[Dovecot] AppleMail causes dovecot error: file mbox-rewrite.c: line 429 assertion failed
by Adam Rosi-Kessel 29 Nov '04

29 Nov '04

I get the following error message in my syslog frequently when a user accesses the dovecot (IMAP) server from his OS X AppleMail client: Nov 24 09:45:42 myhost imap(someuser): file mbox-rewrite.c: line 429 (mbox_write_header): assertion failed: (hdr_parsed_size.physical_size == hdr_size) Nov 24 09:45:42 myhost dovecot: child 23277 (imap) killed with signal 6 Usually each message appears 5-6 times. The user on the other end doesn't notice any problems. Any idea why this occurs and what I can do to prevent it? I'm using dovecot from Debian sid, 0.99.11-3. Otherwise a fairly standard configuration. -- Adam Rosi-Kessel http://adam.rosi-kessel.org

[Dovecot] Runtime root directory
by Brad Robel-Forrest 28 Nov '04

28 Nov '04

I'm considering modifying the Dovecot source to support a runtime designation for the root directory instead of relying on the prefix provided via configure. Once complete, it would be possible to move the root directory around somewhat ad-hoc after installation without having to rebuild the source. The primary driver for this is that I'd like to wrap a binary build of Dovecot within an OSX application bundle. These bundles can be placed anywhere the user desires, so Dovecot couldn't rely on a particular build-defined root directory. Before I get too far down the path, I'd like to know if there's a desire for this type of enhancement. If so, I'd like to provide a diff that would meet any other requirements for this change. There are two methods I was considering. Feel free to suggest a better alternative as I'm not ecstatic about either at the moment. 1. Find and change all uses of the prefix directory to instead prepend a value obtained from the environment (say, DOVECOT_ROOT_DIR). 2. Find and change all uses of the prefix directory to instead prepend a value obtained from the configuration file (say, a new setting called "dovecot_root_dir"). In either case, if the value was not available or not a valid directory, I would fall back to the build prefix. I would also make this functionality optional via configure--defaulted "off". -brad

[Dovecot] Dovecot 1.0-test52 and LDAP authentication
by Jonathan Salomon 26 Nov '04

26 Nov '04

Hi all! I have upgraded Dovecot 0.99.11 installation that's worked with LDAP to Dovecot 1.0-test52 and I can't get LDAP to work. I noticed the /etc/dovecot.conf is slightly different, so I have adjusted changes. If I use the standard auth (passw & pam) everything works fine, however when I user ldap for auth Dovecot starts but then dies: dovecot: Nov 26 14:14:36 Error: Auth process died too early - shutting down dovecot: Nov 26 14:14:36 Error: child 16454 (auth) killed with signal 11 As far as I can tell the /etc/dovecot-ldap.conf hasn't changed since 0.99.11 and the LDAP server is working properly. What is happening here? I did a 'strace -f dovecot 2>log' because I saw this in the mailing list archive, but it doesn't really tell me anything, so I have someone can tell me what is happening here. I have included the tail below. Thank you in advance!

[Dovecot] [OT] Apple Mail.app access to localhost imap when no network
by Alan Schmitt 25 Nov '04

25 Nov '04

Hello, Sorry for the offtopic subject, but I tried asking this on some Apple mailing lists and could not find an answer there, and as it's related to imap (provided by dovecot), someone might know something about this. The problem is the following: I have a local IMAP server provided by dovecot, so that I can store my mail in maildir format, and read it both using mutt and Apple Mail.app. Mail.app is configured to access localhost:143 to access mail. However, I discovered that when there is no network connection (no ethernet cable plugged in and no wifi network), Mail.app is saying that it's working in disconnected mode and refuses to access the imap server. Would someone have a suggestion as to what to do to allow connected access to localhost when no network is present? I'm very new to OS X (I come from Linux). Thanks a lot, Alan Schmitt

Re: [Dovecot] dovecot only answers to imap connections
by Mitch Pirtle 25 Nov '04

Nope, just sticking with simple pop3 at this point ;-) The second issue I am having is that Thunderbird seems to 'freeze' from time to time on directories that have more than 1000 messages in them. I remember reading earlier that there were some performance tweaks for Thunderbird, but I lost the link :-( I cannot replicate the authentication problem, and will wait to see if it is a layer 8 protocol error (between the ears). Thanks for the help, you have been stupendous! -- Mitch On Wed, 24 Nov 2004 19:01:29 -0700, Saurabh Barve <sa(a)atmos.colostate.edu> wrote: > Are you using simple POP3 or secure POP3?

[Dovecot] Cannot see contents of ~/mail folder
by Saurabh Barve 25 Nov '04

25 Nov '04

Hi, I just installed dovecot-0.99 on my Fedora Core 2 machine. When I start the secure IMAP daemon, I am able to see my Inbox, but not the other folders in the 'mail' folder in my home directory (sent-mail, saved-messages, etc.) These folders were created when I was using pine earlier on the machine. In my dovecot.conf file, I have set: default_mail_env = mbox:~/mail:INBOX=/var/mail/%u I am using Mozilla Mail as my mail client, if that makes a difference. Dovecot seems to be creating a directory called .imap inside the 'mail' folder, where it is storing the inbox and a Trash folder. I have set "mail_full_filesystem_access = no" so that users don't access any of their other files except the mail folder. From what I understand, I don't have to set IMAP path in Mozilla Mail. I tried doing that too, just to try it out, but as expected, it didn't work. What do I need to set in order to see my other folders in the 'mail' directory?

[Dovecot] ssl_ca_file
by Jacob Elder 24 Nov '04

I am very fond of Dovecot, but it would be nice to have a more useful SSL implementation. When do you think we'll see a non-beta version that supports ssl_ca_file? I am running 0.99.11-3 from Debian testing. -- Jacob Elder

[Dovecot] Error in IMAP command GETACL: Unknown command..
by Ingo Lantschner (Lists) 24 Nov '04

24 Nov '04

Hi all, I have just installed dovecot on my Fedora Core 2 box. I would like to use it only for reading archived email from within my Mozilla 1.7.3. I syminked my old opera-files (*.mbs whoch seems to be same as mbox) into ~/mail. Seems to work fine, mostly I can open the mailfiles - sometimes it hangs with the following error: The current command did not succeed. The mailserver responded: Error in IMAP command GETACL: Unknown command.. And then: The current command did not succeed. The mailserver responded: Error in IMAP command MYRIGHTS: Unknown command.. ALthough I searched in Google and in the Wiki on dovecot, I did not find any hint - am I the first with this problem? TIA Ingo. -- Ingo Lantschner T (+43-1) 59 55 766 M (+43-664) 143 84 18 -- Ingo Lantschner T (+43-1) 59 55 766 M (+43-664) 143 84 18

"localhost" does resolve (I tried to ping it, and it worked), and 127.0.0.1 does not change anything. So I guess my initial guess was wrong, and Mail must be trying to see if the network is up before even trying to log in. Alan Schmitt

[Dovecot] .INBOX required?
by Todd Slater 19 Nov '04

19 Nov '04

Hi, Newbie to Dovecot and IMAP in general. The system in question is RH 9, Dovecot 0.99.11, Maildir, accessing mail with SquirrelMail, Thunderbird, Kmail, Mutt, Entourage and Mail.app. I've set up the maildir for users in ~/Maildir. Inside that I have other folders, .Sent, .Drafts, .Trash, .Junk, .MakeJunk, .MakeGood. ~/Maildir itself has the cur, new, and tmp folders, but I note that there is also an .INBOX folder. Mail to the account does end up in ~/Maildir/new and it's readable in the various MUA's (as Inbox). I'm just not certain why the .INBOX is there, and if I'm supposed to be creating the other folders as .INBOX.otherfolder. Thanks, Todd
