[Dovecot] Chrooting the Mail processes
by Bert Koelewijn 24 Aug '03

24 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 24 Aug '03

24 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

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.
