[Dovecot] IMAP error after login
by Nicolas STRANSKY 28 Aug '03

28 Aug '03

Hello, I'm having a slight problem with Dovecot (0.99.10-0.rc2, on Debian woody). When using mozilla 1.4, there is an error message from the mailer just after login, but nothing in dovecot logs. "Alert The current command did not succeed. The mail server responded: Error in IMAP command UID: Too long argument.." How could I fix this problem ? Thanks, -- Nico J'ai une panne de micro et les parasites me brouillent l'écoute

[Dovecot] Chrooting the Mail processes
by Bert Koelewijn 25 Aug '03

25 Aug '03

Hello! Could somebody give some feedback on this configuration: - OpenBSD box with local ssh users. - /home directory mounted with nosuid,noexec. - postfix dropping mail in /home/username/mail/INBOX, with the UID/GID of the user. - dovecot: valid_chroot_dirs = /home default_mail_env = mbox:/home/%u/mail/:INBOX=/home/%u/mail/INBOX Are there any obvious ways for a local user to help dovecot escape the chroot jail? How can I check that dovecot is REALLY using /home as chroot jail for the imap process? Thanks! Bert Koelewijn

[Dovecot] Docs on the wiki
by Bob Hall 25 Aug '03

25 Aug '03

I went to the Dove Wiki page and added a couple of docs. There's a DoveWikiMainPage link at the top of the first page now. Click on that and the next page has links to the two docs. Someone who knows more than I do about wiki formatting should make this look good. The two docs are for Dovecot/OpenLDAP installation. The first is detailed instructions and the second is a cheat sheet. You don't need to contact me if you find errors; just click "Edit this page" at the bottom. Anyone who wants to use parts of my docs to use in documenting other types of installation should feel free. There's no mention of copyright policy, but I assume everthing is GPL copyleft. Bob Hall

[Dovecot] Postfix and Maildirs
by Steve Sloan 24 Aug '03

24 Aug '03

Hope someone can help me with this as I am presently stuck I am setting up a new server with Dovecot 0.99.10, Redhat 9.0, Postfix, Amavisd-new and maildir's in the users home drive. I am using Netscape mail 7.1 as the main client to access the mail store via imap which works fine and various other imap clients can access the maildirs Ok as well. The problem is when Postfix delivers a message is insists on making a second Maildir directory in the user's home drive and put the message in there. The Maildir's are being created automatically ie. I didn't use maildirmake. Even if I delete one of the Maildir's it just gets recreated again. ie. this is the test user's home drive drwx------ 10 test2 test2 4096 Aug 23 20:53 Maildir drwx------ 6 test2 test2 4096 Aug 24 11:05 Maildir This is the Maildir that the clients are using and being accessed by Dovecot drwx------ 10 test2 test2 4096 Aug 23 20:53 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 23 19:58 cur -rw------- 1 test2 test2 5 Aug 23 19:58 .customflags drwx------ 5 test2 test2 4096 Aug 23 19:59 .Drafts drwx------ 2 test2 test2 4096 Aug 23 19:58 .INBOX drwx------ 2 test2 test2 4096 Aug 23 19:58 new drwx------ 5 test2 test2 4096 Aug 23 20:15 .Sent -rw------- 1 test2 test2 29 Aug 23 20:13 .subscriptions drwx------ 5 test2 test2 4096 Aug 23 20:11 .test drwx------ 2 test2 test2 4096 Aug 23 19:58 tmp drwx------ 5 test2 test2 4096 Aug 23 20:11 .Trash and the other one which Postfix user's drwx------ 6 test2 test2 4096 Aug 24 11:05 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 24 11:05 cur -rw------- 1 test2 test2 5 Aug 24 11:05 .customflags drwx------ 2 test2 test2 4096 Aug 24 11:05 .INBOX drwx------ 2 test2 test2 4096 Aug 24 11:05 new drwx------ 2 test2 test2 4096 Aug 24 11:05 tmp This one has no index files and looks just like a courier Maildir For Postfix main.cf I have set home_mailbox = Maildir/ and /etc/dovecot.conf default_mail_env = maildir:/home/%u/Maildir Hope this make sense to someone Steve -- _____________________________________________ LanSol Computers 283 Sir Donald Bradman Drv.

[Dovecot] Three oddities
by Bob Hall 24 Aug '03

24 Aug '03

FBSD 4.8, Dovecot-0.99.10 1) I have mail accounts for people who use Macs and Windows, so their mail is stored on a Unix box where they don't have accounts. When their mail comes in, it is stored in /var/mail/<accountname>. When I was setting this up, I used my own Unix account for testing, and that works fine. But for the other mail accounts, which don't correspond to Unix accounts, I want to give ownership of the /var/mail/* files to another account that doesn't have my privileges. However, no one can access their mail unless I own their files. As long as I own all the /var/mail/* files, everything works fine. But if I shift ownership to another account, users can log on to Dovecot but attempts to access an IMAP folder return an error. >From maillog: Aug 18 16:39:46 kongemord imap(philrodrigues): mkdir_parents(/var/mail/philrodri gues/.imap/INBOX) failed: Permission denied All files and directories in /var/mail/* are in the mail group. I tried adding dovecot to that group, but that didn't help. Since everyone can log on to Dovecot, but can't access their mail unless I own their files, I'm assuming that there's some simple ownership setting that I'm overlooking. But I haven't a clue what it is. Can someone tell me what I need to change? 2) The Macs have Eudora 4.2 installed, and the Win boxes have Eudora 5.1. The Macs can delete mail, put it in the trash, and empty the trash. The Win clients can mark mail deleted, but they can't remove it. The mail stays in the IMAP folder until the same user accesses their mail from a Mac and deletes it. If a user drags a message to another folder, a copy is created in the new folder but the old copy remains in the original folder. I'm not having this problem with Mutt, so it the problem seems to be specific to the Windows verson of Eudora. Is there a fix? 3) We're pulling our e-mail off our ISP's POP server and loading it into Dovecot to allow people to work with their mail from different machines. I'm using getmail to make the transfer. Is anyone else doing POP to IMAP, and how are they doing it? Any suggestions? TIA, Bob Hall

[Dovecot] user database clarification
by Jared 22 Aug '03

22 Aug '03

Hi, this question gets back to a thread I started back on July 8th. (gosh how time flies) I still am not clear on why PAM is not supported for the user database. I'm in an environment that has users both in local flat files (/etc/passwd and /etc/shadow) AND in an LDAP database. Is it possible for this set up to work with dovecot? (both local and ldap users have imap/pop?) I'd prefer to just have Dovecot use PAM for user db and the password database so that I can configure PAM to try both local users and LDAP users. Thanks a lot. -jared

[Dovecot] rawlog change suggestion
by Charlie Brady 21 Aug '03

I find the separate .in and .out files rather difficult to work with. I think it would be more useful if the in/out traffic were interleaved with a prefix to indicate direction, and suffix to indicate continuation, as recordio (http://cr.yp.to/ucspi-tcp/recordio.html) does: <a0002 LIST "" "" >* LIST (\Noselect) ";" "" >a0002 OK List completed. <a0003 SELECT "INBOX" >* FLAGS (\Answered \Flagged \Deleted \Seen \Draft) >* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags + >permitted. >* 18 EXISTS >* 0 RECENT >* OK [UNSEEN 18] First unseen. >* OK [UIDVALIDITY 1055795174] UIDs valid >* OK [UIDNEXT 6741] Predicted next UID >a0003 OK [READ-WRITE] Select completed. <a0004 STATUS "incoming.foo" (RECENT) >* STATUS "incoming.foo" (RECENT 397) >a0004 OK Status completed. <a0005 NOOP >a0005 OK NOOP completed.

[Dovecot] Mozilla dovecot interaction
by Eric S. Johansson 21 Aug '03

21 Aug '03

I think this is more a Mozilla bug but just a heads up the case other people complain. periodically, the Mozilla e-mail client refuses to delete messages. It shows up either as absolutely no action when you press the delete key/button or it shows activity but refuses to perform any other action in that mailbox. Sometimes if you switch to another mailbox and then come back to the mailbox you're deleting e-mail message from, the messages deleted when you re-enter the mailbox. I looked with ethereal and it looks like Mozilla is not sending any imap commands. Hence my assertion that it's a Mozilla problem. The only reason I mention it here is because something about dovecot seems to trigger the problem more quickly. I was seeing this kind of problem before but only after a week or two of uptime in the browser. Now I'm seeing it in just under a week (I think) I've only seen at once but I will keep track for future reference. I got to get me a new client... ---eric

[Dovecot] transitional weirdnesses
by Eric S. Johansson 20 Aug '03

20 Aug '03

1) not reproducible but when it occurred, its stuck: in the early transition to dovecot I would notice occasionally that messages would come up, I would delete them and then something would hang causing a major delay in the (Mozilla) e-mail client's response. When the system responded, I would notice that occasionally there would be an off by one offset between the index of messages and the message displayed. This error would persist until I killed off the index and the dovecot process. 2) very reproducible: after fetching messages from my inbox, there will be a long (30 sec.) delay. Dovecot demon is clearly busy doing something. I do have a large set of filter rules (approximately 150) sorting messages into different boxes. Is this a reason to switch to maildir? 3) just ended up with a message that displayed the entire header. Will look into this more but it's very strange. ---eric

[Dovecot] Squirrelmail and Dovecot folder namespace
by Warren Togami 19 Aug '03

19 Aug '03

I am currently using Squirrelmail and Dovecot with this setting: default_mail_env = mbox:%h/mail/:INBOX=%h/mail/INBOX It works well, however folder subscriptions in Squirrelmail annoyingly end up with "./" prefixes because Squirrelmail refuses to work without overriding the folder namespace. All of my other IMAP clients work fine without setting that option. Squirrelmail's default setting is this: $default_folder_prefix = './mail'; This setting breaks Squirrelmail: $default_folder_prefix = ''; This setting becomes default if you attempt to blank that user's preference: $default_folder_prefix = './'; The end result of this is duplicate entries in .subscriptions, one with "./" prefix and one without. Most IMAP clients handle this by showing all the folders again in a folder named ".", or Mozilla displays all folders twice. =( When I asked one of the squirrelmail developers, he said that this might be a dovecot specific problem. Any ideas? Warren Togami warren(a)togami.com

[Dovecot] Questions
by Alejandro Martinez 19 Aug '03

19 Aug '03

Hi, I'm still figthing with passwd-file, virtual users and permissions. I have created the directory /var/spool/virtual/test and inside I've done a "maildirmake Maildir". I have a couple of questions : I use the same passwd-file for auth_userdb and as auth_passdb. 1) What program can I use to create the userdb file ? What I do now is to use the htpasswd program and then I complete by hand the rest of the fields (uid:group:GECOS:home:shell) htpasswd userdb test password: xxx again: xxx And then vi userdb test@test.com:ssasZXc00P1H6:502:102::/var/spool/virtual/test/:/bin/false <--by hand. I think that if I want to offer virtual mail with imap is very tedious to complete user by user. (If this second question does not fall in this list, then don't answer it) 2) I know that postfix delivers in Maildir format, and when the user is a virtual user, I do the next Modify the virtual file ---> test(a)test.com test.test.com Modify the aliases file--> test.test.com: /var/spool/virtual/test/Maildir postmap hash:virtual postaliases hash:aliases postfix reload but when I do a "echo testing | sendmail test(a)test.com " I receive an error Aug 18 15:32:44 slk90 postfix/pickup[12208]: 95C3717D5C: uid=0 from=<root> Aug 18 15:32:44 slk90 postfix/cleanup[12252]: 95C3717D5C: message-id=<20030818183244.95C3717D5C(a)slk90.equital.lx> Aug 18 15:32:44 slk90 postfix/qmgr[12209]: 95C3717D5C: from=<root(a)slk90.equital.lx>, size=291, nrcpt=1 (queue active) Aug 18 15:32:44 slk90 postfix/local[12254]: 95C3717D5C: to=<test.prueba.com(a)slk90.equital.lx>, orig_to=<test(a)prueba.com>, relay=local, delay=0, status=bounced (cannot append message to destination file /var/spool/virtual/test/Maildir: cannot open file: Permission denied) I'm confused about permissions.

[Dovecot] more transitional joys

well, now that I have moved to dovecot, I'm not getting any spam... in fact, I'm not getting e-mail at all. default_mail_env =mbox:~/IMap2/:INBOX=/var/spool/mail/%u when I first tried to access my inbox, I was told I had permission problems: Aug 14 17:47:22 harvee imap(esj): open(/var/spool/mail/esj.lock) failed: Permission denied Aug 14 17:47:22 harvee imap(esj): file_lock_dotlock() failed with mbox file /var/spool/mail/esj: Permission denied so I changed permissions on /var/spool/mail to 777 as a temporary work around. no luck.

[Dovecot] login w/ IMAP & LDAP
by Bob Hall 16 Aug '03

16 Aug '03

I'm getting imap-login: Internal login failure: bob whenever I try to check mail. I'm new to mail server setup, new to IMAP, and I don't know a heck of a lot about authentication schemes. I've set up Dovecot as an IMAP server on FreeBSD 4.8. I've got OpenLDAP running on the same system. Users will access mail via Eudora on Windows and Macs, so that's how I'm testing. If I try to test Dovecot using IMAP commands via telnet, Dovecot tells me LOGIN BAD Error in IMAP command received by server. I also can't telnet via localhost; I have to specify the host name, so I'm connecting via the host's external interface. I have no problem connecting to localhost on ports not used by Dovecot. So I have two questions: 1) How do I correct my configuration to make login successful? 2) How can I test Dovecot without using an MUA? If I have to use an MUA, I can't distinguish between errors in the MUA and errors in the IMAP server. Thanks for any help with these two. Configuration follows. Eudora: Server configuration: IMAP IMAP Mailbox Location Prefix: /var/mail/bob/Mail Authentication Style: passwords dovecot.conf ---------------- protocols = imap imaps imap_listen = *:143 login_user = dovecot default_mail_env = mbox:/var/mail/%u/Mail auth_userdb = ldap /usr/local/etc/dovecot-ldap.conf auth_passdb = ldap /usr/local/etc/dovecot-ldap.conf auth_user = dovecot dovecot-ldap.conf ------------------- hosts = localhost dn = cn=dovecot,dc=domain,dc=tld dnpass = ********** ldap_version = 3 base = ou=accounts,dc=domain,dc=tld deref = never scope = subtree user_attrs = uid user_filter = (&(objectClass=inetOrgPerson)(uid=%u)) pass_attrs = uid,userPassword pass_filter = (&(objectClass=inetOrgPerson)(uid=%u)) default_pass_scheme = PLAIN slapd.conf ----------------- password-hash {CLEARTEXT} If I change this last to CRYPT (comment out the dovecot-ldap default_pass_scheme and change the slapd.conf password-hash to {CRYPT} and re-enter the password into LDAP), I get the same error. I have no problem accessing the LDAP data from the command line. If I comment out the dovecot-ldap.conf user_filter and pass_filter, I get dovecot-auth: ldap(bob): unknown user I interpret as meaning that the user_filter and pass_filter are necessary. Bob Hall

[Dovecot] joys of transition.
by Eric S. Johansson 15 Aug '03

15 Aug '03

Red Hat 8.0 stock dovecot 99.10 for a variety of reasons, I decided to cut over to dovecot this morning. I extracted all of my mailboxes from mbx purgatory back to mbox purgatory, set up dovecot and proceed to get authentication failures. (am using simple password based authentication either direct or through pam) I turned authentication verbosity on and got: Aug 14 11:51:38 harvee dovecot: Dovecot starting up Aug 14 11:51:46 harvee dovecot-auth: PAM: pam_authenticate(esj) failed: Authentication failure Aug 14 11:51:49 harvee dovecot-auth: PAM: pam_authenticate(esj) failed: Authentication failure Aug 14 11:51:52 harvee imap-login: Aborted login [192.168.0.10] not very informative. I already know that I can't login. So I fire up ethereal and capture the following transaction: * OK dovecot ready. 1 authenticate login 1 NO Unsupported authentication mechanism. 2 login "esj" "no peeking" 2 NO Authentication failed. 3 authenticate login 3 NO Unsupported authentication mechanism. 4 login "esj" "no peeking" 4 NO Authentication failed. 5 logout * BYE Logging out 5 OK Logout completed. hmm no unsupported authentication mechanism. So that means all authentication methods works right? ;-) looking a little further into the configuration, I see instructions to change auth_methods to add plain in front of digest-md5 (or is it digest_md5, both forms are present in the configuration file). No luck. Doing so gives me the following error message: Fatal: Error in configuration file /usr/local/etc/dovecot.conf line 430: Unknown setting: methods so, I'm not sure what to look for. It's probably something simple but googling didn't reveal anything pertinent although it turned up something amusing[1]and dovecot does apply. Suggestions or clues would be welcome. FYI, you probably could use a little bit more detail in the install instructions. For example instructing user to create a dovecot user and group name would be useful as would be a startup/shutdown script for init.d. I also find the SSL configuration lacking. On the other hand, I have enough scar tissue from certificates and mini-CA setups to hate them till the end of time. If I get them working better, I'll document and send it to the list. ---eric [1]http://www.oblomovka.com/eldritch/iag/ob1-5.htm

[Dovecot] Hardlinks in copy
by Andreas Aardal Hanssen 12 Aug '03

12 Aug '03

Hi, Dovecotters. In the Maildir code, dovecot-0.99.10/src/lib-storage/index/maildir/maildir-copy.c, I see that hardlinks are used. It seems that (line 185) if MAILDIR_COPY_WITH_HARDLINKS is exported, then copying is attempted by using link. Having problems reading the source / flow of control, I resort to this list. When a file is linked, the mtime is naturally kept on the destination. This gives the destination message the same internaldate as the original. The destination mailbox would then be likely to get an arrival with an earlier internaldate than its newest message. The IMAP protocol says to bump UIDVALIDITY when this happens. Does Dovecot always bump UIDVALIDITY when messages are copied, or is not the mtime used for internaldate? Best regards, Andreas -- Andreas Aardal Hanssen
