[Dovecot] Feature request: Dynamic user lookup modules
by Mark Rosenstand 11 Dec '05

11 Dec '05

Hi, As a packager I'd think it would be way cool if the lookup modules that needs to link against external librarires (ldap, pgsql and mysql) could be loaded dynamically at run-time. Am I alone on this? :-)

Hi, I've been getting this bug in 1.0alpha4. It happens every time the user checks his Inbox. I'm using mbox btw. Can I get any hint on why this is happening?

[Dovecot] openssl > 0.9.f-4 a must for dovecot 0.99.14 ??
by Adrian Mak 10 Dec '05

10 Dec '05

My linux is Redhat AS3 U3, openssl is 0.9.7a-33 I downloaded dovecot 0.99.14 src rpm and rebuild to binary rpm Everything went smooth but I tried to install the dovecot binary rpm, it reported that openssl need >= 0.9.7f-4 Since there are many other rpm packages have dependency on the current version of openssl 0.9.7a-33, so It's not possible to upgrade openssl to 0.9.7f-4 or greater Is it a must to use openssl 0.9.7f-4 or greater in order to use dovecot 0.99.14 ?

[Dovecot] Order of emails
by Marcus Don 10 Dec '05

10 Dec '05

Hi We have an issue regarding the order in which emails are displayed in an imap folder, which our customers regularly complain about. By default, emails are returned from a folder in the order in which they were placed into the folder, which makes perfect sense. However, if an email is moved into another folder, it will always appear at the top, no matter how old it is. We could order the emails ourselves before displaying them in our webmail program. However, this would mean parsing the headers of every single email, which could be many thousands, so would slow things down considerably and greatly increase load. At the moment, we only read 30 at a time as the user pages through the folder. >From what I can see, the order is determined by the timestamp in the email filename, which gets updated every time the email is moved. Is there any way we could disable this, so the filename (or at least the timestamp part of it) remains constant? If so, would this affect in any way the behaviour of other imap clients, such as Outlook? All suggestions welcome.

[Dovecot] Squirrelmail/dovecot sort problem/bug
by A.P.Munnikes 10 Dec '05

10 Dec '05

Hello, there is a little bug in Squirrelmail 1.4.5 or Dovecot 1.0.alpha4-1: the sort is not correct if I use squirrelmail with the option: 10. Allow server thread sort : true 11. Allow server-side sorting : true with the option on false and with Thunderbird 1.5rc1 there is no problem, but I think Thunderbird 1.5rc1 already does the sort by itself. I have a folder with 1054 messages, but if I sort (from old to new) them in squirrelmail the newest 3 messages (received after the migration from thunderbird/pop3 to dovecot) are on the first page, before the messages from 5 month ago. 14:08 3.4 k (that is today 8 dec, 2005 ) 08:26 5.2 k + 00:07 2.9 k 8 jul, 2005 4.1 k 6 jul, 2005 3.5 k 3 jul, 2005 3.1 k 8 jul, 2005 4.1 k 6 jul, 2005 3.3 k 8 jul, 2005 3.8 k 5 jul, 2005 4 k 8 jul, 2005 7.4 k 11 jul, 2005 6.8 k Also my 'sent' folder: sorted from new to old contains on the last page 2 messaged that I send today (after the migration to dovecot) 12 jan, 2005 2.8 k 12 jan, 2005 1.7 k 11 jan, 2005 1.5 k 10 jan, 2005 1.1 k 8 dec, 2005 1.1 k ( <= send from thunderbird) 8 dec, 2005 1.6 k ( <= send from squirrelmail) And also an other mail folder has sorting problems. However my INBOX looks normal, while I received 5 or 6 messages after the migration. What have I done: *restarted apache2 a couple of times *restarted dovecot a couple of times *In the first folder (with >1000 messages) I already have deleted the dovecot files and new files are generated -rw------- 1 alfred alfred 17184 2005-12-08 23:41 dovecot.index -rw------- 1 alfred alfred 60416 2005-12-08 23:42 dovecot.index.cache -rw------- 1 alfred alfred 17908 2005-12-08 23:42 dovecot.index.log -rw------- 1 alfred alfred 10 2005-12-08 21:15 dovecot-keywords -rw------- 1 alfred alfred 40600 2005-12-08 23:41 dovecot-uidlist *closed webbrowser and restarted a new firefox 1.5 and surfed to squirrelmail. I don't know if this is a dovecot or squirrelmail problem. Alfred

[Dovecot] Update on Using Dovecot with Webmin
by Lee MSN 10 Dec '05

10 Dec '05

First of all thanks for the replies. I have decided to try the updated version 1.0 alpha After uninstalling Dovecot .99 and cleaning up user,groups and files. (Dovecot .99 was authenticating as best I can tell using unix users = the default -- and PAM = the default - I only had to setup the PAM if I remember correctly. Loaded Dovecot 1.0, made sure user, folders and files all seem to be setup correctly. Now - Webmin is able to stop and start Dovecot and it loads fine on reboot. But, it is pretty obvious that the Webmin modual is not up with then new and much more powerful Dovecot config file. For me that is OK, as long it will show weather the service is up or down - stop and start it, which is seems to be doing just fine. The reason I say this is when I try and use the Webmin modual to set user authentication to Standard Unix user database and PAM - it does not work. So I am needing help editing the Dovecot.conf file. My new problem is this: Can not get users to authenticate. I am trying to first setup just unix authentication - with plain text for starters then will move up to more secure. I have left the config file default - just made changes until it would start. With the notable execption I set plain text to yes. I have setup the Dovecot PAM file per the documentation. So what I need help now with is this I am wanting to setup a very simple setup to start with: A setup so that a outlook express client can login, using plain text password, unix login and password POP3 = yes Users = linux/unix (/etc/passwd) Passwords = PAM or Shadow Can anyone send me and edited config file that is setup to for this type of authentication? Or cut from their config file those sections needed for the authentication? Actually, if anyone is willing to share a config file that is setup with a more secure type of authentication that would be great too. (Thinking of switching to Cyrus - have any of you jump off of Cyrus to use Dovecot -- why??)

[Dovecot] Dovecot out of memory errors on Debian sid
by Ric 10 Dec '05

10 Dec '05

hi I have dovecot (1.0.alpha4-1) installed on a Debian sid amd64 machine (dovecot-imapd and dovecot-common). I am using this so that I can use both Mutt and something like Thunderbird to access my local Maildir folders. Sometimes it works fine. Sometimes when I try to access my mailboxes locally using Mutt, it hangs for a very long time (the bottom of the screen says "Selecting in..." (.in is the mailbox), and eventually gives me a blank mailbox with "(no mailbox)" at the bottom of the screen. In /var/log/mail.err I find lines like the following: Dec 3 06:39:02 localhost dovecot: child 4600 (imap) returned error 83 (Out of memory) Dec 3 06:44:03 localhost dovecot: imap(ric): pool_system_malloc(): Out of memory For example, it was working fine earlier this morning, but now I am unable to access the mailboxes and I'm getting the error messages in /var/log/mail.err. I have the same problem with Thunderbird; it hangs and cannot access the mailboxes. At my office I have dovecot (0.99.14-1) installed on a Debian sarge machine and it works fine. I would appreciate any suggestions as to what to try or what to look for. My dovecot.conf file is very simple: ## Dovecot 1.0 configuration file protocols = imap listen = localhost ssl_disable = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_extra_groups = mail protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb prefetch { } user = root } Thanks, Ric

[Dovecot] "Out of memory" error in 1.0alpha3
by Sergey A. Lipnevich 10 Dec '05

10 Dec '05

Hi All, I have Dovecot 1.0 Alpha3 running on x86_64 Linux 2.6 multi-CPU box using Maildir folders. Moving messages from one folder to another in Thunderbird 1.0.7, regardless of their size (usually small), produced error 83, "Out of memory", when both of these parameters were unset (default): mail_read_mmaped, mmap_disable. The log line before the error was pool_system_malloc(): Out of memory. I initially changed mmap_disable to "yes", the error stopped, but it still wasn't moving messages reliably. I then set MM parameters more aggressively: mail_read_mmaped = yes, mmap_disable = no (and the third of the series, mmap_no_write, is left unset). The error stopped popping up, and the moving works speedily. Maybe the default for mail_read_mmaped should be "yes?" Thank you! Sergey.

[Dovecot] yet another update of the Dovecot AUTH patch: 20051208
by /dev/rob0 09 Dec '05

09 Dec '05

Wietse won't sit still ... removal of the lmtp(8) client broke the previous issue of the revised Dovecot AUTH patch. So I just redid it for the 20051208 snapshot: http://www.nodns4.us/postfix-2.3-20051208-dovecot-auth.patch.gz $ md5sum *gz ; ls -l $_ 32946afa424b3fbc04c8d9822e711e1f postfix-2.3-20051208-dovecot.patch.gz -rw-r--r-- 1 rob0 console 7287 2005-12-09 17:09 postfix-2.3-20051208-dovecot.patch.gz The original patch is here: http://dovecot.org/patches/postfix/postfix-2.2.1-dovecot-auth.patch Instructions are here (and don't forget the Postfix SASL_README too): http://dovecot.org/patches/postfix/README NB: Although my own postfix-2.3-20051208 snapshot compiled with the patch and is running, it is not tested at all. I'll try with AUTH later and see if it's working. I will not be able to test with LMTP. IIUC how this patch affects LMTP, it's only in that the USE_SASL_AUTH flag was changed to USE_SASL_CLIENT_AUTH. So the only people affected would be ones who are using Cyrus-SASL for client AUTH. Please let me know via either list (or offlist, see .sig) if you use this and have any problems. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
