[Dovecot] Vexim with LDA delivery
by Chris Wopat 09 Mar '07

09 Mar '07

No support help needed, just a success report having Dovecot integrate with Vexim (exim with web based frontend and sql db): http://silverwraith.com/vexim/ Just wanted to forward some configs to the list if anyone finds them useful. I just switched from vexim's normal "virtual_delivery" to "dovecot_virtual_delivery" so I could use sieve, which works nicely with Horde. This is mostly as described on the wiki: http://wiki.dovecot.org/LDA I'm using maildirsize in my case. There were a few things that had to be done to get it to work with quotas, I thought I would just spell it all out for anyone reading this list in the future: I can add stuff if anyone would like to the wiki, some of these items are elsewhere in the wiki, I wanted to ask before I put a full page up for integration with Vexim in particular. Should I do this, or just throw bits and peices where they seem relevant? This was on FreeBSD, hence the /usr/local/etc/ stuff. Exim's 'configure' file: ================================ virtual_domains: #file_transport = virtual_delivery file_transport = dovecot_virtual_delivery virtual_domains_catchall: #file_transport = virtual_delivery file_transport = dovecot_virtual_delivery dovecot_virtual_delivery: driver = pipe command = /usr/local/libexec/dovecot/deliver -d \ $local_part@$domain message_prefix = message_suffix = delivery_date_add envelope_to_add return_path_add log_output user = mailnull dovecot-sql.conf: ================================ driver = mysql connect = host=HOSTNAME dbname=vexim user=vexim password=PASSWORD default_pass_scheme = CRYPT password_query = SELECT crypt as password FROM users,domains \ WHERE users.username = '%u' AND users.enabled = '1' \ AND users.type='local' and domains.enabled='1' \ AND domains.domain_id = users.domain_id user_query = SELECT pop AS home, 26 AS uid, 26 AS gid, \ CONCAT('maildir:storage=', quota*1024) AS quota \ FROM users WHERE username = '%u' AND enabled = '1' Mostly complete dovecot.conf (much of this is obvious, but it's easier than piecing things together from various mailing lists posts/docs): ================================ mail_location = maildir:%h/Maildir first_valid_gid = 26 last_valid_gid = 26 protocol lda { mail_plugins = quota } auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = mailnull group = mail } } } plugin { quota = maildir } ================================ --Chris

I'd like to download a complete mail archive so that I can browse for problems concerning Mulberry. Is this possible, or can I only get them in monthly gulps? Cheers, Terry. --

[Dovecot] Dovecot vs Couir-IMAP
by Erdenebat Gantomor 09 Mar '07

09 Mar '07

I'm the beginner for IMAP/POP3 servers. I'm starting to use Dovecot. But I'm confusing between Courier-IMAP and Dovecot. Anyone tell me some quick tips regarding this issue. What's the better and what's the worst thing comparing these two IMAP/POP3 servers? I think the Dovecot is good enough for security and performance issue over Courier. Is it right? And how about the feature comparision? -- Best regards, Erdenebat Guntomor/ /mailto:RkLogin@gmail.com

[Dovecot] global_script_path and virtual users
by Joan 09 Mar '07

09 Mar '07

We have a big installation with postfix + dovecot + sieve. Now we would like to create a "junk" folder in every customer inbox so they can discard the spam by they own. We are planning to user global_script_path = /etc/dovecot/dovecot.sieve Where /etc/dovecot/dovecot.sieve is: require "fileinto"; if exists "X-Spam-Flag" { fileinto "Junk"; } My question is, will the script find the users in our database? And how, will it be using the lda configuration? I have been for weeks looking for this in the wiki and couldn't find it anywhere. I promise I'll put it in there if I find the clue :)

Re: [Dovecot] Problems with different mail clients
by Nuno Miguel Neves 09 Mar '07

09 Mar '07

Hello, all. I thing I solved my problem... I just changed dovecot.conf to include the default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u which is disabled by default. Now, apparently, I can access my inbox from both my pocket and my Vista Mail. Than you all and hope this helps someone else. :) ----- Original Message ----- From: Nuno Miguel da Cruz Neves To: dovecot(a)dovecot.org Sent: Thursday, March 08, 2007 7:23 PM Subject: Problems with different mail clients I use dovecot as my imap server, and everything is ok. I used an IMAP client from Windows XP (Outlook Express) as well as Pocket PC (Windows Mobile 5) and webmail. The problem is that I recently used Windows Vista and its imap client (Windows Mail), and problems began. From the Windows XP machine, all is ok, but from the Pocket PC a weird thing happens: When I first configure the client, in the Received Items, it shows all items correctly, but then, when starting to donwload, they simply disappear. All other folders are OK. Problem is just in inbox. I thing (although my tests were not exaustive) that deleting the .imap folder solves the problem, but I just can't understand why, because it is recreated again... Any help?

[Dovecot] "ldap_result() failed: Can't contact LDAP server" log messages
by Mike Brudenell 09 Mar '07

09 Mar '07

Greetings - I', continuing to build a test system that, at present, only I have access to. It is running Dovecot 1.0rc24. Here's the output of a "dovecot-n"... # /usr/local/etc/dovecot.conf log_path: /logfiles/mail/live/dovecot protocols: imap ssl_cert_file: /usr/local/etc/ssl/certs/imapservice-bundle.crt ssl_key_file: /usr/local/etc/ssl/private/imapservice-private.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_process_per_connection: no login_greeting_capability: yes mail_location: maildir:/mailstore/%1u/%u/Maildir:INDEX=/var/dovecot/ index/%1u/%u:CONTROL=/var/dovecot/control/%1u/%u mail_debug: yes mmap_disable: yes maildir_copy_with_hardlinks: yes mail_log_prefix: %Us(%u)[%p]: imap_client_workarounds: delay-newmail outlook-idle namespace: type: private separator: / inbox: yes auth default: mechanisms: plain login cache_size: 1024 cache_ttl: 600 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890 username_format: %Lu passdb: driver: ldap args: /usr/local/etc/dovecot-ldap-passdb.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap-userdb.conf We are using LDAP for the passdb and userdb. The oddity is that even on a quiescent system (Dovecot started from scratch, but no connections being made to it) we are seeing these messages being logged, apparently every 5 minutes: dovecot: Mar 09 11:09:44 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server dovecot: Mar 09 11:09:44 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server dovecot: Mar 09 11:14:45 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server dovecot: Mar 09 11:14:45 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server dovecot: Mar 09 11:19:45 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server dovecot: Mar 09 11:19:45 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server I'm guessing there are two log entries each time because of separate connections being used for the passdb and userdb. The LDAP server *is* available throughout. I'm wondering if Dovecot is trying to hold the connection open but, after a timeout of 5 minutes of inactivity, the LDAP server is closing it and causing Dovecot to log this message. If this is indeed the case then I guess on a production server these message will be rarely if ever seen. Obviously I'd prefer not to have such worrying-sounding log entries appearing. (And if my guess is right then they're slightly misleading: the LDAP server *can* be contacted!) Any thoughts?

Hi, We're new to dovecot and like what we see so far, but Google doesn't seem to have much on this error message. What are the likely causes? Kind regards, Larry Vaden, CoFounder and CEO Internet Texoma, Inc. We Care About Your Connection The Market Leader In Texomaland Since 1995
