[Dovecot] Error starting dovecot
by Diego Ledesma 08 Sep '08

08 Sep '08

Hello, I have a linux system (Ubuntu 7.04 server edition) running Postfix 2.3.8 Today i installed Dovecot through apt-get (got version 1.0.rc17 installed) and configured it to do sasl auth only, (i already have other pop3,smtp and imap servers running) following the howto's at dovecot.org The thing is that if i try to start dovecot or run dovecot -n i get this message: Error: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory That directory does not exist but why should it if i don't want to run dovecot as imap? I only installed dovecot-common package. Also, i setted protocols to "none". Does anyone know why i get that error message? One last comment. Before installing dovecot on the production mail server i installed it on my laptop's linux (Ubuntu 8.04 LTS) for testing purposes. The testing mail server runs Postfix 2.5.1 and Dovecot 1.0.10 and in this case Dovecot runs fine (the /usr/lib/dovecot/imap directory does also not exist and dovecot.conf is configured exactly on both servers). This are the uncommented parts of dovecot.conf #Only use dovecot-auth protocols = none disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:~/Maildir mail_privileged_group = mail protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain login passdb passwd-file { args = /etc/passwd.dovecot } passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } ---- Any help is greatly appreciated. Thanks. Diego.

Sorry, bounced this the first time ;( Darren I'd happily switched to a real cert if I knew that this was the problem. Are you using the cert actually on the phone to validate its identity? I have the org unit set slightly differently on my fake CA and the phone to make netscape derived browsers happy. The trouble is that I'm not getting a useful enough error message from anyone to diagnose problem. I have also considered putting my fake CA cert on the phone to see if that would make it happier, Darren >Charles Marcus wrote: >>You're not using self-signed certs by any chance? >> >> > >I have had good success using the cheapo certs from GoDaddy - they >offer a cert with multiple Alt names so you can connect using a >variety of server names.

[Dovecot] Cosmetic issue with dots in Maildir folder names
by Holger Weiss 07 Sep '08

07 Sep '08

Just a minor cosmetic issue: We use the listescape plugin in order to support "." characters in Maildir++ folder names, and in at least the following case, the escaped representation of the dot character ("\2e") won't be translated back to a "." in messages for the IMAP client: | 1 SELECT non.existent | 1 NO Mailbox doesn't exist: non\2eexistent However, SELECTing an existing folder whose name includes a dot works fine, and it also works in other cases, e.g.: | 2 CREATE does.exist | 2 OK Create completed. | 3 LIST "" does.exist | * LIST (\HasNoChildren) "/" does.exist | 3 OK List completed. This is with Dovecot 1.1.3; we use "separator = /" and we've defined REAL_SEP to '.' and VIRTUAL_SEP to '/' in the plugin. Holger

[Dovecot] ACL plugin: k permission and sub-subfolders
by Heiko Schlichting 07 Sep '08

07 Sep '08

Hi, I'm trying to disallow the creating of subfolders for some special folder for all users. Using ACL plugin for this seems to work at first glance but is not a full solution or is buggy as it allows the creation of sub-subfolders. I'm using the following ACL and namespace separator is "/": $ cat folder owner lrwstie Note: no "k" permission ("k" = create = Mailboxes can be created under this mailbox) Seems to work: a001 create "folder/subfolder" a001 NO Permission denied But: a002 create "folder/subfolder/subsubfolder" a002 OK Create completed. This is unexpected. Creating a subfolder is not allowed but a sub-subfolder is permitted? If this is intentional, the description in the wiki should mention this. And: How to disallow the creation of any subfolders and any sub-subfolders? Using "folder/.DEFAULT" instead of "folder" to define the ACL does not make any difference for the behavior. My configuration of dovecot is below the signature. Thanks, Heiko.

[Dovecot] v1.1.3 released
by Timo Sirainen 05 Sep '08

05 Sep '08

http://dovecot.org/releases/1.1/dovecot-1.1.3.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.3.tar.gz.sig This fixes several mbox problems previous v1.1 releases have had. * mail_max_userip_connections limit no longer applies to master user logins. + login_log_format_elements: Added %k to show SSL protocol/cipher information. Not included by default. + imap/pop3-proxy: If auth_verbose=yes, log proxy login failures. + deliver: Added -s parameter to autosubscribe to autocreated mailboxes. - message parser fixes - hopefully fixes an infinite looping problem - SORT: One more assert-crashfix when renumbering index sort IDs. - mbox: Saving may have truncated the mail being saved - mbox: Several other bugfixes - mail_full_filesystem_access=yes was broken when listing mailboxes (it still is with maildir++ layout). - maildirlock utility was somewhat broken - zlib plugin: bzip2 support was somewhat broken - NFS: Make sure writing to files via output streams don't assert-crash when write() returns only partial success.

[Dovecot] Time Moved Backwards Error Keeps Happening
by JackyC＠umac.mo 05 Sep '08

05 Sep '08

Hi all, I am running dovecot version 1.1.1 (dovecot --version) and keeps to have time moved backwards problem. I first found dovecot dead without obvious error message, but see the following when restart dovecot service by # service dovecot restart >Stopping Dovecot Imap: [FAILED] >Starting Dovecot Imap: Warning: Last died with error (see error log for more information): Time just moved backwards by 4398 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards [ OK ] I followed the above official wiki link and apply the ntpd service for adjusting the server timestamp. After running the ntpd service, I found the server timestamp drift is only 14.333 microsecond, I think which would be reasonable. But I still get the captioned error. Does anyone have the same experience? BTW, I couldn't find the error log message even I confirmed the info, error and debug log file by visiting this wiki document http://wiki.dovecot.org/Logging, does it really not log at the log file? I can just keep monitoring the log and use the following command to determine whether dovecot is running or not. # service dovecot status Thank you very much! Yours Sincerely, Jacky, Hoi Kei Chan,

My company's current system (unfortunally) uses that non-standard format. The MTA writes in that format. I guess it would require a patch then? tks. gpg

[Dovecot] filename format question
by Giorgenes Gelatti 05 Sep '08

Hello, Is it possible to configure the filename format in dovecot? For example, to change from "unique,W=size:2,FLAGS" to "unique,size.hostname:2,FLAGS_unique2"? Thanks in advance.
