[Dovecot] 1.0alpha1, multiple lock methods?
by Jeff A. Earickson 18 Aug '05

18 Aug '05

Hi, I just upgraded from test80 to 1.0alpha1. I wanted to try something new on the lock_method, so I set: lock_method = fcntl, dotlock I got syslog complaints like: IMAP(username): Unknown lock_method: fcntl, dotlock Can one specify multiple file locking mechanisms? If so, what is the syntax (and can the syntax be shown in the comments of the .conf file)? Jeff Earickson Colby College

[Dovecot] 1.0 alpha1 released
by Timo Sirainen 18 Aug '05

18 Aug '05

As promised a few days ago, 1.0.alpha1 release is now available from Dovecot web page. Changes since 1.0-test80 include only one mbox assert crashfix and removed fsync() call when writing to transaction log, making it a bit faster. I changed the version number also since 1.0-tests to 1.0.alpha. I know '-' is problematic to binary package builders, maybe the new versioning is better?

[Dovecot] Discussion of new sending protocol proposal for IMAP
by Marc Perkel 18 Aug '05

18 Aug '05

Timo, I joined the lemonade list for the new IMAP sending protocol and I mage the following suggestion about using IMAP as a front end for SMTP. The idea would be that a client could authenticate to IMAP, then ask for a tunnel to the SMTP server. - Here's my message. I thought I'd get people thinking. --------------------- OK thanks. I would clarify what I'm proposing. I looked at the current proposal and what I'm proposing might be in addition to rather than instead of the current proposal. LDELIVER as it is now offers capabilities of sending messages and forwarding attachments without downloading them, leaving more power on the server side. This is important for mobile clients with limited power on the client end. What I'm suggesting is something in addition to LDELIVER where we add SMTP-TUNNEL as a capability. This is for laptop users who have to deal with finding an outgoing smpt server and who might be behind a firewall that blocks smtp ports. What is different about my proposal is that what I'm suggesting isn't a straight pass through at the beginning. The client has to talk to IMAP, then authenticate, and then upon successfil authentication would ask for an SMTP connection to the local smtp server. At that point it is a tunneled connection. 1) This allows the IMAP ports to be used for SMTP and avoid port blocking. 2) It uses the same IMAP authentication for SMTP so outgoing SMTP nee not be configured separately. It merely acts as an authenticated condiut to get to SMTP. 3) It would in no way interfere with future advancements in SMTP technology at others were concerned about. 4) Client and server recoding would be trivial. 5) This could be used in place of SMTP-AUTH and would eliminate the need for authenticated SMTP making server smtp configuration easier. So - if you look at it as an addition then you don't have to choose between them.

[Dovecot] dovecot-lda compilation problem and feature request
by Michael Goth 18 Aug '05

18 Aug '05

Hi! I tried to compile deliver from CVS (as described in the wiki), but unfortunately make stopped with the following error: In file included from sieve_interface.h:37, from script.h:31, from addr.y:34: sieve_err.h:7:24: et/com_err.h: No such file or directory make[3]: *** [addr.o] Error 1 make[3]: Leaving directory `/usr/local/src/dovecot/dovecot-lda-CVS/src/libsieve'make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/local/src/dovecot/dovecot-lda-CVS/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/src/dovecot/dovecot-lda-CVS' make: *** [all] Error 2 Any suggestions how to fix this? And a second question about deliver: Is it possible to use a system wide default sieve script which applies to all users that do not have their own sieve script? That would be a great feature to easily set up (and maintain) some defaults for virus/spam filtering. Maildrop does it like this ;-) Thanks, Michael

18 Aug '05

Hello, I too got a problem with dovecot trying to login to MySQL. It connects fine without a password, when i add a password the sql server rejects the connection I know the problem, but don't know enough C++ to fix it. The exerpts from the mysql log are: without password: 050818 11:33:29 8 Connect dovecot@server2 on postfix with password: 050818 11:45:19 12 Connect Access denied for user 'dovecot'@'server2' (using password: YES) As soon as i add a password to the connet string some "'" appear around the username and hostname, which makes the username invalid.

[Dovecot] Failed authentication to a mysql database (bug or PEBKAC?)
by Michael Gabb 17 Aug '05

17 Aug '05

Hello, I'm trying to setup a mailserver running postfix and dovecot with mysql as database backend. Postfix is already running and delivers mails just fine. Unfortunately, dovecot has great problems connecting to the database (using username + password). If I disable the password, everthing works fine. But, thats harakiri, security wise ;-) I tried dovecot-1.0-stable and the latest cvs-nightly (I think from August 9.). With both versions, I get the following error (there are little differences between the to versions, but the meaning ist the same...) dovecot: auth-worker(default): mysql: Connect failed to localhost (my_dbname): Access denied for user 'my_user'@'localhost' (using password: YES) - waiting for 1 seconds before retry My connect string is as follows: connect = host=/var/lib/mysql/mysql.sock user=my_user password=my_password dbname=my_dbname Both versions are compiled with the following settings: ./configure --prefix=/usr --localstatedir=/var --libexecdir=/usr/lib --sysconfdir=/etc/dovecot --enable-ipv6 --with-rawlog --with-ssl=openssl --with-pop3d --with-mysql "make" runs cleanly. Then I use "checkinstall" intead of "make install" because I want to generate an rpm package, but that shouldn't make any difference. Im using the following packages from suse (since im building the server upon a SuSE 9.3): mysql-4.1.10a-3.2, mysql-devel-4.1.10a-3, mysql-client-4.1.10a-3 and mysql-shared-4.1.10a-3 I don't have any clue, why the connect fails. The password and the username are both correct (triple verified ;-)) and the user has SELECT- and USE- Permission for my_dbname. Is there any known bug i didn't know about? Or is this a typical PEBKAC situation? Thanks in advance, Michael -- www.megamimi.de.vu

[Dovecot] Sending email with IMAP instead of SMTP?
by Marc Perkel 17 Aug '05

17 Aug '05

Here's a kind of "outside the box" thought. Why not extend the IMAP protocol to send email? Instead of having to use SMTP if an addition were made to the IMAP protocol then IMAP could transport outgoing mail to the server the same way it moves messages to the server. On the server end Dovecot would deliver outgoing email to the host MTA via localhost:25. The advantage would be that clients need not have to deal with a separate configuration for outgoing email. If they have an IMAP connection and already authenticated and perhaps encrypted, then they can transport outgoing mail over the same connection. Of course - email clients would have to have this feature added as well, but it should be trivial. It could be as easy as moving a message to an "out" box on the server, but the out box really is outgoing email rather than a real imap folder. Am I the first one to think of this?

[Dovecot] Migrating UW-POP3 mbox storage to Dovecot POP3 mbox storage
by Rickard Svorén 17 Aug '05

17 Aug '05

Hi We have an mailserver running RedHat Linux 9.0 with UW-IMAP (imap-2001a- 18.progeny.1.src.rpm), we have user mailboxes in /var/spool/mail/username using the default mbox storage method. Some users have home directories and some dont. They only connect through the POP3 server, not IMAP. We are now migrating both hardware and software to an new server running RHEL 4, i have copied all user mbox files from the old RH9 server to the new RHEL 4 server (/var/spool/mail) but when the users are trying to get their mail they can login but Dovecot is complaining about some IMAP dirs missing, see attached docs. I would like to still use POP3 and mbox with Dovecot, is this possible ? I would rather not have to change the user files. Errors from /var/log/maillog: Aug 11 13:25:15 newmail pop3-login: Login: user0001 [::ffff:82.237.232.61] Aug 11 13:25:15 newmail pop3(user0001): mbox: Can't create root IMAP folder /local/home/user0001/mail: Permission denied Aug 11 13:25:15 newmail pop3(user0001): Failed to create storage with data: mbox:/var/spool/mail/user0001 Aug 11 13:25:15 newmail dovecot: child 9371 (pop3) returned error 89 >From dovecot.conf: #protocols = imap imaps protocols = pop3 #default_mail_env = default_mail_env = mbox:/var/spool/mail/%u Best Regards, Rickard

[Dovecot] Dovecot-lda, sieve and virtual users
by David Blundell 16 Aug '05

16 Aug '05

At the moment I use a script to sort spam etc for virtual users into appropriate folders. I would like to be able to replace this with a per-user sieve script so users can customise their filtering through Imp web-mail. The wiki says that per-user Sieve code should be stored in the users home directories - are there any plans to provide sieve script support for virtual users? Thanks in advance, David

I put them on the wiki page, but I'm not sure if they're read often or whatever. a - Sqlite support I know its been talked about, but it wasn't on the request/todo page until i threw it on there, so i wanted chime in for it as well b - User configurable ports ports are hardcoded in the c source file. it would be nice if these were the defaults, and could be overwritten on the configure file. this way we can run dovecot to test on the same machine as an active imap server, or just have more control over how we run it

Anyway, it seems that dovecot is crashing. A simple restart brings it back up. Its odd that it would work for a while and then crash, is there some kind of remote exploit causing it to crash? It says core dumped, but I'm not sure where it would put the core. Also, all of our stuff is LDAP. We dont talk to local passwd files at all. Is there a way I can run the dovecot-auth process as non root? I know there's an option in the config but i tried it and it did not seem to want to restart (the process). Thanks, Matt
