[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

Hello, I have found this message in logs. But delivering is working. Error: User peter(a)mydomain.cz doesn't have home dir set, disabling duplicate database doveconf -n # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-lts i686 ext3 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:/home/vmail/%u 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 passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { home = /home/vmail/%u sieve = /home/vmail/%u/dovecot.sieve sieve_global_path = /home/vmail/dovecot-global.sieve } postmaster_address = postmaster(a)mydomain.cz protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } ssl_cert = </etc/ssl/dovecot/cert.pem ssl_key = </etc/ssl/dovecot/key.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = sieve } I have googled little bit. According to this article http://wiki2.dovecot.org/VirtualUsers/Home I think the problem is: mail_location = maildir:/home/vmail/%u and plugin { home = /home/vmail/%u } is the same directory. 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

[Dovecot] over quota issue
by PA 30 Dec '10

30 Dec '10

I have a situation where if a user is over quota and sending through postfix I get an error, now this error only happens if the user is over quota, otherwise it works with no problem. However if sending using /usr/local/libexec/dovecot/dovecot-lda it works every time even if overquota, any ideas? I just can't seem to figure this one out.
