[Dovecot] test49 "killed with signal 6" errors...
by jross＠wykids.org 20 Oct '04

20 Oct '04

I upgraded yesterday from 1.0test46 to 1.0test49 in an attempt to eliminate an error that a couple of my users were getting. Both users were using Thunderbird 0.6 over imaps, and were getting errors that said: "The current command didn't succeed. The mail server responded: Error in IMAP command UID: Invalid Body [..] Parameter: Missing '>'in'<14336-13057>'. When the user would click the Okay button on the e-mail client error message, the message would be delivered as normal. There wasn't any entry in the system logs about this that I could find. Googling didn't turn up anything concrete. I decided to upgrade to the latest test49 version. Now the same users are getting occasional e-mails that will not display, and I'm getting the follwing in the logs: 2004-10-20 09:48:51.854386500 mail.info: Oct 20 09:48:51 dovecot: imap-login: Login: jgarcia [69.146.158.154] 2004-10-20 09:49:13.195974500 mail.err: Oct 20 09:49:13 dovecot: IMAP(jgarcia): Trying to allocate 0 bytes 2004-10-20 09:49:13.197151500 mail.err: Oct 20 09:49:13 dovecot: child 14738 (imap) killed with signal 6 I upgraded one of the users to the latest Thunderbird with no change. But, if I have them go through our web interface (horde/imp) the same message displays just fine. The mail server is OpenBSD 3.6 -current. Dovecot is built with the following configuration: ./configure --sysconfdir=/etc \ --with-ssl=openssl \ --with-pam=NO \ --with-ldap=no \ --with-vpopmail=no \ --with-rawlog I added the --with-rawlog switch yesterday and created a dovecot.rawlog folder in the Maildirs but nothing seems to be logged. Any other information I can provide please let me know. Thanks, Jeff Ross -- http://wykids.org/

[Dovecot] dovecot failing to chdir in home
by Stefano Maffulli 20 Oct '04

20 Oct '04

Hi all, I have been fiddling with dovecot and things seem to be stuck on this problem: Oct 20 11:21:35 mail dovecot: chdir(studiosala.net/federico/) failed with uid 1001: Permission denied Oct 20 11:21:35 mail dovecot: child 22150 (pop3) returned error 89 This is the telnet session that generates it: mail:~# telnet localhost pop3 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. +OK dovecot ready. user federico(a)studiosala.net +OK pass XXXXXX +OK Logged in. Connection closed by foreign host. I am stuck: the UID/GID that postfix uses for dropping the mail in /varm/mail/domains/ is 1001/1001. The query string to mysql (the backend where I have stored the users) is (from mysql log, so it is executed): 682 Query SELECT 1001 AS uid, 1001 AS gid, '/var/mail/domains/' AS mail, maildir AS home FROM mailbox WHERE username = 'ale(a)studiosala.net' mail:/etc# ls -lad /var/mail drwxrwsr-t 3 root mail 4096 2004-10-19 23:49 /var/mail mail:/etc# ls -lad /var/mail/domains/ drwxr-sr-t 4 vmail vmail 4096 2004-10-20 07:03 /var/mail/domains/ I am not sure of how to proceed from here, any hint appreciated. thanks stef

[Dovecot] default_mail_env problems
by Neil Marjoram 20 Oct '04

20 Oct '04

sorry if this mail is a duplicate - I am testing the new mail system! I am having problems setting the default mail environment.# I am using Fedora Core 2 with version dovecot-0.99.10.5-0.FC2 My users all have an NFS mounted home directory, and all mail is delivered to ~Mail/.mailbox it is all mbox format. I would like to put the indexes on the local system in /var/indexes/{username}. So I set these parameters for default_mail_env : mbox:~/Mail/:INBOX=~/Mail/.mailbox Which produced the error : imap(test): stat() failed with mbox file ~/Mail/.mailbox: No such file or directory I set the mail environment back to default, linked inbox to .mailbox in the ~/Mail directory and all worked fine. Is there a better way to do this ? I would like to put the indexes on the local system in /var/indexes/{username}, so I decided to set: default_mail_env = INDEX=/var/indexes/%d/%n and got this error: imap(test): Failed to create storage with data: INDEX=/var/indexes//test dovecot: child 9142 (imap) returned error 89 I also tried : default_mail_env = INDEX=/var/indexes/%u And got the same error. I guessed at permissions, so I tried changing the ownership to dovecot and then test and then root and then 777, but I still get this error. Can anyone tell me where I am going wrong? Many thanks, Neil. -- Neil Marjoram. Systems Manager University College London Adastral Park Campus Martlesham Heath Ipswich Suffolk IP5 3RL 01473 663711

[Dovecot] Occasional error msgs from 1.0-test49
by Gregory Bond 20 Oct '04

20 Oct '04

I'm running 1.0-test49 on Solaris 2.8. MUA is Thunderbird (or mutt) running on FreeBSD. I'm using Maildir boxes. Occasionally, when browsing new mail in INBOX, I get an error back from the imapd, displayed in Thunderbird as the following popup msg: The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' in '<36864,-34800>'. >From this point, nothing much works reliably until I quit the MUA and start again. Sometimes, if I keep working, the email that was being fetched is shown but is corrupted and the msg body contains another copy of the whole email (header & body), sometimes 2 extra copies. Nothing is in the maillog. This _didn't_ happen with 0.99.

[Dovecot] 1.0-test49 FD leak
by Gregory Bond 19 Oct '04

19 Oct '04

I'm running 1.0-test49 on Solaris 2.8. The good news is that this version fixes my problem with corrupted index files (so far). The bad news is it seems to be leaking FDs to do with inbox: imap 10198 gnb 156r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 157r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 158r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 159r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 160r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 161r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 162r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 163r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 164r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 165r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur (seems to be a new pair of FDs leaked each time my MUA checks for new mail).

Very good, this compile problem though on test49-latest from nightly: ar cru libpassword.a mycrypt.o password-scheme.o password-scheme-md5crypt.o password-scheme-cram-md5.o password-scheme-ntlm.o password-scheme-rpa.o ranlib libpassword.a make: don't know how to make auth-master-interface.h. Stop Also, tried getting the cvs tree with: cvs -d :pserver:anonymous@dovecot.org:/home/cvs co dovecot It doesn't populate the directory with all the files; does not include the build files such as Makefile.in, configure etc Any way to get cvs to do that ? -kim _______________________________ Do you Yahoo!?

[Dovecot] Index corruption
by Gregory Bond 18 Oct '04

18 Oct '04

I'm getting pretty constant index corruption on (admittedly large) Maildir folders. I'm running Thunderbird 0.7.3 and Mutt as my IMAP clients (on FreeBSD). Server is Dovecot 0.99.10.9 configured thusly: ./configure --disable-ipv6 CC=gcc-3.3 CXX=g++-3.3 --prefix=/opt/dovecot --without-pop3d on a Solaris 2.8 box. Maildirs are NFS-mounted, but the index files are on local UFS filesystem: default_mail_env = maildir:~/Maildir:INDEX=/export/01/imapd/%u MTA is Postfix, LDA is procmail delivering to several Maildir folders. There will be 2 (or more) dovecot instances running for this user (me) - several from Thunderbird and one from the BIFF client (icewm). Turning off the BIFF client doesn't seem to help. Symptoms: when using Thunderbird, and deleting a msg or moving it to another folder, Thunderbird will sometimes not display the next unread message, but just sit there. Changing folders works, but changing back to the previous folder (or quitting/restarting Thunderbird) only shows the first N messages (N is about 500, in a Maildir of about 6000, and it is the SAME email that is "last" every time.) This happens with multiple folders, but (usually) only folders that are delivered to by procmail (this may be related to the problem or a coincidence in that only those folders have unread email!) Accessing the mailboxes using MUTT via IMAP shows the same truncated message list. (I'm the only user using dovecot as I want Maildir, the other users have uw-imap, so dovecot is listening on port 4343) Closing all imap clients, then removing the .index.* files from the appropriate /export/01/imapd/ directory, then restarting the imap client causes the missing messages to reappear (after a suitable wait for the index files to be recreated). It really looks like locking or truncation issues in the index files.... Any clues? Debugging hints? This is happening several times per day so I can get lots o' debug data! Greg.

[Dovecot] test49 Authenticate PLAIN disabled stops pop3s
by Kim Culhan 18 Oct '04

18 Oct '04

Unlike test47, test49 refuses to authenticate pop3s if disable_plaintext_auth = yes Checked the crypto with: snort -vde tcp port 995 The connection is being made with ssl so it looks like the plaintext auth preventer is broken. -kim __________________________________________________ Do You Yahoo!?

[Dovecot] UIDL bug
by dovecot＠spam.turbolink.net 16 Oct '04

16 Oct '04

I noticed a problem with handling UIDL msgnumber in test46. If you do "UIDL 1" on a POP3 connection it returns the UID of the message followed by a dot and an error message. I made 2 changes: I added the following line to line 527 of src/pop3/commands.c ctx->message = message; I changed line 559 from: if (list_uids_iter(client, ctx)) to: if (!list_uids_iter(client, ctx)) Next time I'll submit an actual diff, I've made lots of other changes and comments in my source though so it's harder. - Mike
