[Dovecot] 1.0beta to latest and greatest?
by Charles C 05 Mar '12

05 Mar '12

dear dovecot users, This is my first post and with a rather embarassing question. To soften the question up I just want to say I've been very pleased with Dovecot thus far and its low maintenance requirements - perhaps to pleased! I am running an ancient version of Dovecot, version 1.0.beta9. Do I risk corrupting indices etc by upgrading in one go to 2.1.2? Thanks for your input. Charles

[Dovecot] BlackBerry will not setup my POP3 email, all other mail clients fine
by Ian Solecki 05 Mar '12

05 Mar '12

Hello, hoping someone here might be able to help me or at least point me in the right direction. My company recently (last week) moved to a new dedicated server for website and email hosting. It is a fairly run-of-the-mill Linux machine running cPanel and Dovecot (with the BlackBerry Fastmail service enabled) as a mail server. When we first set up the server, I was able to create a mailbox, access it via any desktop mail client, webmail, AND by setting it up as a basic POP3 account on my BlackBerry. Mail was running fine to and from the BlackBerry, no problems. I deleted that account from my BlackBerry as it was a test account, and went to add my actual account but was unable to do so. Received the "Cannot log in. Verify your email address, user name and password. If the error persists, contact (my domain name)" message. I tried the test account that had been running successfully and sending/receiving emails not minutes earlier, and it would not set up either. I have since tried multiple accounts on multiple BlackBerry devices (different models) on multiple carriers on several of my different domains (all of which point to the same server, of course), to no avail. Yet, any of these accounts still work flawlessly in any desktop mail client (Outlook, OE, Thunderbird, iPad, iPhone, etc). Also, any of these BlackBerrys work flawlessly with any other mail server. The username to log in to these mailboxes is not standard, it's mailboxname+ example.com if the email address is mailboxname(a)example.com and the mail server is mail.example.com. So, I know I have to access the "Advanced Settings" in BlackBerry email setup in order to put this username in. Still, no effect. So, there is something wrong with how mail SETUP works (not sending/receiving, though that may also not work, I have no way of knowing now) between RIM and my server, and it's something that has changed since the server was set up a week ago. My carrier(s) are clueless, my dedicated server provider (Lunarpages) is clueless. Can anyone help?

[Dovecot] doveadm -A stops processing at first uid<first_valid_uid
by Joseph Tam 04 Mar '12

04 Mar '12

I would like to run various doveadm commands that involves all (mail) users like doveadm expunge -A mailbox Trash savedbefore 30d but any doveadm command that uses "-A" to iterate through all users will stop processing at the first account with UID<first_valid_uid. doveadm(sysdaemon): Error: user sysdaemon: Couldn't drop privileges: Mail access for users with GID 5551 not permitted (see first_valid_gid in config file, gid from userdb lookup). doveadm(sysdaemon): Error: User init failed doveadm: Error: Failed to iterate through some users However, these accounts are system accounts (locked password, no shell) and are in userdb to provide UID<->name mapping for utilities like ls, chown, etc. There are various workaround like iterating manually, or setting first_valid_uid to zero, or even reordering users to put all system accounts at the end, but is there a better way to do this?

[Dovecot] Multiple namespaces seems to be used at the same time
by Steve Campbell 04 Mar '12

04 Mar '12

I've just converted from an old Centos 3 box to a Centos 6.2 box. I've switched from UW-imap to dovecot in the process. In my configurations, I've placed the multiple namespace sections as suggested by the "Backward compatability" part of the wiki. I use mbox since I mostly copied the home directories from the old to the new server. On some of the clients, it appears that the client is using multiple namespaces at the same time. When they view their subscribed folders, they see multiple "mail" folders instead of just the single "mail" folder under their home directory. The .subscription files are more than likely not correct (haven't looked yet, but will fix them as a user calls), but should this ever happen? I'm also sure the client's prefix isn't set since the old system never required it and there are just so many other things that are required right now on this conversion. Speaking of prefixes, I'd like to get the default of "" (nothing entered) to work for the majority of the users to avoid having to add this to the multiple users we have. Hopefully, by going through each user's home directory and copying the old .mailboxlist to a new .subscriptions file and ensuring the imap folders are in ~/mail will do this. Does this sound resonable? Thanks for any help. The learning curve is getting less steep, but it's still a ways off to the top of the hill. steve campbell

[Dovecot] doveadm fetch prints duplicate results in 2.1
by Christoph Bußenius 04 Mar '12

04 Mar '12

Hi, when the private namespace has "prefix = INBOX." and you use doveadm fetch to search for "mailbox INBOX", then it prints every message twice: # doveadm fetch -u testuser 'mailbox uid guid' mailbox INBOX mailbox: INBOX uid: 1 guid: 1757c403a4ec4d4fbf040000463889b5 mailbox: INBOX uid: 1 guid: 1757c403a4ec4d4fbf040000463889b5 Without "prefix = INBOX." in the configuration, the messages are only printed once. In 2.0, they were never printed twice. doveconf -n # 2.1.1: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-35-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = acl mail_uid = vmail namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { mail_plugins = acl imap_acl } Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.055 <> Boltzmannstr. 3 <> Garching

[Dovecot] 2.1.1: Incorrect quoting of RFC 2822 personal parts in ENVELOPE data

[Dovecot] LIST-STATUS issue

04 Mar '12

Looked at the hg commits since 2.1.1, but didn't see anything that was exactly on-point to this... UNSEEN counts seem to be broken when done in a LIST-STATUS call. I see this, for example: >> Timestamp: Thu, 01 Mar 2012 10:55:47 -0700 [...] C: 3 LIST "" (INBOX IN.dovecot) RETURN (STATUS (UNSEEN)) S: * LIST () "." "IN.dovecot" S: * STATUS "IN.dovecot" (UNSEEN 0) S: * LIST () "."

I am using imapproxy for these connections, so all access are happening in the same Dovecot access. michael

[Dovecot] directly addressable public folders issues
by Tom Fernandes 04 Mar '12

04 Mar '12

Hi, I would like to have an address info(a)example.com whose mails are stored in a public folder. I also want certain users to be able to create sieve-filter-rules and subfolders. From what I understand it's a good idea to have a separate location for home and for mail_location. For my normal accounts I have: home = /var/vmail/<user> mail_location = ~/Maildir Is there a way to have the same for public folders? This are my current settings: namespace public { separator = / prefix = public/ location = maildir:/var/vmail/public subscriptions = no } user_attrs = homeDirectory=home=/var/vmail/%$, =mail=maildir:~/Maildir The LDAP-homeDirectory-attribute for info(a)example.com is "public/.info" Like this an incoming mail is stored below /var/vmail/public/.info/Maildir which is good. The MUA seems to read to read from /var/vmail/public/.info though. How can I make the MUA read from /var/vmail/public/.info/Maildir instead? And in case this works - is it possible to have only certain users modify the sieve-rule for this public folder or do I definitely need a passdb-entry for info(a)example.com? Modifying scripts via commandline is not an option... I'm using dovecot 1.2. regards, Tom Fernandes
