[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. GDB is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions. Type "show copying" to see the conditions. There is absolutely no warranty for GDB. Type "show warranty" for details. This GDB was configured as "sparc-sun-solaris2.8"... (gdb complaints about lack of debug symbols from numerous libs snipped out) Core was generated by `dovecot-auth'. Program terminated with signal 10, Bus error. #0 0x0002b64c in pam_child_input () (gdb) backtrace #0 0x0002b64c in pam_child_input () #1 0x00036c68 in io_loop_handler_run () #2 0x00035e5c in io_loop_run () #3 0x00025940 in main () The code works when compiled with gcc 3.4.3.

[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. Therefor I would need something similar. Thanks for answers. Regards Karl-Heinz __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security.

[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. Is there any reason it shouldn't? What's the reason that the code is the way it is? -- Magnus Holmgren holmgren(a)lysator.liu.se P.S.

[Dovecot] Dovecot shared folder woes
by Dave Hatton 30 Jan '05

30 Jan '05

Hi I'm new to Dovecot so please be gentle with me. I did a search through the list archives but couldn't quite work out my problem. I have Dovecot installed and running and I can connect to it from my email clients (Outlook and Evolution) ... so looking good so far. I would like to setup three types (groups?) of mail store 1. A per user - e.g. Fred, Harry, Betty. (For my purposes they all have Unix Accounts on the mail server) 2. A public store which can contain folders that may be read and written to by any user who is authenticated 3. A per group store (e.g. accounts, sales, marketing) that may be read and written to by any user who is authenticated and is in the specified group Firstly, should this be possible with Dovecot? I have tried the following dovecot.conf parameters which I thought should do the trick ... --------------------- cut ------------------------- ### this should give each user a mail store default_mail_env = maildir:/var/mail/%lu/%u/Maildir ### Create Public mail store namespace public { separator = / prefix = Public/ location = /var/mail/public inbox = no hidden = no } ### Create mail store for accounts namespace shared { separator = / prefix = Accounts/ location = /var/mail/accounts inbox = no hidden = no } ### Create mail store for sales namespace shared { separator = / prefix = Sales/ location = /var/mail/sales inbox = no hidden = no } --------------------- cut ------------------------- I then: 1. created the directories /var/mail/{public,accounts,sales} 2. chgrp each one to a group (public,accounts,sales respectively) 3. chmod 770 each one 4. created a dovecot-shared in each one - chgrp and chmod appropriately And then restarted the server Now my problem When I try to connect from a client it fails and the tcp/ip connection dies When I look in /var/log/mail I see and error 89 (which I understand is a generic error) and IMAP(fred): Failed to create storage for 'Public/' with data: /var/mail/public What and I doing wrong? TIA Daveh
