[Dovecot] Dovecot cannot unlink non-empty directory
by Włodek Waligórski 16 Sep '08

16 Sep '08

Hi, Currently I use dovecot 1.1.3 on Debian Testing. CPU arch is x86. Mail is stored on ext3 fs. I'm having a following problem with deleting folders (there is no problem with creation of folders): Error: IMAP(test(a)laptop.aonet.pl): unlink_directory(/home/vpopmail/domains/laptop.aonet.pl/test/.//Maildir/..DOVECOT-TRASHED) failed: Permission denied HOW TO REPRODUCE 1. Create a fresh new account 2. Login to a new account and create folder say 'TestFolder' 3. When I try to delete TestFolder - it is deleted and ..DOVECOT-TRASHED appears in user's Maildir AND Error: IMAP(test(a)laptop.aonet.pl): unlink_directory(/home/vpopmail/domains/laptop.aonet.pl/test/.//Maildir/..DOVECOT-TRASHED) failed: Permission denied message appears - it is triggered from line 815 of dovecot-1.1.3/src/lib-storage/index/maildir/maildir-storage.c 4. Create 'TestFolder2' 5. Trying to delete 'TestFolder2' gives the same error: Error: IMAP(test(a)laptop.aonet.pl): unlink_directory(/home/vpopmail/domains/laptop.aonet.pl/test/.//Maildir/..DOVECOT-TRASHED) failed: Permission denied this one however, is triggered from line 806 of dovecot-1.1.3/src/lib-storage/index/maildir/maildir-storage.c 6. The folder 'TestFolder2' is not deleted and from this point no other newly created folders can be deleted too. --------------------------------------------------------- I. Yes, the file permissions are fine - all are writeable to (mail_uid = vpopmail) II. The problem is - dovecot cannot unlink non-empty directory, I artificially deleted contents of ..DOVECOT-TRASHED and dovecot allowed folder deletion from client. After that situation was like in point 4. -My-config------------------------------------------------------ # 1.1.3: /usr/local/etc/dovecot.conf base_dir: /usr/local/var/run/dovecot/ log_path: /dev/stderr info_log_path: /dev/stderr log_timestamp: listen: 127.0.0.1:143 ssl_listen: 0:993 ssl_cert_file: /var/qmail/control/servercert.pem ssl_key_file: /var/qmail/control/servercert.pem ssl_cipher_list: ALL:!LOW verbose_ssl: yes login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 mail_uid: vpopmail mail_gid: vchkpw mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle auth default: user: vpopmail verbose: yes debug: yes passdb: driver: vpopmail args: quota_template=quota_rule=*:backend=%q userdb: driver: vpopmail plugin: quota: maildir quota_rule: ?:storage=110485760 quota_rule2: Trash:ignore quota_rule3: SPAM:ignore quota_warning: storage=90%% /usr/local/bin/imap-quota-warning 90 ---------------------------------------------------------------------- is this my mistake in configuration or is dovecot doing something wrong? tnx for help, -Włodek

[Dovecot] Blackberry suggestions?
by Ed W 14 Sep '08

14 Sep '08

Hi, I'm not a Blackberry user, but we have some customers currently using an Exchange server with some kind of blackberry and interested in moving their service over to our dovecot 1.1 server Does anyone have any notes or recommendations on getting a (UK) Blackberry to talk effectively to a normal Dovecot server, and are there any things to consider in order to get whatever features they are normally using on their Exchange link working on the Dovecot server? (It's just a small couple of person office on an Exchange server) Thanks for any thoughts/tips Ed W

[Dovecot] cram-md5 and users maintaining their own passwords?
by Steinar Bang 13 Sep '08

13 Sep '08

Is there any other mechanism than using passwd files with md5-hashed passwords created by dovecotpw that will support cram-md5 authentication? Has anyone created setups where the passwd databases reside in the individual users home directories? Is it possible to persuade dovecotpw to update the passwd databases automatically. Having to use a text editor to paste in the passwords sets a high user treshold on using the cram-md5 authentication mechanism. Thanx! - Steinar

[Dovecot] Questions about using sieve
by Robin Atwood 13 Sep '08

13 Sep '08

I am trying to filter my imap mail sent to my phone by using sieve. Currently everything is set up and works well using mbox and sendmail as the lda. I have re-installed dovecot with sieve included and updated dovecot.conf, which gives # dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u auth default: passdb: driver: pam args: * userdb: driver: passwd and I have added "mail_plugins = cmusieve" to protocol lda{}. I then created a ".dovecot.sieve" script but am not sure where to place it. I tried ~/ and ~/.imap but it never seems to get compiled. Dovecot is running as a root service so it should have access. Setting mail_debug=yes produces no clues, so what should I be looking at? TIA -Robin -- ---------------------------------------------------------------------- Robin Atwood.

[Dovecot] API Examples?
by tcowin 13 Sep '08

13 Sep '08

I need to write a little client to just get the 5 most recent email headers (and \Seen status) from the INBOX of a given user. Are there any API examples anywhere that would speed this process along, or any spots in the source that would give me a jump start? or would it be better to act as an IMAP client? Many Thanks In Advance, Tom -- View this message in context: http://www.nabble.com/API-Examples--tp19444931p19444931.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 1.1.3 Kerberos5 GSSAPI bug (with patch)
by Matthew Wesley 12 Sep '08

12 Sep '08

The functionality added in changeset 818a638fa9a3 has a bug for x86_64 on line 103. The src/auth/mech-gssapi.c file must now include stdlib.h to have the declaration for getenv(). Otherwise, the compiler uses the implicit return type (int), which truncates the 8-byte pointer getenv() returns to a 4-byte value. This causes a segfault on subsequent reads. Here is debugger output illustrating the problem: (gdb) list 106 101 const char *path; 102 103 path = getenv("KRB5_KTNAME"); 104 if (path != NULL) { 105 #ifdef HAVE_GSSKRB5_REGISTER_ACCEPTOR_IDENTITY 106 gsskrb5_register_acceptor_identity(path); 107 #elif defined (HAVE_KRB5_GSS_REGISTER_ACCEPTOR_IDENTITY) 108 krb5_gss_register_acceptor_identity(path); 109 #endif 110 } (gdb) p/x getenv("KRB5_KTNAME") $32 = 0xb0d7aef7 (gdb) x/s 0xb0d7aef7 0xb0d7aef7: <Address 0xb0d7aef7 out of bounds> (gdb) x/s 0x7fffb0d7aef7 0x7fffb0d7aef7: "/etc/dovecot/dovecot.keytab" A Mercurial bundle with a fix is attached, and here is the trivial patch to put in the needed #include: diff -r 43e55b9af85b src/auth/mech-gssapi.c --- a/src/auth/mech-gssapi.c Mon Sep 01 15:02:49 2008 +0300 +++ b/src/auth/mech-gssapi.c Wed Sep 03 11:37:33 2008 -0400 @@ -22,6 +22,8 @@ #include "safe-memset.h" #ifdef HAVE_GSSAPI + +#include <stdlib.h> #ifndef HAVE___GSS_USEROK # define USE_KRB5_USEROK -- UNIX was not designed to stop you from doing stupid things, because that would also stop you from doing clever things. -- Doug Gwyn
