[Dovecot] Problem redirecting email using pigeonhole 0.4.0 (with patch)
by Andriy Syrovenko 18 Jun '13

18 Jun '13

Hello, Starting from the version 0.4.0 Pigeonhole adds "X-Sieve" and "X-Sieve-Redirected-From" headers ending them with CR+LF, and then copies the original message (including original headers) ending the lines with LF-only. This causes troubles at least if using Exim (I have not checked with other MTAs)- original message gets dropped, and only the new pigeonhole-generated headers are sent out. The attached file fixed the problem for me. --- dovecot-2.2-pigeonhole-0.4.0.orig/src/lib-sieve/cmd-redirect.c 2013-04-07 01:57:26.000000000 +0300 +++ dovecot-2.2-pigeonhole-0.4.0/src/lib-sieve/cmd-redirect.c 2013-06-05 03:22:53.000000000 +0300 @@ -344,9 +344,9 @@ string_t *hdr = t_str_new(256); /* Prepend sieve headers (should not affect signatures) */ - rfc2822_header_write(hdr, "X-Sieve", SIEVE_IMPLEMENTATION); + rfc2822_header_append(hdr, "X-Sieve", SIEVE_IMPLEMENTATION, FALSE, NULL); if ( recipient != NULL ) - rfc2822_header_write(hdr, "X-Sieve-Redirected-From", recipient); + rfc2822_header_append(hdr, "X-Sieve-Redirected-From", recipient, FALSE, NULL); o_stream_send(output, str_data(hdr), str_len(hdr)); } T_END; Best regards, Andrey.

[Dovecot] Dovecot 2.2.2: doveadm user doesn't honor -x option
by Axel Luttgens 17 Jun '13

17 Jun '13

Hello, 1. Considering a user_query similar to this one: SELECT ... FROM ... WHERE CASE '%s' WHEN 'lmtp' THEN ... and issuing following command: doveadm user -x service=lmtp someuser(a)example.com the log shows: SELECT ... FROM ... WHERE CASE 'doveadm' WHEN 'lmtp' THEN ... and the query of course fails. The same config with Dovecot 2.1.16 yields expected results. 2. This is more a question. Issuing above command first writes this to the log: prefetch(someuser(a)example.com): passdb didn't return userdb entries, trying the next userdb Is there really an attempt to make use of the prefetch database? If yes, under which circumstances could it succeed? TIA, Axel

[Dovecot] Trash plugin
by Jason Pfingstmann 17 Jun '13

17 Jun '13

Hello all! I tried to post this earlier today, but it's stuck in a moderator queue for being too long, so here's a shorter version (mod, please delete the pending message from me, if you read this). I'm new to dovecot and just finished setting everything up. It's a postfix + dovecot + myql + spamassassin + postgrey virtual mail server. The issue I'm having (1 of 2) is that the Trash plugin isn't working, over-quota mail is being rejected despite a large piece that would bring it under quota with room to spare for the piece being delivered that is in the Trash folder. My configs (postconf -n, doveconf -n, trash.conf): http://pastebin.com/vFJ0rfZ6 It may be unrelated, but it seems postgrey isn't running either, but maybe those are partially tied together? Thanks for all your help! Jason Pfingstmann

[Dovecot] Trash plugin
by Jason Pfingstmann 17 Jun '13

17 Jun '13

Hello! This is my first dovecot install, which I put together by mixing and matching pieces of various online howtos (fortunately, Dovecot doesn't seem to be overly complex - a big plus). I've got it mostly working, but the trash plugin doesn't seem to be working right. Below are configs and some logs. Any thoughts? Also, any suggestions regarding my configuration? I can post other items for troubleshooting if they'd be helpful. -Jason Pfingstmann Here's my doveconf -n: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.6.2.el6.x86_64 x86_64 CentOS

[Dovecot] Transparent IMAP proxy
by Yonatan Broza 16 Jun '13

16 Jun '13

Hi, I'm considering patching Dovecot to work as a transparent (and virus scanning) IMAP proxy. What is the appropriate feature to extend? (I've considered the following: IMAPC and reverse proxying, with IMAPC looking more promising since it actually parses IMAP communication). Can anyone who is familiar with the IMAPC code recommend what are the most appropriate locations in the code to make the required changes? (I've considered hooking the storage virtual functions and making the settings local rather than global - but would appreciate more specific ideas). Thanks.

[Dovecot] Multiple user sharing a single mailbox
by Jonathon Price 16 Jun '13

16 Jun '13

I'm designing a system where some but not all groups of users want to share a single mailbox, i.e the user will not have there own inbox. I think this is possible by setting up a user database that returns the same mail location and possible the same home directory. This sharing would only occur in a single domain. Example User Database UserID | home | mail all(a)site1.example.com | /mail/home/site1.example.com/all | /mail/mailstorage/site1.example.com/all user1(a)site1.example.com | /mail/home/site1.example.com/user1| /mail/mailstorage/ site1.example.com/all user2(a)site1.example.com | /mail/home/site1.example.com/user2| /mail/mailstorage/ site1.example.com/all user1(a)site2.example.com | /mail/home/site2.example.com/user1| /mail/mailstorage/ site2.example.com/user1 user2(a)site2.example.com | /mail/home/site2.example.com/user2| /mail/mailstorage/ site2.example.com/user2 In this example all of site1.example.com users share a single mailbox, and site2.example.com users each have there own mailbox. Should the home directory also be shared, I read the comment that they should never be shared but wasn't sure if that still applied when the mailbox is the same path. For groups that are sharing a mailbox there would likely be a relatively low number of users concurrently logged in, say less than 10. For clustering we are currently limited to NFS mail storage. I was planning on using director setup so that the hashing/sharding is performed on the domain only, so all users for a domain will end up on a single node. At this stage clustering is mainly for high availability not performances. Lastly I'm concerned about possible issues with locking on the mailbox files and indexes. Will one of the mail formats reduces this risk, we can use any format as all mail will be written by Dovecot. Would giving each user there own index location help? and I assume this would mean that each user would see there own flags like read status? Does this setup sound ok, are there aspects that should change? thanks, Jon

[Dovecot] [Dovcot 2.2.2] Q: Prequisits for compiling and plugins
by Christoph Hintermüller 16 Jun '13

16 Jun '13

Hi Where can i find the list of prerequisites for compiling dovocot 2.2.2 form the sources, is there a dedicated link or what terms i should best use to search the archives of this mailing list, the documentation or the web? Where do I find information (links or search terms) whether plugins available for 1.x 2.1.x series, especially the metadata plugin, are still needed for 2.2.2 or may even be harmful for 2.2.2 as built in. Documentation on Dovecot webpage is rather sparse and not really conclusive concerning metadata plugin within 2.x series. On my Ubuntu 12.X systems i still find it for 2.1.x but I have difficulties to understand whether there exist a version for 2.2.X series, if this is equal to the one for 2.1.X or whether it is not needed any more for 2.2.X series. Further what libraries would be required. Greetings Christoph

[Dovecot] MULTIAPPEND + literal8 issue
by Michael M Slusarz 16 Jun '13

16 Jun '13

Background: importing a mbox file containing ~700 messages (20 MB). Our program splits MULTIAPPENDS into approx. 5MB chunks. We don't use literal+ in order to immediately catch errors. I can reproducibly produce the following error (2.2.2) when doing a MULTIAPPEND where every append is using literal8: [...340 messages appended in 7 previous APPEND commands...] C: 10 APPEND Test "16-Dec-2011 17:19:46 -0700" ~{3128} [...~30 APPENDed messages...] C: "18-Jan-2012 12:38:21 -0700" ~{2893} S: + OK [...2893 octets of data...] C: "18-Jan-2012 22:09:41 -0700" ~{6492} S: 10 BAD Error in IMAP command APPEND: Expected '{' S: 492} BAD Error in IMAP command : Unknown command. This error occurs about 340 messages in. If I switch to using regular literals, this error does not occur. I can verify that neither the 12:38:21 message nor the 22:09:41 message alone is broken (I can put just these two in a file and import and it is successful). I can provide the mbox file privately, if needed. michael

[Dovecot] rawlog without setting home in userdb
by Claus 16 Jun '13

16 Jun '13

Hi all, in my settup i decided to set mail_home in 10-mail.conf, and let dovecot do the hashing to a 2-level directory structure. mail_location = mdbox:~/mdbox:ALT=/altstorage/%h/mdbox mail_home = /vmail/%1Mu/%2.1Mu/%u In my userdb ist homedirectory not set and everythink works as expected, except when i use rawlog i get only logs in ~/dovecot.rawlog if home is set in userdb. In wiki http://wiki2.dovecot.org/Debugging/Rawlog it reads: If you don't have the home directory and you can't or don't want to modify userdb configuration, you can add: mail_home = /home/%u # or temporarily even e.g. mail_home = /tmp/temp-home Can you tell me, if my problem is the hashing-configuration or anything else?

[Dovecot] dovecot creating unknown users
by Yann Shukor 16 Jun '13

16 Jun '13

Hi We recently installed a dovecot postfix roundcube debian wheezy serverIt is now in production and we are feeling our way as we progressivelyadd new users to this local server. I noticed that dovecot is creating user directory structures for unknown users withinour domain in /var/vmail, even though we have setup a static users.conf db file. I tried omiting the "allow_all_users=yes" parameter but that doesn't seem to be linked to this issue Sorry if this has been asked a number of times already Is there an easy way to search the archives of this mailinglist ?

[Dovecot] Turn off IMAPS?

[Dovecot] Auto-responder to handle unencrypted (and/or unsigned) email messages whose origin is not localhost
by Ben Johnson 15 Jun '13

15 Jun '13

Hi, everyone, I'm surprised how little exists on the Internet regarding this particular subject. Given the recent headlines, that is about to change, I'm sure. I have a need to send an automated response to all senders who attempt to send unencrypted and/or unsigned email to a specific mailbox on my system. (Messages originating from localhost should be exempt.) I would like for the auto-reply to include a customized message with the appropriate public PGP key contained therein. Has anyone accomplished this? If not, some basic theory as to how one might go about achieving this would be greatly appreciated. Perhaps this is a job for Dovecot's "sieve_before" directive. Would this simply be a matter of checking the message body for the expected patterns, e.g., starts with "----- BEGIN PGP MESSAGE -----", etc., etc. and sending an automated reply with the public key if the expected strings are not present? Any additional thoughts would be very helpful! Thank you in advance, -Ben

[Dovecot] Pam authentication failure message but it works

I am running Centos 6.4 64bit. Dovecot 2.0.9 I am getting the following messages in /var/log/secure, which looks like the pam authentication is not working but the users are allowed to login and the system works great.

[Dovecot] Autocreation the home folder
by Joan 14 Jun '13

14 Jun '13

Sorry if this has been already asked, but I haven't been able to find a solution, I am trying to migrate a dovecot 1.2 config to 2.1, the 'dovecot -n > dovecot.conf' migrated all the setup without issues, and the mail is working as expected. The only issue I've had is with the change with the mail_location, mail_home, that in the 2.1 versions can't be on the same path. After reading in the wiki the various config options ( http://wiki2.dovecot.org/VirtualUsers/Home) I opted to use the 3rd: Home directory under mail, for example: Maildir: home=/var/vmail/domain/user/home/ mail=/var/vmail/domain/user/ mbox: There's really no good and safe way to do it. So I changed from: mail_location = maildir:/home/vmail/%d/%n mail_home = /var/vmail/%d/%n To: mail_location = maildir:/home/vmail/%d/%n mail_home = /var/vmail/%d/%n/home The problem is that those home directories are not created (the mailboxes already existed) automatically, and I am getting these errors: ========================================================== May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Home dir not found: /var/vmail/example.com/username/home May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota root: name=User quota backend=maildir args= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=* bytes=20480000000 messages=0 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=Trash ignored May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=15360000000 (75%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 75 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=17408000000 (85%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 85 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: maildir++: root=/home/vmail/example.com/username, index=, control=, inbox=/home/vmail/example.com/username, alt= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota root: name=User quota backend=maildir args= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=805306368 (75%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 75 ======================================================== Am I supposed to create the folders via an external script? Or is there any option to make this automatic. Regards, Joan

[Dovecot] dovecot segfaults after upgrade
by Thomas Blomenkamp 14 Jun '13

14 Jun '13

Using dovecot on debian oldstable (squeeze) with daily builded repository, after an upgrade this morning, dovecot always shows the following error: 2013 Jun 10 11:07:22 mailstore imap(tblomenk): Fatal: master: service(imap): child 3016 killed with signal 11 (core dumps disabled) Jun 10 11:07:22 mailstore kernel: [ 1589.400741] imap[3016]: segfault at 7fffd9048ff8 ip 00007f91417e2c3b sp 00007fffd9049000 error 6 in libdovecot.so.0.0.0[7f9141796000+bc000] Please notice: I can reproduce the error by trying to access my mailbox with alpine or mutt, while alpine only can access my inbox. If I try to access my other folders, the error happens. Mutt always closes the connection after trying to login. It is a little bit strange because with a newer client like roundcube I can access all my folders successfully. In all kernel error messages it seems that error 6 in libdovecot.so.0.0.0[7f9141796000+bc000] is always the same. Also notice that dovecot is still running, it is just that you cannot access other folders than your inbox with pine. mailstore:~# dovecot --version 2.2.2 (45399357008a) mailstore:~# dovecot -n # 2.2.2 (45399357008a): /etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (1324) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1227) # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.7 auth_debug = yes auth_gssapi_hostname = mailstore.math.uni-bielefeld.de auth_mechanisms = plain login auth_username_format = %n auth_verbose = yes lmtp_save_to_detail_mailbox = yes log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Hi, the IMAP Mail-System on mailstore.math.uni-bielefeld.de is ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_location = mdbox:~/mdbox mail_plugins = acl 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 spamtest spamtestplus imapflags notify namespace { list = children location = mdbox:%%h/mdbox prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size mail_log_group_events = no quota = maildir:User quota quota_rule = *:storage=0 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags +notify +spamtest +spamtestplus sieve_spamtest_max_value = 100 sieve_spamtest_status_header = X-PMX-Spam: \.*Probability=([[:digit:]]+)%+\.* sieve_spamtest_status_type = score } protocols = imap lmtp sieve service auth { unix_listener auth-master { mode = 0600 user = vmail } unix_listener auth-userdb { user = vmail } user = root } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 0 } process_limit = 1024 process_min_avail = 10 service_count = 1 } service imap { process_limit = 1024 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 vsz_limit = 64 M } ssl_cert = </etc/dovecot/mailstore_cert_chain.pem ssl_key = </etc/ssl/private/mcl_key.pem userdb { args = uid=vmail gid=vmail home=/var/vmail_san2/dovecot/%1Lu/%Lu driver = static } protocol imap { mail_plugins = acl imap_acl } protocol lmtp { mail_plugins = acl sieve } protocol sieve { mail_max_userip_connections = 50 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 } Regards, Thomas
