[Dovecot] No 'from' in messages
by Remy Zandwijk 06 Mar '05

06 Mar '05

Hi all, Over the weekend, we've migrated our old mail environment to Sendmail and Dovecot: - Dovecot 1.0 stable - Sendmail 8.13.3 - Procmail 3.22 Procmail is MDA for Sendmail and it delivers mail to Maildir boxes. Email clients like Eudora, Thunderbird, Outlook and mutt are working OK. When using Outlook Express and Pine however, in the message list the 'from' or 'sender' field is empty. This means users of these programs cannot see who did send the mail to them. When running Dovecot 0.99 in a early test period, this problem did not occur. Question: Did anyone see this behaviour before and how to fix it? Best regards, Remy Zandwijk

[Dovecot] Dovecot 1.0-stable .deb file?
by Ian R. Justman 06 Mar '05

06 Mar '05

Hi, all. I know that there's no official Dovecot 1.0-stable .deb, given Timo's recommendations. However, does anyone have even an "unofficial" deb of it for, say, Sarge? I want to use 1.0's ability to use both mbox and maildir; the latter is very helpful for dealing with mailing lists. Thanks in advance for any help. --Ian.

[Dovecot] Password scheme overides
by Andrew Hutchings 06 Mar '05

06 Mar '05

I notice in the wiki you can have password sceme overides (such as {PLAIN}password). Would this work with the password fields in SQL databases (as it isn't clear in the wiki or conf file)? Regards Andrew -- Andrew Hutchings Linux Guru Netserve Consultants Ltd. http://www.domaincity.co.uk/

[Dovecot] dovecot-pgsql.conf can't find in chroot? (debian)
by Matthew J. Harmon 06 Mar '05

06 Mar '05

In my original email I noted that the directory /usr/local/etc was in the dovecot.conf variable valid_chroot_dirs : valid_chroot_dirs = /usr/local/etc:/etc:/var/mail:/lib Is that not sufficient? Under the /var/run/dovecot directory the directories ./usr/local/etc exist with dovecot-pgsql.conf in. Is there some big RTFM item I'm missing here? -Matthew P.S. - email address changed due to problems with upstream, will jump back as soon as this is fixed so I can finish my migration :) On Sat, 2005-03-05 at 09:06 +0100, Gunter Ohrner wrote: > Am Samstag, 5.

[Dovecot] Still having problems deleting messages through IMAP
by Doug Eubanks 05 Mar '05

05 Mar '05

Hello, I am using SquirrelMail with the 1.0 releases, and I have even backed up to the latest stable release based on 1.0. I am using MailDirs. When I delete a message, the message still shows up in the message list until either I log out and back in or a new message arrives in that folder. Any ideas? Thanks Doug Eubanks doug(a)simflex.com The speed of time is one-second per second.

[Dovecot] mbox or maildir?
by Brian Read 04 Mar '05

04 Mar '05

I am using dovecot in an SMEServer (aka e-smith), and recently backed-up on one system and restored on another system the imap email directories. The trouble was that dovecot "guessed" the mail type wrongly, and I ended up with "empty" ~/Mail directories (did it create or populate these?), and full, but ignored ~/Maildir directories for every user. Could someone point me to the chapter and verse of how (and when) dovecot decides which type of mail is in use, and how you can change the decision. I tried editing /etc/dovecot.conf, but that didn't seem to make any difference. Using dovecot 0.99-10 under a Redhat 7.3 base on kernel 2.4.20-18.7 -- Cheers Brian http://www.abandonmicrosoft.co.uk

[Dovecot] Dovecot response to "FETCH" command
by Alex Tang 04 Mar '05

04 Mar '05

Hi folks. I just converted my site from UW+mbox to dovecot+maildir (stable-test59, 2005/02/25). For the most part, everything is great. The server seems faster and less memory intense than the UW server (this part has made me very happy). And it's definitely more user friendly to me than Courier. There is one thing however... A few of my users are using the web based mail reader (Squirrelmail-1.2.11) that i provide for them. Once i converted to dovecot, the squirrelmail users were reporting that when viewing the folder list page, 2 things were happening: * The date for all of the messages was being displayed as "Sun 4:00 pm" * all messages were shown as being "new". they never would be transferred into the "Seen" state. After doing some IMAP protocol sniffing, i found this difference in the way that the UW server and the dovecot server handles the "FETCH" command... Squirrelmail issues a FETCH command to get message header information like this (lines broken with backslashes for readability): A009 FETCH 1:1 (FLAGS RFC822.SIZE INTERNALDATE BODY.PEEK \ [HEADER.FIELDS (Date To From Cc Subject X-Priority \ Content-Type)]) The UW server returns: * 1 FETCH (FLAGS () RFC822.SIZE 710 \ INTERNALDATE "27-Feb-2005 23:50:42 -0800" \ BODY[HEADER.FIELDS ("DATE" "TO" "FROM" "CC" "SUBJECT" \ "X-PRIORITY" "CONTENT-TYPE")] {153} Date: Sun, 27 Feb 2005 23:50:42 -0800 From: root <root(a)scorchedearth.us.proofpoint.com> To: altitude(a)scorchedearth.us.proofpoint.com Subject: asdf When the same FETCH response is returned by dovecot, the response looks like this: FLAGS () RFC822.SIZE 3358 INTERNALDATE "27-Feb-2005 07:55:27 -0800") * 1 FETCH (BODY[HEADER.FIELDS (DATE TO FROM CC SUBJECT X-PRIORITY CONTENT-TYPE)] {205} Date: Mon, 28 Feb 2005 00:04:22 +0800 From: xxx xxx <xxx(a)xxx.com> To: dovecot(a)dovecot.org Content-Type: text/plain; charset=UTF-8; format=flowed Subject: [Dovecot] "not listening" notification I noticed that in the UW response, the "* 1 FETCH ..." is the first line, and contains all of the data except for the message header info. However, in the dovecot response, the data is split into 2 lines, and the first line is not the "* 1 FETCH" line. In reading through the squirrelmail source, squirrelmail is not recognizing this as a valid response, and thus the date, size, and flags are not being properly set in the internal squirrelmail message objects. This explains why both the date as well as the "seen" status of the message is never properly set. OK, after all this blabbing on...here's my question. Is the data being sent back by dovecot a valid response? My knowledge of the IMAP protocol is weak to say the least. I tried reading the IMAP RFC (3501), in particular section 6.4.5 which defines the FETCH command), and the RFC seems to specify that the response should have the "* # FETCH" lines come first. However, the RFC seems vague, and i didn't wade through any of the other RFCs out there. I figure it is legal, since the two other clients i've used seem to understand it just fine (thunderbird/mozilla, mutt). However, could this be the reason why mozilla/thunderbird sometimes gets the message size wrong (and hence why the "tb-negative-fetch" workaround is needed). For now, i'll bang on squirrelmail to support the response sent by dovecot. Thanks. ...alex...
