I'm a perl programmer, and it has all been very educational, so please bear with me :) I was stuck because the domain name was not interpolated into the Maildir path[0], when using the configuration recommended here: http://wiki.dovecot.org/ QuestionsAndAnswers#head-153aa253aff40951a05cf238da4245b1cc1a4665 It turns out that the answer is really simple. You don't need to supply a default_mail_env parameter with vpopmail and dovecot v1.x. Indeed, you shouldn't: the path to the maildir is retrieved from vpopmail and if you specify default_mail_env then it will be used in place of that correct value. Also, it will be used wrongly, as there is also an interpolation bug, and %d isn't replaced correctly. The code in passdb-vpopmail and userdb-vpopmail works perfectly, by the way: the login email address[1] is parsed correctly, the vpopmail hookup is correct, and the vqpasswd struct that is returned by vpopmail_lookup_vqp contains all the right values. eg (these are debugging-for-dummies lines that I've scattered everywhere): > dovecot: Jan 17 22:51:42 Info: auth(default): * > vpopmail_verify_plain: now vpop_user = sysadmin, vpop_domain = > spanner.org, request->user = sysadmin(a)spanner.org, vpw->pw_dir = / > home/vpopmail/domains/spanner.org/sysadmin in the callback method I got this tab-separated auth_reply_stream: > dovecot: Jan 18 00:30:01 Info: auth(default): userdb_callback str: > USER 2 sysadmin uid=7797 gid=2109 home=/home/ > vpopmail/domains/spanner.org/sysadmin but I still saw these lines later: > dovecot: Jan 18 01:31:46 Info: imap(sysadmin): maildir: root=/home/ > vpopmail/domains//sysadmin/Maildir, index=/home/vpopmail/domains// > sysadmin/Maildir, control=, inbox= I became suspicious, and tested with nonsense values in default_mail_env: sure enough i got the same thing. During the userdb stage we have the correct path to the maildir, but later on we see a different value derived from the nonsense configuration I've just entered. I guess that we're getting the initial value from vpopmail and try the same thing but with no default_mail_env entry at all. It works perfectly. I say some new words I have learned from my wife. I don't know where the failure lies, but I can tell you that the 'user' value passed to get_var_expand_table (which comes from getenv ("USER")) contains only the first part of the email address. That's probably not the intention, because get_var_expand_table then tries to split it on @. As it happens the home-directory value is passed to get_var_expand_table as the expansion for %h, so this works too, in a completely redundant way: default_mail_env = maildir:%h I've tested this with an new tarball of 1.0.beta1 and it works fine - with the configuration change - so if this all sounds sane to you then I'll update the wiki. best, will [0] under vpopmail the maildir for the address brian(a)domain.com usually lives somewhere like: /home/vpopmail/domains/domain.com/brian/, [1] in order to disambiguate usernames, vpopmail has you log in with your full email address as the user id. dovecot would therefore need to split the email address and interpolate the fragments into the maildir path to get to the right place. however, the vpopmail password file also specifies the maildir for each user, which i guess is what dovecot is using now.

[Dovecot] new configure-option --disable-index
by Marten Lehmann 22 Jan '06

22 Jan '06

Hello, I experimented with dovecot the whole evening yesterday and the mailserver worked fine since there haven't been that much users connecting to it. I'm using dovecot 1.0.alpha5 as pop3 and pop3s server. The maildirs are mounted through NFS and since there is no nfslockd running I disabled mmap in the config and told dovecot to use dotlock. Also I experienced, that dovecot was much faster when using one login-process per connection instead of sharing them throughout several connections. Sharings seems to be a greater performance problem (bottleneck) than additional fork()s. However, under normal load at business time the server load increased to a value that made it impossible to download emails without timeouts, so we switched back to tcpserver/qmail-pop3d for pop3 and only kept dovecot for doing the pop3s part. Dovecot is really fine, but it still isn't NFS ready. Especially when using dovecot as pop3 only this index-stuff must be disengageable. What is the use of generating a complex index file for hundreds of messages, that will be deleted in the next step after downloading them? But the index is also a problem when using IMAP over NFS. Access to the files is too slow, so the connections keep hanging around and the i/o waiting value is raised to a maximum which slows down the whole machine. It simply doesn't make sense to build and update an index every time the maildir is accessed (which is very cpu and timeconsuming), while search operations (the only moment when the index is actually used and not just heavily updated) don't affect even 1% of all IMAP calls (and such a command doesn't even exist for pop3). I would be much obliged if you could create an option called "--disable-index" in the configure-script or something like "disable-index = yes" in dovecot.conf that makes dovecot ignoring existing index files and doesn't care for related operations, so NFS should work much faster and IMAP search would simply parse the files directly instead of looking in the index. I would really appriciate this very much and I'm absolutely sure, that a lot of people beside me are waiting for this. Regards Marten

[Dovecot] core files
by jared 22 Jan '06

22 Jan '06

Hey all: Was playing around with kill -11 on dovecot processes to see which ones would dump core and which ones wouldn't. If ulimit is correct dovecot and dovecot-auth will dump. If you perform the recommended (Set mail_drop_priv_before_exec = yes in config file) step, imap will also dump core. But I'm unable to force imap-login to dump core. I'm curious if this is possible without the linux kernel patch that's recommended on http://dovecot.org/bugreport.html. (BTW tried the patch on my 2.4.18 kernel but the patch had all kinds of errors.) Thanks, Jared DeMott

[Dovecot] 1.0 beta 1 feature request: passwd-file vs. prefetch
by Matthias Andree 22 Jan '06

22 Jan '06

Greetings, it appears as though 1.0.beta1 doesn't support "userdb prefetch {}" with "passdb passwd-file { arg=/etc/mailpasswd }" even if the latter contains all necessary information. Is this planned for a future version or would the benefits be too small to justify that? Another idea: can userdb prefetch {} fall back to retrying the passdb entries to see if they come up with useful information? -- Matthias Andree

[Dovecot] Mail.app message numbering for deleted messages
by jcn-dovecot＠pith.org 22 Jan '06

22 Jan '06

I'm having a strange problem that appeared when I upgraded from .99something to 1.0alpha3 and then disappeared for a while and then re-appeared when I upgraded to 1.0alpha5. I am using mbox and IMAP in Apple's Mail.app to read my mail. When I delete a message in Mail.app, the message gets marked as deleted in the spool and it disappears from the mail listing in Mail. However, the message number does not change until I either manually flush the deleted messages through mail, or I go offline which deletes the messages from the spool. I have mbox_lazy_writes set to 'no' but this didn't seem to have any effect on the behavior. I never saw this type of behavior with UW-IMAP either, which is what I migrated from. Thanks.

[Dovecot] in a major jam... authentication
by tallison1 22 Jan '06

22 Jan '06

I was upgrading my debian box and managed to upgrade my dovecot installation at the same time. I wasn't planning on it, but it came along just the same. I took some notes on what I thought I needed to change, but apparently it wasn't enough. I've been running this for quite some time now with pgsql authentication and it's been one of those nice applications that always behave themselves. Until now. I can connect to the database. But I always fail the authentication. From the logs I'm coming in on a PLAIN authentication and failing on "password mismatch" The database hasn't changed the password in years. The database stores the password as (I believe) an md5 encryption of the real password. Whatever it is, it is definitely encrypted in the table. What I had in my configuration file was something like this: disable_plaintext_auth = no (this was marked as the default and I enforced it in the new file) auth_mechanisms = plain auth_passdb = pgsql:/etc/dovecot/dovecot-pgsql.conf auth_user = root login = imap I have updated the configuration as follows: dovecot-pgsql.conf 'driver = pgsql' 'default_pass_scheme = PLAIN-MD5' ( I tried changing this to PLAIN but it didn't help ) dovecot.conf protocols = imap disable_plaintext_auth = no protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } passdb sql { args = /etc/dovecot/dovecot-pgsql.conf } userdb passwd { } user = root } I'm not sure what to try now, all I know is that my IMAP server is just dead and I'm unable to get the authentication working again. I can't find much that says how to set this up again and am reluctant to just start trying stuff.

[Dovecot] INBOX as either mbox or Maildir
by Tom Alsberg 22 Jan '06

22 Jan '06

In Dovecot 0.99, I recall somewhere I read it was possible for INBOX to be both a Maildir and an mbox in the same configuration (either automatically detected, or depending on the existence in a different location). Perhaps I was wrong, I'm not sure. Any way, I now became interested in this sort of setup: Most users have their spool an mbox in /var/mail/<username>, and then they (or their MUA) have to move read mail from there to ~/mbox or something like that (a state in which users use the spool as a long-time storage space is unacceptable, and we have measures to avoid it). However, for those that will access their mail only via IMAP, it will be easier to set in .forward or something like that automatic delivery directly to their mailbox - some Maildir in their home directory (there can then be a link from /var/mail or /var/maildir or whatever to there), which will contain both read and new messages. In such a case one would want INBOX to be that main mailbox. Would it be possible to set Dovecot to either automatically detect whether /var/mail/<username> is a Maildir or mbox (which relates to my interest in mixing maildirs and mboxes in one namespace which I have written about several months ago) or to configure several options for INBOX with the first one found used?

This is what's happened: I had original made an rpm with checkinstall, so I removed the dovecot user, so that a new install would set it up with the expected UID and GID, and removed the rpm. My 'bright' idea was that I would install the official Fedora 0.99.14, then install 1.0bet1 over it. I had been assured earlier that it would install over the executables, so it seemed reasonable. I got 0.99.14 on, but could not find the dovecot.conf.example or dovecot.conf to check paths, which worried me a bit, so I thought that if I attempted a login it would give me errors that would define a path. For the first time ever, it logged in! What's more, I can see my imap directories on another box. The only dovecot.conf that I know about is the copy that was in /home/anne. What do you think is happening? If all is working I will leave well alone. This is to be a temporary mail server while I do an upgrade. I don't want to do any more work on it than I need to, because I will be doing it over again, for a permanent install, on the upgraded box in a week or so.

[Dovecot] beta1: how to use quota plugin???
by Jeff A. Earickson 20 Jan '06

20 Jan '06

Hi, After searching gmane.mail.imap.dovecot on the topic, and wiki.dovecot.org, I'm still clueless on how to use RFC 2087 quotas in dovecot with the quota plugin. How come no wiki doc? My setup: Solaris 9, mbox format. Both the filesystem for INBOXes (/var/mail) and the user's home directories have filesystem-based quotas imposed. For example: % quota -v joeblow Disk quotas for joeblow (uid 20737): Filesystem usage quota limit /export/home 955 298000 302400 (where indices and mail folders go) /var/mail 530 151200 204800 (where joeblow's INBOX lives) If joeblow connects via dovecot IMAP, I want our webmail code (horde/imp) to tell him his disk quotas to keep him out of trouble. Horde/Imp (2.2.5) has quota code that says it works with Courier imap. Dovecot is supposed to be Courier compatible. How do I get the quota info out of Dovecot and down to Horde/IMP?

hi i downloaded dovecot-1.0.beta1.tar.gz, did a rpmbuild -ta dovecot-1.0.beta1.tar.gz (which uses the dovecot.spec from the tar.gz), and got the following: Making install in quota make[3]: Entering directory `/usr/src/gimre/rpm2/BUILD/dovecot-1.0.beta1/src/plugins/quota' make[4]: Entering directory `/usr/src/gimre/rpm2/BUILD/dovecot-1.0.beta1/src/plugins/quota' mkdir -p -- /usr/lib/dovecot/imap /usr/lib/dovecot/lda mkdir: cannot create directory `/usr/lib/dovecot': Permission denied mkdir: cannot create directory `/usr/lib/dovecot': Permission denied make[4]: *** [install-exec-local] Error 1 make[4]: Leaving directory `/usr/src/gimre/rpm2/BUILD/dovecot-1.0.beta1/src/plugins/quota' make[3]: *** [install-am] Error 2 so everything did compile alright, but it has some problems with installing the plugins. and i dunno why it tries to create those directories in the root directory. of course i'm compiling it as a non-root users, so it doesn't have any write permissions. and it normally shouldn't have to do an install in directories other then buildroot. so what's the catch? if i disable from the src/Makefile.in to not compile the plugins, everything works fine, i got a nice rpm file. i'm on Fedora Core 4. any help would be appreciated. thx.

[Dovecot] dovecot lda with sendmail
by Michael Surette 18 Jan '06

18 Jan '06

I'm trying to set up dovecot's deliver program as the lda for sendmail. I seem to need a config file for it '/etc/dovecot-deliver.conf'. Is there any documentation for this configuration file and it's contents? sendmail will call it under the recipient's uid, and all it has to do is drop the message into the proper maildir as defined in /etc/dovecot.conf and update the indexes.

[Dovecot] still strugling

Hi all, After I posted yesterday, I'm still struggling with dovecot 1.0beta1 I installed it on openbsd with no problem. But I can't get it to authenticate plaintext on Unixware. I had to add two include files <sys/types.h> and <sys/mkdev.h> in compat.h because minor and major where undefined on unixware. I doubt that could fail... What's wrong with that conf: ## Dovecot 1.0 configuration file # '#' character and everything after it is treated as comments. Extra spaces # and tabs are ignored. If you want to use either of these explicitly, put the # value inside quotes, eg.: key = "# char and trailing whitespace " # Default values are shown after each value, it's not required to uncomment # any of the lines. Exception to this are paths, they're just examples # with real defaults being based on configure options.

Shared namespaces are meant for user-owned mailboxes which are # shared to other users, while public namespaces are for more globally # accessible mailboxes. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. default_mail_env does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. #separator = / # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox. This is in same format as # default_mail_env, which is also the default for it. #location = # There can be only one INBOX, and this setting defines which namespace # has it. #inbox = yes # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension or shown in LIST replies.

However the first few times a mailbox is opened, Dovecot hasn't # yet figured out what client needs, so it may not perform optimally. If you # know what fields the majority of your clients need, it may be useful to set # these fields by hand.

Doesn't work with NFS. # # You can use multiple locking methods; if you do the order they're declared # in is important to avoid deadlocks if other MTAs/MUAs are using multiple # locking methods as well.
