Hello! I want to upgrade the docevot-installation from v 1.0.5 to 2.1..7 Now I get the following executing doveconf -n -c /etc/dovecot/dovecot.conf > /home/mail1/dovecot-2.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:217: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:219: passdb passwd-file {} has been replaced by passdb { driver=passwd-file } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:222: userdb passwd-file {} has been replaced by userdb { driver=passwd-file } The section at line 217 looks like this: auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd } userdb passwd-file { args = /etc/dovecot/passwd } How do I change it to fullfill the new needs?

[Dovecot] auth-worker problem here.
by Marko Weber 07 Jun '12

07 Jun '12

hello, in howto for gentoo i found this: To tell Postfix about the maps that you've just set up, add the following (substituting mysql for pgsql if you're on PostgreSQL) to the bottom of /etc/postfix/main.cf: virtual_alias_maps = mysql:/etc/postfix/sql_virtual_alias_maps.cf virtual_mailbox_domains = mysql:/etc/postfix/sql_virtual_domain_maps.cf virtual_mailbox_maps = mysql:/etc/postfix/sql_virtual_mailbox_maps.cf Tip: Because this is using the Dovecot's LDA, all results from virtual_mailbox_maps are ignored beyond checking if they exist. I added in the mysql db an alias postmaster(a)domainn.tld that should be forwarded to name(a)domainn.tld. The tip above tells me when using dovecot lda the virtual_alias_maps is ignored by dovecot. now when i send a mail to postmaster(a)domainn.tld the mail is not transported to name(a)domainn.tld. in logfile i see this: dovecot: auth-worker: sql(postmaster(a)zbfmail.de): Unknown user how can i tell dovecot to also use the virtual_alias_maps? thank you marko

[Dovecot] Problem with Dovecot and AD LDAP auth
by Алексей Переклад 07 Jun '12

07 Jun '12

Hi. Seems it's a bug in dovecot auth. I have FreeBSD 8.1-RELEASE-p1 and I tried 1.2.17 and 2.1.7 versions of Dovecot, and still no luck. The problem: when I set in dovecot-ldap.conf: base = CN=Users,DC=domain,DC=local everything works fine. But if I set: base = DC=domain,DC=local mail client can't authorize. /var/log/dovecot.log says: =============================================== Jun 07 18:07:17 auth: Debug: auth client connected (pid=14611) Jun 07 18:08:11 auth: Debug: client in: AUTH 1 PLAIN service=imap session=G1//aeLB6wAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55787 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): result: uid missing Jun 07 18:10:18 imap-login: Info: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 127 secs): user=<>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<G1//aeLB6wAKAABu> Jun 07 18:10:18 auth: Debug: client in: CANCEL 1 Jun 07 18:10:18 auth: Debug: auth client connected (pid=14706) Jun 07 18:10:26 auth: Debug: client in: AUTH 1 PLAIN service=imap session=n6IBcuLB7AAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55788 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): Connection appears to be hanging, reconnecting Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): result: uid missing Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): Request lost Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): ldap_search(base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway))) failed: Operations error Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:13:18 imap-login: Info: Disconnected: Inactivity (auth failed, 1 attempts in 172 secs): user=<gateway>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<n6IBcuLB7AAKAABu> ============================================ My dovecot-ldap.conf: =============================== ldap_version = 3 hosts = ad.domain.local base = DC=hrom,DC=local scope = subtree dn = CN=mailserver,CN=Users,DC=domain,DC=local dnpass = here_is_pass auth_bind = yes pass_attrs = uid=user pass_filter = "(&(objectClass=person)(sAMAccountName=%u))" user_attrs = name=mail=maildir:/var/mail/virtual/hrom.local/%n user_filter = "(&(objectClass=person)(sAMAccountName=%u))" =================================================== I need base = DC=domain,DC=local for searching for user's accounts in different OU of my AD. If I set base = CN=Users,DC=domain,DC=local, Dovecot can't authorize user accounts from OU. P.S.: Postfix with base = DC=domain,DC=local works perfectly, so the problem is not with our domain controller (LDAP server as well) .

[Dovecot] Email auto purging applied to all mail folders
by Joe V Aldeguer 07 Jun '12

07 Jun '12

Hello, Is it possible to have this done not only for spam and trash folder but lets say like the user inbox and any user created mail folders too? My ultimate goal is to have a way to automate the email deletion process of emails stored in the user inbox or mail folders when it reaches a specified date. My boss wants to force users to keep emails only a month old anything beyond that will be deleted. Has anyone done this using dovecot and are there any guides available? I am also open to suggestions for commercial solutions but so far searching online for solutions only comes up with email archiving. The dovecot version I have installed is version 2.0.19. Thanks in advance. - Joe

[Dovecot] dsync backup doubles quota
by Patrick Westenberg 07 Jun '12

07 Jun '12

Hi everyone, I recognized a very strange behavior when doing backups of my mdbox mailboxes. After the backup the quota for each mailbox is twice as much as before the backup and I have to recalculate the quota to get the former/correct information. root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - root@mb01:~# doveadm backup -u test(a)example.com mdbox:/home/example.com/test root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 10 10240 User quota MESSAGE 22 - root@mb01:~# doveadm quota get -u test(a)example.com root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - Is this a bug or normal behavior?

[Dovecot] best practises for mail systems
by Костырев Александр Алексеевич 06 Jun '12

06 Jun '12

hello! Can someone point me to some best practices in building high-available scalable mail system or! share your own success stories. I've read article in LJ "Building a Scalable High-Availability E-Mail System with Active Directory and More" but it seemed to be outdated and there's a single point of failure (Master node). What I want to achieve: high-available, horizontaly scalable, with no single point of failure mail solution. Available hardware: intel mfsys25 modular server with 2 storage controllers, 2 switches, 4 power supply blocks with - 2 blade-servers in mfsys with: 2xIntel Xeon E5620 @ 2.40GHz with 8 cores each - promise vtrak e610s (2 storage controllers, 2 power supply blocks) - 6x 2TB SATA Hitachi HDS72302 We decided to go for KVM virtualization and glusterfs for live migration for vm image but that's not what this is all about :) We installed centos on host systems. for now while we could think of two ways to go: The first way (currently at testing stage): On each host system we created one VM and passed through 3x2TB disks into it. In guests vms on top of this disks we made XFS and fired up glusterfs with distributed replicated volumes for our mailstorage. so it looks like this: vm1 replicate vm2 disk1 ------------> disk4 disk2 ------------> disk5 disk3 ------------> disk6 in each vm we mounted glusterfs and pointed dovecot to that dir for mail creation (as ltmp) and imap4 user access. also we use exim as smtp. So, with glusterfs as mailstorage we can go for LVS to load balancing for exim and dovecot. so wherenever one of host systems (hence one of mail vms) goes down, users don't notice that 'cause LVS points them to working smtp and imap4 servers and they get their mail 'cause of glusterfs. Pros: - high-available - horizontaly scalable - with no single point of failure Cons: - not quite sure if glusterfs is production ready solution 'cause I've experienced split-brains during setting it up - IO performance issue. Though we didn't yet run any io tests, but glusterfs uses fuse to mount on clients. And guys on #gluster told me writing to the glusterfs mount will not be strictly local io. The second way: split up the users mail with: two back-end VMs each other on DIFFERENT host system with - fat mailstorage with raid1+linear mode (mdadm)+XFS - dovecot/exim-back-ends and two VMs for nginx-based proxy servers for imap4 and smtp - nginx can redirect user to right back-end through HTTP-php-based logic. Pros: - we split up not only load for exim/dovecot but users mail IOs too - no split-brains Cons: - If one of the host systems (hence one of back-end VMs with storage) goes down, half of our users is unhappy P.S. Sorry if this place is way wrong to ask for such things.

Tripwire? If the purpose of your query is to automate blocking of brute forcers, this software is not what you want (which detects tampering of critical system files). I suggest trying to find where Postfix failed login reports go, then use your fail2ban or what-have-you to detect and block hosts that repeatedly fail authentication.

[Dovecot] INBOX help needed, dovecot + squirrelmail
by jeep＠rahul.net 05 Jun '12

05 Jun '12

Im trying to figure out how to get dovecot to deliver to my mail_location (example: /opt/imapdata/j/jeff/INBOX/inbox) AND work with squirrelmail. Ive worked on this for hours reading the docs etc with no luck so far. I get dovecot-lda to deliver to: /opt/imapdata/j/jeff/INBOX/inbox but when I use squirrelmail, I see the following in the log: dovecot: imap(jeff): Debug: Effective uid=1006, gid=999, home=/opt/imapdata/j/jeff/INBOX/inbox dovecot: imap(jeff): Error: chdir(/opt/imapdata/j/jeff/INBOX/inbox) failed: Not a directory dovecot: imap(jeff): Debug: Namespace : type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/opt/imapdata/j/jeff:INBOX=/opt/imapdata/j/jeff/INBOX:LAYOUT=fs:DIRNAME=mmDIR:INDEX=~/indexes It complains that 'inbox' isnt a directory, but I want it to use: /opt/imapdata/j/jeff/INBOX What parameter do I need to tweak to get this to work? Ive tried the 'folder options' in squirrelmail but that doesnt appear to have any effect here (or at least at this point in my testing). It seems that the only parameter to tweak is 'mail_location' which Im having no luck getting to work correctly. Also namespace may play a part but every combination Ive tried does not result in getting it work thus far. On a sidenote when I send more than 1 email, it doesnt seem to honor 'maildir', it seems its doing 'mbox' instead? I get one flat file. Im lost and confused. my variables: mail_location = maildir:/opt/imapdata/%1n/%n:INBOX=/opt/imapdata/%1n/%n:LAYOUT=fs:DIRNAME=mmDIR:INDEX=~/indexes namespace { type = private separator = / prefix = INBOX/ inbox = yes } Your help is appreciated!

Helo, I'm using Dovecot 2.1.1 with Postfix 2.3.3. I've enabled the quota plugin, so that Dovecot LDA reject e-mails, when user's mailbox is out of space. By default, when mailbox is near quota, and someone tries to send huge message, a reply is automatically send to the sender. It's being send from postmaster named as Mail Delivery Subsystem. And here is my question: Is there some way to customize that auto-reply, so that it is not only being send to the sender but also to recipient gets some notice about failed attempt ? I've also noticed, that this reply has attachment, which is rejected message, but it appears to be empty. Can I configure Dovecot to send back whole rejected message ? Regards malloc4k

[Dovecot] Vacation stopped working
by Jacek Osiecki 04 Jun '12

04 Jun '12

Hi, I'm sure that it WAS working, but I can't guarantee... On a system with dovecot 2.0.16 and dovecot-pigeonhole-2.0_0.2.5. Today a user reported that vacation autoreponse did not work for him. As I have checked the dovecot logs, I see such a message: Jun 04 13:39:51 lmtp(9986, user(a)xxx.com) Info: ZumtCleezE8CJwAAA1GDYg: sieve: msgid=<alpine.LNX.2.00.1206041336520.11397(a)pingwin.sc>: discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers (recipient=<user(a)xxx.com>, and additional `:addresses' are specified) Any idea what actually went wrong? I was browsing for this error message, but found only dovecot sources :( Greetings, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

Something that seems to be missing from this discussion are considerations of privacy and (personal) security. There are fairly serious implications of a sender being able to tell that/when someone has downloaded/opened a message -- including discovery of daily patterns and potentially where the recipient is, or isn't. I think it is our responsibility to understand these issues and explain them to managers/clients in order to bring them along if we refuse (as I would) to provide a capability such as this. [I always set the sendmail "noreceipts" PrivacyOptions so it doesn't respond to these disposition requests.] One approach is to point out to managers/clients that if their system is configured to return read receipts, anyone sending mail to them on that system will be able to get these same types of receipts. When they think about that they may not like the implications and may reconsider their request. Just because it is technically possible to do something (and even if other vendors provide the capability) does not mean that it is the ethically or legally responsible thing to do. - Richard

[Dovecot] Exposing global (default) sieve script through Managesieve
by Matthijs Kooijman 04 Jun '12

04 Jun '12

Hi folks, I'm setting up a dovecot server with managesieve support. I'd like to offer spamfiltering through a Sieve script to my users by default, but still allow them to modify the filtering rules through Managesieve. I found the sieve_global_path configuration option, which seems perfect for what I want. I can configure a default script there, which will work for all users until they set upload their own sieve script using managesieve. However, when configured like this, the user experience isn't quite perfect. When users open the managesieve interface on their client, there is no trace of the default filters, so users might think the spamfiltering is done in some other manner. Now, when they create a filtering rule (e.g., to sort out mail to mailing lists), that rule will overwrite the default spamfiltering rule causing all the spam to spill into the user's mailbox. I'm afraid that most users won't realize they have to manually recreate the spamfiltering rule to fix this. Also, they might not know how to write the rule, even if they do... I've considered a few existing ways to fix this: - Use sieve_before / sieve_after to make sure that the default script is always executed, in addition to any user-supplied scripts. This removes the surprise, but removes the option for users to tweak the spamfiltering rules. - Don't use sieve_global_path, but instead distribute the default script to each user's homedir on user creation. This prevents making changes to the default script for existing users and in my setup, user creation and (mail)homedir creation are nicely separated through an LDAP directory, I'd rather not go this route. - When using the Roundcube webmail application as the IMAP client, I can point Roundcube at the default sieve script. Now, when Roundcube sees there are no scripts through ManageSieve, it shows a (fake) "default" script with the correct contents. As soon as the user changes this script or creates a new script, it is actually uploaded to Dovecot, causing the edited script to be used instead of the global script. This option has the user experience I'm looking for, but having this out-of-band connection from Roundcube to the default script configured with dovecot is ugly (and tricky, since these run on different hosts in my setup). The biggest problem is of course that this only works for Roundcube, not for any other IMAP client my users might use. So, I was wondering: Wouldn't it make sense for the managesieve plugin to do something similar to roundcube: When the user has no sieve script configured, let it fake a single "default" script, showing the contents of the global script? Since the ManageSieve protocol doesn't seem to support any way to flag this situation, it would be fooling the clients a bit, but I'm not sure if that's really a problem. While the user has not script named "default" in his sieve_dir: - include a script called "default" in the LISTSCRIPTS output. - return the contents of the sieve_global_path in the GETSCRIPT "default" command. - remove any sieve symlink after a SETACTIVE "default" command (as if SETACTIVE "" was given). This causes dovecot to fall back to the sieve_global_path script. - the DELETESCRIPT "default" command should fail. This might confuse clients and users, since it is listed in LISTSCRIPTS but cannot be deleted, but I think most users will understand they can't delete the default script. - RENAMESCRIPT "default" "some_name" should copy the sieve_global_path script into the user's sieve_dir. This will effectively copy the script instead of renaming it (since it will still be magically listed in LISTSCRIPTS), so that might be confusing. All other commands work just like they do now (in particular, PUTSCRIPT "default" uploads a script called "default" into the user's sieve_dir, preventing all of the above from applying. As noted above, this change might cause some confusion, but I think that is manageable. On additional thing is that running SETACTIVE "" will not completely disable sieve processing (as would be expected), but will (again) cause the sieve_global_path script to be run. This is already the case currently, though, and should probably be considered a separate problem (whose root cause is the lack of a difference between "no script script configured yet" and "active script disabled", both remove the sieve symlink). Also, this problem might be a feature in some setups, so fixing it might not be so easy... So, any thoughts on this? Any fundamental problems I'm missing? (Not-so) obvious alternatives? Gr. Matthijs

[Dovecot] sieve with dovecot v1.x

Hello! Is there a chance to have sieve working with dovecot version 1.0.5? /usr/lib/dovecot looks like this: -rwxr-xr-x 1 root root 43932 22. Sep 2007 checkpassword-reply -rwxr-xr-x 1 root root 538996 22. Sep 2007 deliver -rwxr-xr-x 1 root root 127728 22. Sep 2007 dict -rwxr-xr-x 1 root root 270248 22.

Sep 2007 ssl-build-param so there is a sievec and a sieved, but in the dovecot.conf there is no mention about sieve. I would compile the latest version of dovecot if I knew, how the running 1.0.5 was built. I need it for an openSUSE 10.3 Kind regards Andreas

[Dovecot] Strange Dovecot 2.0.20 auth chokes and cores
by Alan Brown 02 Jun '12

> From: "Konrad ."<len7hir(a)gmail.com> > When we upgrade our kernels from 2.6.32.2 to 3.2.16 something strange > has happened. > On high traffic dovecot/auth looks like not responding. > > We found a lot of this lines at the log: [snip] > We compile Dovecot with poll instead of epoll (--with-ioloop=poll) and > this works for us. > > > Is any problem with epoll on 3.2.x kernels? Yes - and it's been discussed here. Some "bright spark" rewrote the kernel epoll code to prevent DoS attacks caused by "excessive forking". That "bright spark" clearly doesn't use imap or webserver software. Redhat backported this change to kernels released after February 2012 and are about to release an emergency kernel release which removes it. A number of $LARGE companies were "not happy" As you've posted, compiling without epoll fixes the problem, but that doesn't help anyone using distro or repo packages.

[Dovecot] interesting stats pattern
by Cor Bosman 02 Jun '12

02 Jun '12

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC Anyone have any idea what could cause such a pattern? Maybe dovecot does some cleaning up of idle sessions at specific intervals? Or maybe our loadbalancers do, or the imapdirectors. regards, Cor
