[Dovecot] vacation problem with sieve and sogo
by Pablo Luchetti 18 May '11

18 May '11

Hi, I have a problem with dovecot's sieve and SOGo ( http://www.sogo.nu/ ) I have installed last version of sogo ( 1.3.6) in one virtual machine with ubuntu, lucid. In another virtualmachine with ubuntu jaunty is running dovecot ( 1:1.1.11-0ubuntu4.1 ) When try to activate vacation function, after the "PUTSCRIPT "sogo" command, the manage-sieve answer: NO "Script name 'sogo' is reserved for internal use." And fails. But I found, telneting the mail server on port 2000 that if I change script name, all works fine: SETACTIVE "" OK "No scripts currently active." PUTSCRIPT "prueba" {536+} require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses ["pluchetti(a)example.org", "pablo.luchetti(a)example.org"] text: hoy es 27 de abril de 2011, y estoy probando el nuevo sogo. 10:40 . ; } redirect "pllis(a)educ.ar"; keep; OK "Putscript completed." SETACTIVE "prueba" OK "Setactive completed." logout OK "Logout completed." Connection closed by foreign host. So, the question is: Why does this happen? How can I fix it ? Any ideas? Here are dovecot's version and config: # dovecot --version 1.1.11 # dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-18-server i686 Ubuntu 9.04 log_path: /var/log/mail/dovecot-msa.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/local/WILD.jil_01+CHAIN.crt ssl_key_file: /etc/ssl/private/WILD.jil_01.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: JIL mail server ready. first_valid_uid: 106 last_valid_uid: 106 first_valid_gid: 112 last_valid_gid: 112 mail_privileged_group: mail mail_uid: vmail mail_gid: vmail mail_location: maildir:~ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login user: vmailauth passdb: driver: ldap args: /etc/dovecot/ldap-auth-userdb.conf userdb: driver: ldap args: /etc/dovecot/ldap-auth-userdb.conf socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: ~/sieve/s0g0.sieve Thanks!!

[Dovecot] IMAP message ID bad for very old message
by a.smith＠ukgrid.net 17 May '11

17 May '11

Hi, I just noticed that the ordering by message ID when accessing my email via IMAP is messed up. I'm looking in the INBOX that contains 11757 emails. For some reason a load of emails from 2009 and 2010 are being listed near the top, for example I have a message with ID 11441 from 2009 where it definitely shouldn't be, its all mixed in with emails from 2011 there. Info from LDAP is: * 11441 FETCH (FLAGS (\Answered \Seen) INTERNALDATE "27-Mar-2009 09:14:10 +0000" RFC822.SIZE 5772 ENVELOPE ("Fri, 27 Mar 2009 09:15:09 -0000" "MyC IP on CBL" (("Patrick XXXXXXXX- XXXXXXXX" NIL "patrick" "XXXXXXXX.co.uk")) (("Patrick XXXXXX- XXXXXXXX" NIL "patrick" "XXXXXXX.co.uk")) (("Patrick xxxxxx - xxxxxxx" NIL "patrick" "XXXXXXXX.co.uk")) (("Andy Smith" NIL "a.smith" "ukgrid.net")) (("Frank XXXXXXX" NIL "frank" "XXXXXXXXXXX.co.uk")(NIL NIL "Tim.XXXXXXXX" "XXXXXX.org")) NIL NIL "<6937D025FA924E73B8C839858C27AEBF@PatrickDesktop>")) I'm using maildir format, and the actual file date looks fine too: -rw-rw---- 1 vmail vmail 5627 Mar 27 2009 1238145250.H86871P67126.mx1.ukgrid.net:2,RS I am testing IMAP via telnet (originally noticed the problem viewing mail via HORDE/IMP). My system is FreeBSD 8.2, Dovecot 2.0.11. What might cause this behaviour? thanks Andy.

[Dovecot] Permission lookup failed with imap
by Alex 17 May '11

17 May '11

Hi all, I'm still trying to troubleshoot my problem with dovecot-2.0.11 and creating "mail/mail" directories for a reason unknown to me, so I enabled mail_debug. It's now printing this: May 15 21:39:33 mail dovecot: imap(gdadmin): Debug: Namespace : Using permissions from /home/gdadmin/mail: mode=0755 gid=-1 May 15 21:39:33 mail dovecot: imap(gdadmin): Debug: Namespace : Permission lookup failed from /home/gdadmin/mail/mail/INBOX. Trash That file (INBOX.Trash) does exist at that location and is readable. It prints that line three times for each of INBOX.Sent, INBOX.Trash, and INBOX.Drafts. Also notice that it is creating /home/user/mail/mail. My mail_location is set to "mbox:~/mail:INBOX=/var/spool/mail/%u", so I'm really confused. I really hope someone has some ideas! Thanks so much, Best, Alex
