[Dovecot] couple questions about dovecot
by Raan Young 18 Nov '12

18 Nov '12

I am attempting to migrate an ancient IMAP server to Dovecot 2.0.9 running on CentOS 6.3, while trying to minimize the impact on users. Most are using Outlook. I have everything working, but have run into a couple of problems, neither horrible, but both weird. It started when I noticed Outlook shows the .subscriptions file in the folder listing. I figured out a way to prevent that (see below), but then decided to attempt the same tactic to move the .imap index structure out of the folder tree and ran into an interesting side-effect. The .subscriptions issue would seem to be a bug, since the documentation I found implies Dovecot should be hiding it from list requests - as it does for the .imap index structure. I made a workaround by using the below mail_location setting. This puts the .subscriptions file above the imap folder structure and hence outside the list scope. mail_location = mbox:~/imap:INBOX=~/mbox:CONTROL=~:INDEX=~/.imap You'll note I have also moved the .imap index. This works, but the full path to the index files has extra layers of .imap. For example, if a folder tree of imap/A/B/C/D exists, where D is the actual mbox format message file, then the index files are stored in .imap/A/B/C/.imap/D. Don't know if this is a bug or I'm misunderstanding something. Can you provide any insight or better solutions for either issue? Some clients are also using iPhones and/or roundcubemail for web access. Those do not have the .subscriptions issue. Raan

[Dovecot] multiple users to same e-mail account with ldap authentication
by Marco Gatti 14 Nov '12

14 Nov '12

Hi, I was looking for a particular case of dovecot configuration I cannot find anywhere. Is there a way dovecot can authenticate via ldap different windows 2008 AD users that have access to the same e-mail account (like user authorization in ms exchange)? For example I want to extend AD schema to let users have 10 email accounts (with multiple domain support). If they are private accounts I think there is no problem at all. But if I want two or more users to access the same mail account what happens? Can I do it with dovecot? Or should I create AD groups and add members to that, to let user access the same mail account? Cheers -- Marco

Re: [Dovecot] IPhone wont delete IMAP messages from dovecot mailbox
by tibby＠tibby.hu 14 Nov '12

Hello! I've got dovecot running with postfix. Have virtual users under vmail folder. When I connect with outlook, I can read, delete messages. When I sign on with webmail, also can delete messages, Mutt is working as well on the mail server, can delete messages. Once the message is deleted it moves to the trash. Works as it supposed to. But on Iphone, when I add a mail user, got the mailbox synced with IMAP I can see the INBOX, but when I delete a message, get this error: "Unable to Move Message The message could not be moved to the mailbox Trash." http://www.netchimp.co.uk/webdesign/wp-content/uploads/2011/12/iphone_unabl… What causing this problem? Please Help.

[Dovecot] Dovecot 2.1.10
by Ralf Zimmermann 14 Nov '12

14 Nov '12

Hi all, I've a problem with dovecot-2.1.10. At time we use dovecot-1.2 without zlib. We setup a new server with dovecot 2.1.10. After syncing the emails everything looks fine. But if we use zlib plugin all new emails have no content. There are a lot of "Error: Maildir filename has wrong S value" log entrys. So we have compiled dovecot-2.0.18 and we use exactly the same configuration. Everything works. What can be our problem with version 2.1.10? Greets Ralf

[Dovecot] dovecot lost mail! Cause?
by Lukas Haase 14 Nov '12

14 Nov '12

Hi, After using dovecot for several years now, today happend something which makes me really feel unconfortable: An email received was just not delivered properly, or, is lost! The mail (from an external server) was sent to two local mailboxes, user1 and user2. user1 received the message but for user2, it *magically* disappeared. MTA is exim4 which definitely processed the messages and handed over to dovecot deliver: 2012-11-12 07:28:21 1TXnVG-00053I-GD SA: [...] id=8644593.887351352701 685934.JavaMail 2012-11-12 07:28:21 1TXnVG-00053I-GD => user1 <user1(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD => user2 <user2(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD Completed Also, the log of dovecot tells that the mail should have been stored: Nov 12 07:28:21 mail dovecot: deliver(user1): sieve: msgid=<8644593.887351352701685934.JavaMail>: stored mail into mailbox 'INBOX' Nov 12 07:28:21 mail dovecot: deliver(user2): sieve: msgid=<8644593.887351352701685934.JavaMail.orbitz>: stored mail into mailbox 'INBOX' user1 received the mail but user2 not. Since user2 is myself, I *know* that I did not accidently delete any mail or something like that. It was just never received! Disk space is 3GB left, so enough. So I grepped the whole Maildir of user2 for the message ID. There is only one match in the dovecot.index.cache and within that, the most important data of the mail (Message ID, Date, Sender, Receiver, Subject) appears. But apart from that, not a single file! Is there hope to ever find out why what was going wrong here? It feels me veeeeeeeeery unconfortable because from now on I can never be sure any more that all my mails are really received :( :( However, as I said, my mail system processed maybe millions of messages the past 8 years. Although, I can not be sure if that was the case ... :( And help greatly appreciated! Luke PS: Dovecot version 1.2.15 (Debian 6.0.6) with Maildir backend on local harddrive. No NFS, nothing which can go wrong ... PPS: Original log files, just named replaced for privacy.

[Dovecot] Dovecot newbie (migrating from qmail)
by Ajai Khattri 13 Nov '12

13 Nov '12

Ive been using qmail+vpopmail+courier-imap for many years but its time to retire that server so I thought this might be an opportunity to see how I could use Postfix and Dovecot to provide the same services. Im running Dovecot 2.1.9 and Postfix 2.9.4. I have spent a few days reading through some of the docs on the wiki (there's doesn't seem to be any large overview of Dovecot concepts or books so bear with me). Im thinking something simple like passwd-file setup would suffice for me. I want to use completely virtual users. Id like to store mail under /home/vmail/$domain/$user. I think Ive figured out how to do that. But how do I create the maildir? I understand the need to have a mail directory but also a directory for things like sieve - how to specify that? Im thinking the structure would be something like: /home/vmail/$domain/$user/mail <-- mail stored here /home/vmail/$domain/$user/ <-- sieve and other sundry store here Or should the sieve stuff also be under its own folder alongside the maildir? Is it possible to have a separate passwd file per domain? It is possible to combine password and userdb files into one per domain? (I prefer to keep all files related to each domain in its own folder). Also would like to configure Postfix to use dovecot-sasl and I want to use dovecot-lmtp for deliveries. Any good docs / example on those? Later on, I think I want to integrate some kind of virus and spam filtering (amavisd and maybe dspam - anybody used those? would I configure Postfix to handle that or dovecot-lmtp?) Im sure Ill have more questions as I get more complicated but baby steps for now. -- Aj.
