[Dovecot] outlook problem if TLS mailsettings are off
by Georg Käfer 10 Apr '09

10 Apr '09

Dear List, I dont know if its a dovecot config problem or whatever else issue. Behaviour: If I set /etc/dovecot/dovecot.conf: Following is valid with IMAP mailboxes only: disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again) with POP3 mailbox both variants are working smoothly. Other ssl/tls settings: ssl_disable = no login_process_per_connection = yes using or not using following makes no difference... imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh I'm sad - but I can't force SSL/TLS for my users - so I can't "solve" this by using "disable_plaintext_auth = yes" Is there any way out of the dark? my data: gentoo linux dovecot 1.1.7 postfix 2.5.5 postfixadmin-2.2.1.1 mysql 5.0.70-r1 php 5.2.8-pl12 dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-gentoo-r3 i686 Gentoo Base System release 1.12.11.1 ext3 protocols: pop3 pop3s imap imaps ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 30 first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 12 last_valid_gid: 12 mail_privileged_group: mail mail_uid: mail mail_gid: mail mail_location: maildir:/var/mail/%d/%n/Maildir/:INDEX=/var/mail/%d/%n/indexes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail regards, Georg Kaefer

[Dovecot] Postfix + Dovecot + Sieve + SpamAssassin
by Sascha Scandella 10 Apr '09

10 Apr '09

Hello Until now I used Postfix in combination with Procmail and Dovecot. I am convinced that the Dovecot Sieve plugin is a much more elegant solution. So I changed to Postfix + Dovcecot Deliver + Dovecot + Sieve. If I understood correctly I cannot call other applications within a Sieve script. Until now I used Procmail to filter Spam Messages with SpamAssassin. Is there a possibility to filter spam messages before/after Dovecot deliver. I want to use the users .spammassassin user_prefs located in their home folder. I suppose if I use a content filter in Postfix this is to early, since the user is not known at that moment. Or am I wrong? Any help is highly appreciated. Best regards, Sascha

[Dovecot] About "Status" to the header
by ogu_yo＠yahoo.co.jp 10 Apr '09

10 Apr '09

hi list, I'd like to know about "Status" to the header on dovecot. I can see the "Status" to the header in /var/spool/mail/user if I check mail by using mutt, but I cannot see "Status" to the header if I check mail by using evolution, thunderbird etc. - /var/spool/mail/user -------------------------------------- To: test(a)test.example.com Subject: test Status: RO Content-Length: 0 Lines: 0 -------------------------------------- Then, there is a question. Which one is the reason of that cannot see "Status" to the header with evolution and thunderbird? - there isn't "Status" to the header - there is "Status" to the header, but just cannot see Thanks in advance. Regards, Yoko -------------------------------------- Power up the Internet with Yahoo! Toolbar. http://pr.mail.yahoo.co.jp/toolbar/

[Dovecot] dbox problem
by Xueron Nee 09 Apr '09

09 Apr '09

Hi, I have just tested the dbox format mailbox, it works fine. But when I create dir through imap with `create` command, it only creates the dir onder ~/dbox/mailboxes, such as ~/dbox/mailboxes/newfolder. There was no `dbox-Mails` dir created. So the newfolder was 'noselect'. But the new folders created by `autocreate` plugin was correct. -- Xueron Nee http://www.xueron.com

[Dovecot] Indexing of mails to speed up the IMAP SEARCH command
by Tassilo Horn 09 Apr '09

09 Apr '09

Hi all, I use a local dovecot server which is synchronized with my two imap accounts using OfflineIMAP. This works very nice and is highly usable. But one thing I'd like to improve is the slow IMAP search. When I search for a string in the subjects of all messages in a mailbox using some mail client, dovecot seems to grep all the messages in there. Is there a way to let dovecot index more informations which are then used to speed up the SEARCH command? Bye, Tassilo

[Dovecot] Moving IMAP folders to NFS volume.
by Frank Bonnet 09 Apr '09

09 Apr '09

Hello Due to lack of disk space on local disks I need to move all our imap folders to a NFS volume ( NetAPP filer ) I have a question about Dovecot indexes , is it better to remove all of them before copying folders to the NFS volume and let Dovecot rebuild all indexes when users restart to access to their imap folders ? Thanks a lot.
