[Dovecot] Dovecot / Exim with Multiple Domiains
by Marc Perkel 10 Feb '09

10 Feb '09

I'm using a very old scheme for doing multiple domains using an old Linuxconf based setup. Each domain has it's own passwd/shadow file. It works but I need something new and modern and has a web interface and perhaps a mysql backend or something else good. So - what are people using out there for managing email users and domains? Thanks in advance.

[Dovecot] Imap unlink "failed, is a directory".
by Dovecot＠corwyn.net 09 Feb '09

Dovecot 1.1.8-0_85.el5 I'm seeing this set of messages repeat every 15 min. My best guess is the user tried to delete an imap folder and is failing? Feb 9 20:05:58 mailserver dovecot: imap-login: Login: user=<user(a)example.com>, method=PLAIN, rip=10.0.0.1, lip=192.168.250.80, TLS Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): unlink(/var/spool/mail/example.com/user/Maildir/cur/cur:2,ST) failed: Is a directory Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): unlink(/var/spool/mail/example.com/user/Maildir/cur/new:2,ST) failed: Is a directory Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): Disconnected: Logged out bytes=66/623 From here: http://wiki.dovecot.org/VirtualUsers#homedirs I suspect it's a problem with access to the home directory. The users have a home directory: /var/spool/mail/domain/user (or at least that's where Maildir ends up). vuser has 700 access to that entire structure (everything under var/spool/mail/).

[Dovecot] Authentication woes.
by Roderick A. Anderson 09 Feb '09

09 Feb '09

I'm still searching but hoping someone can offer a clue-stick. Long story short! I had a server crash suddenly and all I can get at are the files. Built a new host and copied the data and config files over, correcting ownership and permissions (hopefully) as I went. But now I can't get logged in. Messages in /var/log/dovecot/dovecot-info.log, without saslauthd running, are like this. dovecot: Feb 03 08:55:46 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:48 Info: auth(default): client out: FAIL 1 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:48 Info: auth(default): client in: AUTH 2 PLAIN service=IMAP secured lip=216.64.180.226 rip=66.193.34.88 resp=AHJhYW5kZXJzQGFlc29mdC1zYmNzLmNvbQBrNnpiZTQy dovecot: Feb 03 08:55:48 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:50 Info: auth(default): client out: FAIL 2 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:54 Info: imap-login: Aborted login: user=<raanders(a)aesoft-sbcs.com>, method=PLAIN, rip=66.193.34.88, lip=216.64.180.226, TLS The passwd file exists and I'm using the correct password. dovecot -n as an attachment.

[Dovecot] Dovecot 1.1.11 segfaults on auth configuration error
by Sebastian Kayser 09 Feb '09

09 Feb '09

Hi, i have compiled & packaged Dovecot 1.1.11 on Solaris 8 x86 with Sun Studio 11 and installed the result on Solaris 10 x86 zone. When i now configure auth mechanisms other than "login" or "plain" while only providing pam as the passdb, Dovecot segfaults on startup. I know that my configuration is wrong here, but i guess this still qualifies as a bug. Remedy would be appreciated. # /opt/csw/sbin/dovecot -F dovecot: Feb 06 22:56:24 Info: dovecot v1.1.11 starting up dovecot: Feb 06 22:56:25 Error: child 26870 (auth) returned error 89 (Fatal failure) Segmentation Fault (core dumped) # /opt/SUNWspro/bin/dbx -f /opt/csw/sbin/dovecot core (dbx) where =>[1] hash_lookup(table = (nil), key = 0x68f6), line 159 in "hash.c" [2] child_process_lookup(pid = 26870), line 31 in "child-process.c" [3] log_it(log_io = 0x80b8598, line = 0x80b7d4a "DIGEST-MD5 mechanism can't be supported with given passdbs", continues = 0), line 129 in "log.c" [4] log_write_pending(log_io = 0x80b8598), line 52 in "log.c" [5] log_read(log_io = 0x80b8598), line 191 in "log.c" [6] log_deinit(), line 331 in "log.c" [7] auth_process_destroy(p = 0x80b86f8), line 357 in "auth-process.c" [8] auth_process_input(process = 0x80b86f8), line 244 in "auth-process.c" [9] io_loop_handler_run(ioloop = 0x80b3518), line 204 in "ioloop-poll.c" [10] io_loop_run(ioloop = 0x80b3518), line 336 in "ioloop.c" [11] main(argc = 2, argv = 0x80478dc), line 599 in "main.c" # /opt/csw/sbin/dovecot -n # 1.1.11: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc log_path: /dev/stderr login_dir: /var/opt/csw/run/dovecot/login login_executable: /opt/csw/libexec/dovecot/imap-login auth default: mechanisms: plain digest-md5 debug: yes passdb: driver: pam userdb: driver: passwd Please let me know in case there is any other information required to nail down the culprit.

[Dovecot] [patch] 'c' and 'd' in setacl
by Sascha Wilde 09 Feb '09

09 Feb '09

Hi Timo, Hi *, I just recognized that the new imap-acl plugin in dovecot 1.2 does not know the obsolete rights 'd' and 'c' when setting. According to RFC 4314 section 2.1.1.: If a client includes the "d" right in a rights list, then it MUST be treated as if the client had included every member of the "delete" right. and If a client includes the "c" right in a rights list, then it MUST be treated as if the client had included every member of the "create" right. Unfortunatly there are actually clients which depend on this behavior. I attached a rather rough[0] patch which implements this. cheers sascha [0] I don't like the use of static indexes witch imap_acl_letter_map but currently I wasn't able to decide on a more elegant solution. -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Rebuild folder listing?
by Roderick A. Anderson 09 Feb '09

09 Feb '09

I don't know what to call what I'm trying to do so I'll explain the situation. I had a total complete crash of the Linux-Vserver system that was hosting a Postfix+Dovecot guest with a three domains and 1-5 accounts per domain. Lots of mail though. Before it completely melted down I as able to get to the data (messages) and save them and the configuration files for both Dovecot and Postfix. I now have a replacement system up and running and have copied the directories onto it. I can log in to the accounts but I don't see the folders (I use Thunderbird as a MUA). Attempts to "subscribe" and "refresh" the list give me no results. No list of folders. What should I do? I'm thinking I could delete the dovecot files: dovecot.index, dovecot.index.cache, dovecot.index.log, dovecot-uidlist, subscriptions, and while I'm at it possibly dovecot-keywords. Then access the account(s) and Dovecot will rebuild them with the true/correct information. Am I heading anywhere near the right direction? TIA, Rod --

Re: [Dovecot] Disconnected Log messages I'd like to disable?

I understand what the log message means. I currently have dovecot logging flipped up about as high as I can have it set in about every way that I can. What I'd like to know is which logging setting can I lower to not see this message (or if there is one), and what OTHER things won't log if I decrease that logging setting. thx. rick At 08:43 AM 2/9/2009, Steffen Kaiser wrote: >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 > >On Mon, 9 Feb 2009, dovecot(a)corwyn.net wrote: > >>Feb 9 08:06:52 mailserver dovecot: IMAP(user(a)example.com): >>Disconnected: Logged out bytes=479/51185 > >Search the archive for a mail from Timo few times ago, it just means >that the user logges out (LOGOUT command). > >Bye, > >- -- Steffen Kaiser >-----BEGIN PGP SIGNATURE----- >Version: GnuPG v1.4.6 (GNU/Linux) > >iQEVAwUBSZAzIHWSIuGy1ktrAQKQDQf/S0zCmCuQ+xtJI0o3goUdDo0++yGXRyCp >fGdDKQ7YnOL1VOM1FnBjGJkhfYs/K6WuVFqQzqVrBjCoItsFWIvZCoeGWeHYPQf1 >6qRYngFSJLfdFDg9Ift5UvCnIS9W5jYv6otkJlddoH0SHeypSb9RZbPR20Ywf2da >whV4bB41W8ys/upUkaBd7+gKKcYcbSp+l3ZBXCrLnDbj7pCISnv2sENkTz2df1eE >wQSgpnbazmr9ePCx1cWDdvN5Wy9RN5KoGc+H0axtI7Uav5tkP7nVJ8GSmqBBH54r >nkvOrtmAjTMwp4MbYh6x2wejZJAY8lp72wQOeg3sJak32f3la0ZLgw== >=mLed >-----END PGP SIGNATURE-----

[Dovecot] v1.1.11 released
by Timo Sirainen 09 Feb '09

09 Feb '09

http://dovecot.org/releases/1.1/dovecot-1.1.11.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.11.tar.gz.sig Hopefully this v1.1 release will last a few months. - IMAP: PERMANENTFLAGS list didn't contain \*, causing some clients not to save keywords. - dbox: INTERNALDATE and save date was returned wrong for converted maildir files. - auth: Using "username" or "domain" passdb fields caused problems with cache and blocking passdbs in v1.1.8 .. v1.1.10. - userdb prefetch + blocking passdbs was broken with non-plaintext auth in v1.1.8 .. v1.1.10. - If mail_chroot is set, don't fail at startup in dump-capability.

[Dovecot] Maildir structure question
by Nicolas KOWALSKI 08 Feb '09

08 Feb '09

Hello, About the INBOX location when using maildir, in the wiki, http://wiki.dovecot.org/MailboxFormat/Maildir, I can read: " Directory Structure ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX. The tmp directory is used during delivery, new messages arrive in new and read shall be moved to cur by the clients. " But in my Maildir, I see this: niko@petole:~$ ls -la Maildir/ total 144 drwxr-xr-x 35 niko niko 4096 2009-02-06 08:37 . drwxr-xr-x 25 niko niko 4096 2009-02-06 10:26 .. drwxr-xr-x 5 niko niko 4096 2009-02-06 09:16 .INBOX ... There are no 'cur', 'new' and 'tmp' directories in ~/Maildir, as written in the wiki, but instead this .INBOX directory which contains these 'cur', 'new' and 'tmp'. Is this expected ? Thanks.
