[Dovecot] Two strange behaviours with dovecot+postfix+squirrelmail
by Francisco Neira 20 Sep '05

20 Sep '05

Hi all, About a week ago I was forced to migrate my main (production) email server from RH9 to Centos4.1. The installation has dovecot-0.99.11 + postfix-2.1.5 and >600 mbox accessed email accounts. Number 1. Some users accessing thru squirremail (installed in my webserver) can read their INBOX at /var/spool/mail directory but when trying to delete a message they receive the following error message from squirrelmail: ERROR: Could not complete request. Consulta: COPY 1279 "mail/Trash" Reason Given: Internal error occured. Error report written to server log. [2005-09-16 15:08:04] and the error logged is the following: Sep 16 15:09:27 mail imap(username): mkdir_parents(/home/username//mail/.imap/Trash) failed: Permission denied I never stated that .imap/Trash when configuring dovecot and the strangest thing is that my account, as most of others, can delete messages moving from /var/spool/mail/my_name to /home/my_name/mail/Trash Number 2. Randomly, some users connecting from Mozilla Thunderbird via IMAP get an error message telling that there has been an error connecting to INBOX. Watching the maillog I found the following: Sep 16 13:07:43 mail imap(otheruser): File isn't in mbox format: /var/spool/mail/otheruser I accessed the user's inbox file with vi and found that there was a "--604" at the beginning of the file. In other case I found that the file was beginning with a truncated email message. Trying to "walk on the safer side", I changed the mbox_lock setting from "fcntl" to "dotlock" in the /etc/dovecot.conf file. Any suggestions and comments about his will be highly appreciated. Forgive me about my English, it is not my native lanaguage. Regards, -- Francisco Neira B. Administrador de Red Defensoria del Pueblo Lima, Peru, -05:00 UTC

[Dovecot] NO: Unsupported authentication mechanism
by Steve [Dovecot] 19 Sep '05

19 Sep '05

I'm happily using dovecot as my IMAP server and accessing mails using Thunderbird... but I want to use the Net::IMAP facilities in the Ruby standard library to write some scripts to automate various spam-related tasks & housekeeping. My Ruby script: require "net/imap" imap = Net::IMAP.new('localhost') imap.authenticate('LOGIN','myuser','mypassword') # More stuff using imap... From the documentation LOGIN uses plaintext authentication - which I understand is always acceptable for Dovecot when connecting from localhost. On the 3rd line I get a "NO response" exception raised (indicating that the IMAP server replied "NO") and the error message "Net::IMAP::NoResponseError: Unsupported authentication mechanism" If I change 'LOGIN' to 'CRAM-MD5' (the other value supported by Net::IMAP) then I get a similar (but not identical) error: "Net::IMAP::NoResponseError: Authentication failed: Unsupported authentication mechanism" If I use anything other than either 'LOGIN' or 'CRAM-MD5' I get an error from the Net::IMAP library saying "Unknown auth type" - which is reasonable. N.B. I've tried both where 'myuser' and 'mypassword' are valid - and not... this doesn't affect the error messages. There doesn't seem to be anything of interest in /var/log/messages... Can anyone tell me what is going wrong, and how to resolve this?

[Dovecot] FreeBSD port
by David King 19 Sep '05

19 Sep '05

FreeBSD users: I notice that the version of Dovecot in the FreeBSD ports system is back at .99. Are there any objections to my submitting an update to the FreeBSD ports for version 1.0a? Is it better to wait for 1.0 to be progressed a little or is it considered to be ready? 1.0a compiles and seems to run fine (on 5.3), so are there any obvious patches that would be needed for the FreeBSD build? -- Don't forget that 19 September is National Talk-Like-A-Pirate Day! http://www.talklikeapirate.com/piratehome.html

Let me know if you need further analysis of the cores. Jeff Earickson Colby College

[Dovecot] Very minor feature request
by Steffen Kaiser 19 Sep '05

19 Sep '05

Hello, I'd suggest a way to get to know the "capabilities" of a compiled Dovecot. The background is that I've run the sequence ./configure --with-ldap && make && make install twice, all three commands tell me that all is fine (ldap is listed in the modules), but still dovecot told me that ldap is no Usedb module. A "make clean" before solved the problem -- well, something one should anyway. Besides, the "dovecot --capabilities" should also list all the defaults. Bye, -- Steffen Kaiser

i currently use procmail to sort my different mailing lists into differnet files for sanity puproses is there a way dovecot can find all these files? i have default_mail_env set to mbox:~/Mail/ could i use *:~/Mail/ as every file in /Mail is a mail file? -- David Willoughby email: dlw(a)d1w.org icq: 1852393

Re: [Dovecot] Misbehavior with Dovecot and Mulberry
by Jon Roma 18 Sep '05

Well, ironically after my tests succeeded, my reply to the Dovecot list just now failed to append to the Dovecot maildir folder. So I guess it works sometimes and not other times. :( The error message is the same "failed: Invalid argument".

[Dovecot] "racing" error ???
by Andy Cravens 18 Sep '05

18 Sep '05

Anybody know what this racing error means? I've got hundreds of them in my Dovecot log file. I tried to search the archives but couldn't find a search link. Nothing on Google search either. dovecot: Aug 30 16:55:54 Error: IMAP(testuser): maildir_file_do(/export/home/testuser/mail) racing -- Andy Cravens

[Dovecot] Newbie question
by Andrés Rusconi 18 Sep '05

18 Sep '05

Hi, my name is Andrés Rusconi, from Tucumán, Argentina. Sorry my English, please. I am a very happy new user of Dovecot: I gained speed and simplicity with him. But I noticed that in clients who use Outlook, the deleted messages do not copy to the trash folder. This is not critical, but did not happen with Courier, and the users askme about this behavior. If some of you has somehow solved this small question, I will thank for their commentary. Saludos Andrés
