[Dovecot] Migrating from uw-imapd to dovecot
by Anne Hammond 14 Sep '06

14 Sep '06

We recently switch from up-imapd to dovecot But many users are reporting that they cannot access certain mail folders. The log file has: imap(dws): Sep 14 00:06:19 Error: File isn't in mbox format: /home/research/dws/mail/TaskDL The files in the logs are "MBX mail folders", not "ASCII English text" as are the folders that can be read under Outlook. Can anyone tell me how to fix this? This is a serious problem in switching. I've read the FAQ and documentation but it doesn't speak to this specific problem. Thanks in advance, Anne Hammond Tech-X Corporation

Hi all I've been doing research but haven't found anything yet. Is there a doc to show how to get Dovecot to authenticate directly against active directory.

[Dovecot] Dovecot 1.0.beta9, emails disappearing?
by Martin Végiard 14 Sep '06

14 Sep '06

Hi, I've been using Dovecot successfully for a while and I've recently encountered an issue : I got to work today and half the emails, were deleted... and after careful investigation : - On Monday it seems, the emails magically vanished .. (what I've been told) - My backup from Tuesday morning at 3am, indicates that all the files (mailbox) are intact but the subscription file is missing half the entries. - At noon, on Tuesday, half the subscriptions are still missing and half the files now also missing. Any ideas, known issues, suggestions? Details : # dovecot --version 1.0.beta9 # uname -a NetBSD Z 3.0.1 NetBSD 3.0.1 (GENERIC.MPACPI) #0: Fri Aug 18 08:34:05 EDT 2006 m@Z:/usr/src/sys/arch/i386/compile/GENERIC.MPACPI i386 the server in question is usually just idling away... and nothing abnormal in my logs thanks for your time, Martin

[Dovecot] Quota plugin API documentation ?
by Craig Huckabee 13 Sep '06

13 Sep '06

What is the best reference for the quota plugin API ? I have some code that can return the disk quota from AFS that I would like to add to the existing file system quota plugin (or perhaps create a new plugin) but I am having a hard time deciphering what each function should return and the data formats (e.g. kilobytes versus bytes). Any pointers are appreciated. --Craig

[Dovecot] MySQL Authentication
by Peter Fraser 12 Sep '06

12 Sep '06

Hi all I have this interesting issue. I installed dovecot on FreeBSD 6.1. The install went well. I'm trying to get it to use a mysql database that postfix is already using to authenticate. When I use this in dovecot.conf userdb mysql { args = /usr/local/etc/dovecot/dovecot-mysql.conf } passdb mysql { args = /usr/local/etc/dovecot/dovecot-mysql.conf } I get this error. auth(default): Unknown passdb driver 'mysql' (typo, or Dovecot was built without support for it? Check with dovecot --build-options) This is strange because I did compile it with mysql support. Any ideas here?

[Dovecot] TAB characters in subject header continuation/wrap lines
by Stephen Warren 12 Sep '06

12 Sep '06

I have some emails where the Subject line has been wrapped, and subsequent lines are indented with TAB characters. Specifically, here's a dump of a portion of an email: 0002020 C c : sp nl S u b j e c t : sp [ B 0002040 u i l d b o t ] sp B u i l d B o 0002060 t sp S U C C E S S nl ht ( B l d _ 0002100 g s s d k _ g s s d k _ t e s t 0002120 _ 2 0 0 6 _ 0 9 _ 1 2 _ 0 0 _ 0 0002140 1 _ 0 0 _ I n c r e m e n t a l 0002160 _ 2 ) nl X - B e e n T h e r e : Note the HT about half way through the third line. When I view this email using Thunderbird 1.5.0.5 on Windows XP, with Dovecot 1.0.rc7 running on CentOS 4.3, this TAB character shows up as a funny character in the subject line, as displayed by the Thunderbird. My question is: Should Dovecot be detecting mail header continuation lines that start with a TAB, and stripping the TAB (converting to a space)? I *think* that's what the RFCs implied when I read up on this a few months ago, but I may easily be mis-remembering. A second somewhat off-topic question: When the automated system that sends out these messages sends them to me directly, this problem does not occur, because the email titles are not wrapped. However, when I receive these emails via a mailman mailing list, mailman prepends the text "[Buildbot]" on the front of the title, thus making the title long enough to require wrapping. As such, I imagine that it's mailman that is indenting the Subject continuation line with the TAB character. Is there an issue in mailman - should mailman be indenting with e.g. a SPACE character, or is mailman's action perfectly legal? Thanks for any pointers.

[Dovecot] Using pgsql with 'cram-md5 auth' and 'hmac-md5 scheme'
by Jonathan Ballet 12 Sep '06

12 Sep '06

Hello, I want to use PostgreSQL to store my Dovecot users. I setup a very basic configuration, following word for word this page http://wiki.dovecot.org/DovecotPostgresql and it works ... almost. In fact, it works if I use PLAIN password scheme in my database. However, I would like to store them encrypted. But, if I replace the password field for my user with {HMAC-MD5}-... (the password generated by dovecotpw), it doesn't work. Here is the log, using PLAIN password scheme (all debug options activated) : =================================================== auth(default): client in: AUTH 1 CRAM-MD5 service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 auth(default): client out: CONT 1 PDU3NTgxMTE5MTcwMTYzNjguMTE1ODAxMTQzN0BkZWI2ND4= auth(default): client in: CONT 1 am9uIDJjN2RmMDVmZWZiNWU4MmE0MzFkMjM2YThhYzc2MDAx auth(default): sql(jon,127.0.0.1): query: SELECT userid as user, password FROM users WHERE userid = 'jon' auth(default): password(jon,127.0.0.1): Credentials: 3fd9989457cb3edf1fb8d31dddaf11f3f0efee3423aeb9ebf9bbe981f86a079b auth(default): client out: OK 1 user=jon auth(default): master in: REQUEST 1 23748 1 auth(default): sql(jon,127.0.0.1): SELECT home, uid, gid FROM users WHERE userid = 'jon' auth(default): master out: USER 1 jon home=/var/mail/jon/ uid=5000 gid=5000 IMAP(jon): Effective uid=5000, gid=5000 IMAP(jon): maildir: data=/var/mail/jon IMAP(jon): maildir:root=/var/mail/jon, index=/var/mail/jon, control=, inbox= imap-login: Login: user=<jon>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured IMAP(jon): Disconnected: Logged out And here is the log, using HMAC-MD5 password scheme (all debug options activated too) : ===================================================== auth(default): client in: AUTH 1 CRAM-MD5 service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 auth(default): client out: CONT 1 PDI0MDc4NTQzMDc5NjU2NTIuMTE1ODAxMTkxNUBkZWI2ND4= auth(default): client in: CONT 1 am9uIDViNmE4NDI5ZjUzZTQ3YTEzZmEzNjhiOThlYjI5OTFi auth(default): sql(jon,127.0.0.1): query: SELECT userid as user, password FROM users WHERE userid = 'jon' auth(default): password(jon,127.0.0.1): Credentials: auth(default): cram-md5(jon,127.0.0.1): password mismatch auth(default): client out: FAIL 1 user=jon imap-login: Disconnected: user=<jon>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured The login + password used for those tests are 'jon'/'jonpwd'. In the second example, I didn't get any Credentials, whereas in the first case (PLAIN scheme), the Credentials output correspond to the 'dovecotpw' generated password (as in `dovecotpw -s HMAC-MD5 -p jonpwd`). I don't know if it's normal or not. So, I'm not sure what to do next :/ I use this kind of 'auth mechanism'/'password scheme' on another computer, with passwd-like files, and it works. So, I don't know why the same data, coming from another location, doesn't work. Any help would be greatly appreciated ! Thanks, -- Jonathan
