[Dovecot] Status of Shared Folders?
by Charles Marcus 24 Oct '06

24 Oct '06

Hi Timo, I'm just curious... is the Wiki up to date regarding the status of Shared Folder support for Dovecot? Specifically, does Dovecot still have a problem with Read-only (for certain users) maildirs using Shared folders defined via namespaces? I'm about ready to start testing a rollout, but wanted to find out what to expect with regard to Shared Folders - we use them extensively right now (Courier-imap), so it is important for us. Having per-user read/unread flags will be a very nice bonus, but I don't see anything about support for those... -- Best regards, Charles Marcus I.T.

[Dovecot] converting from courier questions
by Aaron P. Martinez 24 Oct '06

24 Oct '06

I currently run postfix and courier on my mail servers with squirrelmail. The problem with courier is it seems to run so slow. The webmail takes forever to load if you have many mails. I have this set up in virtual domains with all longin and path info in an mysql database. I just joined the list and DID google before asking, hope this isn't a common question. With courier it looks for a "homedir" and then a "maildir".. I tried doing a query as such: user_query = SELECT Homedir and Maildir AS home, VUID AS uid , VGID AS gid FROM users WHERE Email_address = '%u' to no avail, is my sql wrong or can you not cat the homedir and maildir fields together to create the complete path to home? . i got around the homedir problem by setting mail_chroot = /var/spool/postfix/virtuals (is this the general way, only way?) and then in my dovecot-mysql.conf i have user_query = SELECT Maildir AS home, VUID AS uid , VGID AS gid FROM users WHERE Email_address = '%u' This almost worked but as i was watching the logs it was looking for /var/spool/postfix/virtuals/<somedomainname>/Maildir//Maildir In courier the "Maildir" is not implied, it has to be spicified in the database. I have a LOT of users and would love to avoid chaning every line in my database. or add another filed just for dovecot. I would also like the ability to switch back and forth for testing with courier.. Is there anyway that this can be done? Thanks in advance, Aaron

[Dovecot] Creating MySQL db
by Gerard Seibert 24 Oct '06

24 Oct '06

I was just wondering if anyone was using or aware of a program to create MySQL Data Bases for use with Dovecot. For Postfix, there is the 'Postfixadmin' application. I have not seen anything similar for Dovecot and was wondering if one existed. My system consists of all virtual users. -- Gerard Never attribute to malice what can adequately be explained by incompetence.

[Dovecot] problems with authentication
by Paul Aguirre 24 Oct '06

24 Oct '06

Hi, I have some problems I'm using fetchmail to get my mail from the server to a local server, but the problem is that my user name of the mail is "user@virtualdomain" and I can't make a system user with "@" on centos. So, I want to know how can I tell to dovecot the user "user@virtualdomain" is associate to a sistem user "user.virtualdoman". Or if any one knows another solution. Thanks Paul __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[Dovecot] Proxy using passd file
by Clayton Epp 23 Oct '06

23 Oct '06

I'm trying to create a proxy using passwd files. Can I use the existing passwd files created by the system (ie passwd and shadow) or do I have to create new passwd files for the email proxy users? How would the passwd and shadow files for a proxy using passwd files look? I've tried the example on the wiki but I'm not getting anywhere, pop and imap requests are not getting sent to the other server.

Re: [Dovecot] any idea why the mail downloading is slow?

Indeed, with Tbird, the download is faster with KMail. Any idea what could be the problem? I don't think this is a "bug" in KMail; maybe a configuration issue?

The problem appears only when the ldap connection breaks (e.g. remote ldap server restart). We don't use rootbinddn at all. Anyway I just checked the latest version of nss_ldap and now I see interesting new relevant options are available (e.g. nss_connect_policy persist/oneshot). I will give it a try and respond back in a few days. Definately nss_ldap's bad behaviour is not really a dovecot problem. Dovecot has been rock solid here serving 30000 users (4000 different active users every day) on a single server. apap
