[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

Ive been getting a LOT of these errors since 1.1.2: So far ive seen this with 1800 customers, and we're getting active complaints about errors in imap clients. When I check the users log I always see this error.. This always happens with COPY commands in Squirrelmail.

[Dovecot] Public (Shared Folders) ACL Questions
by Mailing List 11 Sep '08

11 Sep '08

I'm trying to set up a public namespace so that a set of IMAP folders are available to all staff - similar to MS Exchange Public Folders. I've managed to set up the namespace correctly but I'm having trouble with the ACLs. The global ACL file is the only method I can get to work. All I want to do is to allow 1 user admin privileges to create & delete anything but all other users should only be able to create not delete. Reading through the mailing list I thought a /etc/dovecot-acls/.DEFAULT file would be suitable but what should be put in here to achieve what I want? Are you able to use wildcards somehow within this file, i.e.: ---------------------------------------- owner lrwstiekxa user=admin(a)domain.com lrwstiekxa user=*(a)domain.com lrw ---------------------------------------- Does this .DEFAULT file only apply to the public (shared) namespace or will it effect private mailboxes also? If I was to create a specific global acl file for a specific folder which would take precedence, the .DEFAULT acls or the specific folder acls? Also an "INBOX" is shown within the public folders namespace but no folder exists in the public folders maildir hierarchy - any ideas how I can stop this? Any help would be greatly appreciated. Gavin

[Dovecot] Stumped on adding X-Header...
by Brian Hayden 11 Sep '08

11 Sep '08

Recently I posted about wanting to add an x-header recording a timestamp for changing the \Deleted flag, for purposes of doing expiry on mbox mailboxes. Timo replied: > Be sure to add it to mbox_hide_headers[] and mbox_save_drop_headers[] > arrays in mbox-storage.c and hope that it doesn't exist in any of your > existing mails. :) Other than that there shouldn't be problems. I looked at the two places where X-Status was being written--mbox-save.c and mbox-sync-update.c--and tried adding this header. It didn't work. To test my sanity, I changed the string 'X-Status' in each of these to something else. The mbox file still ended up with 'X-Status' written in it, and I can't for the life of me find any other code that might write that string. Timo? Anyone? -- Brian Hayden UMN OIT Internet Services
