[Dovecot] nfs dotlock issues
by Maikel Verheijen 11 May '04

11 May '04

Hi List, While testing with dovecot-1.0-test8 on our platform, I get al lot of these: May 11 11:42:50 mf1 dovecot: imap(user(a)domain.tld): Our dotlock file /var/mail/mounted/d/do/domain.tld/user/Maildir/.INBOX/ dovecot.index.log.lock was modified (1084268570 vs 1084268875), assuming it wasn't overridden This is probably due to some time-issues on our platform, and the load the backend has. (our backends run in a live environment). Can the dotlock code get the timestamp of the file when the dotlock gets created in order to be able to keep the time in sync? Is there another way to prevent those seconds of time-difference? we run ntpd on both our frondends and our backends. Kind regards, Maikel Verheijen

[Dovecot] 1.0-test7
by Timo Sirainen 11 May '04

11 May '04

http://dovecot.org/test/ Lots of bugfixes related to syncing. There's still some left. Somewhat working mbox support: - combined syncing/rewriting uses much less disk I/O than with older mbox code - expunges aren't working yet - last-uid field in X-IMAPbase header isn't updated - it's currently syncing the whole mbox constantly even if it hasn't changed - it isn't hiding the mbox-specific headers from IMAP clients - if mbox hasn't changed, rewriting could start from the message which requires rewriting instead of syncing the whole mbox - syncing could keep the lock file extra two seconds to make sure if someone changes it the file's mtime changes -> as long as only Dovecot is modifying it, we'll never need to sync the whole mbox -> multi-gigabyte mboxes are still fast! One nice thing about this mbox code is that it isn't exactly mbox-specific. Some people are still using formats which use eg. ^A as separator rather than From-line. Some people are using SMTP-formatted data directly ('.' as mail separator, '..' = normal line begins with '.'). These formats should be pretty easy to implement now as all mbox-specific code is in istream-raw-mbox.c file. I'll probably do that once mbox itself is fully working.

[Dovecot] Mail always is delivered to /var/mail/
by Kevin Breit 07 May '04

Hey, I am setting up Dovecot on Debian with Postfix. I am telling Dovecot to use maildir:~/Maildir but it persists in dumping mail in mbox format in /var/mail/username. Can anyone suggest ideas? My config file is attached. Thanks Kevin

[Dovecot] imap indexing error when moving multiple mails
by Hauke Fath 06 May '04

06 May '04

Hi, I've got an 'interesting' problem with a dovecot 0.99.10.4 setup on NetBSD/i386 1.6ZK. dovecot is serving imap only at the moment, using mbox format mailboxes. '/etc/dovecot.conf' is pretty vanilla - among the modified settings, mail_read_mmaped = yes maildir_check_content_changes = yes mbox_lock = fcntl could be relevant. Anyway - from time to time when I move a bunch of mails ( < 1) from a mailbox to another (or to the trash), the client (I've seen it with Eudora 6 on a Mac, with Mozilla 1.6 and Sylpheed on NetBSD) reports an "internal error" and the maillog shows Mar 25 14:07:33 bounce imap-login: Login: hf [130.83.xxx.yyy] Mar 25 14:07:44 bounce imap(hf): Error indexing mbox file /home/hf/Mail/Leute/Marc Wirth: LF not found where expected Mar 25 14:09:30 bounce imap(hf): Error indexing mbox file /home/hf/Mail/Leute/Marc Wirth: LF not found where expected which, if I retry the operation to another time, does not persist and is not strictly repeatable. I've set the number of allowed concurrent connections to '1' on the client, but that doesn't help. Is there anything obvious that I overlooked, or have I tripped over a genuine bug? 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, Fax -3778 / \ Respect for open standards

[Dovecot] Dovecot chrooting
by ?a??µp?? ?a?a???t?? 06 May '04

06 May '04

hello all i am new to dovecot and i have a small problem. I use qmail as a pop3 server and dovecot as imap. my rc script is as follows: -----snip----- #!/bin/sh exec env - PATH="/var/qmail/bin:$PATH" \ qmail-start '|preline procmail' splogger qmai -----end----- thus i deliver mails through procmail so all mails are located to /var/spool/mail. The problem exists when i tested chrooting and found it a very good idea to jail all my users.. *but* still qmail delivers mails to the real /var/spool/mail and not to the /home/chrootusers/var/spool/mail so that dovecot can pick them up. Is there any special configuration in dovecot.conf in order to chroot the /var/spool/mail to /home/chrootusers ? some of my conf: login_chroot = yes valid_chroot_dirs = /home/chrootusers mail_chroot = /var/spool/mail default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u PS: tell me if you need more of the dovecot.conf PS2: sorry for my english its not my native

Thanks, Timo, that did the trick. Also thanks to Quentin for his reply, though I don't understand any of it. As stated, my knowledge of unix is rather limited...

Therefore its timezone is the > default, UTC (formerly known as GMT). As I understand it, it would be a good idea to come up with a more permanent fix. However, I have no idea where to begin. Timo writes about making all logging go through the dovecot-master process – can anyone point me in the direction of information on how to accomplish this? Quentin writes about TZ env. var. (TimeZone?), /etc/localtime and the chroot directory. I'm sorry, Quentin, but I need a bit more info. I have the correct /etc/localtime, as far as I can tell. I've tried looking up TZ env. var. in my man-pages, but haven't come up with anything. I'll copy my /etc/localtime to the login_dir and see if this is enough. Thanks again, guys! /Lars

[Dovecot] Envelope From changed - why?
by Tom Alsberg 04 May '04

04 May '04

Hi there. I am evaluating Dovecot as an IMAP server. I noticed on thing which irritates me. When a user saves a message to an IMAP folder with the Dovecot server, the envelope From line is changed to the address of that user, instead of keeping the From line of the original message. How can I have the original envelope From line preserved when saving messages? -- Tom -- Tom Alsberg - certified insane, complete illiterate.

[Dovecot] Maildir files in cur without info
by Christoph Hohmann 04 May '04

04 May '04

Hi, I have tried to use the same Maildir dovecot uses with another program and encountered the problem that Dovecot seems to move files from new to cur in maildir-sync.c::maildir_scan_dir without adding an info part. On the page http://cr.yp.to/proto/maildir.html is written that mails have to be renamed to uniq:info when moved to the cur directory. Could this be a bug in dovecot? -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/

[Dovecot] Dovecot hangs after 2 or 3 days
by Jens Gutzeit 03 May '04

03 May '04

Hi all, We've some problems with our dovecot installation, its the latest stable compiled on a debian woody box. After 2 or 3 days dovecot hangs, no user can login (pop3 and imap), there's nothing in the logs. The client does allways timeout, if I restart dovecot all works well again. It's a box with s.th. around 400 users, we've enough mem free, load is not a problem, it went from 0.9 to 0.1 after migrating from cyrus-imapd, so this doesn't seem to be hardware related. My dovecot conf is online at: http://mail.sunday.de/dovecot.conf best regards/Mit freundlichen Grüßen Jens Gutzeit -- Tel.: +492151 652945 Ein PC besteht sowieso i.d.R. zu 90% aus faulen Kompromissen, zu 7% aus Elektronikschrott und zu 3% aus wirren Ideen.
