[dovecot] Dovecot on FreeBSD
by Karo Salminen 06 Feb '03

06 Feb '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I built Dovecot (0.99.5) from Ports on FreeBSD 5.0. The mail client (Kmail) cannot login and it complains that authentication process died. The only thing in the logs is: Feb 2 18:13:01 karo imap-login: Disconnected [client-ip] I tried also passwd authentication method, but its symptoms are the very same. My configure can be found at http://people.jyu.fi/~kaeesalm/dovecot.conf I also tried CVS version in hope of fix and more comprehensive debug messages. The compilation failes when it tries to look for passwd.h even though I set - --disable-passwd and --without-passwd to configure parameters. Could someone fix that. - -- Karo Salminen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQE+PUX0vt6lNXuj7xcRAp70AJ0R+zhmgF+WBaXaX2V2j+07eVyJRACgh6Ze Pmep2Uy2OnVe/EVuo9O3b80= =eqOO -----END PGP SIGNATURE-----

[dovecot] 0.99.8-test1 released
by Timo Sirainen 04 Feb '03

04 Feb '03

I think all of the reported bugs are again fixed in CVS, so I made a tarball of it. I'd like to hear if there's any problems with it. Here's the most important changes: v0.99.8 2003-02-xx Timo Sirainen <tss(a)iki.fi> * NOTE: Configuration file has changed a bit: auth_userinfo was replaced by userdb and passdb. *_port were merged into *_listen. Disabling listening in imaps port is now done by changing protocols setting. + Fully featured POP3 server included. Disabled by default. + Support for LITERAL+, MULTIAPPEND and UNSELECT extensions. + Internal API cleanups made Dovecot faster and take less memory + auth_verbose logs now all authentication failures + Support for Solaris 9 sendfilev() (not really tested) - COPY now behaves as RFC2060 says: "If the COPY command is unsuccessful for any reason, server implementations MUST restore the destination mailbox to its state before the COPY attempt." - maildir_copy_with_hardlinks = yes was broken. - mboxes in subfolders weren't selectable. - STORE didn't accept multiple flags without () around them - PLAIN SASL-authentication was a bit broken. - IMAP dates were parsed a few hours wrong - If auth/login process died unexpectedly at startup, the exit status or killing signal wasn't logged. - mbox parsing might have crashed sometimes - Next command after STARTTLS was ignored which left the connection stuck sometimes - STATUS command removed \Recent flags from messages - Several bugfixes to SEARCH command, especially related to multiple search conditions

[dovecot] Recent messages
by Jaime Medrano 03 Feb '03

03 Feb '03

Dovecot seems to manage \Recent messages in a weird way. When a STATUS command is performed in a mailbox, then the \Recent flag of its messages disappear and latter STATUS commands report that there are no recent messagges. I don't know exactly the behavior of the RFC. But other imap servers (UW-imapd, Netscape Messenger...) report the same number of recent messages when two STATUS commands are performed together. -- Jaime.

[dovecot] Unable to Log in on FreeBSD server?
by Mark 21 Jan '03

21 Jan '03

Hello! I recently compiled dovecot 0.99.7 on a FreeBSD 4.3 server, and have been having problems with logging in and password authentication. a. I can't seem to get it to compile MD5 support -- it only seems to support plain, plain-file, and pam. b. Whenever I try to log in, I always get something along the following lines in /var/log/messages .... Jan 16 17:52:15 akira imap-login: close(master) failed: Bad file descriptor Jan 16 17:55:33 akira imap-auth: Userinfo pam doesn't support DIGEST-MD5 method Jan 16 18:08:28 akira imap-master: Login process died too early - shutting down (I also included one about MD5 in there too! :-)) Basically, the imap-login process is dying every time I try to do a login from a remote machine (I've tried Evolution and Outlook Express ....) I've tried telling it to use port 143 and port 993 (where it correctly generates a warning about a certificate that it can't verify, since i created that certificate with mkcert.sh ) Is there something I haven't configured correctly? The only things I've changed in dovecot.conf are: Any suggestions? Thanks, Marc.

[dovecot] mbox & Maildir
by james broermann 18 Jan '03

18 Jan '03

Hi, Is it possible for a client to read both mbox and Maildir formats from one server running dovecot? Without changing default_mail_env in dovecot.conf, Maildir folders are working ... they're located in ~/Maildir. No /var/mail/username exists. I have mbox format folders in ~/mail and have been trying to get pine to find them by adding pine folder collections. I always end up back in ~/Maildir, though. Thanks, Jim

Just a note, the hash table code in it was still buggy. Especially with maildir it could leave the processes to infinite loop. Have to think a bit more how to fix this properly..

[dovecot] security audit of the code

Timo, I know that you're taking an effort to make sure that dovecot is written securely, but I was wondering if you've asked any third party to audit the code yet. I don't have the skills necessary to do this but I bet there is someone out there who does and might be willing to do so. -sv

If client had already successfully done the BODY fetching a couple of times, the bug couldn't happen anymore since Dovecot then began caching the BODY data.

[dovecot] 0.99.6rc3
by Timo Sirainen 13 Jan '03

13 Jan '03

Well, "release candidate" wasn't really right name for last two versions. Maybe not for this one either, it has a few changes that could potentially break things badly (new hash table code especially). Anyway, seems to work with me. If I don't see any problems with it for a few days it'll be the final. The really great news is that we support threading. A lot of people have not used Dovecot simply because it couldn't be used for webmails. Hmm. What's the next most important feature? .. Better mbox support? Shared folders? Quota? LDAP/MySQL/etc. authentication? Here's the change summary: v0.99.6 2003-01-xx Timo Sirainen <tss(a)iki.fi> + THREAD=REFERENCES extension support.

Hi, I'm impressed so far, I tested this before trying to run it on a mail server and it worked find. However on the mail server with the same config I get the following message when I try and authenticate, and it drops the connection. Failed to create storage with data: mbox:/var/mail/martin The test box is running debian unstable and the mail server is running debian stable so I had to recompile and install. I'm failry sure that I got all the permissions right, I feel like I'm missing something obvious, can anyone advise? The file and permissions on the mailbox look right: -rw-rw---- 1 martin mail 14743740 Jan 10 06:29 /var/mail/martin -- Thanks, M

Well, one was just my misunderstanding of the specs, but another still exists: These should be grouped together, but aren't: Subject: =?iso-8859-1?Q?foo?= Subject: =?iso-8859-1?Q?RE=3A_foo?= UW doesn't seem to handle MIME encoded-words properly. I mentioned this already to Mark Crispin who apparently has a lot to do with UW's code. I didn't look too closely at Courier's output, except it was somewhat different from Dovecot's.

[dovecot] Thread extension
by Timo Sirainen 10 Jan '03

10 Jan '03

Just figured I'd mention that CVS supports now THREAD extension. I also did a bit of benchmarking using a folder with 4685 mails (evolution mailing list): dovecot+mbox: - 0.59s user 0.01s system 98% cpu 0.608 total - malloc() memory usage 45072 -> 825685 dovecot+maildir: - 0.60s user 0.17s system 98% cpu 0.780 total - malloc() memory usage: 45003 -> 825480 Meaning it takes almost 800kbytes of memory and it's quite fast :) Comparing to other servers then: uw-imap: - 1.11s user 0.27s system 100% cpu 1.376 total - malloc() memory usage: 529408 -> ~4348k courier: - 7.27s user 0.28s system 99% cpu 7.567 total - malloc() memory usage: 181689 -> ~850k cyrus: - 1.403 total (through TCP connection, I couldn't figure out how to start it separately) Whoa, we beat everyone :) Courier uses a bit less memory though, but that's most likely because we allocate it in larger chunks which is faster. I ran the tests several times and picked the best values, although the changes were minimal once they got the messages into OS's cache. Also it looks like I've found a couple of bugs in uw-imap and courier's implementation..

[dovecot] Logging suggestions?
by Timo Sirainen 09 Jan '03

09 Jan '03

Any suggestions how user login/logouts should look like in log files? I was thinking: (connected to imaps port) Login: username [IP 1.2.3.4, imaps, compressed] Logout: username [IP 1.2.3.4, imaps, compressed] [1000/100000 bytes (50%), 00:00:12] Bytes being upload/download and the 50% meaning compression ratio for downloaded bytes, probably not worth it for upload. Or if uncompressed, it'd show the extra space used by SSL/TLS protocol: (using STARTTLS) Login: username [IP 1.2.3.4, TLS] Logout: username [IP 1.2.3.4, TLS] [2020/202000 bytes (101%), 00:00:12] (no SSL) Login: username [IP 1.2.3.4] Logout: username [IP 1.2.3.4] [2000/200000 bytes, 00:00:12] I think the only configuration needed would be if to log login, logout or both.

[dovecot] Bug#175509: dovecot: init.d script should add some syslog statements on startup/shutdown (fwd)
by Jaldhar H. Vyas 08 Jan '03

08 Jan '03

[Amelia and Timo. As you are both on the dovecot list, I'm replying there to avoid cluttering up your inboxes.] This bug was reported to Debian but I feel it should be fixed upstream. Adding logging in th init script itself would require adding additional dependencies to the package and not be as convenient. ---------- Forwarded message ---------- From: Amelia A Lewis <amyzing(a)talsever.com> It would be nice if the init.d script could add some statements in the system log on startup and shutdown. For postfix, postfix-script (called from the init script) uses: starting the Postfix mail system stopping the Postfix mail system These are useful; one can start the daemon and check that it's initialized (netstat works as well, I suppose, but this is still useful docco). -- Jaldhar H.

Again rc, just in case I broke something. Or maybe I should just start creating nightly CVS snapshots. Anyway, fixes the few bugs people have reported lately: - Mails with nested MIME parts might have caused incorrect BODY and BODYSTRUCTURE fetches and sometimes might have crashed dovecot (assert at imap-bodystructure.c). If client had already successfully done the BODY fetching a couple of times, the bug couldn't happen anymore since Dovecot then began caching the BODY data. So, this mostly happened with new users. - If authentication was aborted by client ("*" reply to AUTHENTICATE), the login process crashed later. - Digest-MD5: We used "qop-options" instead of "qop", which was incompatible with at least Cyrus SASL. - We didn't work with some 64bit systems - Realms in passwd-file were buggy * Some coding style changes (less typedefs)

[dovecot] Assert in imap-bodystructure.c

First let me thank you for my initial newby question about poping from a pop3 server and delivering into my Dovecot maildir folders. Now I'm getting an assertion in imap-bodystructure.c and one of my imap folders is now inaccessable. I think the two are related. Whenever I select the folder from my email client (kmail) I get two log entries in the dovecot log of the format: "imap-master: <date>Error: child <pid> (imap) killed with signal 6" Also in the log are several lines with an assertion failure. I've included a portion of the log below. I am running dovecot 0.99.5.

[dovecot] Weird problem on Alpha
by Amelia A.Lewis 06 Jan '03

06 Jan '03

Heyas ... Hope you aren't tired of me already .... I have a very strange problem, I think. Having become happy-happy with dovecot, I decided to install it on another machine that runs on an internal network and provides mailboxes for system monitoring. The setup is, or should be, quite straightforward. TLS is disabled, plaintext is not (I'll change this later, probably; this way is in theory easier to debug). Maildir; the MAIL environment variable is correctly set. Authentication via pam, for real users on the system, auth_user root. Pretty much as-distributed, except for disabling TLS. On attempted login, the client hangs. The following two messages appear in syslog: Jan 5 21:42:43 talifane imap-master: login: received another "not listening" notification Jan 5 21:43:43 talifane imap-login: Disconnected: Inactivity [127.0.0.1] Watching on lo via tcpdump, interesting things happen. If I login with the wrong password, the disconnect is quick (the message in syslog is different, just "Disconnected [127.0.0.1]" from imap-login). The server responds to the a0001 LOGIN command with a0001 NO Authentication failed. That's as expected. If I give the correct password, though, the server never responds. Note that the 'not listening' message appears sixty seconds before the disconnection for inactivity message. In tcpdump, it's clear that the client never gets anything that would give it reason to try another command. So ... have I managed to pull a total bimbo and misconfigure? Or is this a problem with the Alpha platform? I wanted to check before reporting a bug, but this is kinda strange, since it's about the simplest configuration that I can think of. Suggestions (for testing, or for fixing) would be welcome. Is there a way to start the daemon in a particularly verbose mode? In case it's useful, here's what the debian reportbug system generates for dependencies and stuff (0.99.5-1): -- System Information: Debian Release: testing/unstable Architecture: alpha Kernel: Linux talifane 2.4.19 #1 Sat Aug 3 10:33:38 EDT 2002 alpha Locale: LANG=en_US, LC_CTYPE=en_US Versions of packages dovecot depends on: ii libc6.1 2.3.1-9 GNU C Library: Shared libraries an ii libgcrypt1 1.1.10-2 LGPL Crypto library - runtime libr ii libgnutls5 0.6.0-2 GNU TLS library - runtime library ii libpam0g 0.76-9 Pluggable Authentication Modules l ii libtasn1-0 0.1.2-1 Manage ASN.1 structures (runtime) ii openssl 0.9.6g-10 Secure Socket Layer (SSL) binary a ii zlib1g 1:1.1.4-8 compression library - runtime It's specifically a PC164LX/533, 512MB RAM.
