[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

[Dovecot] Feature Requests
by Jonathan Vanasco 16 Aug '05

16 Aug '05

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

[Dovecot] Wrong dates in Outlook
by Alexander Tamm 16 Aug '05

16 Aug '05

Hello, We're migrating from Ipswitch Imail to Dovecot. There seems to be a problem with Outlook after converting the emails with mb2md and whole bunch of perl scripts to correct all the idiotic mistakes that Imail has made. Outlook will display the date and time of the conversion as the date of the message, rather than using the Date: header. The same does not occur in Thunderbird or Horde/IMP. Any ideas? Alex
