[Dovecot] auth error using director

[Dovecot] Dovecot 2.0, mysql and quota

Hello all, I have some troubles to make the quota_check working with dovecot 2.0. My config is the following: postfix, dovecot as lda, mysql as virtual mailuser backend, and postfixadmin for the mailuser administration.

[Dovecot] rsync.dovecot.org
by Timo Sirainen 01 Jul '11

01 Jul '11

Looks like at least some people still want to rsync their own local dovecot.org mirrors, so I've now added rsync support back. Use rsync.dovecot.org as the host. You can rsync: hg dovecotweb dovecotwiki dovecotwiki2 and mbox files of mailing list archives: dovecotmail dovecotnewsmail dovecotcvsmail So for example: rsync -az rsync://rsync.dovecot.org/dovecotweb dovecotweb

[Dovecot] NFS mail storage
by Daniel L. Miller 30 Jun '11

30 Jun '11

The parameters listed for nfs installations (mmap_disable, doctlock_use_excl, mail_nfs_storage, mail_nfs_index) - are they necessary for data integrity, and/or do they compensate for NFS latency and improve performance? My understanding is the indexes are a critical part of a dbox storage, but on the other hand having local indexes is a major performance consideration. Is maildir a "better" choice under NFS than dbox? -- Daniel

[Dovecot] dovecot, mdbox and indexes
by Angel L. Mateo 30 Jun '11

30 Jun '11

Hello everybody, We are updating our old dovecot 1.1 servers to 2.0. We have a farm os servers, with users in nfs filesystems and indexes in local fs. Mail is stored in maildir format. We don't warrant that a user is always directed to the same server, although our load balancer sends all request from one IP to the same server (during a session time with a inactivity timeout). This is the second scenario described at http://wiki2.dovecot.org/NFS. We are now trying to migrate to the third scenario and using mdbox. As an intermediate step, we have configured this second scenario, but with indexes in NFS filesystems. The configuration is: * mmap_disable = yes * dotlock_use_excl = no * mail_nfs_storage = yes * mail_nfs_index = yes * lock_method = fcntl (we have also tried with dotlock) This configuration works without any problems with few users, but with high load, we have a lot of lock timeouts error like: Jun 29 10:24:04 myotis34 dovecot: imap(mpm): Error: Timeout (180s) while waiting for lock for transaction log file /home/pas/01/014601/maildir_indexes/.INBOX/dovecot.index.log These errors cause a corrupted index and we have to manually delete the user's index so he could read his mail again. So we are planning to configure the third scenario. In this configuration, we don't have any problem during our tests if we use maildir format. But if we use mdbox one, we have problems when we have to change the final server for the server (We allways send the user to the same final server, but sometimes, if the server is down, for example, this is not possible). The tests we have done (with POP) are: * I connect to "my" server. There's no problem. I have my mail. I delete a mail. * I connect then to a server that have no index for me. The only problem is that the previously deleted mail appears again. * I connect then to a server with an outdated index: this is the problem. I have only the messages in that outdated index. The mail received since then has disappeared (although I could receive new mail). How could I solve this problem? Is this really a problem? Should I use a shared storage for indexes? What is the best configuration for a high availability service? -- Angel L.

Re: [Dovecot] [Urgent] Email Retrieval from remote servers doesn't use Dovecot

So far I have managed to download emails from Inbox and Sent folder. All the downloaded emails go to single folder 'new' from 'Maildir' directory. Please tell me if there is a way (configuration) to download emails in respective folders. "getmail" appears to support delivery to an arbitrary Maildir folder. See "getmail" documentation. You might want to read up about Maildir to see how it works. In particular you need to know that mail is delivered to a directory "new" (the delivery process involves the directory "tmp", but the message isn't considered delivered until it reaches the directory "new"), but gets moved to a folder "cur" when the Maildir is looked at. So mail could be in either directory "new" or "cur". (The design of Maildir attempts to address various problems, and only partially succeeds, and in other cases makes things worse than they would have been otherwise. But despite its flaws, it still has some strengths, such as reliability, (relative) simplicity, wide support, and the ease by which a message store can be queried/interrogated.) > Also, is there any need for Dovecot now? As I see it, I have managed to download emails from remote servers in maildir format using getmail. How and why would Dovecot fit in? Will Dovecot (via deliver and sieve) assist in segregated email storage (i.e. INBOX in 'new', DRAFTS in '.draft/new' etc). It might be handy to have Dovecot installed as it would mean you could "see into" the mail folders using an IMAP client such as Thunderbird. This will probably make it easier to get a handle on which messages are in which folders than trying to look in the Maildir directories directly. IMAP has a special folder called "INBOX" which appears as the Inbox in most IMAP clients. Under Maildir, in the default location, INBOX can be found at ~/Maildir/{new,cur,tmp} Other folders are mapped into directories, for example the mail folder "Sent" will appear at ~/Maildir/.Sent/{new,cur,tmp} Nested mail folders are flattened into a single directory level in the filesystem, with the folder levels separated by dots, so the mail folder "Projects/PJ1" will appear at ~/Maildir/.Projects.PJ1/{new,cur,tmp} (The above is the default way for Maildir to work. However, Dovecot can be configured to map IMAP folders into Maildir directories in other ways.) Bill

[Dovecot] Problem accessing Dovecot mailing lists via IMAP
by William Blunn 30 Jun '11

30 Jun '11

I recently tried to look at the Dovecot mailing lists through an already-configured IMAP profile, which had worked fine in the past. But it failed saying that the authentication method was not supported. http://www.dovecot.org/mailinglists.html says: "You can get access to the IMAP archives by using *dovecot.org* as the hostname, *anonymous* as the username and an empty password. It's also possible to use ANONYMOUS authentication mechanism if your client supports it (few do)." I noticed that my e-mail client was configured to use the server "imap.dovecot.org", so I changed it to "dovecot.org". But it still complains that the authentication method is not supported. I am using Thunderbird 3.1 over Windows 7 64-bit. Thunderbird was configured for "Password, Transmitted insecurely" (and this option was not working). I have tried the other authentication options available in Thunderbird. "Encrypted password": Does not work; same problem "Kerberos / GSSAPI": Does not work; same problem "NTLM": Does not work; same problem Any ideas? Bill
