[Dovecot] Sieve rule issue with certain character sets
by Thomas Leuxner 01 Jan '11

01 Jan '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a global sieve rule in place to filter mailing-lists. This has worked well so far. Recently however one subscriber on a list seems to create strange character set encodings in the 'From' and 'To' headers. This leads to unprocessed/unfiltered mails (no errors thrown). Is this a configuration or Pigeonhole issue (latest HG used)? Headers from failing mail: From: "=?UTF-8?B?VG9yaW50aGllbA==?=" <user(a)domain.tld> To: "=?UTF-8?B?ImJpbmQtdXNlcnNAbGlzdHMuaXNjLm9yZyI=?=" <bind-users(a)lists.isc.org> Relevant sieve rule: if allof (address :is ["To","CC"] ["bind-users(a)lists.isc.org","bind-users(a)isc.org","comp-protocols-dns-bind(a)isc.org"], header :contains "List-Id" "bind-users.lists.isc.org") { fileinto "Public/Mailing-Lists/Bind-Users"; } Regards Thomas -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.16 (Darwin) iEYEARECAAYFAk0dvZ4ACgkQ+meF/S97aXgYTACfZC70bsYn3d4/VRY2GfK5lF0k xOIAnRsBliv9EErA919vc5KoTAHhq3rC =IE3C -----END PGP SIGNATURE-----

[Dovecot] Dovecot 1.2.12 + Postfix + virtual domains: delivering to system users
by Ran Talbott 01 Jan '11

01 Jan '11

As mentioned in my previous posting, I've set up a mailserver for a domain of Winboxen, authenticated through Active Directory. After some struggles, I finally got that working. But I also need to receive emails for a few system users on the mailserver (like postmaster, and a couple of accounts set up for maintaining the system). I thought, based on the way I read the documentation, that I could just add a "userdb passwd", ahead of the "userdb ldap", and deliver would find their home directory maildirs. The virtual users would fail the passwd search, fall through to the LDAP check, and deliver would drop their mail into their maildirs in the /var/mailstore tree. I knew the system users wouldn't be able to login to the IMAP server, but this isn't a concern. Instead, the system users' mail got bounced, after an auth check via the "master" socket (from Postfix, I guess: it's a transient process) whose details don't get logged. And the virtual users' lookups (done by deliver) returned made-up UIDs and GIDs, and maildir locations (/home/<realm>/<username>) completely different from what the LDAP lookup normally returns (/var/mailstore/<username>). So what am I missing here? I managed to work around this by adding the system users to the Postfix virtual.db, but it would be nice to not need to do that. It would also be nice to neable the system users to check email by logging in to the IMAP serve, but I'm reluctant to even try that after the way delivery went completely wonky. Thanks, Ran

[Dovecot] Can doveadm rebuild thread indexes?
by David Warden 30 Dec '10

30 Dec '10

I'm already using "doveadm search" to update my squat fts indexes (dovecot.index.search and dovecot.index.search.uids) but I'd like to also update dovecot's thread index file (dovecot.index.thread) using doveadm. I checked the new wiki and the archives but didn't see any option for this. (I'm running 2.0.8) The alternative (AFAIK) is to write a script that signs in to IMAP and does "thread references UTF-8 ALL" in each folder. As an aside, could the dovecot LDA do any of this work? I'd surely be willing to spend the resources at delivery time to keep those indexes updated if it meant I didn't have to run a cron job to keep them updated. -David Warden

[Dovecot] LDAP binds
by Trever L. Adams 30 Dec '10

30 Dec '10

I am using 2.0.8. Anonymous binds are no longer supported in the environment I am using. I need to change my userdb ldap setup to bind. I believe the ldap server does Kerberos (or can) authentication. My users are authenticating using Kerberos or Kerberos/PAM. This needs to stay in place. Can anyone suggest how I might go about changing my setup to work? My current ldap setup is as follows (the directories, user id, etc are set statically in the configuration elsewhere): tls = yes hosts = MAILSERVER base = dc=middleearth,dc=sapphiresunday,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) Thank you, Trever Adams -- "Seize the day, put no trust in the morrow!" -- Quintus Horatius Flaccus (Horace)

[Dovecot] doveadm search
by dovecot 30 Dec '10

30 Dec '10

I would like to have soem information added to this page: http://wiki2.dovecot.org/Tools/Doveadm/Fetch Under 'Arguments'/fields is mentioned that 'hdr' could be used. But i wanted doveadm to just return the header of my message I found out, by simply trying, that next statement works: $ doveadm -f table fetch -u <username> "date.sent mailbox hdr.Subject" subject seomthing date.sent mailbox hdr.subject 2010-12-30 11:56:38 (+0100) INBOX RE: Question about seomthing 2010-12-30 13:24:29 (+0100) INBOX RE: Question about seomthing 2010-12-30 11:12:33 (+0100) Sent Question about seomthing 2010-12-30 12:11:19 (+0100) Sent Re: Question about seomthing I think it would be nice to add information to the field 'hdr' to let people know that 'hdr.Subject' is also allowed. -- Luuk

[Dovecot] dovecot-keywords problem with MDN
by Mauro D. 30 Dec '10

30 Dec '10

Hi all, I have Dovecot 1.2.13 installed. My clients ask why Disposition-Notification is requested every time the mail is moved on a new IMAP folder... I take a look into dovecot-keywords file and I see that: 1) I have only one row 0 NonJunk 2) dovecot-keywords file is not present inside every directory. How I can restore normal status? Where is probably the problem? Thanks Mauro D.

[Dovecot] Error: User doesn't have home dir set, disabling duplicate database

Is it right? Is the solution to set mail_location = maildir:/home/vmail/mail/%u ? -- Best regards Filip

[Dovecot] IMAP messages not being marked read
by void372＠transientvoid.com 30 Dec '10

30 Dec '10

I recently moved from Fedora 13 to Fedora 14 and consequently to dovecot 2.0.8. Since then, I have observed that messages are not being marked as read in all cases. The general behavior is: 1. Use my mail client to read all unseen messages. All mail folders show no messages unread. 2. Tell mail client to check for new mail. 3. Mail client now says that some folders have new mail (1 or more messages) 4. Clicking on a folder with new mail (say with 6 unread) shows that there are no unread messages. I have observed this behavior using both kmail and squirrelmail so do not believe it is a mail client problem. I have maildir folders to which mail is delivered using procmail recipes directly to the appropriate dovecot folder. In these folders, I notice that the "cur" directory has a matching number of messages that do not have an "S" flag on the end of the file name. For example: # ls .fedora-list/ cur/ dovecot.index.log new/ dovecot.index.cache dovecot-uidlist tmp/ # ls .fedora-list/cur 1293379204.26554_1.nehalem.home.rainbowdreams.com:2,S 1293379206.26571_1.nehalem.home.rainbowdreams.com:2, 1293379207.26581_1.nehalem.home.rainbowdreams.com:2, 1293380106.26744_1.nehalem.home.rainbowdreams.com:2, 1293380106.26748_1.nehalem.home.rainbowdreams.com:2,S 1293381904.26876_1.nehalem.home.rainbowdreams.com:2,S 1293383704.26978_1.nehalem.home.rainbowdreams.com:2,S 1293384604.27005_1.nehalem.home.rainbowdreams.com:2,S 1293385504.27067_1.nehalem.home.rainbowdreams.com:2,S 1293386404.27105_1.nehalem.home.rainbowdreams.com:2,S 1293387305.27158_1.nehalem.home.rainbowdreams.com:2, 1293387305.27166_1.nehalem.home.rainbowdreams.com:2, 1293388204.27193_1.nehalem.home.rainbowdreams.com:2, 1293389105.27234_1.nehalem.home.rainbowdreams.com:2,S 1293390005.27292_1.nehalem.home.rainbowdreams.com:2,S 1293390006.27298_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27400_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27406_1.nehalem.home.rainbowdreams.com:2,S 1293393611.27515_1.nehalem.home.rainbowdreams.com:2,S 1293396304.27673_1.nehalem.home.rainbowdreams.com:2,S 1293396305.27675_1.nehalem.home.rainbowdreams.com:2,S 1293398104.27743_1.nehalem.home.rainbowdreams.com:2,S 1293399003.27966_1.nehalem.home.rainbowdreams.com:2,S I have so far been unable to observe a pattern as to which messages get affected. I made the assumption that perhaps the issue is a conversion issue in my existing maildir folders, but this does not appear to be the case. When I moved the existing directory out of the way and started with a fresh empty directory the issue has come back after a day or two. Unfortunately, my install of Fedora 14 overlaid the partition with Fedora 13, so I cannot confirm the version of dovecot I was using with no issues. (so very glad I use separate disk and partition for the OS!) I can say that all configuration was in one dovecot.conf file, not the multiple conf.d files I see on Fedora 14. Any assistance on what to troubleshoot next is greatly appreciated! The info about my dovecot is shown below. The maildir's are on local LVM/RAID and not remote. Thanks!! # dovecot -n # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.10-72.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext3 disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/vg02/mail/%u mbox_write_locks = fcntl passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size flags } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } # dovecot --version 2.0.8

[Dovecot] Dovecot consulting companies
by Timo Sirainen 30 Dec '10

30 Dec '10

Once in a while someone asks about companies who could help installing / running / etc. their mail server. I don't really know many, so I thought I'd add a wiki page about it. Feel free to add your company on the list if you offer some Dovecot related services. Write also a few words what type of services you offer. http://wiki2.dovecot.org/Consulting I'll add a link there once at least one company is listed. :) Oh and if it's not clear above, I don't mean that the list should contain companies that only offer email accounts (Dovecot or not).

[Dovecot] Reverting from 2.0. to 1.2
by Thomas Hummel 30 Dec '10

30 Dec '10

Hello Timo, I switched this morning from dovecot-1.2.12 to 2.0.8 with a basic setup (high performance login mode, Maildir, everyhing on NFS, one shared but unused namespace). No problem so far except that some Thunderbird users who wouldn't succeed in moving messages from some one folder to another. They'd get a message about some illegal character in the mailboxname (already existing mailbox of course). This is user input so I don't have any details nor sufficient element to consider it a real problem. A Thunderbird restart seems to solve the problem. My questions were : . is there a different handling in the hierarchy separator (internal or advertized for the namespace) ? (I use "/" for both namespaces and "." since in Maildir). . is there a different handling in the non-ASCII mailbox names ? Could it be related ? . if something goes really wrong, is it safe to revert to 1.2.12 ? Maybe some files has non-compatible format (dovecot-uidlist, indexes, ...) ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau
