I am using dovecot-0.99.10.5-1 which was on the development tree of Fedora. Though I would think the one that came stock with Fedora 2 should work as well. I have no reason to think it won't. One note. I don't use POP that much. I have one person who uses it and they haven't complained. > So if all the mail is moved to Maildir (thus eliminating the typical > mailspool), and somebody pop's onto the server, Dovecot will use the > Maildir/Inbox for the pop? Yes it will. If you read the mail-storages.txt documentation file it talks about it. I would read the section on "Detecting what to use". I did NOT set the default_mail_env variable in my /etc/dovecot.conf and it figured it out automagically :) Good luck, John

[Dovecot] 0.99.10.5 imap flag update issues
by Hauke Fath 03 Jun '04

03 Jun '04

Hi, there is an issue left in 0.99.10.5 which (I think) is a problem with imap status flags. It shows up in two places: (1) When new mail is delivered to the inbox, the last read mail changes to "unread". (2) When you move mails from the inbox to another folder with Mozilla (1.6 on win32, Linux, NetBSD), they are not removed from the inbox, effectively performing a copy instead of a move. And, while I am at it, (3) I see a regular log entry from a MS Outlook 2000 SP 3 Jun 3 10:26:23 bounce imap-login: SSL_read() syscall failed: EOF [130.83.XXX.XXX] The setup here: OS NetBSD 2.0beta, MTA sendmail 8.12.11, LDA maildrop 1.3.9, dovecot 0.99.10.5, OpenSSL 0.9.7d Any ideas? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281 / \ Respect for open standards

[Dovecot] Getting POP3 up and running
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! Now that I happily smiling have Squirrelmail working on the new setup (Fedora Core 2), the next hurdle seems to be getting POP3 to work. According to my understanding of the documentation I changed the protocols line in dovecot.conf to: #protocols = imap imaps pop3 pop3s then restarted dovecot, but still can't connect to pop3 (not even after rebooting the whole system). Doing an nmap on my server does not show port 110 as open. Any clues as to what I may be overlooking? Thanks for your support, Antonio There is a world of difference between searching for happiness and choosing to be happy!

My suggestion would be to use Dovecot as your POP and IMAP server. And convert everything to use Maildir unless there is some special reason you want to keep mbox format for.

[Dovecot] Loggin error with Squirrelmail on Fedore Core 2
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! I am switching a mail server setup to a new machine which has RHL Fedore Core 2 installed, which uses Dovecot. I managed to get Squirrelmail to work on my personal account, but when logging in with some other accounts I get the following error as response: ERROR : Connection dropped by imap-server. Query: Capability I did a web search on this and found a message from Tim Middleton who experienced the same problem. He also suggests a workaround: "I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions." I would like to try this, but I am still fairly new to Unix. Could anyone show me how to set up such a chron job? Are there other, manual, ways to touch the mailboxes? Thanks, Antonio Nunes Don't let who you can be keep you from being who you already are.

[Dovecot] Supporting POP & IMAP with Sendmail
by John Duino 03 Jun '04

03 Jun '04

Greetings! I dug thru the archives but didn't see a clear answer to this. A client has an existing sendmail/pop3 system, and I would like to switch to dovecot for imap support. For imap I much prefer the Maildir format over mbox, however, sendmail natively dumps to mbox (mailspool) and that is what pop typically reads. I've read the threads on how to make sendmail write to Maildir. My problem is that I'd like to support both pop/mailspool and imap/maildir. While running dovecot in imap-only it will use mbox format to read the /var/mail/user as the Inbox and then create the full imap structure under ~user/mail but in mbox format, not maildir. If/when I turn on both pop and imap in dovecot will it allow this with the current config? Or will I still need to convert sendmail output to maildir...and then I assume dovecot/pop will read from ~user/Maildir/Inbox even though it is in Maildir format? Basically, if I'd prefer to not have to convert sendmail to Maildir format, have dovecot always treat /var/mail/user as the Inbox for both pop and imap, and for those who switch to imap, have it store their other folders in ~user/Maildir. Asking too much? Thanks! John

Fairly easy on the small system I had.

Timo says that it is NOT available in the version that comes with Fedora Core 2. It will be available in the 1.0 series by defining multiple namespaces. The current 1.0-tests allow this. > What would I have to change for Sendmail to make it use > Maildir for the Inbox? Sendmail does NOT need to be changed. > Can procmail support Maildir? Yes and that is what you need to change. I setup /etc/procmailrc to have the line: DEFAULT=$HOME/Maildir/ Make sure there is the terminating / on that line. What this will do is make all new mail that is delivered via procmail go to each user's Maildir folder. But what you need to do first is convert your existing mbox mail into maildir format. I used the program that was recommended to me: mb2md http://batleth.sapienti-sat.org/projects/mb2md/ This program worked great to convert my /var/spool/mail/user_name stuff and also folders that I had created under ~/mail/ So now my whole system is using Maildir format.

[Dovecot] dovecot and virtual hosting
by Vegard Svanberg 03 Jun '04

03 Jun '04

Hi. A usual hosting provider setup depends on having one IP ("virtual mailserver") per domain. Using dovecot on servers handling hundreds or thousands of domains today equals to having multiple instances of dovecot running. This problem could be solved by making dovecot take into account the IP address the user connects to and authenticate against the proper {database, table, pw-file, [...]} based on that.

[Dovecot] Serve list archives by dovecot IMAP
by Kenneth Porter 02 Jun '04

02 Jun '04

Has anyone considered setting up a Dovecot public server to serve the list archives by IMAP? Or does Dovecot not do anonymous read-only access? (I note by comparison that the Cyrusoft Mulberry list archives are served by an IMAP server. <http://www.cyrusoft.com/mulberry/support/anonimap.html>) It should be sufficient to set up Dovecot on some server in the dovecot.org domain and subscribe it to the lists.

[Dovecot] Dovecot + SSL + Fedora
by David Keegel 02 Jun '04

02 Jun '04

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at: http://www.dovecot.org/list/dovecot/2004-May/003316.html with the patch that just ignores the return code of RAND_bytes(). Would disabling SSL in dovecot.conf also be a reasonable way of avoiding the problem of dovecot crashing? My plan is to set ssl_disable = yes and also take out pops and imaps from protocols. That is a lot easier for me than getting source, patching it, re-compiling and re-installing.

[Dovecot] Postfix SASL AUTH from Dovecot
by Timo Sirainen 02 Jun '04

02 Jun '04

Again today got annoyed at Cyrus SASL. Upgrading it to newer version had broken PAM support. Trying to login as "user@domain" resulted it only asking for "user" from PAM. Well, got it patched and working again, but I'd rather not go through it all the time.. So I finally did what I had been thinking about a year or so, change Postfix to use dovecot-auth directly. This required cleaning dovecot-auth quite a lot, but it seems to be working now. Actually I finally implemented support for initial SASL response as well. POP3's AUTH command had required support for it, strange that no-one ever complained about it not working. If you want to try it, you need very latest CVS version of Dovecot and this patch for Postfix: http://dovecot.org/patches/postfix-dovecot-auth.patch dovecot-auth can be run on it's own (configuration in environment variables), or you can use extra_sockets auth setting which is a ':' separated list of UNIX sockets where to listen in. You'd probably want to set it to /var/spool/postfix/etc/dovecot-auth, the location is hardcoded to /etc/dovecot-auth in the patch for now (smtpd is chrooted). The only real problem is that Dovecot creates the dovecot-auth socket using 0660 root:root modes, so you have to manually chmod it to 0666 or fix owner/group. I guess that needs some more thinking.. Probably each socket should have separate settings for it, but how to do it easily in configuration? .. The patch has also hardcoded dovecot path in Makefile.in, you'll need to change that.

Aloha. The current CVS snapshot and 1.0-test14 will not build on Solaris 8 because it does not provide a sendfile() funtion. It just has sendfilev(). Solaris 9 has sendfile(), though. Using the old sendfile-util.c from 1.0-test1 and setting HAVE_SOLARIS_SENDFILEV instead of HAVE_LINUX_SENDFILE in config.h works. Greetings, Andy.

[Dovecot] Small change to make dovecot pop3 uw-imap migration friendly
by Oleg I. Vdovikin 01 Jun '04

01 Jun '04

Hi, today I've finished migration from uw-imap daemons to shiny and fast dovecot. With thanks of dovecot my mail server load average drops by factor of ten even with ancient unix mailboxes. ;-) So, the only thing I've discovered is what POP3 uidls are different than ones used in the uw-imap. Luckily, the difference are only in the format string used in uidl response. So, I've made the following change in the code --- dovecot-0.99.10.4.orig/src/pop3/commands.c 2003-05-28 15:17:15.000000000 +0400 +++ dovecot-0.99.10.4/src/pop3/commands.c 2004-05-27 14:06:48.000000000 +0400 @@ -374,7 +374,7 @@ while ((mail = client->mailbox->fetch_next(ctx)) != NULL) { client_send_line(client, message == 0 ? - "%u %u.%u" : "+OK %u %u.%u", + "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, client->uidvalidity, mail->uid); found = TRUE; } and got everything just like in the old uw-imap pop3. I'm current running RH9, but thinking of FC2 which uses dovecot. So, I've rebuild the FC2 rpm for RH9 including this patch. Pop3 users, which do not remove their mails from the server are really happy - they do not receive old mails twice. Probably this small change could be applied to the 1.0, or used as a config option. Any suggestions are greatly appriciated. Thanks, Oleg.

[Dovecot] 1.0-test14
by Timo Sirainen 31 May '04

31 May '04

http://dovecot.org/test/ Maildir syncing is still somewhat broken. I can't really figure out what the problem is. Maybe it's in indexes after all which are just causing bugs in syncing. I think I'll finish implementing mbox syncing and see if same problems appear with it. This release has mostly dovecot-auth changes: - Delay reporting failed authentications - Log IP address of failed authentications (if verbose = yes) - Password schemes can now be loaded from plugins. Example: http://dovecot.org/patches/1.0/password-scheme-lmpass.c - (now that I think of it, auth mechanisms could be implemented as plugins as well if they were placed in password-scheme directory, I think I'll change the directory name so it's more logical) - SASL initial responses are supported (POP3) - SHA/SHA1 password scheme implemented with OpenSSL - dovecot-auth can run as standalone process now (but that doesn't work with Dovecot itself at least yet) - Changes to make it more easier to use it outside Dovecot (eg. the Postfix patch) Added new variables which can be used: %l - local IP address %r - remote IP address %P - PID Added mail_log_prefix setting where variables can be used. So if you want eg. "imap(user,ip-addr,pid): ", set it to "%p(%u,%r,%P): ". And others: - added maildir_stat_dirs setting - several bugfixes for indexes

[Dovecot] Dovecot returns everything starting with "." as folder
by Christoph Hohmann 30 May '04

30 May '04

Hi, I'm using dovecot imapd 0.99.10.5 from debian unstable and I noticed that dovecot returns everything in the maildir folder that starts with a "." as a folder as the result of LIST "" "%" command without checking if it is really a maildir folder (must contain the directories cur, new, tmp and the file maildirfolder). This is a little bit annoying because it also returns Sylpheed's cache files '.sylpheed_cache' and '.sylpheed_mark' if they exist in the maildir. -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/
