[Dovecot] dovecot produces messages dupes after nfs problems
by Patrick Westenberg 25 Jan '14

25 Jan '14

Hi everyone, some days ago I had trouble with my NFS-Server (high delays) which caused dovecot lmtp to deliver the same message several times (up to 10x). I recognized some old/unused .nfsXXXX files in the maildirs which seemed to be index files. I deleted them and everything was fine again. However, there are still 2-3 mailboxen where mails (old and new ones) are delivered multiple times. All duplicates have no "received from" headers. Seperate lmtp log shows only one delivery. Any hint or advice what might be wrong?

[Dovecot] Architecture for large Dovecot cluster
by Murray Trainer 25 Jan '14

25 Jan '14

Hi All, I am trying to determine whether a mail server cluster based on Dovecot will be capable of supporting 500,000+ mailboxes with about 50,000 IMAP and 5000 active POP3 connections. I have looked at the Dovecot clustering suggestions here: http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html and some other Dovecot mailing list threads but I am not sure how many users such a setup will handle. I have a concern about the I/O performance of NFS in the suggested architecture above. One possible option available to us is to split up the mailboxes over multiple clusters with subsets of domains. Is there anyone out there currently running this many users on a Dovecot based mail cluster? Some suggestions or advice on the best way to go would be greatly appreciated. Thanks Murray

hi, i tried to setup my configuration to use the SETQUOTA command but the only thing i got is: 3 setquota "User quota" (storage 12345) 3 OK Setquota completed. but nothing is changed in database. i modified the password_query and the user_query to return the admin and userdb_admin field, both set to y. all other changes that are done are like in the wiki http://wiki2.dovecot.org/Quota/Configuration enabling debug doesn't show anything in debug.log

[Dovecot] Dovecot imap-postlogin failed
by Sayajin 24 Jan '14

24 Jan '14

*** This is 2 posts combined into one which I had asked on linuxquestions.org and never got an answer *** Hi, In short I am trying to run a bash script which will then update a mysql database with the last login date/time & last IP for each mailbox. I have searched google dead but still cant figure out what im doing wrong or if there is some issue with the centos 6 rpm's for dovecot. -- - 1st i had the default dovecot in the centos 6 repo's which is version: 2.0.9 - I read that there was an issue with the script-login binary which was fixed in version 2.0.14, so i updated dovecot to version 2.2.7. - This sadly did not fix my issue with the bash script excecuting. In my /etc/dovecot/conf.d/10-master.conf i have the following service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script-login /var/www/lighttpd/mail-admin/scripts/lastLogin.sh } But when i try login i still get the same error as with the previous version: - Nov 27 14:44:36 dovecot: imap(MaIlBoX(a)DoMaIn.co.za): Error: net_connect_unix(/var/run/dovecot/imap-postlogin) failed: No such file or directory - One thing i did notice on the one site was that someone had a ls of their /var/run/dovecot directory, and in there was a binary called imap-postlogin. - But i dont have that binary anywhere on my server, with the old or new version of dovecot. Please any help would be appreciated. ===================================================== ===================================================== Ok well i tried a few other things and got it working a bit more.

[Dovecot] Writing an FTS plugin
by John Morrissey 23 Jan '14

23 Jan '14

Hi, I'm having some trouble writing an FTS plugin that uses notmuch (http://notmuchmail.org/) as the backend. As a proof of concept, I'm adding a hardcoded UID to the search results in the plugin's lookup handler: seq_range_array_add(&result->definite_uids, 1, 42); but this UID is never returned by IMAP SEARCH commands. I know the plugin is being used, since I'm also syslogging immediately before the call to seq_range_array_add(). Interestingly, SEARCH commands return correct results (based on the mailbox content and the search terms specified), but I'm not sure where those results are coming from. The notmuch plugin is the only configured FTS plugin: mail_plugins = $mail_plugins fts fts_notmuch plugin { fts = notmuch } What might I be doing wrong? Additionally, notmuch returns message filenames, which I'll need to translate to UIDs. I've seen maildir_uidlist_get_uid(), but I'm not sure where to get the struct maildir_uidlist arg it needs. notmuch only supports the Maildir format, so using a maildir_* function seems a reasonably safe assumption, but is there a better way? john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[Dovecot] Problem with LDA. When vacation auto-reply sent, the field from=<>.
by Dmitry 23 Jan '14

23 Jan '14

Hi, My problem is that when vacation auto-reply sent the field from=<> Because of this does not work "sender_dependent_relayhost_maps" in postfix. My scheme is: There are several postfix on different machines 1.1.1.1 - domain1 2.2.2.2 - domain2 3.3.3.3 - domain3 All they send messages to one server virtual_transport = lmtp:10.10.10.10:24 where mail is stored. In 10.10.10.10 installed dovecot 2.2.9, dovecot-pigeonhole 0.4.2 and another posfix In postfix inet_interfaces = 10.10.10.10 sender_dependent_relayhost_maps = hash:$config_directory/relayhost_maps relayhost_maps @domain1 [1.1.1.1] @domain2 [2.2.2.2] @domain3 [3.3.3.3] Sieve script make from Roundcube require ["vacation"]; # rule:[autoreply] if true { vacation :days 1 :subject "Test." "Test."; } (if add [":from" string] nothing changes) The letter comes, script fulfills, vacation auto-reply sent. But either /usr/sbin/sendmail -i -f <> -- user@senddomain or, if write in 15-lda.conf submission_host = 10.10.10.10:25 postfix log Jan 1 00:00:00 mail pf-OUT/cleanup[6098]: 4CD104A8A4: message-id=<dovecot-sieve-1390316174-295666-0@mail> Jan 1 00:00:00 mail pf-OUT/qmgr[5950]: 4CD104A8A4: from=<>, size=693, nrcpt=1 (queue active) How to make dovecot and dovecot-pigeonhole write in field MAIL FROM:?

[Dovecot] IDLE dropping EXISTS events on mass message arrival
by Eric Wong 22 Jan '14

22 Jan '14

Hi, I'm not sure if this is some throttling/DoS protection or a bug. I didn't see notice anything like it mentioned looking at the NEWS file from hg, this is on 2.1.7 on Debian stable. I have a client doing IDLE on INBOX.vomiteer. When individual messages arrive with some time interval in between them, I get EXISTS events for each message as expected. However, when I store a bunch of messages at once (via tag + mass copy in mutt on a fast-ish connection), I get a few EXISTS events (sometimes one, sometimes two) even though I copied a lot of new messages over. I expected to get an EXISTS event for each message which arrived, but perhaps there's some sort of DoS/throttling mechanism. strace -t -s4096 output of the dovecot process below: fd=13 is inotify, you'll see large read(13, ... indicating multiple filenames from inotify. However, only one EXISTS message got written to the socket. I've filtered out the gettimeofday syscalls for brevity. 07:30:02 epoll_wait(9, {}, 6, 3937) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 fstat64(10, {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 epoll_wait(9, {}, 6, 7865) = 0 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:14 write(11, "* OK Still here\r\n", 17) = 17 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:14 time(NULL) = 1390289414 07:30:14 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 22124) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\t\365\r\0000\0\0\0001390289417.M94623P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\n\365\r\0000\0\0\0001390289417.M94624P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\v\365\r\0000\0\0\0001390289417.M94625P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\f\365\r\0000\0\0\0001390289417.M94626P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\r\365\r\0000\0\0\0001390289417.M94627P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\16\365\r\0000\0\0\0001390289417.M94628P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\17\365\r\0000\0\0\0001390289417.M94629P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\20\365\r\0000\0\0\0001390289417.M94630P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\21\365\r\0000\0\0\0001390289417.M94631P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\22\365\r\0000\0\0\0001390289417.M94632P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\23\365\r\0000\0\0\0001390289417.M94633P14841.dcvr,S=3865,W=3968:2,S\0\0\2\0\0\0\200\0\0\0\24\365\r\0000\0\0\0001390289417.M94634P14841.dcvr,S=3865,W=3968:2,S\0\0", 32768) = 768 07:30:17 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 499) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\25\365\r\0000\0\0\0001390289417.M94635P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\26\365\r\0000\0\0\0001390289417.M94636P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\27\365\r\0000\0\0\0001390289417.M94637P14841.dcvr,S=1517,W=1552:2,S\0\0\2\0\0\0\200\0\0\0\30\365\r\0000\0\0\0001390289417.M94638P14841.dcvr,S=1517,W=1552:2,S\0\0", 32768) = 256 07:30:17 epoll_wait(9, {}, 6, 498) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 pread64(10, "\200\200\200\207@\0\0\20\0\0\0\0\0\0\0\0$\0\0\0\0\0\0\0\1\0\0\0\200\200\200\214\0\1\0\20\0\0$\0\337!\336R\344\231\2L\0\0\0\0\t\"\336R\t\"\336R\0\0\0\0\t\"\336R\0\0\0\0007\n\0\0\200\200\200\204 \0\0\20@\0\4\0\234e\0\0\200\200\200\242\2\0\0\20\317\0\0\0\10\0\0\0\320\0\0\0\10\0\0\0\321\0\0\0\10\0\0\0\322\0\0\0\10\0\0\0\323\0\0\0\10\0\0\0\324\0\0\0\10\0\0\0\325\0\0\0\10\0\0\0\326\0\0\0\10\0\0\0\327\0\0\0\10\0\0\0\330\0\0\0\10\0\0\0\331\0\0\0\10\0\0\0\332\0\0\0\10\0\0\0\333\0\0\0\10\0\0\0\334\0\0\0\10\0\0\0\335\0\0\0\10\0\0\0\336\0\0\0\10\0\0\0\200\200\200\207@\0\0\20\1\0\0\0\0\260\2L\0\0\0\0\4\0\4\0\1\0\0\0\200\200\200\242\0\2\0\20\317\0\0\0\250\275\0\0\320\0\0\0\234\277\0\0\321\0\0\0|\301\0\0\322\0\0\0|\304\0\0\323\0\0\0\200\307\0\0\324\0\0\0|\312\0\0\325\0\0\0h\315\0\0\326\0\0\0\\\320\0\0\327\0\0\0\224\323\0\0\330\0\0\0\210\325\0\0\331\0\0\0h\327\0\0\332\0\0\0h\332\0\0\333\0\0\0l\335\0\0\334\0\0\0h\340\0\0\335\0\0\0T\343\0\0\336\0\0\0H\346\0\0\200\200\200\204 \0\0\0200\0\4\0\337\0\0\0", 8192, 25920) = 408 07:30:17 pread64(10, "", 8192, 26328) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 time(NULL) = 1390289417 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:17 write(11, "* 32 EXISTS\r\n", 13) = 13 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:17 epoll_wait(9, <unfinished ...> (Nothing happened after this) #

This is probably easy but how would a set a secret static master password so that if I typed it in for any login it would be happy? I can't use the * separator method in this case because it screws up squirrelmail.

[Dovecot] Failure in doveconf
by Andrew Ray 21 Jan '14

21 Jan '14

I ran into a problem while configuring dovecot. Quickly reading the paragraph below, I saw "yes" as one of the options, and put that into the config, as below: # In case of password mismatches, log the attempted password. Valid values are # no, plain and sha1. sha1 can be useful for detecting brute force password # attempts vs. user simply trying the same password over and over again. # You can also truncate the value to n chars by appending ":n" (e.g. sha1:6). auth_verbose_passwords = yes The result from doveconf -n was: doveconf: Error: x�η doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: 0pη (where the error message was always a changing, apparently random set of characters.) So I managed, by going back through the config file and commenting out options, to find this was the problem and then finally read what are the acceptable values. Any other place that I have tried to give a non acceptable value I get a reasonable error message with line number and problem. Well, now I fixed my original problem, but something needs to be adjusted in the error handling code.

[Dovecot] forwarded message is broken in 2.2.10 with pigeonhole-0.4.2
by Burckhard Schmidt 21 Jan '14

21 Jan '14

Hi, forwarding a message with sieve like redirect:copy "me(a)other.domain"; was working without any problem until dovecot-2.1.17, dovecots lmtp and dovecot-2.1-pigeonhole-0.3.5.

[Dovecot] Dovecot doesn't seem to report all subfolders to Thunderbird
by dovecot＠voidptr.de 21 Jan '14

21 Jan '14

Hi, I've recently migrated my emails from a Yahoo account to my own mailserver on a VPS. Ever since then, Thunderbird seems to have issues with the mailbox's directory structure: When I start Thunderbird, it immediately deletes the local copies of all 3rd-level folders (i.e. subfolders of a subfolder of a folder in the mailbox root). Since that didn't happen with the Yahoo account, I assume it's some kind of error or misconfiguration of Dovecot. Here's an example of the mailbox structure: voidptr.de '-> University '-> IEEE '-> Conference "University" and "IEEE" work without problems, but "Conference" gets deleted locally every time I start Thunderbird. When I collapse and re-expand "University" in the folder panel, all subfolders (including "Conference") reappear, but Thunderbird has to re-download the contents of "Conference", since it deleted the local copies earlier. It looks as if Dovecot only reported the topmost two folder levels when Thunderbird requests a folder list... Is there any way I can change that behavior? Nils $ doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab078.22 x86_64 Debian 7.3 auth_verbose = yes mail_location = maildir:~/Maildir:LAYOUT=fs namespace { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = subscriptions = yes } passdb { args = scheme=SHA512-CRYPT username_format=%n /etc/dovecot/users driver = passwd-file } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { inet_listener imaps { port = 0 } } ssl = required ssl_cert = </etc/ssl/certs/own/voidptr.de.pem ssl_key = </etc/ssl/certs/own/voidptr.de.key userdb { args = username_format=%n /etc/dovecot/users default_fields = home=/home/%n driver = passwd-file }

[Dovecot] A variable for the unix user or home path would be useful in some cases
by interfaSys sàrl 20 Jan '14

20 Jan '14

Hello, In our hosting environment, we let users share mailboxes across all their domains and think it's best if the shared mailbox listing (in a file) stays in their unix home path. That would be: /home/USER/imap/shared-mailboxes.db Unfortunately, it seems there is no way to generate that path using a variable. Something like this would be convenient: acl_shared_dict = file:%v/imap/shared-mailboxes.db Instead, we have to use something like this: acl_shared_dict = file:~/../../../shared-mailboxes.db which only works for virtual users. Did somebody solve this another way? Could we have the unix user or home path as a variable? Or could we have a modifier giving us the path or the unix user based on the unix UID? Cheers, Olivier

Re: [Dovecot] imap abort after upgrade from 2.2.4 to 2.2.7
by morrison 20 Jan '14

20 Jan '14

When I did upgrade, 2.2.7 was the latest release. When I ran into the problem, I checked back and found 2.2.8 and 2.2.9 were released shortly one after another. It seemed these releases were sort of buggy. I would like to know if what I described in my previous email was an known issue and was addressed before upgrade to 2.2.10. We are using dovecot as our internal mail service. So stable is most important to us. Regards,

[Dovecot] auth_default_realm, pam_krb5, gssapi
by Sergey Urushkin 20 Jan '14

20 Jan '14

Hi, Just writing here my note about auth_default_realm, pam_krb5 and gssapi. It seems that 'pam' passdb and 'gssapi' auth_mechanism doesn't honor 'auth_default_realm' setting, at least in several setups I deal with. Here is a part of the config: passdb { args = max_requests=100 cache_key=%u%r dovecot driver = pam } auth_default_realm = REALM.COM auth_mechanisms = plain login apop gssapi auth_username_format = %Uu The problem is that pam_krb5 strips default realm from username (by default), even if auth_default_realm is specified and even if user logs in as 'user1(a)realm.com' (with domain part). A part of auth.log: mail auth: pam_krb5(dovecot:auth): user USER1 authenticated as USER1(a)REALM.COM The same for GSSAPI auth, if specified authorization name doesn't contain domain part. A part of mail.log: mail dovecot: imap-login: Login: user=<USER1>, method=GSSAPI, rip=172.16.0.1, lip=192.168.1.1, mpid=5828, TLS, session=<bpzvRmDwPACsFwCX> For several reasons I do need username inside dovecot to contain domain part. So, I found a solution to this problem - modifying /etc/krb5.conf this way: [libdefaults] default_realm = REALM.COM [realms] REALM.COM = { auth_to_local = RULE:[1:$1@$0] } This will add realm part to the local username despite using default realm. Maybe it's better to put this example to the wiki? Tested with ubuntu 12.04 and dovecot 2.2.10, mit kerberos 1.10, amd64. Taking the opportunity, I'd like to ask, is there a way to make usernames case insensitive while using GSSAPI. The case: klist shows: Principal: user1(a)REALM.COM username in thunderbird 'uSer1(a)REALM.COM'. Dovecot gives me this message (I use auth_username_format=%Uu for pam_krb5 to be able to login with lowercase realm): dovecot: auth: gssapi(USER1(a)REALM.COM,172.16.0.1,<IIgwMGbw3ACsFgA4>): User not authorized to log in as USER1(a)REALM.COM As I know kerberos usernames are case insensitive (user part), at least kinit and windows against AD works that way. Seems that k5credentials passdb extra field will not help here too. Does anyone have an idea? Thanks. -- Best regards, Sergey Urushkin

[Dovecot] Shared Folters with LDA/Sieve
by Dieter Knopf 19 Jan '14

19 Jan '14

Hello, i'm searching for a way to use Shared mailboxes with Sieve Filtering. I need global email addresses like: info(a)foo.tld contact(a)foo.tld help(a)foo.tld Every address with own Sieve-rules for filtering and sorting of incoming mails. Now every user needs access to this folders, but how? How should i create the "global" addresses? I already found http://wiki2.dovecot.org/SharedMailboxes/Public , but that's just a public namespace. Is there any FAQ available for this? Thank you very much Dieter

[Dovecot] Sizing MTA servers
by Murray Trainer 18 Jan '14

18 Jan '14

Hi All, This is probably a bit off-topic but does anyone have any idea about sizing MTA servers. We have about 200,000 emails/hr incoming and outgoing. I am intending using Exim and Spamassassin on each MTA. How many servers using recent hardware would I need to cope with this mail throughput? What is more important on the servers, CPU or RAM? Should I have mail going both directions on each server or dedicate a pair each for incoming and outgoing mail> Thanks for any feedback. Murray

[Dovecot] doveconf base_dir
by Andreas Schulze 18 Jan '14

18 Jan '14

Hello, today I run the command "doveadm auth cache flush" for the first time. # doveadm auth cache flush doveadm(root): Error: userdb lookup: connect(/var/run/dovecotauth-master) failed: No such file or directory 0 cache entries flushed # base_dir was the only item contain 'run' and it did not end with a / So I tried to set base_dir to /var/run/dovecot/ and could now rerun "doveadm auth cache flush" without problems. I compile dovecot from source and found --with-rundir=/var/run/dovecot as an option to configure. I changed to /var/run/dovecot/, recompile and removed the base_dir setting in dovecot.conf again. Now "doveadm auth cache flush" work out of the box. doveconf -d base_dir is var/run/dovecot/. Finaly I compiled dovecot with --localstatedir=/var and removed --with-rundir from configure. The resulting package had again base_dir = /var/run/dovecot so "doveadm auth cache flush" don't work. looks like somewhere the missing / should be added in case base_dir has no trailing / without special configuration.

[Dovecot] imap abort after upgrade from 2.2.4 to 2.2.7

Hi, I used to use dovecot 2.2.4. I saw lots of warnings saying 'Extension header update points outside header size'. I upgraded to dovecot 2.2.7, based on the discussion in mail list. Now, I see lots of imap aborts around: src/lib-index/mail-index-transaction-export.c:203: i_assert(u32.offset + u32.size <= ext_hdr_size); I also noticed, in some mailbox, imap process kept abort until all index files in the mailbox were manually deleted. Did someone run into the same problem and any solution to this? Thanks,

[Dovecot] Changing user specific configs one at a time using userdb text file to override defaults...
by Charles Marcus 17 Jan '14

17 Jan '14

Hi all, Ok, I'm now interested in testing converting users one at a time to mdbox+SIS, but want to make sure I understand how to do this. It appears the best way - for smaller installations at least - is to just use a simple text file userdb to override the defaults, then once all of the users have been converted, change the defaults and remove the userdb txt file overrides. So, would love to hear details from others who have done something like this. Thx! -- Best regards, Charles

[Dovecot] Getting more out of the %w variable.
by Julian PG 17 Jan '14

17 Jan '14

Hello Dovecot community, I have a backend database application that handles all system wide user authentication (from web to mail and more). Passwords are not stored in plain text. So I would like to support more than PLAIN. Perhaps at least CRAM-MD5 or DIGEST-MD5 for example. Even though connections over TLS are encouraged (and even enforced). Some MUA and users still think its a better idea than PLAIN (even sent over an encrypted session). I have a vague memory of getting some warnings with thunderbird in regards to the use of PLAIN. Of course the %w variable would have to include the challenge as well as the response. Or perhaps even a seperate variable for the challenge? Or course at the moment the %w variable is an empty string for anything other than PLAIN. This would make some users and MUAs happy (even though pointless over TLS - I agree). Your thoughts would be appreciated. Regards, Julian. -- Not time for sigs!

[Dovecot] Received: header showing 127.0.0.1 after switch to dovecot LDA?
by Charles Marcus 16 Jan '14

16 Jan '14

Hi all, I'm guessing this is correct behavior, but wanted to make sure... I noticed that for locally delivered messages (between 2 local users inside our domain, so they never leave the server), the first Received: header line content changed after I switched to the dovecot LDA. Before, using postfix/virtual for delivery, the header looked like this: Received: from [192.168.1.25] (client.example.com [192.168.1.25]) by smtp.example.com (Postfix) with ESMTPSA id 67E33A20542; Wed, 6 Jun 2012 10:55:55 -0400 (EDT) But now it looks like this: Received: from [127.0.0.1] (client.example.com.com [192.168.1.14]) by smtp.example.com (Postfix) with ESMTPSA id 4EEF7802AF325 for <me(a)example.com>; Wed, 15 Jan 2014 18:29:17 -0500 (EST) so, 2 questions... 1. Why does it show 127.0.0.1 instead of the client IP, and 2. Why did postfix/virtual include the "for <me(a)example.com>;" but the dovecot LDA doesn't? Thanks, -- Best regards, Charles

[Dovecot] EAGAIN in dict proxy
by Richard Platel 15 Jan '14

15 Jan '14

Hello, We’re using a custom program to manage quotas talking to dovecot via the dovecot dict proxy protocol over a unix socket: plugin { quota = dict:User quota::proxy:/var/run/auth_proxy_dovecot/quotasocket:quota } Dovecot gets slammed with quota requests periodically, seemingly because Thunderbird thought it would be a good idea to hardcode having a quota check at 45 seconds past the minute, and thus every Thunderbird client makes several GETQUOTAROOT requests simultaneously. This causes dovecot to make many client connections to the quota proxy, and many of them fail with EAGAIN. In the log we see: Jan 15 16:52:46 imap25 dovecot: imap(rplatel(a)tucows.com): Error: net_connect_unix(/var/run/auth_proxy_dovecot/quotasocket) failed: Resource temporarily unavailable And the client gets: * QUOTAROOT Spam "User quota"[0d][0a] * QUOTA "User quota" ()[0d][0a] * BAD Internal quota calculation error[0d][0a] 19 OK Getquotaroot completed.[0d][0a] Thunderbird transparently disconnects and reconnects at this point but obviously this is not ideal. Writing some toy programs, I found that even making a forked server with several processes doing nothing but accept()ing on the listening socket, with a high number for the listen queue, it’s easy to overwhelm it with simultaneous clients who then get EAGAIN. If the clients do indeed immediately try again, they are successful. (An INET listening socket does not seem to have this problem, incidentally) All of this is a long-winded way of saying that I believe in lib-dict/dict-client.c:client_dict_connect() the call to net_connect_unix should be a call to net_connect_unix_with_retries() with a small timeout. It would also be useful for us if an INET socket could be used.

[Dovecot] int/ext mailserver
by Mr.Pine 15 Jan '14

15 Jan '14

I 'm using potfix-dovcote as an internal mail server(local.myco.com) and wan to run another potfix-dovcote as an external mail server (myco.com) on Internet.75% of my users should only work internally(no external mail) but the rest of users (25%)should be able to send mail to external network! These users have the same username on myco.com. I use smtp_generic_maps to map int username of these users to ext. one. For eg. All email send by test(a)local.myco.com map to test(a)myco.com. So anyone got these mails can reply them. I know that getmail is the tools that can get mails from users external mailbox and put them into int. mailbox. 1. I have a root access to ext mail server. But do not know my ext user password!. How can I use getmail to move ext mail to internal one?! 2. What is your idea about syncing users password in internal/external mail server?! I think its needed for getmail! 3. How can I restrict my internal users to send mail only internally!? I appreciated any help!! TNX

[Dovecot] restored mails
by Wojciech Giel 15 Jan '14

15 Jan '14

Hello, I am running dovecot 2.1 on debian wheezy . We are using maildir format. one of our uses deleted content of INBOX folder during xmass. he wants these messages back. I had these mail on tape.

[Dovecot] Why does dovecot require the {} password sheme even if there is a $ crypt scheme.
by da-dovecotlist-15＠abelonline.de 15 Jan '14

15 Jan '14

The wiki[1] says: If all the passwords are in same format, you can use default_pass_scheme to specify it. Otherwise each password needs to be prefixed with "{password-scheme}", for example "{plain}plaintext-password". Why doesn't dovecot recognize the crypt scheme identifier ($1$ for MD5-CRYPT, $6$ for SHA512-CRYPT etc.)? At the moment I have to have the following in my db for dovecot to work: {SHA512-CRYPT}$6$salt$passwordhash [1]http://wiki2.dovecot.org/AuthDatabase/SQL

[Dovecot] dsync mbox to maildir migration does not delete, deleted e-mails
by A M 15 Jan '14

15 Jan '14

Hello, I am planning to migrate all users from mbox to maildir. I am trying to do it with minimum downtime. (~100GB data) All users are currently using POP3. Dovecot version is 2.2.10 (latest). Command used is: dsync -u username mirror maildir:~/Maildir Process I plan is: (omitting steps related to sendmail / procmail) 1) keep dovecot running (with mail_location as mbox) 2) dsync for all users (this may take 3-4 hours or more) 3) (downtime starts) stop dovecot and sendmail (to stop new e-mails) 4) block pop3, imap ports on firewall (so users can not connect) 5) start dovecot (still with mbox) 6) dsync again to sync e-mails arrived between step 2 and 3 7) dsync again (just to make sure!) 8) (downtime ends) restart dovecot (with mail_location as maildir) Now, here is my problem. Lets say there is user joe, who has 50 NEW e-mails in mbox (INBOX). Step 2 perfectly syncs his 50 e-mails to 'new' folder of maildir. Now in the mean time, before step 3, he connected via POP3 and downloaded and deleted 50 e-mails. Now when we reach step 6 (re-sync), what I expected was dsync will detect that 50 e-mails are deleted and it will delete 50 e-mails from 'new' directory of maildir. But that is not happening. 50 e-mails are still there. I fear that these e-mails will be re-downloaded on his Outlook once I switch dovecot to maildir. This will happen for each and every user which will cause huge mess. So how to tell, dsync to delete non-existent e-mails which are no more there in mbox (INBOX)? Thanks in advance, Regards, A M

[Dovecot] Dovecot service not responding after about a week of uptime
by Matthieu 15 Jan '14

15 Jan '14

Hello, I am running a dovecot 2.1.13 server and lately it stops responding after about a week of uptime. Simply restarting the dovecot service solves the issue. I tried to look a bit in my maillog file but did not find anything obvious. During the time when the server is not responding I can still see imap-login entries from the connection attempt by my email client. Any help about how to diagnose the problem would be appreciated. Thanks, Matthieu

[Dovecot] Dovecot LMTP does not pass envelope recipient +detail to sieve
by Greg Rivers 14 Jan '14

14 Jan '14

I found this[1] thread that describes the same problem with dovecot-LDA, but the solution (add X-Original-To: header) has no effect with LMTP. My sendmail LMTP configuration: FEATURE(`local_lmtp',`[IPC]',`FILE /var/run/dovecot/lmtp') Sendmail's address test indicates that sendmail is providing user+detail to LMTP (see below). Except for this problem, dovecot, LMTP, and sieve are all working perfectly. Is there something I'm missing, or is this a bug?
