[Dovecot] Sieve force SSL
by Lukas Haase 23 Sep '10

23 Sep '10

Hi, I have activated only imaps and managesieve. As sieve is running on a different port/protocol: Can I make sure that sieve can ONLY be used with SSL/TLS? As the credentials are transmitted I only offer services with SSL (IMAPS, SMTP over SSL, ...). For sieve I am not sure about this. If there is the possibility that user's credentials are transmitted in plain text I would block the port from the firewall, else I would offer my users the feature to change their rules with their own client (e.g. Thunderbird sieve). Regards, Luke

[Dovecot] Dovecot LDA, virtual users, multiple uids: No luck
by Toni Mueller 23 Sep '10

23 Sep '10

Hi, I'm trying to get Dovecot's deliver to create and use mailboxen with one uid per user. Reading the wiki, I decided to go with the sudo attempt, but I'm stuck because deliver fails to create the intermediate directories. The auth.log has this on the matter: sudo: dovelda : TTY=unknown ; PWD=/var/spool/postfix ; USER=root ; COMMAND=/usr/lib/dovecot/deliver -f toni(a)bogus.oeko.net -d dick(a)example.com Using strace on 'deliver', I get this: # su - dovelda $ echo "blubber" |sudo strace /usr/lib/dovecot/deliver -f toni(a)bogus.oeko.net -d dick(a)example.com ... geteuid() = 0 getgid() = 0 setgid(2000) = 0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ setgroups(1, [2000]) = 0 setuid(2100) = 0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ setuid(0) = -1 EPERM (Operation not permitted) getgid() = 2000 getegid() = 2000 setgid(0) = -1 EPERM (Operation not permitted) close(6) = 0 geteuid() = 2100 geteuid() = 2100 and subsequently, creating the directories fails. The values in the underlined lines above, 2100 and 2000, are from the database entry of the user I want to deliver the email to. My /etc/sudoers has this for dovelda: dovelda ALL=NOPASSWD:/usr/lib/dovecot/deliver dovelda ALL=NOPASSWD:/usr/bin/strace I'm using a Debian/Lenny system with amd64 and this package for Dovecot: # dpkg -l 'dovecot*' Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii dovecot-common 1:1.2.13-1~bpo secure mail server that supports mbox and ma ii dovecot-imapd 1:1.2.13-1~bpo secure IMAP server that supports mbox and ma Kind regards, --Toni++

[Dovecot] Sieve error on Quota full (Dovecot 2.0.3)
by Cassidy Larson 23 Sep '10

23 Sep '10

Just switched my storage boxes to 2.0.3 with Pigeonhole. Noticing for those that have quota fulls, my syslog is getting full of errors from sieve: dovecot: lda(user(a)host.com): Error: sieve: script /data/mail/host.com/user(a)host.com//.dovecot.sieve failed with unsuccessful implicit keep (user logfile /data/mail/host.com/user(a)host.com//.dovecot.sieve.log may reveal additional details) Checking the .dovecot.sieve.log I see: sieve: info: started log at Sep 22 00:38:11. error: msgid=<dovecot-1285137490-378260-0(a)storagebox.host.com>: failed to store into mailbox 'INBOX': Quota exceeded ( mailbox for user is full). Any way to suppress these quota full messages from filling up my logs and .dovecot.sieve.log ? I do like the .dovecot.sieve.log for debugging, but regular quota warnings seems excessive. Thanks, Cassidy

[Dovecot] Vpopmail support broken
by Matt Brookings 23 Sep '10

23 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 My apologies if I'm posting for information which has already been supplied to the list. I searched and all I found was people talking about the change in 2.0.3, but no details on the commit other than "I was tired of people telling me it crashes". We have not received any reports for the 5.4 or 5.5 branch of vpopmail causing crashes in Dovecot. That being said, if there is a problem, we would like to provide a fix. Again, if details on the specifics of the problem have been supplied, I apologize. Can anyone please provide me some reproduction details for Dovecot 2.0.3's vpopmail plugin compiled against vpopmail 5.4.30+ or 5.5.0? Removing the "vpopmail support broken" line from the configure script, compiling and running seemed to work short-term. I was able to authenticate against the vpopmail plugin. I tested with vpopmail 5.4.32 and 5.5.0 using the cdb authentication module.

[Dovecot] xz compression support
by Attila Nagy 23 Sep '10

23 Sep '10

Hello, Just wondering: Dovecot has gzip/bzip2 compression/decompression support. According to this: http://stephane.lesimple.fr/wiki/blog/lzop_vs_compress_vs_gzip_vs_bzip2_vs_… gzip and bzip2 aren't really useful together. While gzip can offer speed and a reasonable amount of compression ratio, bzip2 is slow, especially on decompression, which Dovecot does more frequently than compression (1 vs many). So: is it planned to include xz (liblzma) support? It would be useful especially for compressing old mails in the background (due to the resource intensity of the compression phase). Thanks,

[Dovecot] Panic: file mailbox-list-fs.c
by Burckhard Schmidt 22 Sep '10

22 Sep '10

Hi, I have dovecot 2.0.3. Mailboxes have been converted with dsync from mbox to maildir last week. There it was still version 2.0.2. A user "produces" now this error: imap(userx): Panic: file mailbox-list-fs.c: line 150 (fs_list_get_path): assertion failed: (mailbox_list_is_valid_pattern(_list, name)) Error: Raw backtrace: follows. And all other imap processes are closing down. dovecot starts again. master: Info: Dovecot v2.0.3 starting up Additional mail_location = maildir:~/maildir:INDEX=/addons/index/%u:CONTROL=~/control:LAYOUT=fs namespace { inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } Are there charachters which are not allowed or is there a reached a maximal length? regards -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] "Documentation" link from http://www.dovecot.org/
by William Blunn 22 Sep '10

22 Sep '10

On the Dovecot home page http://www.dovecot.org/ we have a link "Documentation" which links to the Dovecot 1.x wiki ( http://wiki.dovecot.org/ ). There is a question mark in my mind as to whether that is a good idea considering as how the current stable version of Dovecot appears to be 2.0.x. In the Dovecot 1.x wiki, there is a pink stripe across the top of the page which says that the documentation is for Dovecot 1.x. It looks as though the intention was to make that prominent so as to guide visitors to the right documentation, and I think to a certain extent it may work. But I am wondering if perhaps the stripe could be too easily missed. People might start browsing around in the Dovecot 1.x wiki without it even occurring to them that there was a whole another wiki for 2.x. I have an idea: Perhaps the "Documentation" link on the home page could be re-worked to something like Documentation v2.x v1.x where "v2.x" and "v1.x" are links to the two wikis. This would make it obvious that there was different documentation available for v2.x and v1.x, and encourage visitors to choose the appropriate set. Bill

[Dovecot] service(imap-login): chiled ... killed with signal 11
by Burckhard Schmidt 22 Sep '10

22 Sep '10

Hi, dovecot 2.0.3 After closing the imap(s) connection dovecot crashes: imap-login: Info: Aborted login (no auth attempts): rip=... lip=... mpid=0 master: Error: service(imap-login): child 18636 killed with signal 11 (core not dumped - set service imap-login { drop_priv_before_exec=yes }) master: Warning: Killed with signal 15 (by pid=18643 uid=0 code=kill) It also happens if I only telnet to the imap(s) port and give the only command "1 logout". How can I get a dump for backtracing? With drop_priv_before_exec=yes I get a config error: doveconf: Fatal: Error in configuration file /usr/dovecot/etc/dovecot/dovecot.conf: service(imap-login): drop_priv_before_exec=yes can't be used with chroot As user I can login and work normaly but I have to reconnect after a differnet connection will be closed causing a dovecot crash. Additional information: Solaris 10, packages openssl, openldap by opencsw I had seen a similar error during login process already with an rc-version. Because opencsw offers only an older version of openssl I installed current versions of openssl and openldap, So it works again. Now both packaged are up to date at opencsw. So I would like using these packages again when I install dovecot. Any hints? -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] Support for spaces in plaintext passwords?
by Simon 22 Sep '10

22 Sep '10

Hi! I have problems with my cellphone. It does not seem to quote the strings to the login command. I can logon using ie SquirrelMail but if i try to login using AndroidMail it just says "autentication failed". If i try maualy i get similar results. Changing password for test to "password-" a login test password- a OK Logged in. Changing password for test to "password " * OK Dovecot ready. a login test password #here i type "password ", but without "" a NO Authentication failed. Uppon examining squirrelmails comunication it sends login "test" "password " I will of cause file a bugreport that Android Mail should use quoted strings when using 'login' autentication as per rfc2060 (which seems to allow it but not demand it). But i wonder if it is possible to work around this issue in Dovecot somehow?
