[Dovecot] new user setup trouble
by Will Ling 30 Dec '05

30 Dec '05

Hi again, I am still trying to run Dovecot but persistently get the errors Corrupted transaction log file and Lost transaction log file. I cannot find any reference to this problem that will help, I have checked the file permissions and locks and cannot see any obvious cause. Could somebody please advise what I might be doing wrong or direct me to somewhere else that I can ask for or find help. Below is some information about the problem.

[Dovecot] Dovecot index cache regeneration
by John Newman 30 Dec '05

30 Dec '05

Hi, We've been using dovecot in the lab now for quite a while and really like the results we're seeing. Underlying dovecot we're using maildir mailboxes. We have the need to manually remove maildir files from time to time. That is, by hand (we'll, actually by script) but not via imap or pop. Dues to dovecot's index caching (which I might add, we love most of the time) imap clients still continue to display the message once they're gone (as we'd expect). However, in this instance it's not what we're after. So my question is, what is the "dovecot recommended" way to force the index cache to regenerate. We really don't want to delete the entire index cache for a particular mailbox as larger mailboxes will then need to unnecessarily regenerate indices on unaffected messages. Many thanks for any tips you can provide. John.

[Dovecot] dovecot INSTALL
by Tom Lee 30 Dec '05

30 Dec '05

Hello, I just tried dovecot-stable-20051206.tar.gz. It takes me one additional day to get it work. >From INSTALL file, it failed to miss the following installation steps: 1) needs to create the file /etc/pam.d/dovecot 2) needs to create the directory /etc/ssl/certs/ and /etc/ssl/private/, configure doc/dovecot-openssl.cnf, chmod +x doc/mkcerts.sh doc/mkcerts.sh Not sure why it is not in the the file INSTALL. For pop3 client configuration, I wonder if it is OK for me to use: #outlook-no-nuls: # Outlook and Outlook Express hang if mails contain NUL characters. # This setting replaces them with 0x80 character. # oe-ns-eoh: # Outlook Express and Netscape Mail breaks if end of headers-line is # missing. This option simply sends it if it's missing. pop3_client_workarounds = outlook-no-nuls, oe-ns-eoh or dovecot can only allow one such as: pop3_client_workarounds = outlook-no-nuls Thanks. Tom

[Dovecot] LDAP authenticated bind support
by J.M. Maurer 30 Dec '05

30 Dec '05

Recently at Better.be we implemented LDAP authenticated bind support for dovecot. A patch against CVS HEAD is attached. I have not tested it against all possible configurations one can use, but the basic operation seems to be right. As documented in the patch, it adds one new option to the dovecot-ldap.conf configuration file: # Set "auth_bind" to "yes" if you want to use "authenticated binds" # as a login validation mechanism. NOTE: the pass_attrs option # will (naturally) be ignored if you enable this auth_bind = yes Authenticated bind support is implemented asynchronously. This involves 2 asynchronous calls: the first being 'ldap_search' to find the dn to bind against and the second being the actual 'ldap_bind' call. I'd love to hear some feedback on this. Regards, Marc Maurer Better.be B.V.

[Dovecot] Migrating from Courier-IMAP to Dovecot
by Andreas Mimz 27 Dec '05

27 Dec '05

Hi! I'm currently trying to migrate from courier-imapd to dovecot... Unfortunately I'm experiences some difficulties here... Since I don't want any user to notice the change of the server backend I've tried changing the namespace in dovecot.conf to namespace private { separator = . location = maildir:~/Maildir prefix = INBOX. inbox = yes hidden = no } With this setting almost everything works fine! Almost... ;-) Squirrelmail won't show 'INBOX' on the left side of the folder tree... If I configure dovecot without the 'INBOX.' prefix it works fine in Squirrelmail, except that all other eMail clients show all sub-folders as a sub-folder of root and not the inbox... root \- inbox \- sent \- trash \- drafts \- private \- spam instead of root \- inbox | \- sent | \- trash | \- drafts | \- private | \- spam any Idea what could be wrong? I've read the wiki about the courier-migration and also tried the conversion script ... but something is wrong I'm afraid... thanks in advance, Andreas

[Dovecot] inbox problems when moving from server to server
by Eric S. Johansson 27 Dec '05

27 Dec '05

this is probably an FAQ but I moved all the mailboxes from a gentoo server to an ubuntu one and all old inbox messages "disappeared" for. New messages appear and can be read, deleted etc. the old messages can still be found in the Maildir/cur directory like they were on the old mail server. Ownership was changed to user:user and is 600 permissions. Dovecot version: 0.99.14-1ubuntu1 all other mailboxes are fine, all messages visible as far as we can tell. ideas?

[Dovecot] Corrupted transaction log file
by Will Ling 24 Dec '05

24 Dec '05

Hi, I am new to dovecot and have just got it up and running on mandrake 8.2. Dovecot seems to be running OK, I can telnet in and log in and Mail on OS X will get the folder list but if a client selects a mail box I get an error back. I cannot find any help anywhere on the errors I'm getting so I hope this is the right place to ask. Please see the log file below. Any clues to the problem would be greatly appreciated. This was after an attempted login from Mail then another try using Mutt locally: dovecot: Dec 24 16:17:44 Info: Dovecot v1.0.alpha5 starting up dovecot: Dec 24 16:17:51 Info: imap-login: Login: user=<will>, method=PLAIN, rip =10.0.128.58, lip=10.0.128.55 dovecot: Dec 24 16:17:51 Error: imap(will): Corrupted transaction log file /home /will/mail/.imap/test/dovecot.index.log: record size too small (type=0x20, offse t=24, size=0) dovecot: Dec 24 16:17:51 Error: imap(will): Lost transaction log file /home/will /mail/.imap/test/dovecot.index.log seq 2 dovecot: Dec 24 16:17:51 Error: imap(will): Lost transaction log file /home/will /mail/.imap/test/dovecot.index.log seq 2 dovecot: Dec 24 16:17:56 Error: imap(will): Corrupted transaction log file /home /will/mail/.imap/INBOX/dovecot.index.log: record size too large (type=0x20, offs et=24, size=201326616, end=48) dovecot: Dec 24 16:17:56 Error: imap(will): Lost transaction log file /home/will /mail/.imap/INBOX/dovecot.index.log seq 2 dovecot: Dec 24 16:17:56 Info: imap-login: Login: user=<will>, method=PLAIN, rip =10.0.128.58, lip=10.0.128.55 dovecot: Dec 24 16:17:56 Error: imap(will): Lost transaction log file /home/will /mail/.imap/INBOX/dovecot.index.log seq 2 dovecot: Dec 24 16:17:56 Error: imap(will): Lost transaction log file /home/will /mail/.imap/INBOX/dovecot.index.log seq 2 dovecot: Dec 24 16:18:46 Error: imap(will): Corrupted transaction log file /home /will/mail/.imap/INBOX/dovecot.index.log: record size too large (type=0x20, offs et=24, size=603979800, end=48) dovecot: Dec 24 16:18:46 Info: imap-login: Login: user=<will>, method=PLAIN, rip =127.0.0.1, lip=127.0.0.will1, secured Regards, Will -- Will Ling

[Dovecot] PATCH: Dovecot SASL authentication for Postfix 2.3-20051220
by Timo Sirainen 24 Dec '05

24 Dec '05

Tested with PLAIN authentication. Doesn't require any external libraries. Building: make makefiles CCARGS="-DUSE_SASL_AUTH" If you want Cyrus SASL support also (eg. for SASL client), just follow SASL_README instructions normally. main.cf: smtpd_sasl_type = dovecot # non-chrooted smtpd: #smtpd_sasl_path = /var/spool/postfix/private/auth # chrooted smtpd: smtpd_sasl_path = /private/auth dovecot.conf: auth default { .. socket listen { client { path = /var/spool/postfix/private/auth mode = 0666 } } }

[Dovecot] Re: PATCH: Dovecot SASL authentication for Postfix 2.3-20051220

I'm adding the finishing touch to the Postfix Dovecot plug-in, to be released with snapshot 20051223. The plug-in code quality is generally very good. I had two observations, both of minor importance: - The authentication server protocol uses the TAB character as a delimiter, so it is critical that legitimate user names don't contain this character. This is of course trivial to ensure with the authentication server implementation, so I will not worry about it. - I noticed that the plug-in did not satisfy one Postfix principle, namely that operations be bounded in time. I added a time limit for connect, read and write operations. Postfix will time-bound all operations anyway, but the diagnostics of the watchdog timer are less specific and therefore less useful.

[Dovecot] Thinking about switching from courier-imap to Dovecot: 2 simple questions
by kadafax 23 Dec '05

23 Dec '05

Hi, I'm using RHEL4 and since the dovecot RPM is present in the main repository, I'm thinking about switching from courier-imap (with whom I've got trouble to update) to Dovecot. Here are two questions about Dovecot (google didn't answer me): 1. Is it possible for dovecot to use the bind mecanism against ldap for authentification purpose. My main concern is to avoid the clear-text password in the dovecot-ldap.conf file. With courier-imap, the process simply bind to the ldap tree with the users's supplied login/password. No need for a special authentification purpose user. 2. Does imap's dovecot implementation support folders imbrication (more than one level folders) ? Thanks, kfx.

[Dovecot] Dovecot & pam_mkhomedir
by Stroller 22 Dec '05

22 Dec '05

Hi there, Does anyone have Dovecot working correctly with pam_mkhomedir, please? I seem to be going through quite a number of IMAP servers this week, trying to find one that will not only authenticate against a Windows domain but which will also create home directories for users the first time they log in. I'm using winbind to do the authentication & that seems to be doing the trick in the first instance - if I log in using Squirrelmail I see entries written to the system log saying: Dec 16 11:58:35 baby pam_winbind[9319]: user 'ned' granted access I have set Dovecot to log to /var/log/mail and in that I see only three entries saying: imap-login: Dec 16 11:58:36 Info: Login: ned [127.0.0.1] But Squirrelmail gives: ERROR: Could not complete request. Query: SELECT "INBOX" Reason Given: /etc/pam.d/imap says: #%PAM-1.0 auth required /lib/security/pam_winbind.so account required /lib/security/pam_winbind.so session required /lib/security/pam_mkhomedir.so skel=/etc/skel umask=0022 If I use the same configuration for SSH then the user's home directory is created upon authenticaton, but not with Dovecot. I chose to try Dovecot because I understood it handled PAM session wossisnames, which Courier-IMAP doesn't. My dovecot.conf is attached - I'm wondering if the problem could be with the "auth_userdb" setting, but `getent passwd` does show an entry for the user: # grep ned /etc/passwd # getent passwd | grep ned ned:x:10012:10000:Ned Nedbody:/home/DOMAIN/ned:/bin/false # Many thanks in advance for any advice or suggestions - I'd really like to understand what's going on here. I believe I can authenticate against the domain using LDAP / Active Directory, but since I don't know if that'll help I'd rather not go that route yet. If I first try to log in using ssh with pam_mkhomedir enabled then the users' home directory is created successfully & I can subsequently log on in Squirrelmail. But it's important to me that I shouldn't have to create users' home dirs for them - I should be able to add them on the Windows domain controller & just tell them to log in to their email - the home dir on the mailserver should be created automagically when they authenticate against the domain.

I am not having much luck with resolving my authentication issue. The environment is "SunOS 5.10 Generic_118822-11 sun4u sparc SUNW,UltraSPARC-IIi-cEngine". dovecot-1.0.alpha5 ./configure --with-passwd --with-shadow --with-pam --with-checkpassword --with-mysql --with-storages=maildir # telnet 172.16.0.40 143 Trying 172.16.0.40... Connected to 172.16.0.40. Escape character is '^]'. * OK mailhub is for business purposes only. Usage is monitored. A01 login username mypassword * BAD [ALERT] Plaintext authentication is disabled, but your client sent password in plaintext anyway. If anyone was listening, the password was exposed. A01 NO Plaintext authentication disabled. A04 Logout * BYE Logging out A04 OK Logout completed. Connection to 172.16.0.40 closed by foreign host. *I have tried adding digest-md5 cram-md5 and shadow but Dovecot will not start.* auth default { # Space separated list of wanted authentication mechanisms: # plain digest-md5 cram-md5 apop anonymous gssapi mechanisms = plain *Dovecot will not start when I tried these options. Maybe I am entering this wrong?* passdb shadow { /etc/shadow } passdb passwd { /etc/passwd } Any assistance would be appreciated. -- Best regards, Michael
