[Dovecot] dovecot imap and thunderbird tags
by Lorenzo Bettini 02 Mar '09

02 Mar '09

We've been using an imap(s) dovecot server for a while on an ubuntu 8.04.2 and we noted that tags set by thunderbird ("important", "to do", etc.) are almost always lost, i.e., when connecting to the same imap account from another machine, the tags are not there anymore... this always happens for the Inbox, and seldomly for other imap folders... anyone else experiencing this? Note that the same problem does not arise with other imap server accounts... thanks in advance Lorenzo -- Lorenzo Bettini, PhD in Computer Science, DI, Univ.

[Dovecot] Maildir format use question
by Rick Romero 02 Mar '09

02 Mar '09

Hey all, I've got a couple servers using Maildir format. As I understand it from a simple perspective, 'new' contains newly delivered messages, and 'cur' contains messages that have been 'handled'. I like to keep things simple for users, so rather than have 'Spam', 'Junk' 'ToLearn' and other possibly confusing folders, what I thought I would do is scan their .Spam/cur folder for mail that was older than an hour (based on file atime(?) stamp) and feed that through SpamAssassin. The idea being that anything in 'cur' would: 1. have been moved there by the user. 2. be recently read, and I think if it were innocent, would be handled within an hour 3. Not contain newly delivered, unread mail. This is actually what I see when I view my Spam folder through Evolution. If I use a PHP webclient - either Horde or Roundcube (I've captured the debugs if you'd like them), then a simple view of the Spam folder causes the files to be moved from new/ to cur/. They are updated with the :2, - but since nothing was actually done, no flags are added. So I'm left with a quandry. I guess the simple question is, Should mail in cur, EVER not have a flag? I suppose if it were marked as UNSEEN after being SEEN, that's possible. So I just answered myself there :) Is it possible to have Dovecot NOT move a file from new/ to cur/ until a flag has been assigned to the mail? Just from a, possible, performance standpoint - it seems when accessing an INBOX from a PHP webmail system with MANY new mails, there is an unnecessary(?) mass move of these files to another folder. Thoughts? Rick

Since it's a production server and I just started working for these people, I'll try to reproduce the previous error without affecting the users e-mail (since their server is now running 1.0.15). As soon as I do that I'm going to give you a feedback for sure, if the problem persists or not. The user who reported to me the error may not have the messages that were triggering the errors, so I can't guarantee that I'll be able to reproduce the error again. Thanks for the quick response! > > > server dovecot: child 553 (auth-worker) killed with signal 11 > > This is also interesting. A crashing imap process should have no > effect on auth-worker. Can you get a gdb backtrace from that? Ok, the same as above. thanks again! > = -- Powered by Outblaze

[Dovecot] Forwarding with Dovecot
by Sawtooth500 02 Mar '09

02 Mar '09

I'm using Dovecot with Postfix as my MTA I need to set up forwarding with Dovecot. I create a .forward file in my user's home directory, and in the .forward file I put destination_email_address email(a)example.com. Well, it got delivered to the forwarded email just fine. But the sender also got an undeliverable email from the dovecot mailbox and a copy was not saved in the dovecot mailbox. I need emails forwarded, and a copy saved in the dovecot mailbox. Thanks in advance for the help! -- View this message in context: http://www.nabble.com/Forwarding-with-Dovecot-tp22244316p22244316.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Remote storage
by Daniel L. Miller 01 Mar '09

01 Mar '09

What options are available for remote storage, i.e. storage devices directly mounted on the machine running Dovecot? I've seen discussions of NFS usage - but my experiences with NFS in times past have been poor. CIFS has worked well for me for non-mail use - would this be suitable? Or is there another method I've not considered? -- Daniel

[Dovecot] Compilation Issue on Old Boxes with macro in src/master/main.c
by Kevin A. McGrail 28 Feb '09

28 Feb '09

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box. The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure --with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d --sysconfdir=/etc --localstatedir=/var I've used this to compile on other older boxes with success. And I compared the command lines and they are identical. This is the error I get with src/master/main.c main.c:365:1: directives may not be used inside a macro argument main.c:364:16: unterminated argument list invoking macro "printf" main.c: In function `print_build_options': main.c:372: syntax error before string constant Changing the function to a simpler function without the ifdef's resolves the issue and dovecot compiles. I would really like to know why two boxes with the same compiler are failing on one but not the other. Perhaps there's some program or library or preprocessor or path or something out of whack. Especially since using gcc 2.96 on the same box works! However, I since this is a simple options output routine and (from my cursory read) there may be some standards issue with this technique, I've also patched the issue. http://www.peregrinehw.com/downloads/dovecot/dovecot-1.1.11-build_options_m… Thoughts?

[Dovecot] allow_nets
by CJ Teets 28 Feb '09

28 Feb '09

Hello, Im using Ubuntu 8.10 with Dovecot 1.0.10. I am using passwd files, not a MySQL database. I have 2 files, a "users" file, and a "passwd" file. I have added: allow_nets=10.1.10.1 to the end of a specific users entry in the users file. When that user tries to login, I get the following in the logs: dovecot: 2009-02-28 09:06:59 Error: IMAP(bob(a)mydomain.com): Ambiguous mail location setting, don't know what to do with it: allow_nets=10.1.10.1 (try prefixing it with mbox: or maildir:) dovecot: 2009-02-28 09:06:59 Error: IMAP(boo(a)mydomain.com): Mail storage creation failed with mail_location: allow_nets=10.1.10.1 dovecot: 2009-02-28 09:06:59 Error: child 4174 (imap) returned error 89 here is the line from my users file: bob@mydomain.com::5000:5000::/home/vmail/ mydomain.com/:/bin/false::allow_nets=10.1.10.1 here is the corresponding line from the passwd file: bob@oldschoolpunk.com:$1$evcHgrbC$BuyQRCspMzTpD8zkphxo0/ My goal is, that I want to allow this user to check email ONLY from the IP specified (i.e. 10.1.10.1) I just can't seem to get this working... Am I going about something the wrong way? Thanks!

[Dovecot] Custom flags in v1.0.15
by Pascal Mouret 28 Feb '09

28 Feb '09

Hello all, I'm having problems with setting custom flags on a dovecot imap setup, with mbox mail store. I was running v1.0rc15 on a Debian Etch box, upgraded recently to v1.0.15, but nothing changed. The problem : I read my mail using IMAP. In Thunderbird (various versions, current one being v2.0.0.19), I can set various message flags (Important, Personal, Work, ... mapped to IMAP as $Label4,$ $Label3, $Label2, ...). I read my mail from several machines, but all changes made on the message flags from one machine won't appear on the others !? Still I've read that those flags are supported in Dovecot. Actually, I logged the IMAP traffic, and saw that Dovecot claims to "handle" them. For instance, I added a flag to a message : Thunderbird > 621 uid store 35150 +FLAGS ($label4) Dovecot > * 6716 FETCH (UID 35150 FLAGS (\Seen \Recent $Label4)) Now, if I close TB, so that changes are written to the mbox file, and if I open that file on a the server with any text editor, the 'X-Keywords' line doesn't appear !? And as a matter of a fact, if I read my mail from any other machine, the flag isn't set ! Anyone knows where the problem can be ? Do I need to upgrade to v1.1 ? Or are custom flags actually supported in v1.0 (which I believe is the case) ? I browsed through the internet and searched the archives of this mailing list but didn't find any clue ... Any help would be much appreciated Thank you very much in advance Pascal Mouret -- Pascal Mouret Responsable du Service Informatique Polytech' Marseille, Université de Provence 60, rue Joliot-Curie / 13453 Marseille cedex 13 Mel : pascal.mouret(a)polytech.univ-mrs.fr Tel : 04 91 11 38 04 / Fax : 04 91 11 38 54

[Dovecot] Dovecot + Postfix Mail Forwarding Question
by Taras Hryniw 28 Feb '09

28 Feb '09

I have dovecot and postfix set up on debian lenny. Squirrelmail is used to access the mail. I put a .forward file in my user's home directory, and that sure gets the job done of forwarding email, but I need a copy saved on the local machine as well. How do I do that?
