[Dovecot] dovecot-1.0-beta3 in production

Hello there! I've migrated our courier-imap production imap/pop server to dovecot 1.0-beta few days ago.

[Dovecot] Impact of log files on performance
by vmstech 27 Feb '06

27 Feb '06

Hi - im trawling through my config trying to reduce chances of timeouts etc - I use postgres for all the dovecot and exim4 authentication and location of mail directories etc - and found that by eliminating logging (or reducing to almost none) the queries invovled have gone from >500ms to <3ms - Just wondering if I'll get similar performance gains with dovecot (which is set to be verbose as I could) - esp during connection thx Glenn

[Dovecot] Errors
by vmstech 27 Feb '06

27 Feb '06

Hi All I intermittently get these kind of errors when connecting to my beta2 imap dovecot: reported error 0x8004df0b:'Outlook is unable to download folder (null) from the imap email server for account mymailhost.com'. Error the server is unavailable. Receiveing Reported error (0x800CC0F):'The connection to the server was interrupted' While these are from outlook - I often get one simiar to the first one in my evolution clients. Are these things that can be best managed with some sort of configuration change? What might be other possible causes of these (apart from a power cut to the server? thx Glenn

[Dovecot] RHEL4 configuration
by f00bar 26 Feb '06

26 Feb '06

I just installed a new email server using RHEL4. I only want pop3d services, no imap is desired so I modified the dovecot.conf file by changing to "protocols = pop3". All is working fine. However, dovecot requires access to /home/user/mail or the Thunderbird client hangs when attempting to download email. We have a single /home that is mounted by all servers for all users. We do not want the mail server to mount this /home. So I created directories with the usernames in the mail server's /home. This is not desired from a system management perspective. The files dovecot creates in the /home/user/mail directory appear to be for the use of IMAP which we do not use. How do I configure dovecot to not access /home and to not create any IMAP files? Thank you

Hi. I've just compiled dovecot-1.0.alpha5 with mysql support.from freebsd ports (FreeBSD 6.0-RELEASE). It looks like dovecot has problems connecting to mysql. In the log I'm getting: dovecot: Feb 24 16:57:41 Error: auth-worker(default): mysql: Connect failed to (null) (exim): Access denied for user 'root'@'localhost' (using password: YES) - waiting for 5 seconds before retry dovecot: Feb 24 16:57:41 Error: auth-worker(default): sql(facha(a)facha.org.ua,127.0.0.1): Password query failed: Not connected to database dovecot: Feb 24 16:57:44 Info: pop3-login: Aborted login: user=<facha(a)facha.org.ua>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured This is my dovecot-mysql.conf: connect = host=localhost dbname=exim user=root password=qwer default_pass_scheme = PLAIN password_query = SELECT password FROM auth WHERE username = '%u' AND domain = '%d' Exim is working with the same settings on the same machine. I also checked if I can use these settings with mysql console client. I don't know where to look for errors. Is anyone else having this problem? Thanks in advance for your answers.

[Dovecot] index file vs. memory
by Marten Lehmann 25 Feb '06

25 Feb '06

Hello, we have a large base of mailbox users and while pop3-connections are usually closed after the download of all mails, I noticed hundrets of imap-connections kept idle by the users. This is surely according to the idea behind imap, but I'm a bit afraid of overwhelming memory consumption if there are too many imap-connections opened at the same time. Is the index file kept in memory as long as an imap-connection exists, or is it closed as soon as a certain read or write command has finished? Regards Marten

[Dovecot] Dovecot username mapping
by Adam "Fuzzy" Kennedy 24 Feb '06

24 Feb '06

Ok, here's my situation. I currently run IMail 7.x with about 80 domains and nearly 4000 users. I want to switch this to a Linux server. I'm using Virtualmin to manage the users/postfix. I have dovecot working just peachy with the setup, except for one problem. We are an ISP. The easiest thing for us (and our users) is to have them use their full email address as their username. What I need is some way to have Dovecot take a username and map it to the real unix user. Our unix users are created as "username-domain.com" When our users login to our current email system, they enter their username as "username(a)domain.com". I for the life of me cannot figure out how to make Dovecot take "username(a)domain.com" and know that the unix username is really "username-domain.com" Ideas? -Adam "Fuzzy" Kennedy

RE: [Dovecot] IMAP login name conversion

> -----Original Message----- > From: Timo Sirainen [mailto:tss@iki.fi] > Sent: Tuesday, 1 June 2004 9:39 PM > To: Zoong Pham > Cc: dovecot(a)dovecot.org > Subject: Re: [Dovecot] IMAP login name conversion > > What passdb and userdb do you use? Unless you're authenticating from > SQL you probably have to modify the source. Let me explain: My server runs OpenBSD-3.5 and Sendmail. We host few virtual domains. Local accounts have login names in this format: login-domain_abc_xyz For example: joedirt-joedomain_com_au, info-adomain_com, info-otherdomain_com That way login accounts are unique across all the virtual domains. I use the OpenBSD pre-compiled dovecot-0.99.10p2. It is set to use "auth_passdb = passwd" and "auth_userdb = passwd" I can use mutt to access my mailbox via IMAPS with login name format joedirt-joedomain_com_au. Other users use different MUA like Outlook and prefer to login with their email addresses (joedirt(a)joedomain.com.au, info(a)adomain.com, info(a)otherdomain.com) We use squirrelmail for webmail. I modified squirrelmail to automatically convert login name from format of joedirt(a)joedomain.com.au to joedirt-joedomain_com_au. So if users use squirrelmail, they can just login with their email addresses. My question is how to achieve the same thing with other MUAs like Outlook? Do I have to modify dovecot source? Can I use LDAP or SQL instead? Note that we are using Sendmail and prefer it than othe MTA. I have looked at the Wiki, specially the "DovecotOpenLdap" but am still confused. Thanks Zoong

[Dovecot] Old Maildir UW-imap
by Torbjörn Gripp 24 Feb '06

24 Feb '06

Hi all, I'm new in using dovecot and I'm running in a problem, which I cannot solve without hours and hours of work. Maybe there is a solution, which I didn't find with old friend google :_) Here is the problem: We are using an old mailserver (it's running fine for 5 years) with qmail and the old uw-imap server. All users have their grown directories under a home/Maildir folder. All subdirectories are lying under Maildir/sub/sub/sub. Now I want to migrate to dovecot and I have a lot of trouble, cause I cannot find a solution to migrate to the folder structure /Maildir/.sub.sub.sub. It's really difficult cause all the windows users have subdirs like one folder (1945)/a new ö/ and something like that! Any hints?? greetings and sorry for the bad english -- [ t o r b j o e r n g r i p p ] senior systemadministrator opus 5 interaktive medien gmbh grossneumarkt 50 20459 hamburg fon: +49(0)40 350174-439 fax: +49(0)40 350174-404 mobil: 0175 9326096 mailto:gripp@opus5.de http://www.opus5.de

[Dovecot] Server & move to Dovecot
by K Gilpin 24 Feb '06

24 Feb '06

Hi, I a currently running a server which is using uw-imap server which currently has 190 users. I am looking to move the server OS and the imap server to Dovecot Imap Server. We are currently using mbox as the default mail file. I have a couple of questions to ask. 1) Would it be better if we moved to maildirs during the server move? 2) All current mail files are in a directly called /export/home/mail/%username. How would one configure dovecot to use the above path? How points to any good FAQs would be great. Thanks Kevin

[Dovecot] Digest-MD5 and GSSAPI not working in beta3
by Casey Allen Shobe 24 Feb '06

24 Feb '06

I have built dovecot with kerberos support, however am not able to log in using GSSAPI support in my mail client. I receive the following error: SASL(-4): no mechanism available: No worthy mechs found Additionally, Digest-MD5 does not work - I receive an authentication failed (as though I have an incorrect password) if I try to use it. I am using PostgreSQL for authentication, and returning a plaintext password with my SQL query. LOGIN, PLAIN, NTLM, and CRAM-MD5 are all working as expected. I tried making the change shown in Mark Davies' src/auth/mech-gssapi.c patch (posted to the list on 10 February), but it had no effect. Any advice welcome!

[Dovecot] INBOX as Maildir and folders as mbox
by Chris Wakelin 24 Feb '06

24 Feb '06

Hi, I was wondering whether anybody has managed to get Dovecot 1.0 to store INBOX as Maildir and folders as mbox. I've tried something like default_mail_env = mbox:/folders/user/mail:INBOX=maildir:/inboxes/maildir/user:INDEX=/indexes/user but it doesn't seem to work (treats INBOX as mbox). I'm hoping to move some INBOXes from mbox on local disk to Maildir on nicely-mirrored NetApp NFS (or possibly iSCSI) servers for redundancy and better incremental backups. I'm probably doing something silly, or have misunderstood something!
