[Dovecot] doveadm delete-user ?
by Jan-Frode Myklebust 04 Nov '11

04 Nov '11

IMHO it would be great if we could both provision and un-provision users without having the provisioning system mess with files in the filesystem. Provisioning new users works fine since dovecot will create all files/directories on first login, but I haven´t found the tools to un-provison them. I see "doveadm mailbox delete" can delete individual mailboxes, but what about indexes, sieve-scripts and home-directories? Are there any tools to clean out these ? -jf

[Dovecot] Restricting IMAP access
by Thierry de Montaudry 04 Nov '11

04 Nov '11

Hi list, I have a setup with postfix+dovecot+mysql unser CentOS 5, running 50 odd domains with virtual users. Access is allowed for public POP3, and a webmail on apache+PHP solution through local IMAP. I'm not gonna give you the long story about the why, but I'm looking for a way to give public IMAP access only to one domain, knowing that users log in with full email (user(a)domain.tld) Anybody has a trick for that? Running dovecot 2.0.13. I know there should be a way to do it through the database, but quite heavy change on our side for a million odd users. Regards, Thierry

[Dovecot] Dot Lock timestmap, users disconnections from roundcube
by Maria Arrea 04 Nov '11

04 Nov '11

Hello. We are running dovecot 2.0.13 with mdbox+zlib on RHEL 5.7 x64, ext4. We use NTP. Indexes are in a iSCSI raid 10, mailboxes in raid5. No NFS. We have detected that sometimes all users get disconnected from roundcube at the same time. In dovecot logs we hundreds of lines like this: Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Warning: Created dotlock file's timestamp is different than current time (1320308587 vs 1320308542): /buzones/mydomain/03/67/mcrivero/subscriptions Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Connection closed bytes=0/295 Nov 3 09:23:07 buzon dovecot: imap(delolmo@mydomain): Warning: Created dotlock file's timestamp is different than current time (1320308587 vs 1320308542): /buzones/mydomain/15/77/delolmo/subscriptions Nov 3 09:23:07 buzon dovecot: imap(delolmo@mydomain): Connection closed bytes=0/295 I have been googling but I only see problems with remote NFS, our setup does not use NFS.

[Dovecot] IMP, Dovecot and multiple namespaces
by Rick Romero 04 Nov '11

04 Nov '11

Hey guys, I'm wondering what the best way is to be backwards compatible with Courier mailbox formats and not duplicate mailbox trees with Dovecot. Is anyone doing this right now? My Dovecot 2.0.13 is configured as follows for Namespaces: namespace { inbox = yes location = prefix = separator = . } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } So I should have an INBOX, plus additional root folders - rather than the Courier default of all folders being subfolders of the INBOX. So when I run LIST in IMAP I get - 08 LIST "" % * LIST (\HasChildren) "." "INBOX" * LIST (\HasChildren) "." "Spam" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Junk" * LIST (\HasNoChildren) "." "Drafts" Which looks fine. The problem is, IMP (old and new) show two sets of mailboxes (one for each namespace) like so: INBOX Spam Spam.Over10 Sent INBOX.Spam INBOX.Spam.Over10 INBOX.Sent (etc) I assume IMP is walking the INBOX because it says it has Children, and displaying those Children - The Horde team is telling me that's the root of the problem. It makes sense, but I'm not sure what the real solution is. Is it possible to disable Children for a mailbox when an alternate hidden namespace matches the mailbox name? Does that make sense? Or, is there another option I change change in the dovecot config to accomplish the same? Rick

[Dovecot] Different default realm per listener
by Kai Arif 04 Nov '11

04 Nov '11

Hi all! I want create a large IMAP server setup where dovecot is listening on multiple interfaces and needs a different default realm on each interface. I'm using dovecot 2.0.5 on FreeBSD9 and authenticate against a LDAP database. I found an old mail thread from 2007 that said I'm basically screwed. Has that change since than? Is there any way to use different default realms per listener?

[Dovecot] LDAP w/SASL "Active Directory" authentication failing.
by David Varela 04 Nov '11

04 Nov '11

Hello, I am running a Dovecot server (version 1.2.17) on FreeBSD 8.2, using LDAP to authenticate Active Directory users. I can successfully bind and authenticate using PLAIN and LDAP without SASL, but obviously passwords for the bind user and the user being authenticated are being passed in plain text. I've attempted to configure my server to us SASL however when I attempt to authenticate a user I see authentication failures. I reviewed the security log on my domain controller and see that the bind user is binding properly, so the issue appears to be orginating from the user authentication, however I cannot determine what the issue is. Here is all the information regarding my configuration, along with the logs from the server: Dovecot -n # 1.2.17: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-RELEASE i386 ufs log_path:

by Osvaldo Alvarez Pozo 04 Nov '11

04 Nov '11

Hello all, I am testing postlogin script with dovecot 2. I works but i would like that the imap and pop session get executed even if the post-login script fail. my postlogin script is very simple: #/etc/dovecot/conf.d/10-master.conf service imap { executable = imap imap-postlogin } # service imap-postlogin { executable = script-login /usr/local/bin/postlogin.sh unix_listener imap-postlogin { } } service pop3 { executable = pop3 imap-postlogin } #/usr/local/bin/postlogin.sh echo "UPDATE mailbox SET last_login = now() WHERE username = '$USER'" | mysql -upostlogin -pXXXXXXXX postfixadmin exec "$@" Thanks in advance Osvaldo

[Dovecot] What owner/permissions for virtual homes?
by sean darcy 04 Nov '11

04 Nov '11

VirtualUsers.Home.txt: The directory layouts for home and mail directories could look like one of these (in the preferred order): 1. Mail directory under home, for example: home='/var/vmail/domain/user/' mail='/var/vmail/domain/user/mail/' Who should be the owner of these directories, with that permissions? Does it make a difference if it's /home/vmail rather than /var/vmail? Thanks, Jay

[Dovecot] doveadm 'proxy list' or 'who' not working ?
by de Lafond Guillaume 04 Nov '11

04 Nov '11

Hi, I switched from dovecot 1.2.* to 2.0.* for a mail proxy. I try to play with the new cool utility doveadm, but I don't manage to get results from it. # /usr/local/dovecot-2.0.15/bin/doveadm proxy list username proto src ip dest ip port # As 'proxy list' does not return anything, I tried with 'who' # /usr/local/dovecot-2.0.15/bin/doveadm who -a /var/run/dovecot-socket-auth/anvil username # proto (pids) (ips) # I think it should display something as I have many user connected : #ps axww | grep imap ... 21194 ? S 0:11 dovecot/imap-login [13 connections (8 TLS)] 21195 ? S 3:38 dovecot/imap-login [47 connections (38 TLS)] 29463 ? S 1:00 dovecot/imap-login [210 connections (183 TLS)] ...

[Dovecot] POP server migration and duplicate messages.
by Ernie Dunbar 04 Nov '11

04 Nov '11

I'm having trouble with Dovecot where my mail client (if it matters, I'm using Evolution) collects some duplicate messages when switching between POP servers that have the same messages on them. I'm doing this as a test for server migration for all of our clients. Here's my procedure: 1. set up Dovecot and Exim on the new server so that everything works like on the old server. The old server also uses Dovecot and Exim, so very few things changed. 2. On the new server, use NFS to access the users' Maildirs on a remote NFS server. 3. Sync the Maildirs on the NFS store from the old server with SCP (and I do a quick SCP sync on my own Maildir during testing to ensure that this process is quick). 4. Check mail in Evolution on the old server. 5. Change Evolution's server settings to use the new server. 6. Check mail again. Evolution is set to keep messages on the server for one week, and about 20 of the 184 messages on the server keep getting re-downloaded. From a random sampling, the UIDL of the messages checks out between both servers, so I really don't understand what's going on here. If this is just a bug in Evolution, then that means I can just go ahead with the full migration and hope that people aren't going to be stuck with re-downloading their entire mailbox which in some cases, means hundreds or thousands of messages.

[Dovecot] GSSAPI and deny=yes passdb
by Sergey Urushkin 04 Nov '11

04 Nov '11

Hi. Is it possible to use GSSAPI authentication and deny passdb together? Seems it doesn't work as I expect: GSSAPI doesn't check deny passdb, so I'm not able to restrict access to GSSAPI-users. I can see these in logs when user tries to connect with PLAIN authentication (via pam_krb5): Oct 4 11:14:31 vm03 auth: Debug: passwd-file(testuser,172.17.0.123): lookup: user=testuser file=/etc/dovecot/auth.d/.passwd-deny Oct 4 11:14:31 vm03 dovecot: auth: passdb(tesetuser,172.17.0.123): User found from deny passdb But that's what I see if user logs in with GSSAPI: ...

[Dovecot] dovecot evaluation on a 30 gb mailbox
by Rajesh M 04 Nov '11

04 Nov '11

hi all i use qmail toaster. i recently changed over to dovecot. posting below my evaluation on the same my machine dual core dual xeon 5140 processor, with 4 gb ram, centos linux with qmailtoaster i had setup a qmail tap account which backups up data for a client of mine mailbox size over 30 gb setup dovecot with squirrelmail and logged in it had over one hundred and thirty nine thousand emails 139019 emails in the 30 gb mailbox Reports 1) first login : took 7 minutes to parse 139019 mails but never timed out. this was simply impossible with courier 2) the next login it took 5 seconds by which time the mail numbers increased to 139045 3) next i changed squirrelmail display preference to list 500 mails per page and then clicked on inbox ... expecting dovecot to take atleast around 1-2 mins to show the mails ... the mails were displayed in just 8 seconds .. awesome performance qmailtoaster is simply waiting for a dovecot integration i am evaluating the stability of dovecot now in the next 2-3 weeks i post stability report rajesh

[Dovecot] Expire plugin not executing for sieve plugin?
by Dan Swartzendruber 04 Nov '11

04 Nov '11

Running dovecot 1.2.12 on ubuntu 10.10. Here is the problem: I have mysql backend for expire. I am using the dovecot-postfix package which creates /etc/dovecot/conf.d/01-mail-stack-delivery.conf which looks like this: # Some general options protocols = imap imaps managesieve disable_plaintext_auth = no ssl = yes ssl_cert_file = /etc/ssl/certs/ssl-mail.pem ssl_key_file = /etc/ssl/private/ssl-mail.key ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM mail_location = maildir:~/Maildir auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ # IMAP configuration protocol imap { mail_max_userip_connections = 10 imap_client_workarounds = outlook-idle delay-newmail mail_plugins = expire } # LDA configuration protocol lda { postmaster_address = postmaster mail_plugins = sieve expire quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } # Plugins configuration plugin { sieve=~/.dovecot.sieve sieve_dir=~/sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve } The sieve is: require "fileinto"; require "imap4flags"; if header :contains "X-Spam-Flag" "YES" { setflag "\\Seen"; fileinto "SPAM"; stop; } Originally, this did not have the setflag or stop - I added them hoping to fix the problem, but no luck. The problem is this: when spam assassin has flagged a message as spam, the sieve runs and the message is in fact filed into the SPAM folder, but no expire entry is added to the database. If I move such a message from the SPAM folder to the Inbox and then back to SPAM, voila, I *do* get the entry created. Here is the mysql table before and after I did the move/move: mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | +----------+---------------+--------------+ 9 rows in set (0.00 sec) mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | | dswartz | SPAM | 1321714666 | +----------+---------------+--------------+ 10 rows in set (0.00 sec) It's almost like the fileinto stuff is not running the plugin code at all, or am I totally on drugs? If I can't get a fix for this, I at least now can think of a hack to "fix" it. e.g. every night, run a script that adds a "now" timestamp for everyone's SPAM folder to trick the periodic expire tool code into checking that folder, but obviously I'd rather have a real fix :) If this is just 'how it works', is it better in 2.0?

[Dovecot] iterate_query not working
by Piotr NetExpert 04 Nov '11

04 Nov '11

Hi, I have got iterate_query defined in dovecot-sql.conf.ext. However when I run a command like: doveadm search -A BEFORE 10d I receive an error message (Failed to iterate ...) There is an error message in a log file too: Error: Trying to iterate users, but userdbs don't support it The problem is that monitoring a database server shows that dovecot does not try to execute any query. What I am doing wrong? password_query lookups work fine. -- pozdrawiam Piotr Szafarczyk http://www.netexpert.pl

[Dovecot] Getting the SMTP envelope through IMAP?
by Hadmut Danisch 04 Nov '11

04 Nov '11

Hi, just a simple question about dovecot: The mbox file format contains the SMTP envelope sender and transmission date in a FROM ... line preceding the RFC822 mail header and body. As far as I see at the moment, the IMAP protocol does not support transmission of that SMTP envelope data in either way, but confusingly uses the term „envelope” for a structure describing the RFC822 mail header. My question is, whether there is any way to retrieve the SMTP envelope through dovecot's IMAP anyway, maybe through some extension. regards Hadmut

We are planning to use a NAS/SAN device using ZFS or EFS for email storage. Each logical unit will be of 10TB and similarly as the no: of user increases we are planning to add multiple 10TB units. In this case how we can manage the email storage on multiple volumes from Dovecot. The configuration of our existing system is:- Dovecot 1.0.15 / Maildirs Postfix 2.5.5 Debian 5.0.9 (Lenny) MySQL 5.0.15 Please advise. Thanks in advance. Creative Regards, Arlin

[Dovecot] looking for Dovecot-code + SQL consultants
by Rich 03 Nov '11

03 Nov '11

Hi, We're using Dovecot2. Trying, given our own spread-too-thin bandwidth, to make it work within our evolving SQL application environment. When there's a problem, we post to this list (e.g., http://www.dovecot.org/list/dovecot/2011-October/061609.html) but aren't getting any/timely responses. We've decided to look for a consultant (hourly or retainer) that can be available for working with our in-house staff to straighten these issues out -- by helping us identify & fix our own mess, and by working to get fixes pushed to Dovecot project code, where appropriate. If you provide these services, rather than simply deployment or hosting, and are available, please drop me a line *offlist*. We're in the San Francisco area, and local is best, but remote work is certainly an option. Thanks, Rich

All the ESXs hosts and all the VM use the same NTP server. Any other idea?

Double check the time also on your host system(s), not only on guest. Bye, gc Il 03/11/2011 11.30, Maria Arrea ha scritto: > We use ntpd daemon, all our systems are configured equal.

We use NTP. Quick check, but by "NTP" you mean the background daemon and you don't have some cron job running ntpdate or similar every so often? No idea, but since it looks like a clock related curiousity, then knowing if the clock is spot on accurate or drifting would be interesting to know? Simple comparison against other machines over a similar period to you having problems might be accurate enough?

Re: [Dovecot] Imap/pop gateway

If you are going to use an imap proxy for security reasons, consider using a software DIFFERENT than in your real mailboxes. If you use dovecot in your backend, you could use perdition in the frontend.

This accepts connections on one machine, examines them until the end of the auth stage and passes them onto some other machine based on the results of the auth process Also there are other imap/pop proxies such as nginx That said I'm not sure how much security this really buys you versus port forwarding POP/IMAP ports to your real server? If the proxy machine were to get hacked (over imap?) then the same hack can jump from the proxy to the real server. Also your only exposure in each case is via POP/IMAP, which means you would be mainly chasing buffer overflow vulnerabilities and the like. These can also be mitigated by chrooting the server machine (please consider virtualisation options, it's usually simpler/faster/saner, eg see my favourite: linux-vservers), MAC controls on the dovecot process (grsec/selinux, etc), and compiler extensions (gcc hardened) Good luck Ed W
