[Dovecot] imap folders
by Roger D. Vargas 26 Jul '04

26 Jul '04

Until last week I was using old imap daemon, then i installed FEdora Core 2 and it was replaced by dovecot or cyrus. I decided to use dovecot, and managed to configure it. But I still have a problem, the users imap folders (stored in their home dirs) arent visible, only the inbox. How can I recover those folders? -- Roger Durañona Vargas Linux user #180787 A cada momento nos rodea lo desconocido. Es alli donde uno tiene que buscar el conocimiento. Paul Muad'Dib Atreides.

[Dovecot] Some users cannot read mail: assertion failed
by Robert Munteanu 26 Jul '04

26 Jul '04

Hi all! I am a recent user of dovecot. First of all, the migration from UW-IMAP was definitely worth it. But now I've run into some troubles. Two of my users complain that they can't read their Inboxes, but other folders work fine. The error message I get in the logs look like: lynx imap(gheorghe.bancos): file buffer.c: line 357 (buffer_set_start_pos): assertion failed: (abs_pos <= I_MIN(buf->used, buf->limit)) lynx dovecot: child 1823 (imap) killed with signal 6 The problems have been reported with both MS Outlook and SquirrelMail. What causes this problem and how can I fix it?

[Dovecot] Passwords in passwd-file
by Andrew Boothman 25 Jul '04

25 Jul '04

Hi! I'm trying to use MD5 hashed password in a passwd-file (not the system one). I've set auth_userdb = passwd-file /my/passwd/file auth_passdb = passwd-file /my/passwd/file auth.txt additionally describes a syntax like: auth_userdb = passwd-file[34] /my/passwd/file to denote MD5 passwords in the file, but I've been unable to get any combination of using []'s after passwd-file to work. Dovecot complains: "Unknown userdb type". How is it best to store passwords in a passwd-file using Dovecot 0.99.10.7? Ideally I want to use PHP to generate the passwords being entered into the file. Thanks for any pointers! Andrew

[Dovecot] Bug? 1.0.0-test28 NFS locking problems
by Tim Southerwood 24 Jul '04

24 Jul '04

Hi Slight problem - linux 2.4 running dovecot, Solaris 2.8 home directory server. Full lockd support etc. I had to make the following code patches (at end of mail for clarity) to get dovecot to read the users mbox files at all. 1) fcntl with F_SETLKW will not work against a Solaris 2.8 server as proved with a small test program. Other forms of fcntl (ie F_SETLK) are OK. I noticed there are some code witches, but setting mbox_lock_timeout=0 only seems to knock one of the fcntl's over to F_SETLK 2) O_CREAT | O_EXCL are documented not to work over NFS properly (see man open(2) on linux). So I knocked out the O_EXCL and combined with (1) dovecot will talk over NFS to remote mbox files. THESE ARE NOT VIABLE CODE PATCHES They illustrate a problem I found - they are hackish and totally wrong. I'm not sure of the best way to correct this problem cleanly, so I am just submitting it as a potential bug.

[Dovecot] RFE: MD5 encryption with for plain text passwords
by Felix Schwarz 23 Jul '04

23 Jul '04

Hi, due to compatibility issues with mail clients I think I have to use plain text authentication. In order to secure the passwords during their transport I'll use SSL encryption. After reading some documentation I think that I'll have to store the passwords as plain text in the authdb. That is something I dislike very much as it is a (imho) good tradition for unix to store only encrypted passwords for security reasons. I would like to see the possibility in dovecot to store the passwords for plain text authentication md5 encrypted. That should be easy to implement (just one md5 encryption before comparing the given password with the stored one) and could improve security. As this would be an api change it should be made configurable (and in the first versions this setting should default to the actual behavior). How do you like this idea? Maybe I can provide a patch but I won't work on this if you won't include it within dovecot at all. And last but not least I want to thank you for your great support! I really appreciate it! :-) -- Felix

[Dovecot] CRAM-MD5
by Felix Schwarz 22 Jul '04

22 Jul '04

Hi, after getting dovecot working with PostgreSQL and plaintext passwords I tried to use md5 encrypted passwords with mozilla. www.roughtrade.net/dovecot says that Mozilla only supports CRAM-MD5 and that CRAM-MD5 is included in HEAD. Now I have two questions: 1) Is the md5 hash stored in passdb with cram-md5 the same as in digest-md5? 2) Is a new dovecot stable build planned within the next two weeks (which includes CRAM-MD5)? (I guess the answer is no :-( 3) Are there any dovecot rpms with pgsql and CRAM-md5 supprt? -- Felix

This did the trick. It seems to be working fine now. Thanks for your help. I can now go on to further testing and imaps/pop3s. I am seriously looking at Dovecot for our production mail server.

[Dovecot] Dovecot auth problem on FreeBSD 4.10
by Viren Patel 22 Jul '04

22 Jul '04

Hello. I am trying to setup Dovecot on an Alpha running FreeBSD 4.10. I am simply trying the imap/pop3 protocols at this time. But with both protocols the log message I get is: pop3-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 or imap-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 I have tried various combinations of: auth = default|plain|pam auth_userdb = passwd auth_passdb = passwd|shadow|pam|passwd-file but nothing works. What am I doing wrong? Thanks. Viren Patel University of Texas at Austin
