[Dovecot] How do I do this with mdbox?
by Odhiambo Washington 29 Jan '11

29 Jan '11

In my life with Maildir, mails were stored as single files, each mail per file. It was pretty easy to resend an e-mail from a Maildir folder to another address, by causing the mail to be re-injected into my MTA (Exim) queue for processing: I'd use a very simple shell script to achieve the above: #!/bin/sh email=$(find $*) { for x in ${email}; do sendmail president(a)egypt.gov < ${x}; done } Now, with mdbox container/storage, it beats me how to achieve the same. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] Sharing user folders doesn't work when users have periods in names.
by ian+dovecot＠comtek.co.uk 28 Jan '11

28 Jan '11

I am using period as an IMAP separator with Maildir directories and I cannot share folders where the user has a period in their name. Suppose I log in as 'some.user' and do: SETACL INBOX mailtest(a)example.co.uk +lrwstipekxacd /var/mail/virtual/users/some.user/Maildir/dovecot-acl is created, with appropriate contents and shared-mailboxes.db gains an entry for 'shared/shared-boxes/user/mailtest@example.co.uk/some.user@example.co.uk'. mailtest is simply unable to see a new folder. As mailtest 'a LIST "" "Users.*" ' is empty. If I do ' a MYRIGHTS Users.some.user.INBOX ' I get 'NO [NONEXISTENT] Mailbox doesn't exist: Users.some.user.INBOX' and, oddly, a new maildir appears: '* LIST (\Noselect \HasChildren) "." "Users.some" ' -- it also creates an empty folder structure with a single file /var/mail/virtual/users/some/Maildir/dovecot-acl-list too! Is there a workaround that does not involve rebuilding every user's Maildir with backslash as a separator? Thanks, Ian

[Dovecot] Dovecot2 + Sieve

Hi, i'm new on sieve, but want to use ist with sogo. The Problem is, that when i set a redirect or vacation rule like: redirect "email(a)example.com"; (real Adress is different) the sieve says the mail would be forwarded, but no mail is sent. (No Action in /var/log/maillog) And because there is no Error-Message it's difficult to search for... Dovecot log ------- Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: using sieve path for user's script: /var/mail/vhosts/test/.dovecot.sieve Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: opening script /var/mail/vhosts/test/.dovecot.sieve Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: script binary /var/mail/vhosts/test/.dovecot.svbin successfully loaded Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: binary save: not saving binary /var/mail/vhosts/test/.dovecot.svbin, because it is already stored Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: executing script from /var/mail/vhosts/test/.dovecot.svbin Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Info: sieve: msgid=<4D429227.3000004(a)pilarkto.net>: forwarded to <email(a)example.com> ----- Everything else works fine, except the program "mail". I dont know if there is a coherence but a typical Mailserver-Test "date|mail -s test email(a)example.com" also don't sent a message to postfix. I hope you will held me out or even say me, if this is a bug or a misconfiguration. thanks a lot Philipp

[Dovecot] dovecot ACL

Hi in Dovecot 2.x with virtual domains, is there a way specify what domains can create shared directories and who can't? For example I have 3 domains, domain1.com, domain2.com and domain3.com. Let's say I only want domain1.com's users to create shared folders how can I go about doing this. Thanks, Paul

[Dovecot] Telnet access creates new maildir folders
by Seasoul 28 Jan '11

28 Jan '11

Hi, I am running Dovecot Version 1.0.15on a Debian server, with postfix and postfixadmin. My mailbox base is /var/mail/vmail When I send an email to a user1(a)domain.com for the first time, the user "mail" creates a set of dovecot folders under /var/mail/vmail/ user1(a)domain.com/ and my new emails are found in /var/mail/vmail/ user1(a)domain.com/new When I test my server using telnet (telnet domain.com 110), I can log in fine as a user1, but when I type "LIST", it tells me there are no emails. And I realize a new set of dovecot folders were created under /var/mail/vmail/user1/ ! The folders are created by the user "user1". Obviously the folder "new" under that is empty, since my emails received are in /var/mail/vmail/user1(a)domain.com/new and not /var/mail/vmail/user1/new . Therefore, connecting with an email client via POP also shows an empty inbox. I am lost as to what to do to fix this, and how to let the server know that pop access should be looking into /var/mail/vmail/user1(a)domain.com/ instead of /var/mail/vmail/user1/ . Hopefully someone on this list will be able to save me from my misery :) Cheers Sea

[Dovecot] Best way to calculate concurrent users?
by Henrique Fernandes 28 Jan '11

28 Jan '11

Well, i am having some problens to figure out how many concurrent users into the server! In my envoriment now, most people are using the webmail interface, and it just conect and disconct pretty quickly so i can not get it with "doveadm who" doveadm who only gets the ones that are connect with clients. O use ipvs to balance betwaeen 2 servers does anyone have an ideia ? With ipvs i get this results: IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP XXX.XX.X.XX:143 lblcr -> 10.0.2.10:143 Masq 1 16 228 -> 10.0.2.11:143 Masq 1 16 184 There is others ports and stuff. Does any one have an ideia how to get this number ? []'sf.rique

[Dovecot] Storing Dovecot index files on sql
by list＠airstreamcomm.net 28 Jan '11

28 Jan '11

We have been communicating with the mailling list on another thread regarding dotlocking on the dovcot-uidlist over an NFS share, and I was hoping to get some ideas on whether or not a sql database would be a suitable location for storing the dovecot index files. Our though process so far has been that storing the index files on NFS with the maildir has not worked very effectively when we are using multiple Dovecot servers (even using sticky IPs in our load balancer), and using local storage is not possible with a cluster of machines, so we got to thinking about what type of storage platform would be suitable for these index files that would provide native locking of the data while multiple servers accessed and wrote to it. Our question to the community is whether sql storage for index files has ever been considered, what issues would this introduce, and if it's even feasible? Thanks everyone! Michael

[Dovecot] Differenft INBOX for IMAP/POP with checkpassword passdb
by Peter Mogensen 27 Jan '11

27 Jan '11

Hi, I'm trying to do a setup where IMAP and POP users see different INBOX' Like described on the virtual folder wiki page: http://wiki.dovecot.org/Plugins/Virtual However, for now, I'm stuck with the checkpassword passdb and prefetch userdb So I can't parameterize the result on %s like the example with MySQL does. So I thought of having to different checkpassword scripts: passdb checkpassword { args = /usr/bin/checkpassword-%s } However, Dovecot (1.2.15) doesn't seem to expand %s even though the Wiki says it should be available everywhere: http://wiki.dovecot.org/Variables Is this a bug, or am I missing something. /Peter

[Dovecot] Best Cluster Storage
by Jonathan Tripathy 27 Jan '11

27 Jan '11

Hi Everyone, I wish to create a Postfix/Dovecot active-active cluster (each node will run Postfix *and* Dovecot), which will obviously have to use central storage. I'm looking for ideas to see what's the best out there. All of this will be running on multiple Xen hosts, however I don't think that matters as long as I make sure that the cluster nodes are on different physical boxes. Here are my ideas so far for the central storage: 1) NFS Server using DRBD+LinuxHA. Export the same NFS share to each mail server. Which this seems easy, how well does Dovecot work with NFS? I've read the wiki page, and it doesn't sound promising. But it may be outdated.. 2) Export block storage using iSCSI from targets which have GFS2 on DRBD+LinuxHA. This is tricky to get working well, and it's only a theory. 3) GlusterFS. Easy to set up, but apparently very slow to run. So what's everybody using? I know that Postfix runs well on NFS (according to their docs). I intend to use Maildir Thanks

[Dovecot] Questiosn about dbox
by Javier de Miguel Rodríguez 26 Jan '11

26 Jan '11

Hello I have read carefully about dbox (/http://wiki2.dovecot.org/MailboxFormat/dbox/) and I have some questions: - One of the main advantages (speed wise) of dbox over maildir is that index files are the only storage for message flags and keywords. What happens when we want to recover some messages from backup? With maildir we can rebuild message indexes, but I am not sure about dbox. Should we also restore "old indexes" and merge with the "new indexes" in order to restore the deleted messages? - The previous question applies to sdbox and mdbox. In the case of mdbox, we can configure rotation of files using /mdbox_rotate_size/ . We would like to rotate daily, not based in size (our users ask us for yesterday's backup). How can we accomplish this? We have now 17.000.000 messages in our maildir, almost 1.5 TB (zlib compresssion enabled). Our backup time with bacula is rather bad: 24 hours for a full backup, most of the time the backup is busy fstat'ing all those little messages. We think that mdbox can help us in this. Does anybody has good experiences migrating from maildir->mdox in "large" enviroments? What about mdox performance & reliability? Thank you for your support Javier

[Dovecot] authentication methods : pam, passwd and then backup question. How to restrict the methods
by J4K 25 Jan '11

25 Jan '11

Dear all, I noticed that incoming users were attempting to authenicate using several methods like pam sql. Eventually, they logged in. Is there a way for dovecot to only query a mysql backup for users, and skip the other methods? Examples from logs (via Roundcube webmail in this case, but the same messages appear with port 993) Jan 25 17:22:17 srv dovecot: auth-worker(default): pam(aa(a)bb.co.uk,127.0.0.1): pam_authenticate() failed: Authentication failure (password mismatch?)

The distribution is Debian Squeeze. Regards, s

[Dovecot] shared namespace subscription

I test dovecot 2.0.9 and i use a shared namespace. I use this to see inbox for user2 in shared namespace for user1. When user2 unsubscribe for inbox , the shared inbox disapear too from shared namespace in user1 list. This is normal ? I believe that whatever subscription has user2 , if the director is shared , only the indexes will be copyied from the original place, not along with the subscription.

[Dovecot] custom maildir location mapping
by Vlad Mazek 25 Jan '11

25 Jan '11

Greetings, I'm migrating from a sendmail/dovecot setup with system users to a postfix/dovecot maildir setup with virtual users. To simplify the mess we've gotten into by having users that can't remember their username, we've switched to email address being the username. In order to allow for a smooth migration, I need to allow users to be able to login with their email address as well as their (old) username for about a month or so. I have all the usernames, email addresses and passwords stored in SQL and I'm generating the userdb and passworddb manually. Is there any way to create a userdb and passworddb so that users can login with either username or email address and have dovecot locate their maildir without an issue? For example, I'd like to be able to login as either vlad or vlad(a)vladville.com and have dovecot locate my maildir:/var/spool/mail/%d/%n; I'd really appreciate any thoughts, ideas and examples anyone is willing to share. I'm really looking to avoid a shotgun approach ("On Feb 1, your new username is your email address"). Here are some notes on the currently functioning setup: I'm running dovecot 1.0.7 on CentOS 5.5 x64 with Postfix 2.3.3 mail_location = maildir:/var/spool/mail/%d/%n userdb static { args = uid=virtual gid=virtual home=/var/mail/%d/%u } passdb passwd-file { args = /etc/dovecot/passwd } user@domain.com:{HMAC-MD5}1b05f379...

[Dovecot] PAM problem with virtual domain/user ownership
by Mauricio Tavares 25 Jan '11

25 Jan '11

I am running dovecot 1.2.9 (ubuntu package, not from source) and wanted to use pam to authenticate my mail users who have no local accounts. I've done that before in an earlier release of dovecot and ubuntu, so I would not need to do set dovecot to ask LDAP directly. So, I have in dovecot.conf: # Authentication processes mechanisms = plain login passdb pam { args = "*" } userdb static { args = allow_all_users uid=virtual gid=virtual home=/var/spool/vmail/domain.com/%n } i.e. /var/spool/vmail/domain.com/ is owned by virtual:virtual, drwxr-x--- 4 virtual virtual 4.0K 2011-01-23 11:45 domain.com and that is how I would hope dovecot would be trying to login as. When I tried to login as user raub, the log file seems to tell me that it is trying to create /var/spool/vmail/domain.com/raub/cur as raub:users, not as virtual:virtual Jan 22 06:35:02 mail dovecot: imap-login: Login: user=<raub>, method=PLAIN, rip=216.155.101.90, lip=216.155.101.94, TLS Jan 22 06:35:02 mail dovecot: IMAP(raub): mkdir(/var/spool/vmail/domain.com/raub/cur) failed: Permission denied (euid=5016(raub) egid=100(users) missing +w perm: /var/spool/vmail/domain.com) What am I missing here?

[Dovecot] SSD drives are really fast running Dovecot

I just replaced my drives for Dovecot using Maildir format with a pair of Solid State Drives (SSD) in a raid 0 configuration. It's really really fast. Kind of expensive but it's like getting 20x the speed for 20x the price. I think the big gain is in the 0 seek time. Here's what I bought.

[Dovecot] How to enable COPY and APPEND commands separately
by Alex Cherniak 24 Jan '11

24 Jan '11

I'd like to allow a user to move messages between his folders on Dovecot IMAP account, but prevent move/copy from different accounts (Exchange in particular). Outlook uses "xx UID COPY 1 folder" and then "xx UID STORE 1 +FLAGS (\Deleted \Seen)" for internal moves and "xx APPEND folder" for external ones. I tried to achieve this with ACL, but i (insert) seems to control both. Do I miss something? Should I look somewhere else? Please help.

[Dovecot] Dovecot Update on Ubuntu from 1.0.10 to 1.2 doesn't work
by franc walter 24 Jan '11

24 Jan '11

Hello, i have an ubuntu 8.04 LTS Virtual Server with Dovecot 1.0.10 and postfix. Now i tried to update Dovecot because i need Quota, which is not possible in 1.0 but in 1.2 So i added the packages to my /etc/apt/sources.list: deb http://codex.xiaoka.com/apt hardy main restricted deb http://archive.ubuntu.com/ubuntu hardy-backports main universe multiverse restricted and updated dovecot with aptitude. After this i killed the proc master and restarted postfix and dovecot but now dovecot is running but doesn't get any more mails from postfix. I had to downgrade back to 1.0.10 and after this all is working again. I immediately looked into the mail.log, but i didn't see any clear errors. I uploaded the mail.log here, maybe someone could give me a hint, what it could be: http://7fw.de/tmp/2011-01-24-23-38-mail.log I started the update at 2011-01-23 at 23:00 and downgraded back at 2011-01-24 at 00:26. In the error.log i only have errors about inotify, which is not available on the ubuntu server (old kernel version, cannot be updated by provider). I set in dovecot.conf: mail_debug=yes auth_debug=yes auth_debug_passwords=yes but this didn't help me. Thank you, Kind regards, franc walter

[Dovecot] Using dsync+imapc for migration from other IMAP servers to Dovecot
by Timo Sirainen 24 Jan '11

24 Jan '11

Dovecot v2.1 hg (http://hg.dovecot.org/dovecot-2.1) now supports doing e.g.: dsync -o plugin/imapc_user=remote.user(a)example.com -o plugin/pass=remote-password mirror imapc:imap.example.com dsync will preserve message UIDs and UIDVALIDITY/UIDNEXT values for mailboxes, just like with all other storage backends. A couple of bad things: 1) It currently fetches one message at a time from server. Very slow.. Will be fixed some day. 2) You can't do incremental sync, because dsync relies on message GUIDs, which aren't available in IMAP protocol. This could be fixed some day. Also a support for Dovecot extension could be added some day to make this work for Dovecot as remote IMAP server.

[Dovecot] Does dsync handle client-side deletions?
by Patrick Schoenfeld 21 Jan '11

21 Jan '11

Hi there, I'm currently evaluating the idea of a multi-master setup where each node shall hold a full copy of the mailboxes. Basically the idea is to use NFS and dsync to keep those copies in sync. So I did some tests with dsync and ran into a problem. Consider the following scenario: 1) Location1 and Location2 are in sync 2) A mail gets deleted on Location1 (via IMAP) 3) dsync mirror run to sync the two locations Expected behaviour: dsync notices that the mail was deleted on Location1 and also deletes it on Location2 to get the locations in sync. What I experience, however, is: dsync notices that the mail is missing on Location2 and copies it from Location1 to get the locations in sync. (At least) In debug mode it will spit a warning: dsync(test2): Info: INBOX: highest_modseq changed: 8 != 11 dsync(test2): Info: INBOX: Couldn't keep all uids dsync(test2): Info: INBOX: Ignored 1 modseq changes dsync(test2): Warning: Mailbox changes caused a desync. You may want to run dsync again. Now the question is: Doesn't dsync handle deletions or is there something I missed? Dovecot version is 2.0.9. Thanks in advance and best Regards, Patrick

[Dovecot] utility to update indexes ?
by Jan-Frode Myklebust 21 Jan '11

21 Jan '11

We have both dovecot and a webmail application that are both modifying our users maildirs, so dovecot indexes can be out of sync when the webmail has been messing with the maildirs. We also have a webservice that report how many unread messages a user has in his inbox, which is simply counting files in the maildirs (plus caching the result, and present old values if the directory timestamps hasn´t changed). I think this checking of unread messages webservice would be much nicer on the filesystem if it instead used the dovecot indexes, so I created a small utility based on utils/idxview.c that do that: http://blag.tanso.net/code/unread.c But this woun´t work if the maildir has been modified outside of dovecot (i.e. webmail usage). Are there any simple interface I can use in this short snippet for noticing that the index is out of sync, and update it ? -jf

[Dovecot] LMTP & home, chroot, mail userdb fields.
by Lev Serebryakov 21 Jan '11

21 Jan '11

Hello, Dovecot. I'm using postfix + dovecot with pure virtual users. postfix uses standard virtual transport, and dovecot fetches such fields from userdb: chroot: "/usr/home/hosted/v-mail/%d/%n" home: "/" mail: "maildir:." Everything works Ok -- dovecot founds users' mail. Now, after upgrade to dovecot2, I want to use it LMTP server as virtual_transport in postifx. I've changed virtual_transport setting to "lmtp:unix:/var/run/dovecot/lmtp". dovecot's LMTP can not deliver messages, because it seems that it uses userdb fields in some OTHER way. Errors look like this: Jan 20 12:19:25 lmtp(38939): Info: Connect from local Jan 20 12:19:25 auth: Info: mysql: Connected to /tmp/mysql.sock (mailhost) Jan 20 12:19:25 lmtp(38939, lev(a)domain.com) Error: mkdir(./cur) in directory /var/run/dovecot failed: Permission denied (euid=30000(v-mail) egid=30000(v-mail) missing +w perm: ., euid is not dir owner) Jan 20 12:19:25 lmtp(38939, lev(a)domain.com) Error: Opening INBOX failed: Mailbox doesn't exist: INBOX Jan 20 12:19:25 lmtp(38939, lev(a)domain.com) Error: mkdir(./cur) in directory /var/run/dovecot failed: Permission denied (euid=30000(v-mail) egid=30000(v-mail) missing +w perm: ., euid is not dir owner) Jan 20 12:19:25 lmtp(38939, lev(a)domain.com) Info: XXVtE00oOE0bmAAAWL5c8Q: msgid=unspecified: save failed to INBOX: Internal error occurred.

[Dovecot] Feature request - statistics for the COMPRESS imap protocol
by Ed W 21 Jan '11

21 Jan '11

Unless I have failed to read the manual for the second time in two days (?), it doesn't seem to be possible to get COMPRESS statistics at logout time from the IMAP protocol? Assuming not, then can I make a feature request that this might become available in some future version (pretty please?) Can I also just check that the meaning (as of today) of the "imap logout" statistics "%i/%o", presumably they refer to bytes over the wire, ie they are the compressed data sizes? Thanks - Dovecot 2 adds a fantastic bag of new features! Ed W

[Dovecot] Delivered-To header without +extension ?
by Per Jessen 21 Jan '11

21 Jan '11

I'm running postfix 2.6.2 and dovecot 2.0.9, and I've just switched to delivering mails to dovecot via lmtp. It looks like the Delivered-To: header is slightly different - it doesn't seem to include the +extension? Is this intentional or does the +extension somehow get in the way? /Per Jessen, Zürich

[Dovecot] Fwd: Re: Dotlock dovecot-uidlist errors / NFS / High Load
by list＠airstreamcomm.net 21 Jan '11

21 Jan '11

Stan, Thanks for the reply. In our case we have actually already done most of the work you suggested to no avail. We had rebuilt two new ntp servers that sync against two stratum 1 sources, and all our nfs clients, regardless of using dovecot, sync to those two machines. You bring up the difference between bare metal and hypervisor, and we are running these machines on vmware 4.0. All the vmware knowledge base articles tend to push us towards ntp, and since we are using centos 5.5 there are no kernel modifications that need to be made regarding timing from what we can find. I will give the ntpdate option a try and see what happens. I was also hoping to understand why the uidlist file is the only file that uses dotlock, or if there was plans to give it the option to use other locking mechanisms in the future. Thanks again!

In a clustered server environment, _always_ run a local physical box/router ntpd server (preferably two) that queries a set of external sources, and services your internal machine queries. With RTTs all on your LAN, and using the same internal time sources for every query, this clock drift issue should be eliminated. Obviously, when you first set this up, stop ntpd and run ntpdate to get an initial time sync for each cluster host. If after setting this up, and we're dealing with bare metal cluster member servers, then I'd guess you've got a failed/defective clock chip on one host. If this is Linux, you can work around that by changing the local time source. There are something like 5 options. Google for "Linux time" or similar. Or, simply replace the hardware--RTC chip, mobo, etc. If any of these cluster members are virtual machines, regardless of hypervisor, I'd recommend disabling using ntpd, and cron'ing ntpdate to run once every 5 minutes, or once a a minute, whatever it takes to get the times to remain synced, against your local ntpd server mentioned above. I got to the point with VMWare ESX that I could make any Linux distro VM of 2.4 or 2.6 stay within one minute a month before needing a manual ntdate against our local time source. The time required to get to that point is a total waste. Cron'ing ntpdate as I mentioned is the quick, reliable way to solve this issue, if you're using VMs. -- Stan

[Dovecot] Populating mailbox dir
by Mauricio Tavares 20 Jan '11

20 Jan '11

Let's say you created a (virtual) mail user but have not created the user mail directory. When you first try to access it, the mail directory is created and populated: ls -a /var/spool/vmail/domain.com/raub/ . dovecot.index.log dovecot-uidvalidity.4d375a39 tmp .. dovecot-uidlist new .Trash cur dovecot-uidvalidity subscriptions Who populates/creates the initial files and folders in the user mailbox? Dovecot? The mail client accessing it through imap? Elvis? If dovecot, is there a way to customize it a bit, so a few extra folders will also be thrown there?

[Dovecot] domain stripping
by PA 20 Jan '11

20 Jan '11

Hi, using dovecot 2.0 and I'm using a couple of user DBs, sql/prefetch and pam. Currently if the user logins with username@domain it authenticates off the sql DB and works fine. If the user logins with username with no @domain it fails on the sql lookup and succeeds on the pam user DB. However I was wondering if I can have another sql DB lookup that says when the user logins and fails against the first two user DBs, sql/pam db, to try this last sql user DB and appends a default domain to it, because the sql DB lists username with the domain. Currently I have all users login in with no realm on the older mail server and I wanted to migrate these users to dovecot 2.x with minimal impact and wanted to have the ability for these virtual users to login with and without a realm. Thanks paul.

[Dovecot] Bug found, assertion failed
by Tobias Daucher 20 Jan '11

Hi there, We're running dovecot 2.06, with mdbox. Following message was in our syslog: Jan 20 09:26:48 servername dovecot: [ID 583609 mail.crit] imap(user): Panic: file istream-limit.c: line 79: assertion failed: (v_offset <= lstream->v_size) The problem could be solved on client side, by just deleting the ImapMail-Folder in Thunderbird. Why? Thunderbird tried to move a message, that obviously wasn't there. Dovecot got killed and the message above was in the syslog. Connection was closed and Thunderbird told me the server is dead. Thunderbird tried this every few seconds, and there was no way to say thunderbird "stop try moving". So the only way was to delete thunderbirds mail cache. I think it would be very nice, if dovecot doesn't die, just because the client tries to move a message, which isn't there.

GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

[Dovecot] Problem with seeing mail after Upgrade from Courier
by apettitt 19 Jan '11

19 Jan '11

I created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no issues. The issue I'm having now is that Dovecot is not seeing any mail in the user's directory. If I create a new user, it can send and receive mail with no problems. If I send an email to an existing user, it gets delivered to the new folder but dovecot does not see anything in the new folder. There is also mail in the curr folder that dovecot does not see. I'm using Roundcube as a webmail client but I've also tried using Telnet with the same results. Any ideas? -- View this message in context: http://old.nabble.com/Problem-with-seeing-mail-after-Upgrade-from-Courier-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)
by Darek M 19 Jan '11

19 Jan '11

Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install. - If I set a forward for an account to go to a remote email address, no dupes. - If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address. So if account1(a)domain.com has account2(a)domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message. I will also get a duplicate if I forward mail to account(a)anotherdomain.com, where anotherdomain.com is also hosted on the same system. account1(a)domain.com receives one copy. Here is the Dovecot log: Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here. This is the entry for the account in the 'alias' table ======================== mysql> select * from alias where address='account1(a)domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1(a)domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 | Anyone have an idea of what I should be looking at in a situation like this? Does the 'goto' field look fine? -- Darek

Hi there, I changed postfix to pass email to spamassassin, and then deliver to dovecot LDA. It fails to deliver. The current entry in master.cf now reads: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} smtp inet n - - - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=nobody argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} This is the same as I had to afore I factored in spamassassin. The error message is this:- Jan 18 16:30:44 logout postfix/pipe[28952]: 56AE58230A: to=<test(a)test.info>, relay=dovecot, delay=0.01, delays=0/0/0/0.01, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] ) Does anyone know which options I should have added to dovecot deliver?

[Dovecot] v2.0.9 released
by Timo Sirainen 18 Jan '11

18 Jan '11

http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz.sig I'm still lagging behind in my email, but I guess it's time to release v2.0.9 anyway. - Linux: Fixed a high system CPU usage / high context switch count performance problem - Maildir: Avoid unnecessarily reading dovecot-uidlist while opening mailbox. - Maildir: Fixed renaming child mailboxes when namespace had a prefix. - mdbox: Don't leave partially written messages to mdbox files when aborting saving. - Fixed master user logins when using userdb prefetch - lda: Fixed a crash when trying to send "out of quota" reply - lmtp: If delivering duplicate messages to same user's INBOX, create different GUIDs for them. This helps to avoid duplicate POP3 UIDLs when pop3_uidl_format=%g. - virtual storage: Fixed saving multiple mails in a transaction (e.g. copy multiple messages). - dsync: Saved messages' save-date was set to 1970-01-01.
