[Dovecot] dovecot-stable: NIL from in envelope request

16 Feb '05

Using the latest dovecot-stable (20050213) with pine, I get an empty "from" header in my e-mails. This doesn't happen with 1.0.59-test, nor did it happen with the first dovecot-stable (20050131).

[Dovecot] Messages keep getting resent.
by poohba＠blkpoohba.dyndns.org 16 Feb '05

16 Feb '05

I have IMAP and POP running and when I log in thru pop from my blackberry which is the only way it pulls all the new emails. When I log into my computer and check email via PINE i guess something is refreshed because very soon there after if not immediately all the emails in the INBOX are sent/pulled from my blackberry again. Why is this happening?

[Dovecot] Speed up large maildirs
by Leen Besselink 16 Feb '05

16 Feb '05

Hi, I'm very fond of maildirs, they are simple, I like that. But I've never really understood the significance of maildir/new/. The only use I can see is that (for example in the case of dovecot), you'd move a message from new to cur and then update the index-file, that's it. So to make put it more direct, you'd know when and with what to update the index-file, based on where the file resides. I've never been bothered by them, until I found that that is the last hurdle for fast access to a large (and receiving a lot of mail) Maildir. I've been thinking long and hard about what to do to make them work even better. My idea at this point is the following, use maildir/new as little as possible, just use it for what it was intented and spread the time of updates. If someone would make a wrapper-program around the delivery-program (like qmail-local, vpopmaildeliver, procmail or local and virtual from postfix) and the delivery program would print to standard output the path+filename it saved a (or more) message(s) to, the wrapper would be able to send an update-message to a dovecot-daemon. That mean, updates are small, and opening a large maildir would be sped up. How does that sound ? I hope this is a helpfull suggestion. _____________________________________ New things are always on the horizon.

[Dovecot] Why am I getting more imap folders?
by poohba＠blkpoohba.dyndns.org 16 Feb '05

16 Feb '05

At one point I was just using what was under ~/mail now I have: ~/mail ~/mail/fedora ~/mail/trash ~/mail/mplayer ~/mail/yahoo ~/mail/Scott ~/mail/.imap/fedora ~/mail/.imap/fedora/.imap.index ~/mail/.imap/fedora/.imap.index.tree ~/mail/.imap/trash ~/mail/.imap/trash/.imap.index ~/mail/.imap/mplayer ~/mail/.imap/mplayer/.imap.index ~/mail/.imap/yahoo ~/mail/.imap/yahoo/.imap.index ~/mail/.imap/yahoo/.imap.index.data ~/mail/.imap/yahoo/.imap.index.tree ~/mail/.imap/Scott ~/mail/.imap/Scott/.imap.index ~/mail/.imap/INBOX ~/mail/.imap/INBOX/.imap.index ~/mail/.imap/old_subscriptions/.imap.index ~/mail/.imap/old_subscriptions/.imap.index.data ~/mail/.imap/ffmpeg ~/mail/.imap/ffmpeg/.imap.index ~/mail/.imap/apache ~/mail/.imap/apache/.imap.index ~/mail/.imap/dovecot ~/mail/.imap/dovecot/.imap.index ~/mail/ffmpeg ~/mail/apache ~/mail/dovecot These are not all the files but just the most recently touched files. Can I not just have imap view and use the ~/mail files? Is this normal? Can I have it set up to use the maildir files that are already there? It used to work that way but I guess that is with the other imap server that came with fc1.

[Dovecot] changing user mail folders
by Jason M. Wilde 15 Feb '05

15 Feb '05

I have a working dovecot server with user mail in Maildir:~/Maildir What is the proper way to change the location of user mail to /var/mail/username to take advantage of a large /var drive space? Would you recommend adding the creation of new user directories in /var/mail to my Redhat "adduser" script to get the permissions correct? Or via some other method? Also, any idea how to make Postfix deliver mail to the the new user directories? Thank you for any help and for a great product. Jason

[Dovecot] Need 2 additional folders like INBOX for JUNK and INFECTED mails
by Mirko Schulze 15 Feb '05

15 Feb '05

Hi there, i need for JUNK & INFECTED mail two folders like INBOX. The folders must be fixed in naming, permissions and so on. I've adjusted some commands in the ./src/imap folder. But it's work not really fine: Creating a folder works, but deleting too. *smile* Moving a "special-name-folder" (f.e. from Trash) to its correct place, Dovecot says, that the folder is currently there. subsribing / unsubscribing doesn't work, too. ... ... ... I think that this is a "standard" problem for much people, who don't want, that the users will delete files through the imap protocol. Are there any solutions? Thanx Mirko

[Dovecot] 0.99.14 released
by Timo Sirainen 15 Feb '05

15 Feb '05

One more change since -rc3 (the last one in list). v0.99.14 2005-02-11 Timo Sirainen <tss(a)iki.fi> - Message address fields are now parsed differently, fixing some issues with spaces. Affects only clients which use FETCH ENVELOPE command. - Message MIME parser was somewhat broken with missing MIME boundaries - mbox: Don't allow X-UID headers in mails to override the UIDs we would otherwise set. Too large values can break some clients and cause other trouble. - passwd-file userdb wasn't working - PAM crashed with 64bit systems - non-SSL inetd startup wasn't working - If UID FETCH notices and skips an expunged message, don't return a NO reply. It's not needed and only makes clients give error messages.

Re: [Dovecot] Help, problems with permissions
by Simon Windsor 14 Feb '05

Hi Thank you for the reply. The documentation on the wiki/dovecot site clearly provides an example exim transport statements showing mail writes as dovecot/dovecot with permisions of 600. The mail system uses virtual users, and I have provided mail/group ids of 1001/1001. The current directory tree is /home - owned by root /home/dovecot - owned by root /home/dovecot/users - owned by root, 777 /home/dovecot/users/DOMAIN - owned by 1001:1001, 777 /home/dovecot/users/DOMAIN/USER - owned by 1001:1001, 777 /home/dovecot/users/DOMAIN/USER/cur - owned by dovecot:dovecot, 600 /home/dovecot/users/DOMAIN/USER/new - owned by dovecot:dovecot, 600 /home/dovecot/users/DOMAIN/USER/tmp - owned by dovecot:dovecot, 600 Can you confirm that all files should be owned by 1001/1001? What permissions should should exist on these directories/files?

[Dovecot] Problems with dovecot using Maildir on JFS.

Howdy, I have dovecot installed on CentOS (rhel3 clone), and I'm using Dag's dovecot package. I have postfix setup to deliver to Maildir, in /home. The /home volume was formatted with JFS. In this setup, both Outlook and Thunderbird would not show any new mail unless they were completely shutdown and restarted. I have moved /home to an ext3 formatted and all is well. Anyone have any insight on this? Thanks, jrw

[Dovecot] outstanding issues with 0.99.13
by sean finney 10 Feb '05

10 Feb '05

hi list, i'm in the process of testing dovecot before a hopeful switchover from uw-imap/qpopper to dovecot, primarily to get off of the uw-imap/mbox combo and moved to Maildir. i think we've worked out the logistics to avoid any service downtime, with only a short window of a few minutes per user for when we convert from mbox to maildir format. however, during testing a few issues have come up, some of which i've been able to work around, others which i haven't. for those that i have been able to work around, i'll include my solution so that fellow googlers may profit, and for those that i haven't i'd really appreciate your feedback. logistical problems: 1 - automagic detection and uw-imap inbox in ~/mbox. i'm not sure if this is a default characteristic or if it's specific to us, but our spool is in /var/mail/foo and inbox in ~/mbox. the automagic Maildir/mbox detection doesn't find the "mbox", and i can't tell it where it is because then it doesn't look for the Maildir. solution: i wrote a small patch to dovecot's autodetect code to help it find the location of our mailboxes. if anyone would like a copy of said patch i can send it off list. 2 - uw-imap's spool/inbox message moving. i read from the wiki that this isn't a feature currently being worked on. solution: deliver all mail to the same place. since we use procmail as our MDA, this isn't too hard of a problem. basically we redirect mail to the inbox and redeliver everything in the spool. 3 - supporting multi-homed services + ssl. for historical reasons we provide services from multiple hostnames (mail.foo, imap.foo, etc). with ssl, that means a different cert for each, otherwise some clients will break. solution: we're spawning off three seperate dovecot instances, each using a different config file. not the most graceful, but it works... application problems: 4 - dovecot imap + ms lookout 2002 + deleting messages. i'm not sure if this is an app or server side problem. basically, a user will delete a message, only to have it reappear in the mailbox a short time (few minutes) later. if i monitor the state of the mbox file, no changes are made to it until the user selects "empty trash", after which point they are expunged. looking at a protocol dump, i see the client setting the deleted flag on the message when they originally delete it. here's an excerpt: <snip> tg7i OK Idle completed. 6gzd UID STORE 30021 +FLAGS (\Deleted \Seen) * 51 FETCH (FLAGS (\Deleted \Seen \Recent) UID 30021) 6gzd OK Store completed. stpw IDLE <snip> i'm not too familiar with imap, but it looks like the server is caching the deletion request and then forgetting later forgetting about it? i have all the "client workarounds" enabled, fwiw. solution: ??? 5 - mac os x + eudora + deleting mail. a different problem alltogether. in eudora deleting a mail seems to immediately move it to the "trash" mailbox, so the above problem does not occur. what *does* happen is that if a user rapidly deletes messages one-by-one, an error message pops up about UID's not existing. i haven't gotten a full description of this problem, but here's an excerpt from what i think is the symptom: <snip> A00109 UID COPY 30002 Trash A00109 OK Copy completed. A00110 UID STORE 30002 +Flags.silent (\Deleted) A00110 OK Store completed. A00111 EXPUNGE * 31 EXPUNGE A00111 OK Expunge completed. <snip> and later: <snip> A00040 UID FETCH 30002 (UID BODYSTRUCTURE) A00040 NO Some of the requested messages no longer exist. A00041 UID FETCH 30002 RFC822.SIZE A00041 NO Some of the requested messages no longer exist. A00042 UID FETCH 30002 (BODY.PEEK[]) A00042 NO Some of the requested messages no longer exist. <snip> which i suppose is correct that it doesn't exist (since it was moved out of the inbox). however, eudora does not have this problem with uw-imap, and i'm wondering what might be causing it? solution: ??? okay, i think that's everything that i've ran into. we're still pushing ahead with this because we need to get the hell off of uw-imap/mbox, but i don't think we'll be able to stick with dovecot if these are unresolvable issues. in that case, we'll probably use dovecot with these minor nuisances while we transition, and then perhaps use courier in the long run. hopefully that won't have to be the case though :) if anyone has any experience specifically with "5" and "5", i'd really, really like to hear about it. in the meantime, i'll continue to test other things, and also see if the problem also persists when mail is stored in Maildir format. anyway, thanks for your time! sean

[Dovecot] Corrupted index file w/Procmail in FC2
by Edgardo Pezoa 09 Feb '05

09 Feb '05

Hello: We have a Fedora Core 2 (FC2) server with Dovecot and Procmail. Versions are: dovecot-0.99.13-4.FC2 procmail-3.22-13 We use "maildir" below home directory like: /users/operaciones/epezoa/maildir, where "epezoa" is my account. If I receive an e-mail, is stored at "new" folder. When I try to get e-mail from server, message is transfered from "new" folder to "cur" folder, but I can't see my e-mail and Dovecot generates a "Corrupted index file" in log file: Feb 8 14:02:34 dlp1 pop3(epezoa): Corrupted index file /users/operaciones/epezoa/maildir/.INBOX/.imap.index: index.next_uid (14836) > uid_rec.uid (14825) But, If I receive another e-mail (at "new" folder) and I try to get messages, I get both. My clients are Mozilla (with "pop3") and Squirrel (from another server with "imaps"). Both have same behavior, so I think client is not involved in this problem. MTA is Postfix, but all accounts works well, except who use Procmail. I read about locking in Procmail and Dovecot and I think locking may produce this problem, but I can't find what's wrong. I upgraded dovecot from dovecot-0.99.10-5 to try fix this. Thanks in advance, -- Edgardo Pezoa

Among other things I started working half-time at Movial (www.movial.fi) I had forgotten 8 hour work days at office could take so much time :) Anyway.. There has been a few changes since RC1 so I'll still make RC2 before the final. Changes since RC1: - passwd-file userdb wasn't working - PAM crashed with 64bit systems - non-SSL inetd startup wasn't working - upgraded setuid/setgid initialization code from 1.0-tests

[Dovecot] File isn't in mbox format - Couldn't open INBOX
by Girish Patangay 09 Feb '05

09 Feb '05

I cannot reproduce this error everytime, but it seems to happen when Outlook tries to delete the first message (the first message in the file, message on top) in the /var/mail/user file. I tried looking through the mailing list but came up blank. Is this a known problem? I can fix this problem by editing the file manually and fixing the file. If I delete the first 2 lines (in the example below) and make sure the Inbox file starts at "From ..." it works fine again. Here is the log: ---------------------------------------------- Feb 2 09:23:45 angel pop3-login: Login: sathyan [127.0.0.1] Feb 2 09:23:45 angel pop3(sathyan): File isn't in mbox format: /var/mail/sathyan Feb 2 09:23:45 angel pop3(sathyan): File isn't in mbox format: /var/mail/sathyan Feb 2 09:23:45 angel pop3(sathyan): Couldn't open INBOX: Internal error occured.

[Dovecot] TROUBLES WITH dovecot configuration
by Alexey S. Kuznetsov 09 Feb '05

09 Feb '05

Hello! I'm new in this list and new to dovecot, so I have some troubles with its configuration. I have an Linux OS installed and Postfix what supports virtual domains and places mail to: /var/spool/mail/vhosts/DOMAIN_NAME/ I've installed dovecot, configured it to use only pop3 proto. Configuration like this (most important lines from config) # cat /usr/local/dovecot/etc/dovecot.conf login_user = dovecot default_mail_env = mbox:/var/spool/mail/vhosts/%d/%n auth = default auth_mechanisms = plain auth_userdb = passwd-file /usr/local/dovecot/ps/pop.users auth_passdb = passwd-file /usr/local/dovecot/ps/pop.users auth_user = root cat /usr/local/dovecot/ps/pop.users testemail@mydomain.org:1a1dc91c907325c69271ddf0c944bc72[34]:1000:7266::/var/spool/mail/vhosts/mydomain.org/::: My system uid is 508, when I set it in pop.users file it works nice: accepts password, lists mail, everything. But when I want to create uniq. id for my domain: useradd -d /dev/null -s /bin/date -u 1000 mydomainorg telnet localhost 110 Trying 127.0.0.1... Connected to localhost.localdomain.

Refer to server log for more information. [2005-01-28 22:11:02] If I set uid 508 everything will be cool! I don't understand why it works like this? I logged in to my account and via sudo su - I became root user. Root has uid 0, and why it works with uid 508 I can't even imagine :( Please help me with this problem. Thanx! -- Sincerely, Alexey S.

[Dovecot] Corrupted index file
by Frank Hart 09 Feb '05

09 Feb '05

I've recently switched from Courier-imap to dovecot and I'm impressed with it's speed and reliability. However, my index file gets regularly corrupted: Feb 8 21:23:16 hive imap(hart): Corrupted index file /home/hart/Maildir/.INBOX/.imap.index: index.next_uid (129) > uid_rec.uid (128) dovecot version: 0.99.13-3 Debian sid) I use dovecot in combination with mutt, procmail and postfix. If I rename the last received mail I can use my inbox folder again (until the next time the index gets corrupted). Debian bug# 294284 -- make install, not war

[Dovecot] Server going crazy!!!
by poohba＠blkpoohba.dyndns.org 09 Feb '05

09 Feb '05

I have dovecot-0.99.11-1FC3.4. I use Pine on the server and Outlook 2003 on remote computers to access IMAP and POP3 to access via my blackberry 7100t. It seems that after using IMAP and then going back to pine it somehow refreshes everything and all the messages are picked up on my blackberry once again as if the emails are new. So everything that is in my inbox is now pushed or grabbed by my blackberry as new messages when they are not and have been read already (at least most of them). Why is this happening? ## Dovecot 1.0 configuration file base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s imap_listen = [::] pop3_listen = [::] imaps_listen = [::] pop3s_listen = [::] log_timestamp = "%b %d %H:%M:%S " login_dir = /var/run/dovecot-login login_chroot = yes login = imap login = pop3 default_mail_env = mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root

[Dovecot] Multiple auth sections, stable branch - 7/2/05
by Andrew Hutchings 07 Feb '05

07 Feb '05

Hi, Great job with the dovecot 1.0 stable branch, much more stable than the test57 I was using. Only one slight oddity, I know multiple auth sections is not stable yet but I am finding that one auth section at random is being ignored at login time (acknowledges it at startup). The auth section that is ignored is the same each time, but different on each server I use it on and changes at random after modifying the dovecot.conf file. Used both my test57 (hacked to remove the auth command) conf file and a new one I created using today's stable branch conf file. I sorted a work around by duplicating the failing auth sectio with a different name in each server and it works great! :) If this is easy thing to fix, great, you are still our hero either way Timo, you have made our mail server -> cluster migrations much less painless.

[Dovecot] Migrating from mbox to maildir: Message ordering?
by Ian R. Justman 06 Feb '05

06 Feb '05

Hi, all. I have been playing with the notion of migrating some of my folders to maildir because it's a lot easier to manage that way from a reader standpoint. The big question I have is how do I maintain message ordering in each folder? When I use a mail program to do the migration from mbox to maildir, selecting "order received ascending", it works nicely, but one very small problem: When I go to look at the newly-populated folder, everything is in reverse order. I've tried it with T'bird and I've tried it with Pine. Both yield the same results. I'm thinking the issue might be with Dovecot. Or is it a peculiarity with maildir? Or am I better off using other means to convert a mbox folder to maildir? I like maintaining the message delivery order so especially items like mailng list threads can (normally) flow right. I don't always trust the message's date field because it CAN be faked (and sometimes is by the sender, whether accidental or intentional). And while we're on the subject, since maildir's a file-per-message mailstore, what happens to ordering when you delete a message and a new message arrives? However, otherwise, everything else is working beautifully. I haven't gone into bashing the living hell out of it to make sure it REALLY works The testing was done with Dovecot 1.0test62, Thunderbird 1.0, and Pine 4.62. Both mbox and maildir folderstores are on the same machine and Dovecot's configured to use both with a maildir in the user's directory, oddly enough, called "maildir", for their maildir store. Thanks in advance for any help anyone can render. --Ian.

Hi all, Just wondering if anyone has successfully managed to configure pam_mkhomedir and dovecot, so that users home directories are automatically created? As far as I can tell, the login process runs as a non-root user, which results in a permission denied error while trying to create the users home directory. I'm not sure if this error is specific to dovecot or pam though. Any thoughts would be greatly appreciated. Thanks, Ben Halicki Information Technology Officer Macquarie Textiles Group Ltd Phone: 02 6043 0235 Fax: 02 60411 321 E-mail ben.halicki(a)macquarietextiles.com.au

[Dovecot] Dovecot doesn't call pam_open_session, thus dodging pam_mkhomedir
by Nicolas Lopez 03 Feb '05

03 Feb '05

I hit a small snag using Dovecot-imapd smoothly in my environment with maildir and most of my accounts in LDAP. Since the accounts are created through a web interface on another server home directories on the mail server don't get created automatically. There's the handy pam module pam_mkhomedir.so to automagically create home directories, but unfortunatly Dovecot wasn't calling pam_open_session to run the session setup pam modules. I made a small patch to passdb-pam.c to call pam_open_session between pam_acct_mgmt and pam_get_item and now I my home dirs are automagically created and everyone is happy. So, I figured I'd share the little patch in case someone else finds it useful. My patch doesn't properly close the session which will probably iritate more advanced session modules that actually have something to clean up, oh well. Aside from manually having to create home directories Dovecot-imapd has been working really well for us for a number of months, I just finally got around to dealing with the home dir creation issue. - Nick Lopez nlopez(a)espri.arizona.edu

[Dovecot] dovecot-stable branch
by Timo Sirainen 01 Feb '05

01 Feb '05

To confuse Dovecot versioning even more, I've added "dovecot-stable" module into CVS. This is a version of Dovecot before the recent keyword changes but with several bugfixes backported to it. It's thought to be mostly stable. I intend to keep it updated with important bugfixes and with other simple bugfixes. Although I'm not sure if I'll make a large code base upgrade once keyword changes are stable. This is mostly meant for people who _really_ want to use 1.0-test codebase in production right now. Perhaps it's already more stable than 0.99.x, but upgrading should probably be made easier for v1.0. The dovecot-stable module itself is just a hack that will go away at some point. Once the main codebase is stable enough for v1.0 beta release, I'll make a stable branch instead in the main dovecot module (and probably with different RCS than CVS).

[Dovecot] vpopmail oddities
by Allen Parker 01 Feb '05

01 Feb '05

vpopmail + qmail + dovecot + thunderbird = huge headache ;-) alright, when attempting to connect via imaps to my .maildir based vpopmail install, $user@$domain is having some problems. /var/vpopmail/domains/$domain/$user is the location of the user folders with vpopmail and yet dovecot isn't exactly passing on the domain :-\ i'm not sure if this is a pebkac issue or if it's the root of something far more evil, but this is really bothering me after about 4 days. i've got dovecot set to auth against vpopmail and i'm running a dovecot authd. i know that i've given very little information, is there any way that someone can ping me back requesting the particular information they need to properly diagnose this? -- ________________________________________ To avoid being added to my spam filter: 1.

[Dovecot] mbox vs maildir
by poohba＠blkpoohba.dyndns.org 01 Feb '05

01 Feb '05

I am a little confused and maybe if I figure this out I will be able to get this to work. I am now able to get my pop3 working but not imap. My inbox is in /var/spool/mail/%u and my mail directory is /home/%u/mail and then all the 'folders' are there which are actually files. Is that maildir or mbox? Which do I have to use for dovecot? Or can I use whichever I choose. I would like to keep the setup I have and use IMAP but i am finding this very difficult. I find some places that say I have to convert what I have and other places that say I don't. Can someone please break it down for me.

[Dovecot] How to run in debug format for SSL testing?
by Jeff A. Earickson 31 Jan '05

31 Jan '05

Help, new to dovecot... I want to get some output from my test sessions to confirm that SSL pop and imap are working. How does one get debug output from dovecot? How does one see that dovecot is using SSL in a transaction? I configured dovecot 0.99.13 with: CC=gcc CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl --with-rawlog --enable-debug > configure.out on Solaris 9. BTW, if I compile with Sun's StudioOne version 8 compiler, I get a core dump of dovecot-auth into /var/run/dovecot. The gdb backtrace looks like: gdb dovecot-auth core GNU gdb 5.2.1 Copyright 2002 Free Software Foundation, Inc.

[Dovecot] Corrupted mailboxes
by Vincent Jaussaud 31 Jan '05

31 Jan '05

Hello, We are currently facing some weird problems, and although it may not be directly related to dovecot, I hope some of you guys may have a clue on this. We used to have a POP/IMAP server running Fedora Core1, with dovecot 0.99.13 (DAG). Everything was working fine, until an hardware problem forced us to install a new server, on another machine. We installed a fresh new Fedora Core 3 box, running both sendmail 8.13.1, procmail 3.22 and dovecot 0.99.13. Now, we are seeing strange errors in our dovecot logfiles. It seems to happen randomely, but always on the same mailboxes. The following error is logged: pop3(username): Jan 27 17:26:46 Error: Error syncing mbox file /var/spool/mail/szameitatd: LF not found where expected pop3(username): Jan 27 17:26:46 Error: Error indexing mbox file /var/spool/mail/username: LF not found where expected pop3(username): Jan 27 17:26:46 Error: Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-01-27 17:26:46] People having that problem are able to login, but cannot retrieve new mails. Clients simply says no new mails are available. We tried to remove completely the mailbox file, waiting for procmail to create a new, but after a few minutes, the problem happens again. We cannot reproduce the bug with a particular mail; it seems the problem come from nowhere. Verbosing procmail didn't helped either. The only way to fix it when this happens, is to manually edit the file, and remove the first line feed at the very beginning of the mailbox file. I saw one post in the mailing list with the same problem, and we tried the "mail_extra_groups = mail" workaround, but that didn't help either. I actually think this has nothing to do with my problem :) We have around 500 mailboxes, and only a couple of them (3-5) do have the problem. Any idea how this can happen ? Any suggestions ? Thanks !

Hello list, is there a possibility to submit a query after a login. I use this feature in tpop3d to write a popb4smtp log into mysql. I would like to replace tpop3d with dovecot for pop3 and imap.

[Dovecot] Problem with incorrect permissions with shared folders
by Dave Hatton 30 Jan '05

30 Jan '05

Hi, I'm seeing strange permissions when using an email client to create a new sub folder in a shared folder. This is dovecot-1.0test61 I have a directory /data/mail/shared owner=root group=shared permissions=2770 I have a file /data/mail/shared/dovecot-shared owner=root group-shared permissions=2660 User fred in in group shared (in /etc/group) My understanding is that now in my client I can create a folder called test and so I should have Folder /data/mail/shared/.test owner=fred group-shared permissions=2770 What I actually get is Folder /data/mail/shared/.test owner=fred group-shared permissions=2700 So dovecot doesn't appear to be honouring the permissions on dovecot-shared when creating folders. Also, when creating a folder in a shared folder should the create process automatically copy the dovecot-shared file down to the new folder to allow this to be shared as well? Thanks Daveh

[Dovecot] Problem using passwd-file authentication: does not read UID, GID
by Joseph Tam 30 Jan '05

30 Jan '05

There seems to be a problem when setting the default authentication method to passwd-file when they use the same file (which they frequently do): auth default { mechanisms = plain userdb = passwd-file /passwd passdb = passwd-file /passwd ... } The log files show dovecot: Jan 11 14:41:40 Info: Dovecot v1.0-test60 starting up dovecot: Jan 11 14:41:49 Info: auth(default): userdb(test,127.0.0.1): uid=0 gid=0 home= mail= dovecot: Jan 11 14:41:49 Error: Logins with UID 0 not permitted (user test) dovecot: Jan 11 14:41:49 Info: imap-login: Internal login failure: test [127.0.0.1] When userdb-passwd-file.c::passwd_file_init() is called, it compares the userdb passwd-file to the passdb passwd-file. If they are the same, it resets the time stamp to force a re-read of the password database during the next look-up. However, I believe it also needs to reset the userdb_pwf->userdb flag to TRUE or else it won't pick up the UID and GID and will use 0 instead: /* resync */ userdb_pwf->userdb = TRUE; /* Was FALSE in v1.0-test60 */ userdb_pwf->stamp = 0; Joseph Tam <tam(a)math.ubc.ca>

[Dovecot] STARTTLS and inetd
by Magnus Holmgren 30 Jan '05

30 Jan '05

Hi! When running dovecot from inetd (as per the instructions on http://wiki.dovecot.org/InetdInstall) imap-login and pop3-login thinks that TLS is enabled when in fact it isn't (we're connecting to port 110 and port 143, so the --ssl parameter isn't present). The reason for that is found in login-common/main.c:main(): > if (fd != -1) > (void)client_create(fd, &ip, TRUE); I added a flag which I set when ssl_proxy_new() is successfully called (see the following diff) and it seems to work fine.
