[Dovecot] Wiki's MainConfig page

http://wiki.dovecot.org/MainConfig is now automatically generated from dovecot-example.conf, so it's no longer out of date. I use the attached perl script to generate it, so if you want some things to work better in it fix the script and send it back to me :) Oh and it's now immutable so no-one can edit the page directly.

When "login_process_per_connection = no" , always got "invalid I/O fd 8, callback 0x8064d30" error. from log file ( in dovecot.conf login_process_per_connection = yes): ...

[Dovecot] Dovecot 1.0beta7: STARTTLS/SSL not wanting to start
by Mike Brudenell 11 Jun '06

11 Jun '06

Greetings - I have been looking at Dovecot with a view to migrating us to it from the Washington IMAP server on our Sun systems. To start our testing we first of all installed the pre-built version of Dovecot from the Blastwave (www.blastwave.org) community supported packaged software site. This was Dovecot 0.99.10.4 and we successfully got it working in our test environment: at first just with regular IMAP, then with STARTTLS too. For the latter we installed a properly signed certificate and it works fine: mail clients can connect, use STARTTLS and then use the encrypted connection. I then downloaded the source code for Dovecot 1.0beta7 and built this myself from source, against the OpenSSL 0.9.8 libraries. I configured Dovecot to use the same certificate and key files as had been used for the earlier version we had just tried out. Whilst 1.0beta7 works fine for regular IMAP it just does not want to start SSL using STARTTLS at all. The error that is getting logged in the syslog file is: <date etc> ... dovecot: [ID 107833 mail.warning] imap-login: SSL_accept() failed: error:140D308A:SSL routines:TLS1_SETUP_KEY_BLOCK:cipher or hash unavailable [ddd.ddd.ddd.ddd] I see in the archived for the list archives that this same problem was asked about for 1.0beta3 but without a solution I could see. Could someone offer any insight/help, please?

[Dovecot] Quotas and LDAP
by Stephan Müller 11 Jun '06

11 Jun '06

Hi, first of all, it is very nice that dovecot has quotas now! Thank you very much. Now, I want to use quotas with LDAP requests, but I am having the following issues. First, contrary to what is written in the Wiki about quota and LDAP ("# quotaStorage must be in the format mentioned above, # For example: dirsize:storage=10240"), it is possible to have an LDAP field with just a number in it. The configuration in dovecot-ldap.conf looks like: user_attrs = homedir=home,uidnumber=uid,primaryGroupID=gid,quotanumber=quota=maildir:storage This works (as tested - I guess, it works as long as the quota entry is the last entry) and you also see it in the logs: Jun 11 19:10:36 inet dovecot: auth(default): master out: USER^I8^Ismueller^Iuid= 76340^Igid=513^Iquota=maildir:storage=90000000^Ihome=/home/dozenten/smueller/ Question now: is this intended (meaning, is this configuration possibility here to stay)? If yes, can you please update the wiki? Second issue: according to the description, the quota number is the size in KB. Is there a chance to change it to bytes? Reason: I am using Postfix with the VDA extension. There, the quota is to be given in bytes. Now, as lazy as I am, I only want to maintain one value for the quota. As I personally think that a quota given in bytes is more flexible, I would ask whether the following change can be made to dovecot: --- quota-maildir.c.orig 2006-06-11 19:15:55.000000000 +0200 +++ quota-maildir.c 2006-06-11 19:16:13.000000000 +0200 @@ -526,7 +526,7 @@ for (; *args != '\0'; args++) { if (strncmp(*args, "storage=", 8) == 0) { - size = strtoull(*args + 8, NULL, 10) * 1024; + size = strtoull(*args + 8, NULL, 10); if (size != 0) root->message_bytes_limit = size; root->master_message_limits = TRUE; Thanks Stephan -- | Those that bite the hand that feeds them are | | doomed to lick the boot that kicks them. |

[Dovecot] beta8: complaint about tilde at startup
by Jeff A. Earickson 11 Jun '06

11 Jun '06

Timo, After installing beta8 on Solaris 10 sparc and starting it for the first time, I noticed this in my syslog: May 14 19:35:45 emerald dovecot: [ID 475045 mail.info] Dovecot v1.0.beta8 starting up May 14 19:35:47 emerald dovecot: [ID 536776 mail.error] stat(~) failed: No such file or directory The only appearance of the tilde (~) in my dovecot.conf is here: default_mail_env = mbox:~/mail:INBOX=/var/mail/%1u/%u:INDEX=~ Is the INDEX definition wrong? Or is this a bug? My setup: Solaris 10, mbox format, home directories are local UFS filesystems, INBOX is an NFS-mounted filesystem from another S10 box (NFS version 4). Jeff Earickson Colby College

[Dovecot] maildir quota not including INBOX
by Bill Boebel 11 Jun '06

11 Jun '06

The maildir quota plugin doesn't appear to be including the INBOX in the quota calculation that is reported by GETQUOTAROOT. I took a look at the code and it appears that in this file "src/plugins/quota/quota-maildir.c", the function "maildirsize_recalculate" relies on all of the folders being listed when "maildir_list_init" is called. However the INBOX is not included in that listing, so its current storage size is not included. I couldn't figure out what patch would be needed to fix this, but I'm sure it is something simple. Any ideas? Bill

[Dovecot] LIST command ignores "hidden=yes" for default namespace
by Bill Boebel 11 Jun '06

11 Jun '06

I'm not sure if this is a bug or just an undesirable feature, but when I have our namespace configured to match Courier's "INBOX." functionality, Dovecot forces me to also define a default namespace (with no prefix). Without the default namespace defined I get "NO Unknown namespace." errors when trying to subscribe or unsubscribe folders. So I have configured my namespaces like this: namespace private { separator = . prefix = INBOX. inbox = no } namespace private { separator = . prefix = inbox = yes hidden = yes } However with this configuration, LIST commands ignore the "hidden = yes" setting on the default namespace and IMAP clients end up displaying an identical folder listing twice... 2 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.spam" * LIST (\HasNoChildren) "." "INBOX.Trash" * LIST (\HasNoChildren) "." "INBOX.Sent" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasNoChildren) "." "INBOX.RSS" * LIST (\HasNoChildren) "." "INBOX.test" * LIST (\HasNoChildren) "." "INBOX.test2" * LIST (\HasNoChildren) "." "spam" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "RSS" * LIST (\HasNoChildren) "." "test" * LIST (\HasNoChildren) "." "test2" 2 OK List completed. Again, I am not sure if this was intended, but either way it is undesirable for us. I even had a couple customers delete one of their duplicate folders thinking that was safe, but it deleted both folders - of course. To force Dovecot to hide mailboxes in the default namespace I made the following change: src/imap/cmd-list.c: @247 + if (ns->hidden) { + return; + }

[Dovecot] Bug: maildirsize not updated when deleting folders
by Bill Boebel 11 Jun '06

11 Jun '06

When using maildir++ quotas, if you delete an IMAP folder, the maildirsize file should get updated so that it subtracts the size of the messages that were contained in the deleted IMAP folder. However Dovecot is not doing this, resulting in Dovecot showing an incorrect quota value until the next time the maildirsize file is rebuilt. Bill
