[Dovecot] deliver rewrites envelop-sender
by Ralf Becker 10 Jan '07

10 Jan '07

Hello, we are currently using sendmail, procmail, uwimap and qpopper. We are planing to replace uwimap and qpopper with dovecot. Which seems to be a very good idea :-) But: Sendmail and Procmail will not be replaced. Now I've realized that deliver rewrites existing "From <....> ..." header lines to ">From <...> ..." and adds it's own "From "-line. Example: -------- My procmailrc end with :0 | deliver -d beckerr Mails are deliver to my INBOX, but * From beckerr(a)fh-trier.de Sun Jan 07 17:37:43 2007 * Received: ... * From: ... is rewritten to * From MAILER-DAEMON Sun Jan 07 17:37:44 2007 * > From beckerr(a)fh-trier.de Sun Jan 07 17:37:43 2007 * Received: ... * From: ... Is there a (simple) way to prevent deliver from doing so? OR In case "-f <envelop sender>" is not given, could deliver 1) read the envelop sender address from the "From <...>" line, 2) remove the line and 3) add it's own using the formally extracted sender address? This sounds best for me and would cover the problem most effective... BTW: I've found the "dovecot deliver patch for procmail" and it looks really good (http://dovecot.org/pipermail/dovecot/2006-July/014656.html) but it seems to me, that the "From " line problem is solved by optionally removing the whole line, so deliver would use it's own default "From MAILER-DAEMON "-line ... and this in fact the problem Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] Disable TLS on port 143?
by Jackie Hunt 09 Jan '07

09 Jan '07

Hi all, Is there a way to disable the TLS support provided by Dovecot on port 143? I'd like to run SSL on 993, so as far as I can tell I can't use ssl_disable, since the will disable SSL. I'm looking for the equivalent of an ssl_disable_tls setting. Thanks much, Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] [minor] stale auth-worker sockets
by Luigi Rosa 09 Jan '07

09 Jan '07

I was fooling around the /var/run/dovecot directory and I noticed a lot of stale auth-worker.xxxxx sockets, probably left there by unexpected termination of old versions of Dovecot. Just to know who does what, have I to clean up the stale sockets, or a future version of Dovecot will get rid of this unused sockets?

[Dovecot] dovecot rc7 assert, core
by Jeff A. Earickson 09 Jan '07

09 Jan '07

Hi, Wow, I haven't had an assert/core in dovecot in a long time. Here goes: Setup: Solaris 10, dovecot built with gcc 4.1.1, imap and imaps only. User's home directory lives on a ZFS filesystem, but I don't think that makes a difference. So does every other user here (>3K). Assert: IMAP(mulepri): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) gdb backtrace and other poking at the core is attached.

[Dovecot] Automatic mail script?
by Andreas Andersson 08 Jan '07

08 Jan '07

Hello! I am setting up a Dovecot mailserver for around 2000 people with: sendmail + dovecot + squirrelmail + spamassassin and some plugins. I have the Imap quota working in mboxes with this quota commands: plugin { # 10MB quota limit quota = dirsize:storage=10240 } It worked good in Squirrelmail, but the person that only use some imap program (outlook, eudora) don't get the info when theirs account will be full of mail. So can someone give me a good script for a automatic mail. I want to send a mail to a user when they are nearly exceeded their limits, so they can start cleaning theirs account. Are this possible or how should I solve this problem? /Andreas

[Dovecot] trouble debugging
by Aaron Solochek 07 Jan '07

I want to switch away from bincimap, and I am having some trouble getting dovecot up and running. Something isn't working (I suspect it's a permissions problem) but the logs aren't really telling me anything interesting. I can authenticate and get a list of folders, but when I try to select a folder, I get the "Internal error" message that tells me to check the server logs.

[Dovecot] postfix + dovecot auth problem.
by subscriber＠viliar.net.ru 05 Jan '07

Hello All! I use postfx 2.3.5 + dovecot (pop3/imap/lda/auth daemon for postfix) rc15. root@post /etc/postfix# grep dovecot main.cf smtpd_sasl_type = dovecot virtual_transport = dovecot dovecot_destination_recipient_limit = 1 root@post /etc/dovecot# grep password_query dovecot-sql.conf password_query = SELECT mail as user, cryptp as password, CONCAT('/home/vmail/',homedir,'/',maildir,'/') as userdb_home, uid as userdb_uid, gid as userdb_gid, CONCAT('dirsize:/home/vmail/',homedir,'/',maildir,'/',':storage=',quota/1024) as userdb_quota, nice as userdb_nice, hosts as allow_nets FROM users WHERE mail = '%u' and access = 'Y' and %Ls = 'Y'; When I insert allow_nets (and it should be used without userdb_ prefix) into password_query I could not send any more letters. In logs next: Dec 19 11:25:30 post dovecot: auth-worker(default): sql(mail(a)example.com): query: SELECT mail as user, cryptp as password, CONCAT('/home/vmail/',homedir,'/',maildir,'/' ) as userdb_home, uid as userdb_uid, gid as userdb_gid, CONCAT('dirsize:/home/vmail/',homedir,'/',maildir,'/',':storage=',quota/1024) as userdb_quota, nice as userdb_nice , hosts as allow_nets FROM users WHERE mail = 'mail(a)example.com' and access = 'Y' and smtp = 'Y'; Dec 19 11:25:30 post dovecot: auth-worker(default): passdb(mail(a)example.com): allow_nets check failed: Remote IP not known As I understand, postfix does not transfer to dovecot auth daemon rip ( remote ip ). And it is looks like allow_nets it is impossible to use together with dovecot sasl auth in postfix. Do we have any workaround on it?

[Dovecot] Failed proxy auth drops connection for IMAP/POP3 proxy in 1.0-RC15
by Bruce Walter 05 Jan '07

05 Jan '07

Hello, I was seeing an odd behavior in a proxy-only configuration of dovecot. When a user entered an incorrect password in either IMAP or POP3, the Dovecot connection would be immediately dropped, sometimes with the auth failure message, sometimes without (a timing issue). I believe I have tracked down the cause to the code commented out in the attached diff. It appears that the proxy handlers are giving the client the go-ahead to attempt authorization again and then dismantling the proxy session. I believe the correct behavior would be to allow LOGOUT or QUIT to end the session and do the tear-down in client_destroy. The commented code all gets executed (with more error checking) in client_destroy, so there shouldn't be any memory leaks that I can see. Please advise if this seems correct or let me know of a different method of fixing. Thunderbird does 'Bad Things (tm)' when the connection is dropped without an authorization failed message... It doesn't re-prompt for the password and the user appears to have correctly authenticated, but the session just sits and no mail can be retrieved.

[Dovecot] Getting "Can't resolve address no: Name or service not known" error when starting Dovecot

Hi gentlemen! After running for six month Dovecot 0.99.14 I decided to upgrade to 1.0rc15. Actually Dovecot is running under Slackware Linux 10.2 and I got the package from http://www.linuxpackages.net. Problems? Yes, one! When I try to startup Dovecot program hung: Fatal: Can't resolve address no: Name or service not known I'm not a Dovecot or IMAP guru and I can't imagine what kind of address number (I think is complaining about the machine's IP address) or "name" or "service" that it doesn't know! I googled for the entire afternoon for someone that meet the same problem but I got no interesting clues... Yesterday I installed also iptables and I thought the two things are related so I disabled iptables but... nothing! Here some valuables (I hope!) informations for the good guys that want to help my desperate soul... Thank you again and I hope everybody enjoy the Christmas holidays... Bye!

[Dovecot] deliver as LMTP server?
by Barry Warsaw 05 Jan '07

05 Jan '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 One other question; has anybody considered writing a tool that integrates Dovecot's deliver script and an LMTP server? I'm architecting my system so that my internet facing SMTP is Postfix, but the mail folders live on a different machine. Right now, I'm considering putting a highly restricted Postfix on the internal machine, which only accepts forwards from the external machine. IWBNI I could eliminate that extra Postfix process by just letting the external one deliver to an LMTP on the internal machine, which was integrated with Dovecot's deliver. Does anything like that exist? I have a reasonably robust Python LMTP server in the current Mailman trunk. Would it be insane to try to marry that with deliver? ;) - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRZC95XEjvBPtnXfVAQJgDQP+PxNPZ2453Bb8poBbwtgKAZjwmAJnX4L3 SzipzaoEE8/P8oj/sRwwRO19ViTPmXGZTgQQTF8ipqNL2YAL73QlyeLypzu0ZBBi WyplPkgFlgMeS5rnk9ibyejerO+JdsZt6zKnyKDqdhnhVsgTwvzMsNlu6MaWqtl8 fXPd5Gur6+M= =HGgh -----END PGP SIGNATURE-----

[Dovecot] Problems with dovecot-sieve on Debian Etch using dovecot LDA

[Dovecot] file descriptor leak?
by Steven F Siirila 04 Jan '07

04 Jan '07

We are having problems with the latest Dovecot 1.0 (RC15) regarding file descriptors > 255 being handed off to fdopen() via crypt() via PAM(?). This is a problem on Solaris 10 due to the fact that the stdio library does not support file descriptors > 255 (in order to remain binary-compatibile with older binaries). Here are the messages we run into if we get too many (~250?) concurrent IMAP/POP sessions: Jan 3 13:03:14 hostname dovecot-auth[5799]: crypt: fdopen(265) failed: Too many open files Jan 3 13:03:14 hostname dovecot-auth[5799]: crypt: fdopen(265) failed: Too many open files Jan 3 13:03:15 hostname dovecot: auth(default): pam(username,10.1.1.1): Child process died Jan 3 13:03:15 hostname dovecot: auth(default): PAM: Child 5799 died with signal 11 Questions: 1) Is there a file descriptor leak, or are there supposed to be this many open pipes in dovecot-auth? (master dovecot has way more than 256 at this point, but apparently does not use stdio.) 2) Has anyone tried compiling Dovecot in 64-bit mode (-xarch=v9)? I have tested the fact that this removes the >255 fd limitation in Solaris 9/10. 3) Has anyone even run into this problem on Solaris? I imagine anyone with more than 250 or so simultaneous IMAP/POP sessions would have had to run into it by now. 4) Anyone have any suggested workarounds (besides compiling in 64-bit mode)? We have upwards of 4500 simultaneous IMAP connections alone on some of our servers (running UW IMAP still), so we obviously need to address this problem before we can fully deploy dovecot in our environment. -- Steven F.

[Dovecot] Too many open files
by Daniel Cox 04 Jan '07

04 Jan '07

I am running Dovecot 1.0rc15 on NetBSD 3.1 with only a few connections. It is built from pkgsrc-2006Q3, with mail/dovecot/ updated to HEAD. kqueue is a default build option - I haven't tried without yet. Mail directories/indexes are on a Linux 2.6.16.29 NFS file system, I have set these options and it performs well: mmap_disable=yes lock_method=fcntl FYI. rc7 had very high CPU use with the same options, which rc15 seems to have fixed :-) I also have this problem with dovecot-nightly-20060225 (1.0beta3) on NetBSD 2.1RC3 using a local ffs file system. This appears in /var/log/maillog: Jan 4 18:44:42 server dovecot: pipe() failed: Too many open files # ps ax|grep dovecot 723 ?? Ss 2:14.15 /usr/pkg/sbin/dovecot 822 ??

I haven't worked out how to make this happen automatically on restart. NOTE: hard never goes above kern.maxfiles which is 1772 (I think the kernel needs to be recompiled to increase further). proc.21494.rlimit.descriptors.soft = 1024 proc.21494.rlimit.descriptors.hard = 1772 # fstat -p 21494 root dovecot 21494 45* pipe 0xcc4e0138 <- 0xcc4e0648 rn Shows an increasing number of pipe files open. This NetBSD 3.1 system is a test server which I can experiment with if there is anything further I can do to help find the problem. Thank you, Daniel.

[Dovecot] Custom login_greeting per virtual server?

Just a quick question, nothing broke. I setup about 5 virtual servers. It's great! I can define which protocols to listen on per server. Just curious why I can specify a unique "login_dir" per server, but not a unqiue login_greeting? Appears dovecot always shows the first login_greeting from the first virtual server.

[Dovecot] customizable idle login timeouts?

We're in the process of migrating from mbox over to maildir. I'm running into a problem with the proxy and timeouts. Appears the idle timeout is set to 60 seconds. This is a bit too low for some of our large mbox files :( Any plans on adding the: #define CLIENT_LOGIN_IDLE_TIMEOUT 60 #define AUTH_REQUEST_TIMEOUT to the .conf file to be tunable on the fly? I ended up just patching the couple of files in question, but it'd be nice.. Cassidy

[Dovecot] Urgent - Setup DoveCot with Plesk
by iSquareOne LLC 03 Jan '07

03 Jan '07

Hey, all, I am trying to setup DoveCot with Plesk. But I could not go through the last step. Setup: MySQL 5.0.22 Qmail Plesk 7.5 DoveCot v1.0 RC15 The problem: I setup sql.conf for user query and password query. I tried different ways, DoveCot always says "Authentication failed". Here are my two SQLs. user_query = SELECT concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as home, concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as mail, 101 AS uid, 12 AS gid, 'dirsize:storage=1000000' AS quota FROM accounts a, mail m, domains d WHERE a.id = m.account_id AND d.id=m.dom_id AND m.mail_name='%n' AND d.name='%d' I manully fill in %n=admin and %d=test.com to test it and it worked fine The result is: home,mail,uid,gid,quota "/var/qmail/mailnames/test.com/admin","/var/qmail/mailnames/test.com/admin","101","12","dirsize:storage=1000000" password_query = SELECT concat(m.mail_name, '@',d.name) as user, a.password as password, concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as userdb_home, concat('maildir:/var/qmail/mailnames/', d.name, '/', m.mail_name) as userdb_mail, 101 as userdb_uid, 12 as userdb_gid FROM accounts a, mail m, domains d WHERE a.id = m.account_id AND d.id=m.dom_id AND m.mail_name='%n' AND d.name='%d' The result is: user,password,userdb_home,userdb_mail,userdb_uid,userdb_gid "admin(a)test.com","password","/var/qmail/mailnames/test.com/admin","maildir:/var/qmail/mailnames/test.com/admin","101","12" I don't know what DoveCot is expecting to get from the SQL result.

[Dovecot] Error reading configuration file
by Justin Pearce 03 Jan '07

03 Jan '07

Good day, I seem to be having an issue using dovecot 1.0 rc15. I compiled the source with the following configure command: CPPFLAGS="-I/usr/local/include/mysql" LDFLAGS="-L/usr/local/lib/mysql" -lmysqlclient" ./configure -with-mysql -with-sql-drivers=mysql Did make and make install and set the dovecot-example.conf to dovecot.conf and tried running the program and got the following error: Error: Error in configuration file on line 50: expecting '=' Line 50 of the default config is a comment, which struck me as odd. So, I uninstalled and tried building with no options. I did a make uninstall, removed the /usr/local/lib/dovecot directory did make and make install and tried the program. This time it didn't crash about the config file, but the mail.err log notes that the child processes died on an error 89, apparently unable to figure our what pam was. I'm wondering why the thing seems to work if I do not build for mysql but if I want mysql, it breaks in the manner it does? Is it a bug, or am I doing it wrong (which is a real possibility). Any help soon would be appreciated, as my boss keeps asking 'So, when is that mail server going to be done?'. :) Justin Pearce Information Technology/Programming Price Video Productions JustinP(a)PriceVideo.com 361-572-3810 800-733-3810 Fax: 361-572-3894 www.PriceVideo.com

[Dovecot] DvCot/PstFix Virtual Domains Virtual Users PAM Authentication - How pls
by Kyle 03 Jan '07

03 Jan '07

Hi Folks, I'm hoping some one can set me straight here please. Postfix 2.1.5 Dovecot 0.99.11-2 I have Postfix set up on a new box with Virtual Domains and Virtual Users using MailDir format with their mail homes in /var/spool/mail/<domain>/<user> I want Dovecot to login using PAM Authentication. The idea is to host multiple domains which each have multiple aliases which resolve to one email account for their respective domain but using a user name which actually _is_ a system user. So I might have; jo(a)abc.com joe(a)abc.com joey(a)abc.com pete(a)abc.com peter(a)abc.com jo(a)xyz.com joe(a)xyz.com joey(a)xyz.com pete(a)xyz.com peter(a)xyz.com where 'joe' and 'peter' are both system users each with mail homes of; /var/spool/mail/abc.com/joe /var/spool/mail/abc.com/peter /var/spool/mail/xyz.com/joe /var/spool/mail/xyz.com/peter In my dovecot.conf, I have; auth_userdb = static uid=89 gid=89 home=/var/spool/mail/%d/%u auth_passdb = pam If I login with just 'joe', I get; Fatal: chdir(/var/spool/mail//joe) failed with uid 89: Not a directory Fair enough, that sounds logical to me. But if I then login with 'joe(a)abc.com', I get; PAM: pam_authenticate(joe(a)abc.com) failed: Authentication failure So it appears Dovecot is checking PAM for 'joe(a)abc.com' rather than just 'joe'. How can I make it check for just 'joe' please? -- ------------------------------------------------------------------------ Kind Regards Kyle

[Dovecot] configured mechanisms don't work
by Eggert Ehmke 03 Jan '07

03 Jan '07

Hi, I am new to this list and to dovecot. Forgive me if I ask long discussed items. I managed to install postfix and dovecot 1.0.rc15 on a Debian Sarge server out of the backports. It works so far, I can send emails via smtp to postfix, they are stored in the virtual mailboxes of some users, and I can get them via IMAP from dovecot. However, in dovecot.conf I configured mechanisms = plain login digest-md5 cram-md5 when I connect to the server via telnet 143, I get this: 2 CAPABILITY * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS LOGINDISABLED 2 OK Capability completed. So I can't authenticate using cram-md5. What may I be missing? Regards & happy new year! Eggert

Is there a way to configure logging to indicate what connection type was used to authenticate? I'd like to be able to tell from the logs whether the user used STARTTLS on port 143 or an SSL-wrapped connection on port 993. Using RC15 with auth_verbose=yes gives us the following log entries during login and logout (lines wrapped for convenience): # login port 143 with STARTTLS: Jan 3 14:17:24 tony dovecot: [ID 107833 local5.info] imap-login: Login: user=<glenn>, method=plain, rip=10.0.0.2, lip=192.168.1.2, TLS Jan 3 14:17:41 tony dovecot: [ID 107833 local5.info] IMAP(glenn): Disconnected: Logged out # login port 993/SSL Jan 3 14:19:11 tony dovecot: [ID 107833 local5.info] imap-login: Login: user=<glenn>, method=plain, rip=10.0.0.2, lip=192.168.1.2, TLS Jan 3 14:19:20 tony dovecot: [ID 107833 local5.info] IMAP(glenn): Disconnected: Logged out Turning on auth_debug=yes added some additional info, but I still wasn't able to tell what port or connection type was used.

[Dovecot] "Not connected to database" MySQL errors

I've been in the process of moving my pop3 proxy over to the dovecot proxy. I have a ton of users using pop3 still, and am seeing these errors popup within a minute or so of the connection to the database: Password query failed: Not connected to database Eventually the auth-worker will reconnect to the database and things will go on normal for another minute or two, then the same issue occurs. I'm runing MySQL 5.0.22 on FreeBSD 6.1. I upgraded to 5.0.27, however I started getting the: "Password query failed: Commands out of sync; you can't run this command now" error instead. So I downgraded until I could figure out this issue first. I've tried connecting to localhost, /tmp/mysql.sock, and a remote server and all exhibit the same problem. The MySQL idle timeouts shouldnt come into play because I'm constantly having users check their accounts. Any insights will be useful, Thanks!

[Dovecot] Dovecot and Mail.app
by Barry Warsaw 03 Jan '07

03 Jan '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm trying to convert a courier-imap installation over to using Dovecot, but I'm having some problems with Mail.app on OS X. FTR, we use both Mail.app and Thunderbird. Note that in the Mail.app preferences, I have a blank IMAP Path Prefix. I'm using Dovecot 1.0_rc15 on Gentoo, and Mail.app from OS X 10.4.8, Thunderbird 1.5.0.9. With the old courier setup, in Mail.app I would see a top level Inbox folder, with an inbox icon'd folder underneath that representing the IMAP account. That IMAP account subfolder would be the inbox of that account. Under that, I'd see all the subfolders for that account. Something like: Inbox Account1 Folder1 Folder2 ... Account2 FolderA Outbox Drafts Sent Junk SmartFolder1 SmartFolder2 Note that a straight copy from the courier Maildir leaves me with directories like ~/Maildir/.Folder1 and ~/Maildir/.Folder2 -- IOW, they do not have .INBOX. prefix. I tried adding a "namespace private" section, with separator, prefix, and inbox values as specified in the docs. This gives me the same layout in the Mail.app u/i as with Courier, but there's a big problem: none of the folders under Account1 have any contents. The folders are there, and in the right location, but they have zero messages (even though they certainly have messages in the filesystem). Nothing in the Dovecot log file indicates any problem. But if I hover over say Folder1 in the Mail.app u/i, I see a popup message like: Mail was unable to open this mailbox on the server "imap.example.com". The server error encountered was: Unknown namespace Moving over to Thunderbird though, I see exactly what I want to see. Top level expandable is the account, with Inbox under that, which expands to all my folders. Of course Thunderbird supports subscriptions, which Mail.app does not, so I only see the folders I've subscribed to. Clearly, there's some weird interaction between Mail.app and Dovecot. Next, I tried removing the 'prefix' value from the "namespace private" section, and restarted Dovecot. Now the Mail.app u/i is different, but all the folders have their contents back! The u/i now shows: Inbox Account1 Account2 FolderA Outbox Drafts Sent Junk SmartFolder1 SmartFolder2 Account1 Folder1 Folder2 IOW, all of account1's folders live under a separate expandable section below the top level Inbox expandable (that section has a little world icon instead of the little inbox icon). Account1's inbox lives in a different section from its folders, but it has no subfolders. Looking back at Thunderbird, I notice that all the subscribed folders are now at the same level as the Inbox, just under the account name. I.e. Account1 Inbox Trash Folder1 Folder2 ... I suppose I can live with the Mail.app behavior sans the prefix setting in the namespace section, but it's not ideal. I'd really like to know why Mail.app has a problem with this! Why are the folders there but the contents empty? Is there any way to increase the logging that Dovecot does to understand what the Mail.app client is sending and why Dovecot is sending back that error? Any help would be greatly appreciated! - -Barry P.S. I wasn't able to use courier2dovecot.sh from the wiki (I think others had problems with running it on Linux as well, probably due to the different rename(1) syntax). The courier2dovecot.py file was no longer available, so I wrote my own. I can make that available to folks if there's any interest. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRZC8sXEjvBPtnXfVAQK90gQAjFhEH+vIPh7pnY4MuOTU8ChWfJ57ppIQ g0HvHidiD5nOfd8pfpsfacdD1nC40cRlpnJkR6vcahvqQsLzSUzUMwVlUqP2IDSE jGvZGpGSBpjTHV/ktWbyJhPo9+ehVxiq+qEfbDgfw9iqBtulOXe4M25iUKO8tsuA n2bCHHoUXuk= =hxad -----END PGP SIGNATURE-----

I need some help. I have compiled dovecot (1.0-rc15) with --with-mysql option, when I execute the binary with --build-options I get this: Build options: ioloop=poll notify=dnotify ipv6 openssl SQL drivers: Passdb: checkpassword passwd passwd-file shadow Userdb: checkpassword passwd prefetch passwd-file static In this case, when I execute dovecot I get this error: dovecot: Jan 03 03:48:47 Error: auth(default): Unknown userdb driver 'sql' (typo, or Dovecot was built without support for it?

[Dovecot] Dovecot 1.0-rc15 on Solaris 10
by Steven F Siirila 02 Jan '07

02 Jan '07

We are running Dovecot 1.0-rc15 on Solaris 10 and are starting to ramp up our user count and ran into a file descriptor limit: Jan 1 19:38:54 <hostname> dovecot: IMAP(username): Newly created index file is corrupted: /home/username/.imap/foldername/dovecot.index.tmp Jan 1 19:38:54 <hostname> dovecot: IMAP(username): file mail-index.c: line 1806 (mail_index_move_to_memory): assertion failed: (index->fd == -1) Jan 1 19:38:54 <hostname> dovecot: pipe() failed: Too many open files Jan 1 19:38:54 <hostname> dovecot: Temporary failure in creating login processes, slowing down for now We got around this by calling "ulimit -n 512" and restarting Dovecot. This got us further (upwards of 300 concurrent users), but we are now running into what appears to be a full listen queue (connections are not rejected, but rather slow in being established). What I would like to know is if anyone else out there runs with large numbers of concurrent IMAP sessions via Dovecot and has run into problems. If so, did you have to up your fd limit w/ulimit? Any other issues? -- Steven F.

[Dovecot] dovecot/vpopmail lastauth
by Rick Romero 02 Jan '07

02 Jan '07

Hi All, I have dovecot working wonderfully on a qmail/vpopmail, but I've noticed my 'lastauth' is never filled in.. If I use vpopmail's pop, and auth to that, then 'lastauth' is updated. It just seems weird that if dovecot is using the vpopmail lib, that lastauth wouldn't be updated. Has anyone else run into this? Thanks Rick

[Dovecot] Dovecot SASL vs. Micro$oft Outlook and Outlook Express
by Tom Kovar 02 Jan '07

02 Jan '07

Hi, I have just started using Dovecot (1.0.10) SASL behind my Postfix (2.3.3). Everything works fine, as long as I send the SMTP AUTH command manually. When using M$ Outlook (2000 and 2003) and Outlook Express 6, authentification always fails. Turning on the Dovecot auth debug on reveals the reason: Dovecot SASL expects, in accordance with the standards, the following format of the SMTP AUTH command (using the PLAIN auth mechanism): AUTH PLAIN base64_encode("username\0username\0password") whereas the M$ clients send as the second argument only base64_encode("username\0password"), which naturally leads to authentification failure. Postfix apparently does not play any role in this game, as it simply passes the received command arguments to dovecot. Before I start hacking the source myself, I just wanted to ask if somebody has a patch for this M$ shortcoming - as the damned M$ clients are very much spread, I would assume this should be the case... Thanx, --- Tom

[Dovecot] almost there with procmail and dovecot
by M. Fioretti 30 Dec '06

Hello, I am running dovecot-1.0-0_34 on Centos 4.4 In dovecot.conf I have: default_mail_env = maildir:/var/spool/mail/vhosts/%n/%d the content of that folder is: drwxrwxr-x 3 vmail vmail 4096 Dec 30 05:23 .. drwx------ 5 vmail vmail 4096 Sep 12 13:55 .Drafts drwx------ 5 vmail vmail 4096 Dec 29 18:26 .Sent drwx------ 5 vmail vmail 4096 Dec 30 03:37 .Trash drwx------ 5 vmail vmail 4096 Dec 30 05:23 INBOX drwx------ 5 vmail vmail 4096 Dec 30 05:10 INBOX.work drwx------ 5 vmail vmail 4096 Dec 30 05:10 INBOX.family drwx------ 2 vmail vmail 8192 Dec 30 03:32 cur -rw------- 1 vmail vmail 681 Dec 30 02:38 dovecot-uidlist -rw------- 1 vmail vmail 144 Dec 30 03:32 dovecot.index -rw------- 1 vmail vmail 21504 Dec 30 03:32 dovecot.index.cache -rw------- 1 vmail vmail 110300 Dec 30 03:32 dovecot.index.log drwx------ 2 vmail vmail 4096 Dec 30 03:25 new -rw-r--r-- 1 root root 18 Dec 30 05:21 subscriptions drwx------ 2 vmail vmail 4096 Dec 30 02:34 tmp and the subscription file contains: Sent Trash Drafts For reasons not really relevant here I need to use procmail as MDA: all the INBOX* Maildir folders are created by procmail with recipes like this: MAILDIR=same as in dovecot default_mail_env :0: * ^From: dad(a)his.isp.com INBOX.family #everything else goes to: :0 * w INBOX/ The problem right now is that procmail delivers all messages correctly but the folders are invisible to squirrelmail. From its interface I can only see Sent, Trash and Drafts. Is this a folder naming problem, a configuration issue or what? How must I name those inboxes and/or reconfigure dovecot to have those folders accessible in squirrelmail? TIA, Marco

[Dovecot] Correct naming scheme for dovecot / squirrelmail subfolders?
by M. Fioretti 28 Dec '06

28 Dec '06

Hello, I am running dovecot 1.0-0_34.rc15 and squirrelmail 1.4.8-2 on a Centos 4 server. Right now all messages are delivered to maildir /var/mail/vhosts/virtual_mail_root/, which has its cur, tmp, new subdirectories. I need to (re) configure postfix, dovecot and squirrelmail so that email is filtered and dovecot serves different boxes to squirrelmail, that is when I log in in squirrelmail I see: Inbox work (5) friends (6) lists (35) Sent Trash Spam that is every subfolder listed under Inbox with the number of unread messages. Now, I do know how to filter incoming email in different folders with postfix. The part still missing, in spite of several online searches, is the correct _naming_ and nesting of all the new mailboxes. In other words, if now everything goes into /var/mail/vhosts/virtual_mail_root/ : 1) what is the currect _name_ to give to the future "work" inbox ?? /var/mail/vhosts/virtual_mail_root/work/ /var/mail/vhosts/virtual_mail_root/INBOX.work/ what else? 2) which parameters must be changed and how in dovecot and/or squirrelmail (or any IMAP client in my home PC) so that folders are recognized and displayed as I wish?

[Dovecot] Dovecot + Outlook express + permission denied
by Nagy László 28 Dec '06

28 Dec '06

Hello, I have an account (called awesome) that does not have access to some public shared folders. I can use this account from Mozilla Thunderbird, but I cannot use it from Outlook. I opened /var/log/maillog. When I try to list all folders, I get this in the log: Dec 28 09:57:38 designaproduct dovecot: IMAP(awesome): opendir(/var/mail/public) failed: Permission denied However, outlook displays three folders: Inbox, Public and Trash. It says "One or more problems occured downloading your list of folder from your account." That is fine, except that not all folders are listed. (There are others: "Contact", "Calendar" and "ShopzeusArchive".) Then I subscribe to "Inbox" and "Trash". I DO NOT subscribe to "Public", because the account has no access to "Public". Then I click on "Inbox" (inside outlook) and I get this very long text: Dec 28 09:57:54 designaproduct dovecot: imap-login: Login: user=<awesome>, method=PLAIN, rip=62.112.202.90, lip=195.228.74.135, TLS Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Effective uid=1029, gid=1003 Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Namespace: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=yes, subscriptions=no Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): mbox: data=/home/awesome/:INBOX=/var/mail/awesome Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): mbox: root=/home/awesome, index=/home/awesome, inbox=/var/mail/awesome Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Namespace: type=private, prefix=, sep=/, inbox=no, hidden=no, subscriptions=no Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: data=/home/awesome/Maildir Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: root=/home/awesome/Maildir, index=/home/awesome/Maildir, control=, inbox= Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Namespace: type=public, prefix=Public/, sep=/, inbox=no, hidden=no, subscriptions=no Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: data=/var/mail/public:CONTROL=/home/awesome/Maildir/public/control Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: root=/var/mail/public, index=/var/mail/public, control=/home/awesome/Maildir/public/control, inbox= Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): lstat(/var/mail/public/cur) failed: Permission denied Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Sending log messages too fast, throttling..

Why outlook wants to open these folders? I only clicked on "Inbox", it should only open "Inbox", am I right? Outlook says "Could not select 'Inbox' on the IMAP server. You might try refreshing your folders list to synchronize with the IMAP server." But this is a lie. It tried to open many other folders, not just "INBOX". I think that my dovecot configuration is okay. I have different public and private folders. Some users can access all of them, others cannot. Using different groups of users, I can distribute permissions without problems. But I cannot make dovecot "hide" shared folders. Nor can I force all of my users to use Thunderbird. So how can I make outlook working? Thanks, Laszlo
