[Dovecot] How do I use a username/password plain text file as authentication backend?
by Angus 26 Feb '11

26 Feb '11

I only have a single user (with multiple mail addresses) and I don't want to expose local users (no pam or /etc/passwd). Using a SQL database seems like overkill to me. So why not just a plain text file? Well, I've read http://wiki2.dovecot.org/PasswordDatabase/Static and related wiki pages, but I just can't find a clear answer. I certainly don't want to allow "any user" or "any password". Dovecot 2.0.9. Any hints for me?

[Dovecot] mail from root rejected

I have dovecot mailserver running well. Everything is fine except that mails from root are rejected (some system processes are sending messages by mail using root as sender). In the logfile i get: Feb 25 10:05:51 Beethoven postfix/qmgr[5228]: 0C7A8652489: from=<root@mydomain>, size=893, nrcpt=1 (queue active) Feb 25 10:05:51 Beethoven postfix/smtp[5662]: 0C7A8652489: to=<hnat@mydomain>, relay=smtp.inode.at[62.99.194.14]:25, delay=0.08, delays=0.04/0/0.02/0.01, dsn=5.0.0, status=bounced (host smtp.inode.at[62.99.194.14] said: 550-Verification failed for <root@mydomain> 550-Unrouteable address 550 Sender verify failed (in reply to MAIL FROM command)) What can i do to have these mails forwarded?

[Dovecot] LDAP and GSSAPI problems
by Trever L. Adams 25 Feb '11

25 Feb '11

This is a continuation of a problem I have been having. Samba 4 has recently changed to require binds. I need LDAP to verify users exist. I am using Kerberos (GSSAPI) as the passdb. Samba can handle GSSAPI/Kerberos SASL binds. I have the following in my dovecot-ldap setup for userdb: dn = smtp/mailhost.example.org(a)EXAMPLE.ORG sasl_bind = yes sasl_mech = GSSAPI sasl_realm = EXAMPLE.ORG sasl_authz_id = smtp/mailhost.example.org(a)EXAMPLE.ORG Which gives me the following error. Debug: ldap(trever): user search: base=dc=example,dc=org scope=subtree filter=(&(objectClass=person)(|(mail=trever)(sAMAccountName=trever)(userPrincipalName=trever))) fields=userPrincipalName dovecot: auth: Error: LDAP: binding failed (dn smtp/mailhost.example.org(a)EXAMPLE.ORG) Local error, SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Credentials cache file '/tmp/krb5cc_97' not found) Additionally, I have "auth_krb5_keytab = /etc/dovecot/krb5.keytab" setup for the GSSAPI user login. The credential cache should be that file should it not? If not, how do I go about setting that up so that it will work.

[Dovecot] Sendmail and Dovecot deliver (dovecot-lda)
by Giles Coochey 24 Feb '11

24 Feb '11

Hi, I have a Centos 5 system with sendmail running as my MTA. Normally I note from sendmail logs that mails get delivered using the 'local' mailer. I have therefore entered the following into my sendmail.mc file, from an earlier post on this list: define(`LOCAL_MAILER_PATH',`/usr/libexec/dovecot/deliver') define(`LOCAL_MAILER_FLAGS',`DFMPhfnu9') define(`LOCAL_MAILER_ARGS',`deliver -d $u') However, when sendmail tries to use deliver I just get this message: Feb 13 15:37:23 gate sendmail[1399]: p1DEWtc2021995: to=<user(a)example.org>, delay=00:04:28, xdelay=00:00:00, mailer=local, pri=121665, dsn=4.0.0, stat=Deferred: local mailer (/usr/libexec/dovecot/deliver) exited with EX_TEMPFAIL I've tried to get better logging by putting the following in 15-lda.conf in /etc/dovecot/conf.d: protocol lda { postmaster_address = postmaster(a)example.org auth_socket_path = /var/run/dovecot/auth-master mail_plugins = sieve mail_location = maildir:~/.maildir log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log } I find nothing gets written to the log file, even if I make it a world writable file. Does anyone have any ideas? What are the best steps to get more information troubleshooting? -- Best Regards, Giles Coochey NetSecSpec Ltd NL T-Systems Mobile: +31 681 265 086 NL Mobile: +31 626 508 131 GIB Mobile: +350 5401 6693 Email/MSN/Live Messenger: giles(a)coochey.net Skype: gilescoochey

[Dovecot] Running dovecot on embedded device?
by Jef Driesen 24 Feb '11

24 Feb '11

Hi, I'm considering buying a QNAP TS-212 NAS and I wonder if this device is powerful enough to run dovecot too (there is a pre-built dovecot package available from QNAP)? The main goal would be that my mail is stored centralized on the NAS, where I can access it from multiple systems without ending up with mail scattered over each system (which is exactly what is happening now due to the fact that my isp offers only POP3). There will only be a few users (e.g. family members), and incomming mail will be fetched from the isp mailbox. The specs of the QNAP TS-212 are: * ARM Marvell Kirkwood 1.2GHz CPU * 256MB DDRII RAM Is this sufficient to run dovecot, and will the performance be acceptable? I'm not expecting something lightning fast, but something that is acceptable. Jef

[Dovecot] Quotas from LDAP
by Sven Hartge 23 Feb '11

23 Feb '11

Hi all! I have been reading http://wiki2.dovecot.org/Quota/Configuration over and over for the last two days, but something totally escapes my brain right now: How does user_attrs = homeDirectory=home,quotaBytes=quota_rule=*:bytes=%$ get the quota from LDAP into dovecot? What are the LDAP attributes used and what does %$ mean? It is not in the variable list at http://wiki2.dovecot.org/Variables I am feeling very stupid and dense right now, as I am absolutely sure I am missing something very obvious and totally simple. Grüße, Sven. -- Sig lost. Core dumped.

Hi, We set up a new mail server and moved users' "cur,new and tmp" folders only into new mail server from old server.In other words we did not copy and paste dovecot.index,dovecot-uidlist,etc into new server from old server because they were created automatically.After bringing the new server up,users(microsoft office outlook) complained their imap folders are missing.I investigated and found below information; I can see those missing imap folders in old server under 'dovecot-uidlist' as follows; [root@mail ~]# vi /var/vmail/abc.com.au/kerrie/ .Deleted Items/ dovecot.index dovecot.index.cache dovecot.index.log dovecot.index.log.2 dovecot-uidlist .INBOX.Air &- Gas/ .INBOX.Amex/ .INBOX.Caltex Starcard/ .INBOX.Creditors NSW/ .INBOX.Creditors NSW.Statements and Invoices/ .INBOX.Creditors QLD/ .INBOX.Creditors QLD.Invoices and Statements/ .INBOX.Debtors/ .INBOX.Export/ .INBOX.Followmont Transport/ .INBOX.Gameco New Zealand/.Junk E-mail/ But in new server,'dovecot-uidlist' is not containing those folders. [root@mail ~]# vi /var/vmail/abc.com.au/kerrie/Maildir/ cur/ dovecot-uidlist .Sent Items/ .Deleted Items/ .Drafts/ subscriptions dovecot.index .Junk E-mail/ tmp/ dovecot.index.cache new/ .Trash/ dovecot.index.log .Sent/ So I want to have those missing folders which are already in old server in new server too.So users can see their disappeared imap folders again.I saw in dovecot wiki,it is not recommended to edit 'dovecot-uidlist' manually.Please give me a solution.Thank you in advance. -- View this message in context: http://old.nabble.com/http%3A--www.linuxquestions.org-questions-showthread.… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Rejected mails

I'm getting closer, now with SMTP permitted to whole of Internet to connect to my SMTP/postfix server & for my postfix server to connect out to public Internet on tcp 25 as well.

[Dovecot] Sharing mails with other users without copying data
by Ernesto Revilla Derksen 22 Feb '11

22 Feb '11

Hello. We would like to share mails without copying the data to another mailbox. The problem is that we use exim4 for delivery and maildir++ format. Would it be feasible to create a symlink or hardlink using the COPY or COPYlike (extension) command? Regards. Erny Ernesto Revilla Yaco Sistemas +34 954 500 057

[Dovecot] [Q] A mix-up between /%d/%u/ and /%d/%n for virtual users
by J4K 22 Feb '11

22 Feb '11

Hi there, I have noticed I misconfigured a dovect 1.2.n server with virtual email. Mistakingly, I used /%d/%u/ for mail_location, but /%d/%n userdb: mail_location: maildir:/var/vmail/%d/%u/ userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes As a result I have maildirs being created for both (e.g): /var/vmail/bigdomain.com/dirk(a)bigdomain.com /var/vmail/bigdomain.com/dirk The actual email is placed in /var/vmail/bigdomain.com/dirk(a)bigdomain.com, which I am happy with. I would liek to tidy up the configuration so that these extra maildirs are not created, without breaking everything. Would someone recommend what the best steps are? (other than reinstalling and starting from scratch - Its in production).

[Dovecot] need help with public namespaces
by Pierfrancesco Caci 22 Feb '11

22 Feb '11

Hello, I need some guidance with setting up a public namespace with per-user \Seen flags. What I want to do is that a group of users access the public namespaces and if user A reads a message, user B should still see it as new until he reads it himself. This is not happening now, and I can't figure out why.

[Dovecot] imap-login ESTABLISHED client sessions not timed out by server
by J4K 22 Feb '11

22 Feb '11

Good morning everyone, I noticed some mobile client connections that I know should have timed out at least 20 mins ago, yet these are still there. The device in question lost its 3G connection and never re-established it. I know, because in this case it was my 'phone ;) Why should the imap-login keep the copnnection in in EST, when it was dropped ages ago. I imagine that the mobile client did not correctly close down the session, but it should have timed out on the server. Any ideas? Has anyone noticed this afore? imap-logi 7819 dovecot 10u IPv4 24069447 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:39042 (ESTABLISHED) imap-logi 7820 dovecot 10u IPv4 24069443 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:52696 (ESTABLISHED) imap-logi 7821 dovecot 10u IPv4 24069536 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:55341 (ESTABLISHED) imap-logi 7822 dovecot 10u IPv4 24069464 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:44647 (ESTABLISHED) Linux fred 2.6.32-cgmemcap-smack #1 SMP Tue Dec 28 14:28:18 CET 2010 x86_64 GNU/Linux Debian Squeeze.

[Dovecot] Problem with ldap / quotas
by Nikolaos Milas 22 Feb '11

22 Feb '11

Hi, I am trying to enable per user quotas, but I get the following error: Feb 18 23:59:20 vmail dovecot: auth(default): ldap(tester,10.10.100.150): ldap_search((uid=tester)) failed: No such object It seems as if ldapsearch for username/password won't work with my new settings, but I can't find why. I run Dovecot v1.2.11 on CentOS 5.5. I changed my working dovecot.conf (see later) with the following changes (I used the roomNumber attribute to store the quota value): 1. Added in main part: mail_uid = 500 mail_gid = 500 2. Changed userdb with: userdb ldap { args = /etc/dovecot-usrdb-ldap.conf } and /etc/dovecot-usrdb-ldap.conf is: hosts = localhost tls = no base = ou=people, dc=example, dc=com scope = subtree ldap_version = 3 auth_bind = yes user_filter = (uid=%u) pass_filter = (uid=%u) pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=example,dc=com user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u 3. Changed passdb with passdb ldap { args = /etc/dovecot-passdb-ldap.conf } where /etc/dovecot-passdb-ldap.conf is identical to dovecot-usrdb-ldap.conf. What am I doing wrong? Please advise.

[Dovecot] Dovecot doesn't show any e-mails, while there are a lot in the maildir
by Attila Nagy 22 Feb '11

22 Feb '11

Hi, I've recently seen the following issue. A user logs in with pop3, and sees zero e-mails. The maildir contains emails both in cur and new. The mail delivery is done with qmail, and this user have had no logins before, so it has only the inbox, trash and sent (while dovecot is configured to create drafts and spam folders too). Because of this, the user doesn't have any dovecot indexes either. So, he logs in, and sees nothing. The strange thing is Dovecot doesn't create any of the above directories nor indexes. After moving the mailbox to another server, the user can log in, the additional folders get created and also the indexes appear. pop3 shows the correct amount of emails. Moving the mailbox back to the original server shows the same issue: no emails at all. Restarting dovecot on the original server resolves the issue. This is a pretty loaded machine, so I couldn't trace the processes. I know that this isn't too much, but that's what I have. The only thing I could identify in the error log is: Feb 17 12:45:58 pop3(varszr@asdfg): Warning: Created dotlock file's timestamp is different than current time (1297943148 vs 1297943086): /home/varszr@asdfg/Maildir/subscriptions Which may happened due to a restart and maybe a clock setting. But that was yesterday.

[Dovecot] [PATCH] Add Install section to dovecot.service, so it can be used independently from dovecot.socket
by Mike Kazantsev 22 Feb '11

22 Feb '11

Good day, Dovecot includes nice unit files for systemd, but I've noticed that "systemctl enable dovecot.service" fails because service file does not include Install section. I assume that is because there's a .socket file, but there might be reasons when you want to enable it as a service. In my case it's one of the main services on the machine, so I'd like to see whether it's started correctly in systemctl after boot. And of course I don't want it to be killed due to "no connections timeout" at any given time. Plus, it provides authentication info for postfix daemon running on the same machine, and dovecot.socket does not handle this case. Following patch allows dovecot.service to be enabled via usual systemctl command.

[Dovecot] dovecot permission problems
by Calvin23 22 Feb '11

22 Feb '11

Hello, I'm trying to make a dovecot installation run on my freeBSD 8.1 server, since quite a long time now, and I can't figure out how to solve my last problem. I did quite a lot of searching and many people seem to have the same problem, but I didn't manage to make any solution work on my host. So I would be glad for every hint :-) I'm using postfix with dovecot. Everything works just as expected, except one little permission problem. When dovecot tries to deliver a mail to my homedir everything is working out. I use fdm to connect to my server to download the mails, and here is where things stop to work: Here some logs: http://pastie.org/1579465 Here my dovecot -n output: http://pastie.org/1579489 I really tried a huge amount of different things, redesigned my whole configuration file from scratch etc. Does anybody has an idea how I could fix this little last problem I have here? If you need more information, please don't hesitate to ask, I wasn't sure what I should provide and didn't want to spam too much ;) With best regards, Calvin23 -- View this message in context: http://old.nabble.com/dovecot-permission-problems-tp30960767p30960767.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Rewrite the mailbox copy functions works in imap but don't work in doveadm import command
by Alex Baule 22 Feb '11

22 Feb '11

Hi Timo !! I rewrite the copy function from mailbox (using a plugin) My rewrite is like this: static int emexis_antispam_copy(struct mail_save_context *ctx, struct mail *mail){ struct mailbox *box = ctx->transaction->box; union mailbox_module_context *zbox = EMEXIS_CONTEXT(box); struct mail_private *_mail = (struct mail_private *)mail; union mail_module_context *zmail = EMEXIS_MAIL_CONTEXT(_mail); struct istream *input; const char *headerFile; char *bodyFile; int fd; int increment; ......Do some stuffs and verifications OK.... // GETTING THE FILE TO READ SOME STUFF FROM HEADER. if (zmail->super.get_stream(mail, NULL, NULL, &input) >= 0){ i_warning("GET STREAM COPY OK..."); }else{ i_warning("GET STREAM COPY NOT OK..."); } // REALLY COPY EMAIL copyret = zbox->super.copy(ctx, mail); } OK, when i use the IMAP , using a client and copy a email, it's works fine. But, when i use a doveadm import command, the part "(zmail->super.get_stream(mail, NULL, NULL, &input) >= 0)" fails, with no error message, only a segfault.... doveadm[14980]: segfault at 9c ip b7698000 sp bf83d7d0 error 4 in libdovecot.so.0.0.0[b7663000+6d000] doveadm[14983]: segfault at 9c ip b7661000 sp bf9c9ee0 error 4 in libdovecot.so.0.0.0[b762c000+6d000] doveadm[14986]: segfault at 9c ip b75b3000 sp bfcd82e0 error 4 in libdovecot.so.0.0.0[b757e000+6d000] doveadm[14989]: segfault at 9c ip b7684000 sp bfa5d3c0 error 4 in libdovecot.so.0.0.0[b764f000+6d000] There is difference between imap using a client , and doveadm import command ? If have some difference, can i identify and do some workarround ? Tks Timo !!

Some more info: I am running dovecot 2.0.9 on Red Hat Enterprise Linux 5 Another question I would like to ask: I run the command doveadm import as "entrega" user (see dovecot -n output in my previous mail ). If I run the command as root also segfaults, and garbage is restored (mails with binary data). If I run as "entrega" segfaults, but e-mails are correctly restored Regards Maria.

[Dovecot] Best way to migrate versions and machines
by Donny Brooks 21 Feb '11

21 Feb '11

We are looking to migrate from our current mail server running dovecot-1.2.11-3 to a new mail server running the latest dovecot (2.0.9?). So this would not only be a version change but also a machine change. We currently use Maildir for storing mail and would like to stay that way. Has anyone preformed such a feat and it worked? Looking for any input.

[Dovecot] Segmentation fault running doveadm import

Hello.

[Dovecot] Regenerating mdbox/sis
by dmiller＠amfes.com 21 Feb '11

21 Feb '11

It's apparent I have some level of corruption in my mailboxes - something to do with the combination of mdbox, sis, and zlib. I should note that I know I have a mix of compressed and raw messages - if that makes any difference in identifying the problems. I think I need to somehow regenerate the mailboxes with issues. Is there a suggestion for how to accomplish this? Should I perhaps use dsync to shift to a temporary mail location and then rename it back? If I DO use dsync in this manner, and I have zlib enabled - will this then compress all the messages in the new mail storage? -- Daniel

[Dovecot] IMAP flags not being committed properly?
by Janos Barbero 21 Feb '11

21 Feb '11

I'm afraid I can't give steps to reproduce this, but if someone's come across something like this, it might help me figure out what's going on. I run imapfilter/offlineimap to fetch mail from a gmail to a local maildir store, which I then access with alpine via dovecot (1.2.15). Here's the output of dovecot -n: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian squeeze/sid ext3 log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/data/1/mail:LAYOUT=fs mbox_write_locks: fcntl dotlock mail_plugins: fts fts_squat auth default: passdb: driver: pam userdb: driver: passwd plugin: fts: squat Just recently, I went through a bunch of old unread messages, marking them as read (in alpine). When I selected all unseen messages in pine (;sn), 18 showed up. But the count was higher within Gmail even after an expunge and offlineimap sync. So I selected all seen messages (;s!n) and marked them all as seen (a*!n). This didn't take long (for a 30k message folder) but surprisingly enough came back with the notice that 15 messages were marked as seen, and sure enough, at the next offlineimap sync, flags were updated on 15 messages. So I didn't touch anything in gmail, everything went to the maildir through dovecot via alpine, and then back to gmail via offlineimap. Yet the select command obviously did not return all the matching messages. Anyone know what's going on? Thanks, Janos

[Dovecot] dsync problem: Error: Can't rename mailbox INBOX
by Jan Binder 20 Feb '11

20 Feb '11

Hi all, I'm running two debian machines with dovecot 2.0.9 autobuilds and would like to keep mails synchronized on both via dsync. Mails are kept in maildir on both sides. While syncing, dsync gives the following error: dsync-local(jan.binder): Error: Can't rename mailbox INBOX to INBOX_a432bf2eca595a4dba47000043b078f4: Renaming INBOX isn't supported. dsync-local(jan.binder): Error: Can't rename mailbox INBOX_e184273887675a4dcc5b00000c16d079 to INBOX: Target mailbox already exists Further diagnostic information: dsync command: dsync -D -v -f mirror ssh jan.binder(a)firefly.local dsync dovecot -n on firefly.local: # 2.0.9 (159605040ec0): /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-trunk-686-bigmem i686 Debian wheezy/sid 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 { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } dovecot -n on depth.local: # 2.0.9 (049a922c193c): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian wheezy/sid 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 { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Should this usage of dsync work in principle?

[Dovecot] Maildir folders, separator = /, LAYOUT=fs (to support offlineimap)
by kkruzich 18 Feb '11

18 Feb '11

I use offlineimap to pull down some Gmail mail stores. With offlineimap I use sep = / and nothing more exotic. With dovecot I can see INBOX, messages, and messages in top level folders but not subfolders. I'm dealing with folder structure that looks like this: /opt/gmail/joe/Later /opt/gmail/joe/Tech/Projects /opt/gmail/joe/Tech/Projects/Fun /opt/gmail/joe/Tech/Projects/Failed /opt/gmail/joe/Tech/Projects/Planning The folder Later has cur, tmp, new and I can see messages. Projects is a container for subfolders Fun, Failed, Planning. I know Fun, Failed, Planning has messages but I'm not able to expand (via thunderbird) the folder Projects. I have this configured in dovecot.conf mail_location = maildir:/opt/gmail/joe:INBOX=/opt/gmail/joe/INBOX:LAYOUT=fs namespace private { separator = / list = yes } --- And this is what's getting logged... dovecot: Feb 18 07:26:39 Info: IMAP(joe): Namespace: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes dovecot: Feb 18 07:26:39 Info: IMAP(joe): maildir: data=/opt/gmail/joe:INBOX=/opt/gmail/joe/INBOX:LAYOUT=fs dovecot: Feb 18 07:26:39 Info: IMAP(joe): fs: root=/opt/gmail/joe, index=, control=, inbox=/opt/gmail/joe/INBOX

[Dovecot] Upgrading Dovecot v1.0.10 -> v2.0.9
by Jackie Hunt 17 Feb '11

17 Feb '11

Hi all, OK, I admit it. I've seriously neglected our Dovecot installation. I installed version 1.0.10 in Jan 2008, and it has been a great workhorse since then. It has run like a champ, so it was ignored due to higher priority projects. But now it is time to get current with Dovecot, and I really need your help. We are using the mbox mailbox format. First so I want to upgrade to 2.0.9, since it looks like that is the latest version? It looks like development is still happening on the 1.x line, so do I need to get to the 2.x line? Any comments/suggestions/recommendations on that? I know there are major changes from 1.x -> 2.x.. Also, do I need to go through incremental upgrades? I'm guessing changes have been made to the index files and the dovecot configuration. Do those need to be done in steps, or can I made a major leap forward? I'd appreciate any input on this project. I need to start planning. Thanks so much! Jackie

[Dovecot] Problem with messages with long lines
by ZMA - Emiliano Mariño 17 Feb '11

17 Feb '11

Hello dear mailing list readers, Recently I am experimenting a problem trying to retrieve messages over a POP3 protocol. Everything goes right until the POP3 client tries to retrieve a message that contains one or more long lines lines as long as 3000 characters or even more. The client (Outlook 2003 and 2007) stops on that message until timeout. I have opened a connection manually to see what happens, and when I issue the RETR command on one of these messages, dovecot informs the message size and then nothing else. No message sending. Any other message works fine; I get the message size and next the message itself. I have upgraded to version 2.0.1 but I still get the same behavior. No error is reported on the server side. Logs indicate that everything is just fine. Any advice on how to solve this would be very appreciated.

[Dovecot] Dovecot + Exim + Maildir quota problem
by Matteo Tinazzi 17 Feb '11

17 Feb '11

Hi all i'm a new user of this list, i got a server with DirectAdmin which has exim as MUA, dovecot as POP/IMAP server, recently i added the quota to exim and pointed the maildirsize file in the same location if the dovecot's one so both services can interact with it. This has been done to let exim update the quotas while doing localdelivery while dovecot can show quotas through roundcube and update them when users delete mails. The issue that i noticed is that some users get wrong quota informations... after a little investigation i think it could be a concurrent access to this file so dovecot tries to remove the deleted mails fomr maildirsize and exim tries to put new ones inside. In a specific case i got a user with a quota of 50M seeing that 75% of his quota filled while the real weight of the mail files is about 4% ... any help would be very appreciated

[Dovecot] Dovecot 2.0.9/1.2.11: crash in driver-pgsql.c
by dovecot＠excellency.fr 17 Feb '11

17 Feb '11

Hello, I finally took time to isolate and reproduce a long time Dovecot crash that is bugging me since at least Dovecot 1.0.x. It's still there in Dovecot 2.0.9, which I just tested. Here is the backtrace from my logs: Feb 16 16:56:57 dovecot: auth: Error: pgsql: Query timed out, aborting Feb 16 17:25:16 dovecot: auth: Panic: file driver-pgsql.c: line 349 (result_finish): assertion failed: (db->io == NULL) Feb 16 17:25:16 dovecot: auth: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7fdbfe6d4272] -> /usr/lib/dovecot/libdovecot.so.0 [0x7fdbfe6d42d6] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fdbfe6d46c8] -> dovecot/auth [0x42f555] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xdd) [0x7fdbfe6df9bd] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x5e) [0x7fdbfe6e05be] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7fdbfe6df618] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fdbfe6cd883] -> dovecot/auth(main+0x2d4) [0x419474] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7fdbfc4f91a6] -> dovecot/auth [0x40da09] Feb 16 17:26:35 dovecot: master: Error: service(auth): child 140263 killed with signal 6 (core not dumped) Both my userdb and passdb use a PostgreSQL database. The bug happens when the PostgreSQL host suddenly becomes unavailable. I can easily reproduce it by launching Dovecot with my host being up, and then null routing its IP address (to simulate an outage): route add -host 10.0.0.2 reject (10.0.0.2 being the IP address of the PostgreSQL host.) >From that point, if I try to authenticate (using a POP3 connection, for instance), dovecot-auth will crash one or two minutes later. In Dovecot 2.0.9, despite the crash, authentication will resume once the PostgreSQL is back up (which can be simulated with: route delete -host 10.0.0.2 reject). In Dovecot 1.x however (latest version I tested is 1.2.11), it will stay in this state forever (logs are flooded with Password query failed: Not connected to database.)

[Dovecot] Cannot subscribe to shared folders
by Lukas Haase 17 Feb '11

17 Feb '11

Hi, I am unable to subscribe to shared folders with Thunderbird although everything seems to be correct (dovecot 1.2). What does not work? I click "Subscribe..." in Thunderbird. The shared mailboxes are listed, all with [ ] (no checkbox). Therefore I mark them [x], click "subscribe" and "OK". However, the folders do not appear in the folder tree. Furthermore, when I again click "Subscribe..." the folders do NOT have the mark [x] any more. This happens on different computers with *new* profiles. My configuration is the following (maybe that is the problem?!): namespace private { separator = . prefix =. inbox = no list = no hidden = yes location = maildir:~/Maildir-root subscriptions = yes } namespace private { separator = . prefix = INBOX. inbox = yes subscriptions = yes } namespace public { separator = . prefix = Shared. location = maildir:/var/mail/shared:INDEX=~/Maildir/shared:LAYOUT=fs subscriptions = no } The folder /var/mail/shared has appropriate permissions/form: * Owner: $user:mailuser (all users are member of "mailuser") * All files 0660, all folders 0770 * There exists a dovecot-shared in every folder * There exists a dovecot-acl in each folder where each user has the permissions "lrwstie" I switched on "mail_debug = yes" but no messages. However, the file ~/Maildir-root/subscriptions contains the subscribed folders: Shared.Group1 Shared.Group2 Shared.Group1/Test Furthermore, I switched on rawlog. Everything seems to be OK as well: .in-file: 2 subscribe "Shared.Group1" 3 lsub "" "INBOX.*" 5 lsub "" "Shared.*" 6 list "" "INBOX" .out-file: 2 OK Subscribe completed. [...] I am pretty sure it already worked. But it stopped working. Does anybody have a hint what could be the problem? Regards, Luke

[Dovecot] Some questions about mdbox
by Maria Arrea 16 Feb '11

16 Feb '11

Hello I am starting testing with dovecot 2.0.9. In my //etc/dovecot/dovecot.conf/ I have the following line: /mail_location = mdbox:/mydomain.org/%2.26Hn/%2.200Hn/%n:INDEX=/mydomain.org/indexes/%2.26Hn… These are my questions (a long mail): *1º How should I restore from backup with mdbox & separate indexes?* I have read in dovecot list archive about restoring the full user mailbox to a temp location and then run something like: /doveadm import mdbox:/tmp/restored_mailbox/ "" savedsince 2011-01-01 / In my schema indexes and mail stores are in separated paths. What (and where!) should I copy to the temp location and how do I restore it? *2º Disaster recovery: indexes & mail store mismatch* When creating backups, indexes and mail store are in different paths. My backup takes several hours, so indexes are copied BEFORE mail stores. Is the backup consistent? What would happens if I lose indexes? Can I still recover the messages? Reading the doc it seems I would lose all the message flags and all the messages would be in INBOX, is this right? *3º Performance tuning with mdbox* I have read in dovecot archive about using mdbox_rotate_size & mdbox_rotate_interval to balance between a lot of smaill files (like Maildir) or really big files (a "variant" of mbox). I have tested with a big vaule of mdbox_rotate_size (100 MB) and is a complete disaster for backup:if a user delete a message, then a nightly cronjob purges the mailbox (refcount=0) a new mdbox .m file is created!. So deleting a 1 k message from the mailbox of an user is a new 99 MB file to backup. Any hint about this? I am also using ext4 (rw,noatime,nodiratime,commit=15,data=writeback) and I have read about mdbox_preallocate_space. I will try it, any hint about this setup? This is not still in production, so I have no idea about IOPs and user concurrency, but I have several thousand users. *4º Compression with mdbox* I am reading about compression in mdbox (zlib/bzlib). I am starting with zlib, has anyone experience with bzlib? How much load is bzlib against zlib and how much delay adds to user experience (and space savings vs zlib???) ? *5º Recover a message with refcount=0* Is there any way to recover a message with refcount=0 without using a backup? I am thinking about the following plan: /1º a user gets her mail via pop3 (or delete a message via imap and empties trash) 2º the message is still stored in my mail server, but has refcount=0 3º nightly backup is performed 4º nightly cronjob purges the mailbox (deleting messaged with refcount=0)/ Using this schema the backup is bigger, but If I can recover files with refcount=0 from backup we can give our users a safeguard against accidentaly deleted pop3 mail. Thank you very much for your responsed and sorry for my (awful) english! Maria

I have tested with a big vaule of mdbox_rotate_size (100 MB) and is a complete disaster for backup:if a user delete a message, then a nightly cronjob purges the mailbox (refcount=0) a new mdbox .m file is created!. So deleting a 1 k message from the mailbox of an user is a new 99 MB file to backup. Any hint about this? I am also using ext4 (rw,noatime,nodiratime,commit=15,data=writeback) and I have read about mdbox_preallocate_space. I will try it, any hint about this setup? This is not still in production, so I have no idea about IOPs and user concurrency, but I have several thousand users. *4º Compression with mdbox* I am reading about compression in mdbox (zlib/bzlib). I am starting with zlib, has anyone experience with bzlib? How much load is bzlib against zlib and how much delay adds to user experience (and space savings vs zlib???) ? *5º Recover a message with refcount=0* Is there any way to recover a message with refcount=0 without using a backup? I am thinking about the following plan: /1º a user gets her mail via pop3 (or delete a message via imap and empties trash) 2º the message is still stored in my mail server, but has refcount=0 3º nightly backup is performed 4º nightly cronjob purges the mailbox (deleting messaged with refcount=0)/ Using this schema the backup is bigger, but If I can recover files with refcount=0 from backup we can give our users a safeguard against accidentaly deleted pop3 mail. Thank you very much for your responsed and sorry for my (awful) english! Maria

[Dovecot] Auth processes/login processes count
by Thomas Hummel 16 Feb '11

Hello Timo, I'm running dovecot-1.2.12/Maildir/LDAP-passdb/LDAP-prefetched-userdb and I'm experiencing "random" latency (which even seem to make squirrelmail timeout sometimes) at login without noticing particular load on the server. LDAP backends are running fine as far as I know so I was investigating maybe mistuned limits : Dovecot is configured (for ~3000 users) with . each login processed in its own process : #login_process_per_connection = yes #login_max_connections = 256 . counts as : #login_processes_count = 3 login_max_processes_count = 1024 auth default { [...] count = 5 } I've got several questions : 1) how can I count more than login_max_processes_count processes ? # ps aux | egrep -i '(pop3|imap)-login' | wc -l # 1031 2) could be my auth process count the bottleneck ? is there a rule of thumb to deduce it from the login process count ? 3) on dovecot login/master/auth design, is my understanding correct ? - dovecot-1.2.x : . passdb and userdb lookup are done by the auth process, on behalf of either the login process which wants to know if the client's password is correct or of the master process which wants to check if it was actually correct and which wants to have the userdb info. . client connection fd is sent to the master which creates the mail process and transfers the fd to it. - dovecot-2.x : . client connection fd does not go through the master anymore but through a socket in the login/ directory . it's the mail process which ask the auth process for the userdb lookup 4) with LDAP backend using {CRYPT} passwords dans with plaintext auth enabled in dovecot, is the clear password crypted before comparing it to the LDAP crypted password or does dovecot try to simply bind to LDAP with the clear password ?
