Tim, Thanks for the reply. I did check the maillog quite a bit. Fortunately, I had kept an orig of the dovecot.conf file so I rolled back to the example I found on the dovecot.org website and now it's up and running. It's all smoke and mirrors to me, mostly, but at least it's working for now. I'll come back to this question of implementing TLS or SSL later, in my voluminous spare time. It appears to be a very powerful program and should carry me through to the next millenium...

[Dovecot] Just installed with Fedora 2
by Michael J. Pawlowsky 26 Aug '04

26 Aug '04

I just upgraded my RH9 installation to Fedora 2. To my surprise, imapd seems to be gone from the core. I noticed there are now two IMAP servers docevot and cyrus. After reading brief descriptions of both, dovecot would seem to be more compatible with my setup. Especially since I'm using mbox's. I have 2 questions. It seems like dovecot does not support mailboxes inside of a directories. Am I right in thinking this? Second I get the error message: The current command did not succeed. The mail server responded: Error in IMAP command MYRIGHTS: Unknown command. My client is Thunderbird. Any work around for this? Thanks, Mike

[Dovecot] 0.99.10.x auth memory leak?
by Christian Balzer 26 Aug '04

26 Aug '04

Hello, running 0.99.10.6 (but seen it before that, too). Also (quite obviously) running 5 auth processes, given the fact that this is a pretty busy box and I didn't want to introduce any artificial bottlenecks. Alas with them eating up half of the free memory (which would go to a much better use as FS cache) I'm getting sorta concerned. If it's not a leak, it's caching something rather needlessly and inefficiently (the LDAP DB memory footprint for ALL users is less than this and the box below just serves half of those). This box sees about 0.5 million POP3/IMAP logins/day. --- PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 31235 root 16 0 220m 216m 5560 S 0.0 10.7 25:01.54 dovecot-auth 31234 root 16 0 205m 202m 5560 S 0.0 10.0 24:08.84 dovecot-auth 31231 root 16 0 200m 196m 5560 S 0.7 9.7 23:25.37 dovecot-auth 31232 root 16 0 196m 192m 5560 S 0.0 9.5 23:10.44 dovecot-auth 31233 root 15 0 179m 175m 5560 S 0.3 8.6 22:13.07 dovecot-auth --- So, I guess my questions to Timo are: Think it's leaky and any idea where?

[Dovecot] [PATCH] pass struct io * to io_loop_handle_add()/io_loop_handle_remove()
by Andrey Panin 25 Aug '04

25 Aug '04

Hello, currently I'm working on new ioloop handler which uses epoll(4) API introduced in Linux kernel 2.6. In this API each fd added to fd set by epoll_ctl system call can be accompanied with user supplied data (integer or void pointer). epoll_wait syscall reports arrived events as an array of structures containing event mask and user data. Attached patch replaces fd and condition parameters passed to io_loop_handle_add() with struct io pointer. Now io_loop_handle_add() can pass this pointer as user data to epoll_ctl syscall and when event arrives we will have corresponding io structure pointer for free withiot traversing possibly long ioloop->ios list. Please take a look. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

I guess ssl_ca_file is newer than 0.99. I have the same settings (debian -sarge) and i am using ssl_cert_file and ssl_key_file to get the certificate working. I checked ssl_ca_file and i got the same error, nevertheless it's in the recent dovecot.conf file from 1.x.testing, therefore it should be newer than 0.99.

Adding ssl_ca_file to my configuration produces "Unknown setting: ssl_ca_file" on dovecot startup. Postfix has a smtpd_tls_CAfile argument and that part is working fine.

[Dovecot] Newbie: dovecot not running.
by Simon Waters 23 Aug '04

23 Aug '04

Okay, sure it must be trivial.... I have old Redhat box, want a quick and dirty IMAP server, thought good time to try out dovecot (I'd rather it had Debian on too ;). Downloaded and compiled from source - no options to configure. Auth data is in /etc/passwd and /etc/shadow (as well as NIS). vi /usr/local/etc/dovecot.conf as expected. Disable ssl in conf. Basically email is in mbox format in /var/spool/mail/%u Should go somewhere ~%u/mail is fine, as would be ~%u/Mail (I don't care at the moment). created a user "dovecot..." to run as and edited conf file. If I run /usr/local/sbin/dovecot it terminates without errors, the fork is completing I think, and the main program returns as expect. Running imap-auth from xinetd gets me a greeting banner, but then the connection is closed. Trying to run "imap" directly just dies in a blizarrd of "dot locking" errors and the like, where it seems to ignore the locking directives (should I set an env or some such?), but I think that it is basically running (it creates indexes in ~/mail/...mumble) but complains about the dotlocking, and then spews an internal error (which it claims is logged to server log?). I'm off to try auth_verbose, but any tips or hints appreciated. I'm assuming /usr/local/sbin/dovecot is what was called "master" given it is in the master src directory. Simon

[Dovecot] 1.0-test33
by Timo Sirainen 23 Aug '04

23 Aug '04

http://dovecot.org/test/ I think I found and fixed the last bug that was giving me problems. Now that Dovecot has been successfully working for a few hours, time for a new test release :) This release has major changes, so there might still be some bugs left. Be careful. If you're upgrading from previous 1.0-test release, you must delete all existing dovecot.index.log files or you will get errors. So, the changes are: - All network sockets are nonblocking now and all the waiting is done in a single event loop. This required tons of changes all over the code. - Transaction log file doesn't use locks for reading anymore - Some mbox fixes - search text was broken

Client should never see any "real" error messages to make sure no extra information about the system gets leaked. So any time something unexpected happens, Dovecot gives the "internal error" message to user while writing the real error to log file. The timestamp is there to help sysadmin find the real error message from log files when user gives a copy&pasted internal error message. Instead of timestamp I guess there could be also some unique identifier which could be grepped from logs but I think timestamp is better. And about the original problem of giving "internal error" when Dovecot process didn't have access to some maildir.. Maybe it could have replied "Permission denied" to client in that case. It already does in several cases, but I guess the problem here was that it was trying to create the missing dirs but couldn't. I'll look over all these permission issues properly when creating real shared folder support.

Did Dovecot actually crash? Did it log a more sensible error message to syslog? I think Dovecot quite often reports an "internal error" to the client but then writes a more sensible error message to syslog. Which is probably no bad thing as you may well not want clients to see detailed error messages - there's nothing they can do about it anyway. Andrew

[Dovecot] Multiple dovecot processes stepping on each other

If you try again immediatly, it works. If I do a `ps -p 21082` I can see the process (dovecot-auth). This does not happen when I have only one dovecot process running.

[Dovecot] What about saving your INBOX at ~/mbox ?
by Nico Kadel-Garcia 23 Aug '04

23 Aug '04

Hi, folks. I'm testing out RedHat's "Fedora Core 2" release, which has switched from the old WashU imapd to dovecot-0.99.10. Overall, this looks like a really, really good move on their part: it looks like a very sweet little tool without some of the ingrained idiocy of Mark Crispin insisting that every home directory consist of nothing but mbox files and allowing you to use a configurable subdirectory by default, ~/mail. Cool. There is one feature of the old WashU imapd that I miss, though. That daemonn could be configured to automatically transfer the user's email to the "~/mbox" upon activation of the daemon, effectively reducing the size of the /var/spool/mail/{username}" mail spool and helping keep the user's disk usage in their home directories, not in /var/spool/mail. This can be a good thing for various reasons. But I don't see any way to enable that behavior for dovecot. Is there something I'm missing, or do folks feel it would be reasonable to add? -- Nico Kadel-Garcia Systems Engineer Mitsubish Electric Research Lab <nkadel(a)merl.com>

I thought that Dovecot was supposed to handle that kind of thing? Reading from the website: "Any kind of crash is considered as bug and will be fixed - even if it happens only by deliberately poking the index files." I've done it in the past by just creating the bare folders - they appear in the IMAP folder list then when they're used Dovecot seems to create the sub folders anyway. The issue I'm asking about here is, should the error message say "Internal Error [date time]" rather than something useful?
