i know it isn't recommended but everything seemed to work ok except for the hardcoded limit in useradd...) i found this on logs showing extra characters on the home field: http://pastie.org/pastes/9257902/text?key=vsxstofu3rf5wum4aic5va is there a limit on username length? i "solved" it by setting auth_username_format = %0.30u -- http://partidopirata.com.ar

[Dovecot] Dovecot + NFS + FreeBSD breakage ?
by Xavier Beaudouin 04 Jun '14

Hi, I am trying to update my old mails servers from dovecot 2.1.15 to 2.2.12 (freebsd ports) and upgrade to FreeBSD 10.0-P3. My mail storage are on NFS with index also. On 2.1.15 everything is ok, and in 10-mail.conf I have the good things to be added as wiki tell me (eg http://wiki2.dovecot.org/NFS) BUT, when I try a single connection like : $ telnet ::1 110 Trying ::1...

[Dovecot] Change in LAYOUT=fs between 1.2.9 and 2.0.19?
by Martijn 04 Jun '14

04 Jun '14

While testing an upgrade from Dovecot 1.2.9 (on Ubuntu 10.04 LTS) to 2.0.19 (12.04 LTS) I encountered the following change in behaviour: In both setups, mail_location is defined as follows: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs No other mail_location-related settings are set in the config. On 1.2.9 this leads to new mail being delivered to this example directory: /home/username/domains/example-domain.ext/webmaster/.Maildir/INBOX/new/ On 2.0.19 the exact same mail_location is set, but new mail is now delivered to: /home/username/domains/example-domain.ext/webmaster/.Maildir/new/ Notice the missing /INBOX/ in the path on 2.0.19. I found no mention of this change on http://wiki2.dovecot.org/Upgrading/2.0 which first lead me to suspect this was a bug in 2.0.19. However, while browsing the 2.0-wiki I found a page which sheds some light on the behaviour that is to be expected from Dovecot 2.0.x. Quote from http://wiki2.dovecot.org/MailLocation/Maildir#Directory_layout > "Mailbox directory name": "Without DIRNAME, INBOX will be stored at ~/Maildir/{new,cur,tmp}/, but when DIRNAME is specified, we get an extra path component INBOX/ immediately prior to the DIRNAME value, so in the example above INBOX would be stored at ~/Maildir/INBOX/mAildir/{new,cur,tmp}/." I then changed mail_location to have an empty DIRNAME, like: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs:DIRNAME= It appears this fixes the problem for new mail arriving (haven't tested other folders yet). Questions: 1. Is this a deliberate change in behaviour between the two versions? If so, may I suggest adding this change to the Upgrading to 2.0 wiki page, because I was unable to find the relevant info quickly. If not, is this a misconfiguration on my side, or a (known) bug in one of the two versions? 2. Is the DIRNAME=(empty) a good solution, or is it unusual/hacky to leave DIRNAME empty? Any particular problems I may expect using this configuration? Thanks in advance for your help. -- Kind regards, Martijn

[Dovecot] Info about sharing mail folder
by Gianluca Calloni 03 Jun '14

03 Jun '14

Hi to all. First of all.. I'm new on the mailing list.. So.. Sorry in advance for any mistake or error on posting here.. The question (or doubt..) is about sharing mail folder. I use a test mail server. Is not the production server (always dovecot + postfix + spamassassin + clamav) Well.. In test mail server i can use the share folder, follow the conf istruction on wiki dovecot. And work fine. But i need to know if is possible for user_a(a)mydomain.com to share only 1 or 2 subfolder (E.g. .INBOX.FOLDER_A and .INBOX.FOLDER_B shared, .INBOX_FOLDER_C not shared) When i do some test sharing folder, the user with wich user_a(a)mydomain.com share the mailbox can view all the subfolder of user_a(a)mydomain.com Following my dovecot versione e config. Thank's in advance My dovecot version is 2.0.19 My dovecot conf is : # 2.0.19: /etc/dovecot/dovecot.conf doveconf: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied calloni@dovecot:~$ sudo -i [sudo] password for calloni: root@dovecot:~# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-49-generic i686 Ubuntu 12.04.4 LTS ext4 dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = acl mail_uid = vmail namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = yes location = maildir:%%h:INDEX=~/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl } postmaster_address = postmaster(a)jodovit.local protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Thi
