[Dovecot] Dovecot lda woes
by Brad 21 Feb '06

21 Feb '06

Having some painful problems with the dovecot lda and getting it to (a). Just work (b). Work with sendmail This is how I have dovecot setup (appropriate dovecot.conf snippets included) protocol lda { module_dir = /usr/local/lib/dovecot/lda postmaster_address = postmaster(a)bradphinney.com auth_socket_path = /var/run/dovecot-auth-master } auth default { .... # passwd-like file with specified location passdb passwd-file { # Path for passwd-file args = /etc/dovecot-passdb } userdb static { args = uid=500 gid=500 home=/var/mail/%u mail=mbox:/export/dovecot/%d/%u/ nice=10 } ... } Here is what deliver is set up as -rwsr-sr-x 1 dovecot dovecot 2070623 Feb 19 18:22 deliver* I drop sendmail into debugging mode so I can at least see if it is resolving the address correctly. Here is my mailertable entries : testdomain1.com dovecot:dovecot I fire up sendmail. telnet to port 25 and see if I cant get some mail delivered. Here is what sendmail spits out Feb 20 18:54:18 titan sendmail[6475]: k1KNqWti006459: to=<echo(a)testdomain1.com>, delay=00:01:16, xdelay=00:00:00, mailer=dovecot, pri=120016, relay=dovecot, dsn=5.3.0, stat=unknown mailer error 89 Not good. On a hunch .. I change the permissions on the dovecot log to be 777. Now .. I get a different error .. Feb 20 18:12:14 titan sendmail[6014]: k1KNBQ1e006006: to=<echo(a)testdomain1.com>, delay=00:00:03, xdelay=00:00:00, mailer=dovecot, pri=120012, relay=dovecot, dsn=4.0.0, stat=Deferred: dovecot mailer (/usr/local/libexec/dovecot/deliver) exited with EX_TEMPFAIL Any ideas ?

[Dovecot] Problems with authentication
by Lapo Luchini 20 Feb '06

20 Feb '06

Hi there. I've got a running qmail+vpopmail+mysql5 server on FreeBSD and I would like to give IMAP access to it (both for user's sake and to have a decent webmail), so I decided to install dovecot (it certainly does its work on my home box). Problem is: I haven't had success with authentication. At first I tried the most obvious: using the vpopmail backend. Unfortunately I received lots of "vmysql: MySQL server has gone away" just like in http://article.gmane.org/gmane.mail.imap.dovecot/10321 So I decided to spice up a query to vpopmail's MySQL table, and there another problem was waiting for me: "Access denied" just like in this thread http://article.gmane.org/gmane.mail.imap.dovecot/9077 Only difference: in my case using OLD_PASSWORD() didn't solve the problem and -thinking about it better- couln't possibly have solved it: that FreeBSD is a recent fresh install and I installed MySQL 5.0.18 from sources using the "ports" system, so a library with no support for new PASSWORD() has never seen the light on that box. I kinda went around the problem using a shell script to dump the MySQL table to a SQLite file and authentication dovecot against that, but while this work-around can do for a little bit I'd really like to solve the problem itself, and avoid having to keep ni sync those two DBs (no, unfortunately vpopmail doesn't support SQLite, else I'd use that: it would also have the nice side-effect that a "down" on mysql side wouldn't hurt the mail subsystem). Any suggestions or idea how I could solve or, at least, better diagnose the problem(s)? Yours, Lapo

[Dovecot] rawlog for Dovecot proxies
by Bill Boebel 20 Feb '06

20 Feb '06

Is there a way to use rawlog to log the full IMAP session when running Dovecot as a front-end proxy for other IMAP servers? If so, how?... I couldn't figure it out. Or is there another debug setting that can give me this information? If not, what is the best method to sniff the IMAP session for debugging a proxy?... ethereal? Thanks, Bill -- http://billboebel.typepad.com/

[Dovecot] Updating the web?
by Peter Lindgren 20 Feb '06

20 Feb '06

Hello! I was looking for some information about which signals I can send to dovecot to do various things, but I couldn't find it. Since it's a wiki, is it ok to just edit the pages, or should I post here first? I thought I'd check with Timo and you guys first, maybe I missed that page that describes the signals... If it's ok, I can edit or add a new page. /Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] IMAP stress testing tool
by Timo Sirainen 20 Feb '06

20 Feb '06

I updated my IMAP stress testing tool to support also APPENDs and print some nice statistics. If you want to try for yourself, it's here: http://dovecot.org/tools/imaptest.c I thought about adding some more features in future to it, such as: - Add a header to each appended message containing MD5 sum of it. When fetching, verify that the MD5 sum is valid. - Do randomized fetch requests (headers, size, flags, etc.) - Do randomized search requests - sort, thread

[Dovecot] Messages disappear and reappear when I check mailbox using KMail
by Lincoln Peters 20 Feb '06

20 Feb '06

Not sure if this is a Dovecot bug or a KMail bug, but since it only seems to happen to people using KMail to access a Dovecot server or a Novell NetWare IMAP server, I thought I should mention it here. <http://bugs.kde.org/show_bug.cgi?id=121866> From the bug report: When I check for mail on an IMAP account (not disconnected), all recently-received messages disappear prior to any mail check, any new messages appear, and then the messages that disappeared earlier reappear. This does not seem to cause any harm, but it is horrendously inefficient if there are a lot of messages in an IMAP folder so affected. Any ideas as to what could cause this behavior in a mail client when connecting to a Dovecot IMAP server but not when connecting to other kinds of IMAP servers? -- Lincoln Peters <sampln(a)sbcglobal.net> BOFH excuse #80: That's a great computer you have there; have you considered how it would work as a BSD machine? /~\ The ASCII Ribbon Campaign \ / No HTML/RTF in email X No Word docs in email / \ Respect for open standards

[Dovecot] IMAP and Outlook XP Contacts
by DiskMan 20 Feb '06

20 Feb '06

I was wondering, does Dovecot's IMAP server hand Outlook XP's contact lists? I tried to enter a contact on my IMAP server and received an error from Outlook stating that the Contacts formatting was too complex and thus couldn't be saved. I went ahead and swung my box over to MailDir and scrapped Sendmail for Postfix [for maildir support], I was wondering, would this issue continue? In other words, by swinging over to MailDir, would Dovecot be able to handle Outlook's Contacts information? Will L G

[Dovecot] Another permissions problem?
by Anne Wilson 19 Feb '06

19 Feb '06

The rebuild server is now almost complete. Dovecot is running, and I can telnet and log in. In kmail on this workstation I have created an imap account, for which Inbox was created. I also created Trash and sent-mail as top-level folders, and they display correctly with the cur, new and tmp sub-folders on the server. I now want to create subfolders of Inbox, and there I'm coming unstuck. According to the info box URL: (unknown) Date and time: Saturday 18 February 2006 16:51 Additional information: imap://anne@192.168.0.30:143/INBOX/LAN//;INFO=ASKUSER Possible causes: Your access permissions may be inadequate to perform the requested operation on this resource The location where the folder was to be created may not exist A protocol error or incompatibility may have occurred This is what I have at the moment: ls -al -R ~/Maildir /home/anne/Maildir: total 44 drwxr-xr-x 8 anne users 4096 Feb 18 17:21 . drwxr-xr-x 49 anne anne 4096 Feb 18 17:23 .. drwx------ 2 anne users 4096 Feb 18 17:21 cur -rw------- 1 anne users 5 Feb 18 16:48 .customflags -rw------- 1 anne users 61 Feb 18 17:21 dovecot-uidlist drwx------ 2 anne users 4096 Feb 18 16:48 .INBOX drwx------ 2 anne users 4096 Feb 18 17:21 new drwx------ 5 anne users 4096 Feb 18 16:51 .sent-mail -rw------- 1 anne users 16 Feb 18 16:48 .subscriptions drwx------ 2 anne users 4096 Feb 18 17:21 tmp drwx------ 5 anne users 4096 Feb 18 16:51 .Trash /home/anne/Maildir/cur: total 28 drwx------ 2 anne users 4096 Feb 18 17:21 . drwxr-xr-x 8 anne users 4096 Feb 18 17:21 .. -rw------- 1 anne users 18063 Feb 18 17:21 1140283312.P16651Q0M725303.wkstn.domain.lan:2,FS /home/anne/Maildir/.INBOX: total 32 drwx------ 2 anne users 4096 Feb 18 16:48 . drwxr-xr-x 8 anne users 4096 Feb 18 17:21 .. -rw------- 1 anne users 1608 Feb 18 17:21 .imap.index -rw------- 1 anne users 10264 Feb 18 16:48 .imap.index.data -rw------- 1 anne users 2576 Feb 18 16:48 .imap.index.log -rw------- 1 anne users 1556 Feb 18 16:48 .imap.index.tree /home/anne/Maildir/new: total 8 drwx------ 2 anne users 4096 Feb 18 17:21 . drwxr-xr-x 8 anne users 4096 Feb 18 17:21 .. /home/anne/Maildir/.sent-mail: total 48 drwx------ 5 anne users 4096 Feb 18 16:51 . drwxr-xr-x 8 anne users 4096 Feb 18 17:21 .. drwx------ 2 anne users 4096 Feb 18 16:48 cur -rw------- 1 anne users 5 Feb 18 16:51 .customflags -rw------- 1 anne users 1608 Feb 18 16:48 .imap.index -rw------- 1 anne users 10264 Feb 18 16:51 .imap.index.data -rw------- 1 anne users 2576 Feb 18 16:51 .imap.index.log -rw------- 1 anne users 1556 Feb 18 16:51 .imap.index.tree drwx------ 2 anne users 4096 Feb 18 16:48 new drwx------ 2 anne users 4096 Feb 18 16:48 tmp /home/anne/Maildir/.sent-mail/cur: total 8 drwx------ 2 anne users 4096 Feb 18 16:48 . drwx------ 5 anne users 4096 Feb 18 16:51 .. /home/anne/Maildir/.sent-mail/new: total 8 drwx------ 2 anne users 4096 Feb 18 16:48 . drwx------ 5 anne users 4096 Feb 18 16:51 .. /home/anne/Maildir/.sent-mail/tmp: total 8 drwx------ 2 anne users 4096 Feb 18 16:48 . drwx------ 5 anne users 4096 Feb 18 16:51 .. /home/anne/Maildir/tmp: total 8 drwx------ 2 anne users 4096 Feb 18 17:21 . drwxr-xr-x 8 anne users 4096 Feb 18 17:21 .. /home/anne/Maildir/.Trash: total 48 drwx------ 5 anne users 4096 Feb 18 16:51 . drwxr-xr-x 8 anne users 4096 Feb 18 17:21 .. drwx------ 2 anne users 4096 Feb 18 16:48 cur -rw------- 1 anne users 5 Feb 18 16:51 .customflags -rw------- 1 anne users 1608 Feb 18 16:48 .imap.index -rw------- 1 anne users 10264 Feb 18 16:51 .imap.index.data -rw------- 1 anne users 2576 Feb 18 16:51 .imap.index.log -rw------- 1 anne users 1556 Feb 18 16:51 .imap.index.tree drwx------ 2 anne users 4096 Feb 18 16:48 new drwx------ 2 anne users 4096 Feb 18 16:48 tmp /home/anne/Maildir/.Trash/cur: total 8 drwx------ 2 anne users 4096 Feb 18 16:48 . drwx------ 5 anne users 4096 Feb 18 16:51 .. /home/anne/Maildir/.Trash/new: total 8 drwx------ 2 anne users 4096 Feb 18 16:48 . drwx------ 5 anne users 4096 Feb 18 16:51 .. /home/anne/Maildir/.Trash/tmp: total 8 drwx------ 2 anne users 4096 Feb 18 16:48 . drwx------ 5 anne users 4096 Feb 18 16:51 ..
