29 May '12

http://dovecot.org/releases/2.1/dovecot-2.1.7.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.7.tar.gz.sig * Session ID is now included by default in auth and login process log lines. It can be added to mail processes also by adding %{session} to mail_log_prefix. + Added ssl_require_crl setting, which specifies if CRL check must be successful when verifying client certificates. + Added mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX". - v2.1.5: Using "~/" as mail_location or elsewhere failed to actually expand it to home directory. - dbox: Fixed potential assert-crash when reading dbox files. - trash plugin: Fixed behavior when quota is already over limit. - mail_log plugin: Logging "copy" event didn't work. - Proxying to backend server with SSL: Verifying server certificate name always failed, because it was compared to an IP address.

[Dovecot] Different SSL requirements for connections on different ports?
by William Gallafent 29 May '12

29 May '12

Hi All, I'm running dovecot 2.0.19. I currently have remote users access mail using IMAP over SSL, with their client certificates being both required and verified. I do this using "ssl = required" and "ssl_verify_client_cert = yes". I would now like to add a webmail front-end (squirrelmail) running on the same server. In order to achieve this I would like to have squirrelmail connecting locally using IMAP, but without the certificate requirement. I'm happy to use the standard IMAP port for this, since that port is firewalled so that only localhost has access. Do I need to run two separate dovecot instances in order to achieve this, or can I somehow configure different SSL requirements for the two ports? Is there a way to have the ssl directives I mention above active only for a certain port (or for certain hosts, i.e. non-local?) I've been looking around in the documentation, but I haven't yet worked out how to do this other than by having two separate dovecot instances running, with the different auth configurations. Is that the best approach, or can I get it working with only once instance? Thanks for any help! -- Bill Gallafent.

[Dovecot] Director and backend on the same server
by James Devine 29 May '12

29 May '12

I have setup director and a backend dovecot service on the same machine using different ports. The backend service is listening on the default 24, 110 and 143 for lmtp, pop3 and imap respectively. Director is listening on 10024, 10110 and 10143 for the same respective services. I can get this setup to work if I have one backend server on a different IP listening on 10024, it seems director tries to use the same port it is listening on when making backend connections. If I point it to the local backend server, it tries to connect to itself which fails. Is there a way to specify the backend ports that director tries to connect to? I see there is a way to specify the port in director_servers but I'm not sure how I would specify the different ports for the different backend services, if this is even possible.

[Dovecot] Dovecot 2.1 mbox + maildir
by Alan Brown 29 May '12

29 May '12

What syntax is needed to make this work? The 2.0 wiki recomendations don't work - I can see the inboxes or the folders but not both at once and there are lots of error messages about prefix clashes if I simply use the existing 2.0.20 conf file on 2.1.6 The layout I have is: Inboxes in mbox format - /var/spool/mail/%u Folders in maildir format - /var/spool/imap/%u/Maildir/ Control and index folders are under separate trees (/var/spool/control & /var/spool/indexes) There's also a mbox area mainly for moving oversized inboxes (/var/spool/imap/%u/mbox/ - prefixed as OLD) Presumably I'm not the only one who's had problems of this type? Thanks in advance for any help Alan

[Dovecot] Bug report - crash on group lookup
by Peter Meier 29 May '12

29 May '12

Hi I was doing some migration from a 1.2 installation to a 2.1. While testing my new installation dovecot crashed at two test-cases constantly with with a "Panic: Trying to allocate 0 bytes" message. Both times it was because I was using a wrong group (or none) in my config. The output I got by dovecot was not that helpful. I only figured it out, that it has something to do with the group by looking at the code, to figure out where the stacktrace I got could come from. Unfortunately, I don't remember one of the examples anymore that correctly (except that it was also a group configuration related issue). The other example, was that I was testing the quota warning scripts: Normal delivery worked fine, but as soon as dovecot should send a quota warning, after the mail got already delivered, I received said panic. For the MTA the mail delivery failed (-> bounce), although the LDA already delivered the mail, but failed in post processing (sending the quota warning). My fix was to add: unix_listener quota-warning { group = mail mode = 0660 } to the quota warning service. The LDA process has an own user per mailbox and the mail group. It looks to me as it would panic by looking up the user of the lda process, but that's pure guess. Attached is a debug output and the configuration that triggered the problem. I see two problems: 1. Don't panic while "looking" up a group 2. Give a meaningful error messages. If you have any further questions, please let me know. ~pete ==> /var/log/dovecot/debug.log <== May 25 12:19:50 lda: Debug: Loading modules from directory: /usr/lib/dovecot May 25 12:19:50 lda: Debug:

[Dovecot] Active Directory : searches in root tree
by nicolasfo 29 May '12

29 May '12

Hello everyone ! I'm trying to make a mail server with dovecot and postfix. Users will authenticate with Active Directory server. I've got an problem with Dovecot. To make the mail server, I'm using IredMail, and I used this tutorial : http://www.iredmail.org/wiki/index.php?title=Integration/Active.Directory.i… here Here's my dovecot-ldap.conf : hosts = dc.domain.lan:389 ldap_version = 3 auth_bind = yes dn = vmail(a)domain.lan dnpass = vmail_passwd base = ou=some_ou,dc=domain,dc=lan scope = subtree deref = never user_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) user_attrs = =home=/home/mail/%Ld/%Ln/Maildir/,=mail=maildir:/home/mail/%Ld/%Ln/Maildir/ pass_attrs = userPassword=password default_pass_scheme = CRYPT With this configuration file, it works. BUT : To allow Dovecot to find users in my AD database, I must specify an OU in "base". If I only set "dc=domain,dc=lan" the research doesn't work. It seems that Dovecot is not capable to make a research without an OU specified in base. Am I wrong ? The root research works fine with postfix, samba+winbind, and I've an enterprise sized hardware firewall, and it works fine too. I'll be surprised if you tell me that Dovecot can't make a research without OU... That's why I'm posting here.. I've already post about this problem on the Iredmail forum, http://www.iredmail.org/forum/post15184.html#p15184 here , but no solution were found. You're my last hope :) Thanks a lot for replies Nicolas -- View this message in context: http://old.nabble.com/Active-Directory-%3A-searches-in-root-tree-tp33881379… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] GETQUOTAROOT under roundcube
by Adam Szpakowski 29 May '12

29 May '12

Hi, I'm struggling with the proper quota displaying under roundcube webmail. I've tracked the problem to the different responses on GETQUOTAROOT command. Roundcube aquire quota usage using IMAP command: GETQUOTAROOT INBOX Example dump of the roundcube <-> dovecot communication: > GETQUOTAROOT inbox < QUOTAROOT "inbox" "User quota" < QUOTA "User quota" (STORAGE 1198415 10485760) < OK Getquotaroot completed. The same communication using python imaplib: > GETQUOTAROOT inbox < QUOTAROOT "inbox" "User quota" < QUOTA "User quota" (STORAGE 1431260 10485760) < OK Getquotaroot completed. Quota reported to python client is the same as the one reported to Thunderbird and seems to be the proper one. Python test was performed from the webmail same server, the same user. Can someone point me in the right direction? If there is no explanation on IMAP level i'll move the question to roundcube list. software used: - dovecot: 2.0.15, quota limit set in LDAP, usage tracked in SQL - roundcube: 0.7 - python: 2.6.7 Relevant parts of the dovecot config (taken selectively from different files): quota = dict:User quota::proxy::quota quota_rule2 = Trash:storage=+10%% quota_rule3 = spam:storage=+10%% user_attrs = mailQuota=quota_rule=*:bytes=%$ mail_plugins = quota imap_quota dict { quota = mysql:/etc/dovecot/dovecot-dict-used-quota.conf.ext } #dovecot-dict-used-quota.conf.ext map { pattern = priv/quota/storage table = used_quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = used_quota username_field = username value_field = messages } -- Adam Szpakowski
