[Dovecot] quota-command?
by Marten Lehmann 08 May '05

08 May '05

Hello, if you log in at hotmail.com, gmx, lycos or yahoo, you can see something like "using 1.4mb of 250mb total". Is there any IMAP command to check to current quota usage? Our webmail-interface will not have access to the filesystem to summarize the size of each file, so an IMAP-command would be great. I don't know if this would be a new feature or just part of the Maildir++ quota-system, that is not yet supported by dovecot. Regards Marten

[Dovecot] Migrating from courier-imap to dovecot
by Odhiambo Washington 08 May '05

08 May '05

Hello Gang, I am new to dovecot and the only reason (so far) I would like to use dovecot, and in production with 12k+ users, is the fact that it's supposed to be faster and less of a resource hog. Now, sometimes I am really good at reading the documentations but it sometimes happens that one overlooks something. I did read the migration notes three times! My users are in /etc/passwd and I am running dovecot in IMAP only mode. I did put default_mail_env = maildir:~/Maildir in dovecot.conf, then for one user, I did the following: cd ~wash/Maildir cp courierimapsubscribed .subscriptions # Then I edited to remove "INBOX." cp courierimapuiddb dovecot-uidlist The permissions are right, but when I login as this user, I don't see all the folders that had been there before when he was using courier-imap!! When I login to the web interface (we use Squirrelmail) and go to the Folder options, I can't see any folders to subscribe to either! Now my questions: 1. What am I overlooking?? 2. Does someone have a script that can be used to automate the copying of courierimapsubscribed to .subscriptions and that of courierimapuiddb to dovecot-uidlist, and the editing to remove the "INBOX."? I am sure I really don't have to reinvent the wheel, no? Meanwhile I am hitting google, while waiting for your answers.

[Dovecot] How to check for keywords in IMAP store?
by Steffen Kaiser 08 May '05

08 May '05

Hello, I'm checking my way to migrate from Courier to Dovecot. Wiki says that "there's currently no easy way to migrate them [the keywords]". Frankly, I lack the information to check if some client is using keywords at all. More importantly, is it OK to assume that when SELECT INBOX returns no \* in OK [PERMANENTFLAGS ...] that the IMAP server does not allow keywords at all? [BTW: Is there a searchable mail archive of the Dovecot list?] Bye, -- Steffen Kaiser

[Dovecot] SquirrelMail IMAP protocol errors?
by Schettino, John Charles 08 May '05

08 May '05

I use Squirrelmail to filter messages, and it's doing this: raw log in: A009 UID SEARCH CHARSET ISO-8859-1 ALL Header X-Spam-Level {4} **** A010 LIST "" "spam" raw log out: * SEARCH A009 OK Search completed. * BAD Error in IMAP command : Unknown command. * LIST (\NoInferiors \Marked) "/" "spam" A010 OK List completed. it goes on like that in the log for every filter. What exactly is the BAD Error there, and is it something I can fix?

[Dovecot] Setting location for indexes
by dovecot.7.signal11＠spamgourmet.com 08 May '05

08 May '05

We have NFS-mounted user directories which cause significant problems with stale file handles: dovecot: IMAP(uid): fstat() failed with file /home/uid/mail/.imap/INBOX/dovecot.index.log: Stale NFS file handle (a) why can't it just close the file and re-open ? (b) is there a way to specify with the 'default_mail_env' (or in some other way) the location of **only** the indexes (and let dovecot autodetect all else?). I have already tried 'mmap_disable = yes', but that does not solve the problem, and if I set 'default_mail_env = INDEX=/var/spool/mail/INDEX/%u', I get errors like: IMAP(uid): Failed to create storage with data: INDEX=/var/spool/mail/INDEX/uid I don't want to specify mbox:~/mail/ or mbox:~/Mail/, because some users have one and some the other.

I'm using one of the stable 1.0 releases for 184 accounts on Gentoo Linux on Sparc. I too am seeing the message header/body mismatch in Thunderbird.

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Multiple Logins - Single Mail Account
by Net Cerebrum 04 May '05

04 May '05

I have a mail account which needs to be accessed by 4-5 people simultaneously through IMAP. As of now I have configured it on the respective clients using the same username and password so we have multiple people accessing the same account through their mail clients simultaneously and it is working flawlessly. Is this alright or can it lead to some problems or corruption of data later ? What is the best way to allow multiple people to access a single mailbox for read as well as write operations ? Thanks,

[Dovecot] Error in rename uidlist while fetching through pop3
by James Berry 03 May '05

My dovecot server seems to randomly begin giving errors to pop3 users who try to fetch their email. Once this begins, they see no more new mail, though the mail is in cur. Running: dovecot-stable 20050501, Mac OS X 10.3.9 Log entries like this: May 2 19:35:18 caddy dovecot: pop3-login: Login: kim [24.22.16.169] May 2 19:35:18 caddy dovecot: POP3(kim): rename(/Users/kim/Maildir/ dovecot-uidlist.lock, /Users/kim/Maildir/dovecot-uidlist) failed: Input/output error May 2 19:35:18 caddy dovecot: POP3(kim): file_dotlock_replace(/Users/ kim/Maildir/dovecot-uidlist) failed: Input/output error Is this a known problem, and/or is there a known way to recover from such a situation? I'm managed to throw out the uidlist, but that means they get a whole dump of new mail. -jdb

[Dovecot] How to try dovecot-lda
by Joakim Verona 02 May '05

02 May '05

Hello, I'm interested in trying the dovecot-lda with sieve support. What would be the proper way to test it? I'm currently using a Fedore core 2 server, with spamassassin and procmail. To get the same effect with dovecot-lda, would I put a line like this in my .forward? spamassassin|dovecot-lda I'm just guessing, so please correct me if im wrong. Im thinking of setting up a separate mail account and copy my mail there to test the ported procmail to sieve recipies also. -- Joakim Verona www.verona.se

[Dovecot] disabling indexes?
by Marten Lehmann 02 May '05

02 May '05

Hello, I recently had the problem, that an index was corrupt. Thus, messages haven't been listed (talking about POP3), but still remained in the filesystem. As there is no SEARCH-command in POP3, dovecot didn't notice that the index is corrupt and didn't rebuild it. The problem is, that a user can't delete messages through POP3 which aren't listed by dovecot. If the maildir size increases, the arrival of new messages will be blocked because the mailbox is full. And the user has no chance to delete it. Regards Marten

[Dovecot] Blank lines in mailboxes
by Jakob Curdes 30 Apr '05

30 Apr '05

Hello, we use dovecot on a regular basis. Sometimes I end up with a user telling me he does not get mail. When I look after the problem, I always find leading blank lines in the mbox file. We are using postfix with dovecot and amavisd as spam scanner. Amavisd never accesses the mbox files directly so this can be ruled out. I suspected procmail but now it happened also with accounts where no procmail is active. I found only a list thread where this happened always, i.e. it was a configuration error. (Meaning the mailbox was correct but dovecot would not read it). Here ist is only occasionally and therefore hard to track . Does anybody have the same problem or has hints to a solution ? We are running postfix 2.1.4 and dc 0.99.10.6 ; just now I am upgrading to pf 2.2.2. and dc 0.99.14. Yours, Jakob Curdes

[Dovecot] Fresh Dovecot Install
by GPL 29 Apr '05

29 Apr '05

Working on an RH9 box. Did not use yum. Downloaded the "dovecot-stable-latest.tar.gz". Uncompressed it, downloaded and installed gcc. Ran the following: ./configure make sudo make install Seemed to have done its thing. I'll admit I am not well versed in using "make" or compiling anything. When I install I usually use yum on fedora machines. This one being an RH9 machine I have plugged yum into the fedora legacy project and it did not let me install dovecot via yum. So I opted for this route. Regardless, if I run 'which dovecot' I see "/usr/local/sbin/dovecot" However now I do not seem to be able to see it run. I get nothing when I: rpm -qa | grep dovecot ps aux | grep dovecot service dovecot status SO AM HAVE MISSED SOMETHING! Is there another script I need to run? Suggestions welcome. Thanks, George

[Dovecot] dovecot 0.99.xx to 1.0-stable how-to?
by Rich West 28 Apr '05

28 Apr '05

I realize that there have been some big changes in features and configuration file settings between 0.99.xx and 1.0-stable, so when I went to perform an upgrade on our testing server, I carefully combed through the configuration files and matched up everything I could. I fired up dovecot-1.0-stable and was pleased to see that it was happily running. I attempted to connect to it, and discovered that it wasn't listening to any ports.. then I realized that the app had crashed due to a typo in the config file (oops). Fixed that, started it up, and it was happily running and listening. However, it wouldn't authenticate any users.. Backing down to the 0.99.14 version that we had installed allowed for authentication (against ldap) to work just fine.. Is there anything that I should be looking for within the dovecot-1.0-stable that is dramatically different in regards to user authentication? -Rich

I don't know enough to say either way. Maybe I'll take a closer look after I've finished delving into Sun's RBAC. As for the code changes, from memory the UID checking stuff is all in the one place ( in 0.99.14 it seems to be src/lib/restrict-access.c ). I'm not sure about 1.0... we'll move to that when we can have custom flags :) -- Curtis

[Dovecot] cutting everything after @
by Juraj Bednar 27 Apr '05

27 Apr '05

Hello, I am migrating one server to dovecot. The only problem is, that users have logins with @domain as part of their user name. I want to use pam auth (for other reasons, if only for dovecot, I would use mysql, but I need the same password db to be used for other services, like samba). Is there a way to allow this type of login? Just cut everything beginning with @. I can change the source code, but then I don't get nice automatic upgrades. Or can this be done easily with PAM? Thanks, Juraj.

[Dovecot] Shared mailboxes and accessing MailDir not through IMAP
by Steffen Kaiser 27 Apr '05

27 Apr '05

Hello, I'm testing Dovecot that is part of Debian/sarge (v0.99.14-1). So far so good. I have migrated some mailboxes for testing with success and seems that everything works fine. One thing I do not figure out is, what to do about shared mailboxes, which are the very reason of searching for an alternative IMAP server, The Wiki states that there is some sort of shared mailboxes, based upon symlinks. Well, but since which version actually?? The Changelog stops at 2003-11-08 21:12 ? What I need is a mailbox (maildir) for a contact address (not a real shared mailbox, but several users shall be able to read a mail and delete it after processing). For this, one needs write permission to the mails therein only, the MDA takes care of to make the mails readable for the group. It would be good to see, if somebody had answered a mail already, but that's not required. What I tried is this: I setup all Unix-permissions of the folders (. cur new tmp: u=rwx,g=srwx) and their parents (u=rwx,g=x). Then I placed a symlink into the maildir of all users. Each user caches the INDEXes into an individual /var/ directory, not in the maildirs themselves. (BTW: I wonder why I need to give the group write permission to the base directory '.'). The mailbox shows up and is read-write. Now I wonder, what impact I'm to expect here? Esp. "The only problem is that currently everyone's message flags would be shared as well." (quote from a message of a thread taken from the Wiki) Then there is http://dovecot.org/pipermail/dovecot/2003-March/001113.html the third item will apply to my situation, I guess. MailDir is (sort of) expected to be read by mutt directly, for instance. Because the mailboxes are located within the users home directories, some of them do this. Do this item mean that Dovecot is NOT expecting that mails are deleted in any other way than through itself? Otherwise Dovecot would find a change in the mailbox and rebuilt the index file regardless whether the change had been originated by another IMAP client or by directly manipulating the maildir. Bye, -- Steffen Kaiser

[Dovecot] local users + virtual domains
by Micha Silver 27 Apr '05

27 Apr '05

I'm redesigning our mail server which holds several hundred mailboxes - most are local system users and some are virtual domains that we host. I understand that the 1.0x stable release allows for multiple auth mechinisms, so that I could use both PAM for local users and a passwd-file for the virtuals. If I want to stick with 0.99x can I mix and match in a single passwd-file the username/passwd for both local and virtual users? In dovecot.conf I'd have something like: default_mail_env = maildir:%h/Maildir auth-userdb = /etc/dovecot/passwd-file auth-passdb = /etc/dovecot/passwd-file then in passwd-file I'd enter: # local users localuser1:<passwd>:501:501::::: localuser2:<passwd>:502:502::::: ... #virtual domains virt1(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir virt1(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir ...
