[Dovecot] Authentication with encrypted passwords
by Sebastjan Trepca 28 Aug '05

28 Aug '05

Hello, I have a postgresql database which contains users that will access dovecot, but their passwords are hashed and I don't have them in plain text. I was reading documentation that you can add tell dovecot which password scheme should it use. For example: password_query = "select '{MD5}'||password from users where userid=%u" Which would mean that dovecot will hash the password with MD5 from client and match it with the one in database. Did I understand this correctly ? Thanks, Sebastjan

[Dovecot] Namespace Feature
by Marc Perkel 28 Aug '05

28 Aug '05

I've never used namespaces and don't quite know what they do. If I add a namespace then do things like shared folders magically appear to users? Also - I wonder if this is possible. I'd like to create a write only shared folder. I know this is unusual but I have a reason. I'd like to have a folder that people can drag spam into to report missed spam. I want to write only so people aren't reading each other's spam. I have a bot that comes by and reads this to train the bayesian filter. Right now I have to create these folders individually. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] Postfix/Dovecot
by Micah Stevens 28 Aug '05

28 Aug '05

Hi, I searched through the maillist archives and the docs, but didn't find anything that directly addresses my question, so here goes if anyone has some time to address it. I'm running a redhat el3 server, with Postfix as the MTA, and I'd like to setup Dovecot to provide IMAP/POP3 services. Postfix uses MySQL lookups to do mailbox lookups, and I configured dovecot to do the same thing. The mail is delivered to /usr/local/virtual/<domainname>/<end.address>/ in maildir format by Postfix. This is working fine. I've setup dovecot, and set it do user auth and user lookups to MySQL. This seems to be working fine as I get no mysql errors from the queries, and my login process (to IMAP from localhost) is fine. Here's a typical scenario: telnet localhost imap Trying 127.0.0.1... Connected to localhost.domain (127.0.0.1 <http://127.0.0.1>). Escape character is '^]'. * OK dovecot ready. 1login micah(a)9250x.com "rigid2" 1 OK Logged in. 2 select INBOX 2 NO If I look in the directory for micah(a)9250x.com I find: # ls cur new tmp The permissions are 777 for now to eliminate that possibility. The dovecot log file lists: imap-login: Aug 28 12:27:11 Info: Login: micah(a)9250x.com [127.0.0.1<http://127.0.0.1> ] each time I log in, and nothing after that indicating why it's not seeing any mail. Why isn't it seeing any mail? Do I need to make an Inbox directory and tell postfix to deliver there? From reading the docs, having the delivery into the main maildir directory should be okay, but I might be mis-reading. Any thoughts would be much appreciated.. Thank you, -Micah

[Dovecot] Permission denied changing to mail directory
by Chris Hogan 28 Aug '05

28 Aug '05

I have 3 domains using one mail server. I've set the dovecot mail directories to be /mail/mail/%d/%n When someone logs on, dovecot attempt to navigate to the domain directory first & we get a permission denied, and we get no further. Its very odd because (a) it was working up until 16:50 on Thursday & (b) the directories now have 777 access. Each user is (at present) a separate unix user & the directories are owned by root & have a file group of mail. I would have thought that the 777 access would have been enough. I don't know what we did on Thursday evening, but any ideas about how to fix the permissions problem? Chris

[Dovecot] Dovecot and Active Directory Authentication
by Dave Smith 28 Aug '05

28 Aug '05

First off, sorry if this has been asked before - I have looked, honest. Is it possible to get dovecot to authenticate users against active directory, treating the AD as a plain ldap server? I have this working with cyrus saslauthd. Currentlt I get a long delay (30 seconds or so) then * BYE Disconnected for inactivity. All I get in the maillog is imap-login: Disconnected: Inactivity [::ffff:127.0.0.1] I am using dovecot-0.99.11-2.EL4.1 on CentOS 4. If anybody has got this to work then please let me know - otherwise I will be forced to use Cyrus........ Cheers Dave Smith

[Dovecot] Dovecot Delivery Bug
by Marc Perkel 27 Aug '05

27 Aug '05

Ran into an interesting bug in Dovecot delivery. A friend forwards an email to me as an atachment. When I receive it - it comes in as two separate messages. One is the forwarding message which is empty, and the other is the original message that was forwarded but it comes in as if I had got the email directly. If I use exim to deliver the message to the mailbox it works. But when exim pipes the message into dovecot deliver it gats split. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

Right ? Yes, at least in 1.0-alpha1/stable, so I guess the same for 0.99. Dovecot can authenticate via mysql directly, of course (but I've never done it, so don't ask me how!)

Probably a good idea to upgrade to dovecot-1.0-stable or dovecot-1.0-alpha1 (0.99.11 is pretty old, even 0.99.14 is pretty well obsolete).

[Dovecot] Wiki of dovecot.conf file
by Tim Schaefer 26 Aug '05

26 Aug '05

What would be extremely helpful is a really clean explanation of how to set up connections for MySQL. It would have to start with basic information and some real-world examples that make no assumptions, and clearly spell it out without confusion. In fact good examples reduce the need to subscribe to mailing lists and ask dumb questions! The current assumptions in the docs to date are that somehow non-geeks and those of us who have learned far more about email servers than we ever wanted to will somehow "get it" without decent examples. This has got to be the biggest problem using Dovecot. I've tried just about every pop-server I can find and I am about to give up on Dovecot if I can't get the connection to MySQL to work. I just want decent pop server that understands Maildir, now that I went through Cyrus SASL hell and got that working--again with incredibly poor documentation. And I don't give a rats-ass about IMAP, just need a pop server. Maybe IMAP later, for now just a pop server that understands Maildir and comes from open source. I'm using Postfix but it shouldn't matter. So far I've tried the following pop servers: nupop-1.3.9 -- can't compile qmail-1.03 -- a f**ing nightmare cyrus-imap/pop -- poor-to-no docs for pop server -- another nightmare vm-pop3d-1.1.6 -- works only on mbox flexpop-1.0.1 -- no docs , doesn't compile popular-1.5.5 -- docs are too sketchy for installation, too complicated and doesn't work I thought Dovecot would be the last one I have to screw with, but maybe I'm wrong... Thanks, Tim
