[Dovecot] User mapping via pam
by Flannery, Andrew 27 Jun '07

27 Jun '07

Hi, I'm trying to change the PAM_USER within a pam module, and observed that dovecot 0.99 does not support this. I then looked at 1.x and found: src/auth/passdb-pam.c:232: /* FIXME: this doesn't actually work since we're in the child process.. */ status = pam_get_item(pamh, PAM_USER, (linux_const void **)&item); if (status != PAM_SUCCESS) { *error = t_strdup_printf("pam_get_item() failed: %s", pam_strerror(pamh, status)); return status; } auth_request_set_field(request, "user", item, NULL); however it appeared to me that the auth process was passing this username to the parent in its response. Is this issue resolved? I compiled and tested mapping the username sso to the user andrew: Jun 27 13:38:45 itsrv dovecot: auth-worker(default): pam(sso,10.x.x.x): lookup service=imap Jun 27 13:38:45 itsrv dovecot: auth(default): auth(sso,10.x.x.x): username changed sso -> andrew Jun 27 13:38:45 itsrv dovecot: auth(default): client out: OK 1 user=andrew Jun 27 13:50:57 itsrv dovecot: auth(default): master in: REQUEST 1 19761 1 Jun 27 13:50:57 itsrv dovecot: auth(default): passwd(andrew,10.x.x.x): lookup Jun 27 13:50:57 itsrv dovecot: auth(default): master out: USER 1 andrew system_user=andrew uid=1001 gid=1001 home=/home/Andrew Also, is this behavior dependant on me setting blocking=yes for "passdb pam" in dovecot.conf? (for this test It was set) Thanks, Andrew Flannery

[Dovecot] ?? Error: child 1064 (imap) killed with signal 4
by Benton Haynes 27 Jun '07

27 Jun '07

After noticing a commit to the HG repository, http://hg.dovecot.org/dovecot-1.0/rev/f88b1e225be5 about, " We didn't update last_output timestamp with long fetches, causing Dovecot to idle-disconnect the client." I chekced out the latest from the DOVECOT-1.0 repo, and built again. Unfortunately, this problem still exists. Login simply disconnects. Any help, anyone? -- Ben

[Dovecot] LogicMail for Blackberry and Dovecot
by Rick Romero 27 Jun '07

27 Jun '07

FYI - I just had a great interaction with the developer of this software. LogicMail for Blackberry is a true IMAP/POP client for Blackberry, which wasn't working correctly with Dovecot's IMAP. I merely posted in the sourceforge forums and got a VERY fast response with a working fix. http://logicmail.sourceforge.net/ Unfortunately I'm not a Blackberry user, but I know IMAP clients are hard to find. So I can't comment on it's usability or features, but I thought I'd give it a little press for his quick response :) Rick

[Dovecot] 1.0.rc28 released
by Timo Sirainen 27 Jun '07

27 Jun '07

http://dovecot.org/releases/dovecot-1.0.rc28.tar.gz http://dovecot.org/releases/dovecot-1.0.rc28.tar.gz.sig Still a bit more fixes. My coding TODO list is again empty. Unless something special happens in the next few weeks, I'll still make rc29 with the documentation included and v1.0 will be released April 13. * deliver + userdb static: Verify the user's existence from passdb, unless allow_all_users=yes * dovecot --exec-mail: Log to configured log files instead of stderr * Added "-example" part to doc/dovecot-sql-example.conf and doc/dovecot-ldap-example.conf. They are now also installed to $sysconfdir with "make install". + When copying/syncing a lot of mails, send "* OK Hang in there" replies to client every 15 seconds so it doesn't just timeout the connection. + Added idxview and logview utilities to examine Dovecot's index files + passdb passwd and shadow support blocking=yes setting now also + mbox: If mbox file changes unexpectedly while we're writing to it, log an error. + deliver: Ignore -m "" parameter to make calling it easier. + deliver: Added new -n parameter to disable autocreating mailboxes. It affects both -m parameter and Sieve plugin's fileinto action - mbox: Using ~/ in the mail root directory caused a ~ directory to be created (instead of expanding it to home directory) - auth cache: If unknown user was found from cache, we didn't properly return "unknown user" status, which could have caused problems in deliver. - mbox: Fixed "UID inserted in the middle of mailbox" in some conditions with broken X-UID headers - Index view syncing fixes - rc27 didn't compile with some non-GCC compilers - vpopmail support didn't compile in rc27 - NFS check with chrooting broke home direcotry for the first login - deliver: If user lookup returned "unknown user", it logged "BUG: Unexpected input" - convert plugin didn't convert INBOX

[Dovecot] Public Namespace and ACLs with pure virtual users
by Marc Delling 27 Jun '07

27 Jun '07

hi! i would appreciate to have some comments on my below scenario: # from the config userdb static { args = uid=vmail gid=mail home=/vmail/%d/%n } namespace public { separator = / prefix = All/ location = maildir:/vmail/%d/all/Maildir:CONTROL=~/Maildir/control/ all:INDEX=~/Maildir/index/all inbox = no hidden = no } namespace private { separator = / prefix = location = maildir:~/Maildir inbox = yes hidden = no } # end config the public namespace is also the maildir of the user "all@mydomain". a sieve skript is dropping mail for all@mydomain to the appropriate maildir within this maildir/namespace (e.g. .Support/) first of all: this works to some point but is such a configuration valid? can a public namespace be the maildir of a user? if a new mail for all@mydomain comes in, all subscribed users (of this domain) can view it and it is marked as /Seen individually. the important feature to me: the /Seen flags are managed per user as configured in the public namespace now the problem: the whole mail system runs with one uid/gid and virtual users, which has the effect that some user can delete mails in the public namespace or drop mails into it, create folders etc. this is not wanted. i wanted a read-only public namespace. so i decided to use acls. as namespace prefixes are ignored i needed to create them globally. my first try was: /etc/dovecot/acls/Support: owner lrwstiekxa authenticated lr which lead to the result that other users than all@mydomain cannot manipulate the public namespace at all, including setting their /Seen flag. that was the first surprise to me as i thought this flag would be managed seperately in the users homes. after a (very short) thought i came to this (allow setting the /Seen flag for others): owner lrwstiekxa authenticated lrs which lead to another unexpected result: the /Seen flag is now set globally. if one user marks a mail /Seen, it is /Seen for all other users too. where is the problem? except for the iso/osi layer 8 problem i am aware of... marc

[Dovecot] set maildir and directory default for deliver?
by Mark Edwards 26 Jun '07

26 Jun '07

I asked this question in a more detailed post, with no response, so I'm going to ask point blank. Is there a way make dovecot's deliver use default mailbox and directory settings? I'm thinking of the mail_location parameter, which deliver seems to ignore. Thanks! -- Mark Edwards

[Dovecot] APPEND fails
by Dirk Müller 26 Jun '07

26 Jun '07

hi list, i wrote a small tool in java which transfers all mails from one imap-server account to another imap-server account using the javax.mail API. when i use cyrus as source and destination imap server everything is fine. when i use dovecot as destination server occasionally exceptions occur when appending the mails. i was not able to see what's really going wrong so i used wireshark to get the imap command that fails: A23 APPEND INBOX.MYSUBFOLDER () "14-Mar-2007 14:20:45 +0100" {0+} A23 NO Append aborted. this is easy to check via telnet, always the same error. i'm not sure why the javax.mail API uses the "{0+}" but somehow it occurs every now and then. sending this command to a cyrus imap server does not fail. any idea? is this a javax.mail problem? thanks and best regards, dirk
