This is from 1.1rc5.

Hello, I am trying to get LDA working in conjuction with Postfix, but whenever I activate Dovecot LDA in main.cf and send myself a test messsage, I get an error message in maillog: [...] May 8 20:47:17 venus postfix/pipe[36077]: 4022B5C38: to=<cb(a)lim.nl>, orig_to=<colin(a)lim.nl>, relay=dovecot, delay=0.02, delays=0.01/0/0/0.01, dsn=5.1.1, status=bounced (user unknown) [...] Postfix's virtual LDA has no such problem: [...] May 8 20:49:39 venus postfix/virtual[36181]: F3DF05C37: to=<cb(a)lim.nl>, relay=virtual, delay=0.05, delays=0.03/0/0/0.01, dsn=2.0.0, status=sent (delivered to maildir) May 8 20:49:39 venus postfix/qmgr[36091]: F3DF05C37: removed [...] Here is the LDA section in dovecot.conf: protocol lda { postmaster_address = postmaster(a)lim.nl mail_plugin_dir = /usr/local/lib/dovecot/lda mail_plugins = cmusieve log_path = /var/log/dovecot-deliver info_log_path = /var/log/dovecot-deliver auth_socket_path = /var/run/dovecot/auth-master } My maildirs are here: mail_location = maildir:/home/colin/vmail/%u and Dovecot IMAP has no problem retrieving messages from that location. What might be going wrong with delivery though? Thanks. -- Colin Brace Amsterdam http://lim.nl

[Dovecot] ipv6 woes

I'm trying to bring up dovecot on a dual stack machine. I tried search for the answers; the answers I found and tried failed :-(. If I try this: protocol imap { listen = 216.218.228.114:143, [2001:470:1:18::114]:143 ssl_listen = 216.218.228.114:993, [2001:470:1:18::114]:993 } (and similiar for pop3) I get: Fatal: listen: Can't resolve address 216.218.228.114:143, [2001:470:1:18::114]: hostname nor servname provided, or not known If I instead use: protocol imap { listen = *, [::] ssl_listen = *, [::] } I get this error: Fatal: listen: Invalid port in address This is while using dovecot 1.0.13 Build options: ioloop=kqueue notify=kqueue ipv6 openssl Any recommendations? -- Jason Fesler, email/jabber <jfesler(a)gigo.com> resume: http://jfesler.com "Give a man fire, and he'll be warm for a day; set a man on fire, and he'll be warm for the rest of his life."

[Dovecot] MBOX to Maildir preserving the UIDL (outlook-tested, no redownloading)
by Horn Wijaya 09 May '08

09 May '08

TESTED AND RUNNING, MIGRATING from MBOX to MAILDIR, PRESERVE UID and OUTLOOK sees the email as downloaded. I hope this helps a lot of people out there. Feel free to post this somewhere else too. By: Horn Wijaya (hwijaya(a)nodens.biz) 8th May 2008 I have been searching for weeks for a foolproof method to migrate all my users mbox to maildir/dovecot without having the pain of downloading all emails again, especially for heavy users. It would cause frustration to thousands of my users. So.... eventually I found out why Outlook will keep downloading the emails despite all the configuration done in the dovecot.conf. Apparently the UID is generated realtime. When it first generated, it took the time the process runs. Before I migrate, here's the email sample which I have downloaded to my outlook (and keep email on server), and then I use telnet to pop to get the uidl list. +OK POP3 localhost.localdomain v2003.83rh server ready user ***** +OK User name accepted, password please pass ***** +OK Mailbox open, 444 messages uidl +OK Unique-ID listing follows 1 47b1303d00004c2d 2 47b1303d00004c2e 3 47b1303d00004c2f ... 47b1303d = 1202794557 = 12 Feb 2008 13:35:57 the date and time the mbox was created 00004c2d = 19501 the IMAP counter so far.... sequently added as you could see with email #2 and email #3 Then I switch my POP server to dovecot, and migrate my MBOX to Maildir, and I do a telnet to get the UIDL +OK Dovecot ready. user ***** +OK pass ***** +OK Logged in. uidl +OK 1 4822815000000001 2 4822815000000002 3 4822815000000003 ... 48228150 = 1210220880 = NOW 00000001 = counter starts at 1 No wonder outlook sees the emails are NOT-DOWNLOADED-YET status. Then I ponder for another few days and the key is in the dovecot-uidlist...... How to fill it with the correct info.... and there's a way. Which I hope useful for converter developer, and could be implemented in the next version of the converter. Here's the step I do to reach my objective which is to get UID 47b1303d00004c2d in the first email: 1. mb2md-3.20.pl -s /var/mail/hwijaya -d home/hwijaya/Maildir/ that's converting 444 emails from mbox to 444 files in the Maildir/cur folder 2. cd /home/hwijaya/Maildir/cur 3. grep IMAPbase * and I get 1210219860.000000.mbox:2,S:X-IMAPbase: 1202794557 19944 The last 2 strings are the KEY to the ORIGINAL UID 4. So in order to prepare the environment to fool it, some calculations are needed: How do we get 19501 as the first counter? as expected in the first POP TEST above: 19944 - 444 emails + 1 = 19501 5. cd /home/hwijaya/Maildir 6. echo '3 V1202794557 N19501' > dovecot-uidlist 7. DONE....... pop it via outlook and nothing will be downloaded, after pop or imap is processed, the dovecot-uidlist is auto-filled, index auto generated. Proof: +OK Dovecot ready. user ***** +OK pass ***** +OK Logged in. uidl +OK 1 47b1303d00004c2d 2 47b1303d00004c2e 3 47b1303d00004c2f ... I assume the same method could be used for individual folders in the imap (under .mailboxlist or .subscriptions) Please do let us know if there's any cases/environment that it won't work. Thanks very much, and a big migration job is in front of me now... ------------------------------------------ Warmest Regards From: Horn Wijaya Consultant hwijaya(a)nodens.biz http://www.nodens.biz/ Nodens Solutions Pte Ltd "where there is freedom in your choice"

[Dovecot] [Q] IMAP update message header?
by Roderick A. Anderson 08 May '08

08 May '08

More about IMAP, less about Dovecot. This is more an IMAP question than specifically about Dovecot. Sorry to ask here but I've been researching, reading and lurking with no answer so far. What I'm doing is running reports as a user from a remote system to provide a list of messages (Sender/From, Subject, Date, size) in a specific folder(?). In one case it isn't even a Dovecot based server so I only have access as a client. (Though I use Dovecot on several other systems and will need this capability for them.) When a message in the folder has been reported I'd like to add a X-Header-??? indicating that the message has been reported so the next time through it isn't reported again. (After the message is X days old it is deleted.) These reports are run using Perl and I've tried most every CPAN module available but haven't figured out how to change/add a header then save the message back. So far I haven't been able to determine if this is even possible by reading the RFCs. Is there a method as a client from a remote system to make changes to a message then save it back? What is the IMAP verb, command, etc. to do this? Or if there are Perl programmers on the list a brief description (or code) for doing this? TIA (and sorry for the off topic posting), Rod --

This will allow you to test things and see if it works better. The changes will revert to the system pre-defines when you re-boot or restart. IIRC, there is a master setting (unchangeable without recompiling OS X) that will not allow you to go over 65536, but I may be mistaken about that. For a permanent change, add the following lines to the /etc/sysctl.conf file: or the /etc/sysctl-macosxserver.conf file for Mac OS X Server You may have to create the file, especially if you are the only user. (Make sure that only root has access to this file!!!!!!) kern.maxfiles=65536 # System-wide limit kern.maxfilesperproc=32768 # Per-process limit This Is ONLY For OS X 10.3 or later. For earlier versions you need to use /etc/rc which was so long ago that I do not recall all of the commands (sorry). HTH, Jerry

[Dovecot] How do I increase the fd limit on OS X?
by Rob Frohne 08 May '08

08 May '08

Hi All, I just upgraded to the new 1.1rc5 from 1.0 that I had been using and it advised me to increase the file descriptor limit. I'm not sure how to do this. There is a command built into tcsh that allows me to do this called limit, but sudo limit 4224 doesn't work, and usually dovecot is started from the rc.local file if I recall right, and I'm not sure how to set this up from there. Any advice. Thanks, Rob -- Rob Frohne <rob.frohne(a)wallawalla.edu> Walla Walla University

Not true! simple way: Just change the default config TB create your account from with the settings you need. You can find the file under your program dir i.e. C:\Programme\Mozilla Thunderbird\defaults\pref Compare the defaults to your working set of setting and change them accordingly. You can activate TLS or CRAM-MD5 and so an. You can also predefine LDAP servers etc. more elaborated way: Mozilla Mission Contol: -> http://developer.mozilla.org/en/docs/MCD,_Mission_Control_Desktop_AKA_AutoC… Hope it helps! Hans

[Dovecot] thunderbird sane config (OT)
by rosenfield.albert＠gmail.com 08 May '08

08 May '08

Does anyone have any experience putting together a sane config for Thunderbird in an automated fashion? Automated meaning "simple to distribute to users". -- (Background: I'm currently experiencing that Thunderbird does not work against Postfix/Dovecot because the wizard interface for setting up an account does not accept TLS-only servers. Users just sit there with a broken Thunderbird, not knowing what to do :-/.) (PS: Also, giving everybody a GMail-like threaded interface per default would be cool.) (PPS: If anything good comes up, I plan to put this in fx the Dovecot wiki.)
