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.

OK, last try. Is it supposed to give the current time and date in the error message. I've no problem with it giving an "internal error" message to the client, but I am a little confused about the time being in there. That's all I'm asking about.

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
by Peter Hessler 23 Aug '04

23 Aug '04

I have two instances of dovecot running, one for v6 and one for v4 connections. The only differences in the config files are: --- /etc/dovecot-ip6.conf Wed Aug 18 11:15:43 2004 +++ /etc/dovecot-ip4.conf Wed Aug 18 11:09:17 2004 @@ -10,7 +10,7 @@ # *** NOTE *** Some values HAVE been changed for OpenBSD use. # Base directory where to store runtime data. -base_dir = /var/dovecot-v6/ +base_dir = /var/dovecot-v4/ # Protocols we want to be serving: # imap imaps pop3 pop3s @@ -23,7 +23,7 @@ # "host:port", although with multiple protocols you probably want to move # this setting inside protocol imap/pop3 { ... } section, so you can # specify different ports for IMAP/POP3. -listen = [::] +listen = * # IP or host address where to listen in for SSL connections. Defaults # to above if not specified. For the most part it is working, but every so often, the auth freaks out for one (random) account. The error for one example is below: Aug 18 11:13:12 gir dovecot: login: Authentication process 21082 doesn't exist Aug 18 11:13:12 gir dovecot: pop3-login: Internal login failure: phessler [208.201.244.164] This happens on both v4 and v6 connections, but infrequently. 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. What is the best way to have multiple dovecot processes without them stepping on each others toes? This is on OpenBSD/macppc -current, running dovecot-1.0-test32. -- Mosher's Law of Software Engineering: Don't worry if it doesn't work right. If everything did, you'd be out of a job.

[Dovecot] Dovecot stop accepting command When reading disk quota (soft)
by Chan Min Wai 23 Aug '04

23 Aug '04

Hello all, I've face some problem here and I think it should be the way. 1) I'm running Dovecot version 0.99.10.4 (fc1 release) on RH9 2) One of the users have reach the soft disk quota limits 3) Dovecot stop the users from deleting email. What I think was, dovecot should let the user continue to use the services until it reach the hard limits, but pop up message each and every time ;). Anyone have that problem before? Thank You Chan Min Wai

[Dovecot] Sent, Drafts, Trash folders
by Jason M. Wilde 23 Aug '04

23 Aug '04

I am hosting imap mail for a new affiliate and am offering webmail via squirrelmail as well. Squirrelmail created INBOX.Sent, INBOX.Trash, etc by default and I would like to use these folders for my Dovecot imap users. I am using the mbox format, Postfix and users retrieve mail via the Outlook client remotely in addition to webmail access. Thank you for any help. Jason

[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>

[Dovecot] Is 1.0-test stabilising?
by Curtis Maloney 23 Aug '04

23 Aug '04

Has Timo backed off work, and been busy with something else, or has 1.0 really stabilised that much? Seems to me just a couple of weeks ago we were seeing a new test release every few days... now there's been nothing all month... I'm hoping it's ready for release... but if it's just that Timo's busy, well, I can understand that. We're about to receive some new servers, and I hope to migrate from 0.99 to 1.0 as we migrate to the new machines. -- Curtis Maloney

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?

[Dovecot] Unusual behaviour
by Mark Lidstone 20 Aug '04

20 Aug '04

Hi, I've just noticed something strange in dovecot 0.99.10.5. I created some IMAP folders from the command line (mkdir .INBOX.Folder1) as a different user to the owner of the mailbox. Obviously when I tried to view them via IMAP I got an error message, but the message to the client was "internal error[date time]" where date and time appeared to be the current date and time. Is this correct behaviour? Dovecot was running on FC2, and the client was Mozilla Thunderbird under Windows.

[Dovecot] Question: email system architecture
by Gland Vador 18 Aug '04

18 Aug '04

Hi, I have a question about how to implement a mail system, but I don't know where to ask. Until now, I have a mail system who receive mail by postfix and transport it through procmail to the /var/spool/mail/username mailbox. From here it is retrieved through dovecot (POP3). Now I have two more users, I want to implement a IMAP server, and also provide a webmail (squirrelmail) interface. And in order to filter spam, I want to install spamassassin. Until now it was thunderbird who made the filterring, but with a webmail interface it's no more possible. So suppose that I have configured procmail to deliver "good" mail in an Inbox folder and "spam" in a SPAM folder. This for each user mailbox. I also have configured dovecot as IMAP server and any IMAP client can see the two folder with spam and ham. And here comes my implementation problem. If a user see a "good" mail in his spam folder (or vice-versa) he will take this mail and move to his inbox folder. But, I want to be able to say to spamassassin to learn that this message is ham, with the command sa-learn, and also remove the x-spam* headers. And I don't see a good way to do that. In my opinion, it should be the MUA task, but spamassassin is server based. It's any way that dovecot when it moves the mail between tho folders can call an external script who will make this job in fonction of source/destination folder? Maybe it's a silly question (I don't know IMAP and his possibilities). In this case, can anyone explain (or point to) me a way to do that ? Sorry for this long message. Edd.
