[Dovecot] Busy, again
by Timo Sirainen 24 May '06

24 May '06

Just a note to people if you're wondering why I'm not replying to most of my mails: I'm trying to get into university to start stydying cellular biology (so I'm applying to biochemistry and biotechnology). Their entrance exams are next wednesday, so I'm trying to use most of my time left to study for them (and also do some work..). I don't know much about the subject, so I really need to study for them. :) Then again, if I don't pass, my fallback plan is to go in via computer science and try again next year. Hopefully they allow taking the same bio-classes even if it's not my major.

[Dovecot] Two INBOX locations
by arilinux 24 May '06

24 May '06

Hello I'm running dovecot v1.0.beta3 on a fedora 4 machine. I have two kinds of clients: - first use IMAP and receive their mails (maildir) in /home/%u/mail - second use POP and receive their mails (mbox) in /var/mail/%u Problem is when I want to provide an access for second with squirrelmail which use IMAP, as the INBOX is in /var/mail/%u and IMAP settings tell that INBOX is in /home/%u/mail, they can't view their emails. Is there a way to tell to dovecot to search IMAP mails both in /home/%u/mail and in /var/mail/%u Thanks > Emmanuel RIZZI > ERILOG > 103 rue Beaupoil > 39210 DOMBLANS > Tel: 03 84 44 66 66 > Fax: 03 84 44 62 00 > > >

[Dovecot] Thunderbird 1.5 and messages with no Date: header
by grant beattie 24 May '06

24 May '06

hi, some of my Thunderbird users have a minor but annoying problem with messages that have no Date: header. these clients use BODY[HEADER.FIELDS (Date)] as the date for messages. when a message has no Date: header, they display the date as 01/01/1970 10:00:00 because Dovecot returns empty string. would it be possible for Dovecot to return INTERNALDATE instead, for messages that contain no Date: header? I know this is not *technically* correct, but it's a reasonable best-guess, and better than returning nothing. perhaps as a client-workaround? I vaguely recalled a previous message about this, but I couldn't find it today. grant.

[Dovecot] Shared folder (namespace) access hanging
by Jeff Turner 24 May '06

24 May '06

Hi, I'm using Dovecot 1.0-b8. We use a shared 'support' account for incoming support mail. For security reasons we want to instead have everyone with their own account, accessing a shared 'support' folder. So I've configured dovecot with a public 'Support' namespace: default_mail_env = maildir:/imap/mailboxes/%u namespace private { separator = / prefix = inbox = yes } namespace public { separator = / location = maildir:/imap/mailboxes/support:CONTROL=/imap/mailboxes/%u/shared-settings/support/control prefix = Support/ hidden = no } So now: - User 'support' logs in (this is the user whose folder is being shared). Dovecot creates a dovecot-uidlist file: root@redback:/imap/mailboxes/support/.INBOX.test# cat dovecot-uidlist 1 1147757548 9 1 1147755677.P8078Q3M183587.redback.sydney.atlassian.com:2,RSace 2 1147755677.P8078Q2M183587.redback.sydney.atlassian.com:2,abcdf 3 1147755677.P8078Q1M183587.redback.sydney.atlassian.com:2,Sabcd 4 1147756077.P8078Q8.redback.sydney.atlassian.com:2,Sabcd 5 1147756440.P8461Q3M643698.redback.sydney.atlassian.com:2,Sa 6 1147756440.P8461Q2M643698.redback.sydney.atlassian.com:2,Sa 7 1147756440.P8461Q1M643698.redback.sydney.atlassian.com:2,Sa 8 1147756440.P8461Q0M643698.redback.sydney.atlassian.com:2,Sa root@redback:/imap/mailboxes/support/.INBOX.test# ls -la total 60 drwxrwx--- 5 jturner mail 4096 May 16 15:32 . drwxrwxrwx 59 support mail 4096 May 16 15:31 .. drwxrwx--- 2 jturner mail 4096 May 16 15:18 cur -rw-rw-rw- 1 support mail 448 May 16 15:32 dovecot.index -rw-rw-rw- 1 support mail 21504 May 16 15:32 dovecot.index.cache -rw-rw-rw- 1 support mail 512 May 16 15:32 dovecot.index.log -rw------- 1 support mail 72 May 16 15:28 dovecot-keywords -rw-rw-rw- 1 jturner mail 0 May 16 14:52 dovecot-shared -rw-rw-rw- 1 support mail 516 May 16 15:32 dovecot-uidlist drwxrwx--- 2 jturner mail 4096 May 16 15:01 new drwxrwx--- 2 jturner mail 4096 May 16 15:14 tmp root@redback:/imap/mailboxes/support/.INBOX.test# - If I now log in as 'jturner' and subscribe to this folder, there appears to be nothing in the 'test' folder.

So I'm confused. Am I doing something stupid? Why is there a common .cache file (it doesn't get created in the CONTROL dir), but not a common dovecot-uidlists? Is anyone actually *using* shared folders? :) Thanks, Jeff

[Dovecot] IMAP Folder Creation
by Zach Hobbs 23 May '06

23 May '06

I am using Maildir with dovecot 0.99.14-1 and postfix. My IMAP server was working where I could create a folder in Kmail or Thunderbird and specify wether the folder was to hold messages or folders. Then something changed, and I lost all my folders that contained sub-folders. And now I cannot create folders that contain subfolders (Kmail doesn't event give the option anymore). I can create folders and put messages in them, but I cannot create subfolders in the newly created folders. The Maildir is owned by the user logging in. Do I need to do anything with permissions, or are there settings to allow/disallow this? I've been reading through everything I could find with dovecot and folders in the message, and I can't come up with anything. Here's an example file structure (logging in as "zta-tech_zach"): Maildir# ls -lA -R .: total 32 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:41 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:16 .customflags -rw------- 1 zta-tech_zach web1 52 2006-05-22 21:40 dovecot-uidlist drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:16 .INBOX drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 new -rw------- 1 zta-tech_zach web1 6 2006-05-22 21:41 .subscriptions drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 tmp drwx------ 5 zta-tech_zach web1 4096 2006-05-22 21:25 .Trash ./cur: total 20 -rw------- 1 zta-tech_zach web1 16591 2006-05-22 21:40 1148352021.3157_1.www.zta-tech.com:2,S ./.INBOX: total 24 -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:41 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:16 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:16 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:16 .imap.index.tree ./new: total 0 ./tmp: total 0 ./.Trash: total 40 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:25 .customflags -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:24 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:25 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:25 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:25 .imap.index.tree drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 new drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 tmp ./.Trash/cur: total 0 ./.Trash/new: total 0 ./.Trash/tmp: total 0 Thanks, Zach

[Dovecot] Dovecot IMAP not putting size in maildir filenames
by Bill Boebel 23 May '06

23 May '06

I notice that when you move a message from one maildir folder to another, Dovecot drops the size information ("S=") from the filename. Dovecot also does not add the size info to filenames after it gets it via stat(). Shouldn't Dovecot add the size info to the filename so that "maildirsize" recalculations are fast? Bill
