[Dovecot] Having a problem with mbox/inbox
by Nick Le Mouton 11 Apr '07

11 Apr '07

Hi, I've just installed dovecot on a RHEL 4 server. I'm using postfix as my MTA. Everything seems to work well when I have a home dir for the user, but I don't like to clutter up my /home/ dir with dirs for users that will never use them (other than mail). Is there no way to just use /var/mail/user (I think in mbox format?). I have no interest at this time of using IMAP, this is purely for POP3. Thanks Nick

[Dovecot] error creating subfolders
by John Harper 10 Apr '07

10 Apr '07

I'm running rc31 and I've come across a weird little error in creating subfolders that's only apparent in a specific situation. I recently moved our entire campus from UW to dovecot, and as part of that migration, and following the wiki, I have some namespaces: ##default namespace namespace private { separator = / prefix = inbox = yes } #for backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } which absorb the typical configuration previously used wherein the email client had the imap server folder set to "mail/" or similar, and which still remains on most clients. All of this works perfectly fine, and all users see their mail folders properly. Currently everyone is still in mbox format, and as far as I can tell, users can also create email folders without problems (ie single files in the file system containing messages). But one user discovered that it does not work to create folder containers (ie directories in the filesystem) that would contain other email folders, no matter how one appended / or checked the right box (or having me add the tb-extra-mailbox-sep client workaround -- they're using Thunderbird). Their client config still had mail/ as the server imap directory, and when I cleared that out, then everything worked perfectly. So it's a bit weird that everything works fine with the namespaces, except the one operation of creating the subfolder.

[Dovecot] Dovecot 1.0rc30 message ownership set as root mail
by Mel Llaguno 10 Apr '07

10 Apr '07

I've compiled the latest release candidate of dovecot and I am encountering a strange problem when mail is delivered. I have my installation configured to use Maildir. When messages arrive, they are placed in the correct user directory, but the ownership for individual messages is set to root and the group set to mail. This prevents these messages from being displayed in my client. The error message logged is as follows: dovecot: Apr 08 13:11:08 Error: IMAP(mel): open(/home/mel/Maildir/cur/_d2F.eyKGGB.mjolnir:2,) failed: Permission denied The file permissions for the message are as follows: -rw------- 1 root mail 1805 2007-04-08 13:02 _AqG.VxTGGB.mjolnir:2, I also noticed that the log file in the root Maildir also has the same ownership assigned (not the user's uid/gid). Unless something has changed in dovecot.conf, this behavior is somewhat unexpected. I've included my config file in case there is something obvious that I am missing: base_dir = /var/run/dovecot protocols = imaps protocol imap { listen = imap.domain.com ssl_listen = 0.0.0.0:993 imap_client_workarounds = outlook-idle delay-newmail } disable_plaintext_auth = yes shutdown_clients = yes log_path = /var/log/dovecot.log ssl_disable = no ssl_cert_file = /etc/ssl/certs/imap.domain.com.crt ssl_key_file = /etc/ssl/certs/imap.domain.com.key login_dir = /var/run/dovecot/login login_chroot = yes login_user = dovecot login_process_per_connection = yes login_processes_count = 8 login_max_processes_count = 32 verbose_ssl = yes mail_location = maildir:/home/%u/Maildir:INBOX:/var/mail/%u mail_full_filesystem_access = no mail_save_crlf = no verbose_proctitle = yes max_mail_processes = 128 maildir_copy_with_hardlinks = yes mmap_disable = no lock_method = fcntl umask = 0077 auth default { mechanisms = plain passdb shadow { args = /etc/shadow } userdb passwd { args = /etc/passwd } } If anyone could help clarify this behavior, it would be greatly appreciated.

[Dovecot] "TLS handshake" errors, frozen IMAP
by Ben Beuchler 10 Apr '07

10 Apr '07

Another new issue has cropped up with my rc1 -> rc31 upgrade: This morning, right around the typical morning email surge, Dovecot stopped accepting new IMAP connections. I didn't get a chance to do much troubleshooting and a restart of Dovecot fixed it. The only thing I've been able to find in the logs is a bunch of entries like this one: Apr 10 09:11:36 cliff dovecot: imap-login: Disconnected: rip=150.253.80.90, lip=150.253.10.10, TLS handshake Apr 10 09:11:36 cliff dovecot: imap-login: Disconnected: rip=150.253.80.208, lip=150.253.10.10, TLS handshake Apr 10 09:11:37 cliff dovecot: imap-login: Disconnected: rip=150.253.91.156, lip=150.253.10.10, TLS handshake And a few like this: Apr 10 09:17:48 cliff dovecot: imap-login: Disconnected: Shutting down: rip=66.93.16.227, lip=150.253.10.10, TLS handshake Any idea what that might indicate? -Ben

[Dovecot] What are the Key DC executables
by Stewart Dean 10 Apr '07

10 Apr '07

Back a year ago, I asked what the key DC executables where that I had to bring from my compile host to the production imap server to install or upgrade DC. I was told: dovecot, dovecot.conf, dovecot-auth, imap & imap-login I recently got DC up and running unencrypted and that worked fine. Then I tried to enable SSL and the logs said I was missing /usr/local/libexec/dovecot/ssl-build-param, which I located in the build tree under ./src/master. Is there anything else I need? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] /etc/passwd authentication anomalies
by Stewart Dean 10 Apr '07

10 Apr '07

I am using the base AIX Unix authentication with NIS. There is a base /etc/password file (though the passwords are in a funny, IBM-peculiar file, /etc/security/passed) of just 18 lines...since NIS is in use, the last line is the standard for-anything-you-don't-find-here-try NIS indicator: +::0:0::: When I start up DC, I get these error massages: Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User root has invalid UID 0 Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User kmem has invalid GID 0 Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User ipsec has invalid GID 0 Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User + has invalid UID 0 This is a niggle, but is there something I should do differently, or is DC just annoyed at what IBM has done with /etc/passwd? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] AFS maildirs & GSSAPI?
by Troy Benjegerdes 10 Apr '07

10 Apr '07

I saw some stuff about AFS maildirs awhile back, and dovecot seems happy being running via ssh from offlineimap with :INDEX=/tmp/dovecot-%u, but what I'd really like to know is has anyone got a functional dovecot installation with AFS and GSSAPI sasl support that gets the correct users's AFS tokens? Thanks -- -------------------------------------------------------------------------- Troy Benjegerdes 'da hozer' hozer(a)hozed.org Somone asked me why I work on this free (http://www.fsf.org/philosophy/) software stuff and not get a real job.

It's my life." -- Charles Shultz

[Dovecot] Request for additional logging
by Richard Stockton 10 Apr '07

10 Apr '07

Hi Timo, First, thanks very much for dovecot, you are doing a fine thing making it open source, and it is working very well here. It would be helpful to me if there were more logging options available. For example, I would like to see a record of each email deleted, with the filename (if maildir), and size in the log. I haven't been able to find much documentation on logging at all. Have I just not been looking in the right place? If so, I would appreciate any enlightenment offered. Thanks in advance, - Richard
