[Dovecot] Issue with converting users from cyrus user.domain.com
by Preston Lord 13 Apr '09

13 Apr '09

I have been using cyrus for the past 6 years, but it is a pain to config. So ... I just installed dovecot 1.0.15 on a new debian 4r7 box. In cyrus we were using usernames as "user.domain.tld". In dovecot I realize I can: auth_username_translation = .@ But this converts user.domain.tld to user@domain@tld which of course fails. Is there a regex or something I can apply to pull this off? I also tried auth_username_format = %n.%d But I think this does the opposite of what I need. Any help is GREATLY appreciated. Thanks in advance P.

[Dovecot] deliver vs lda
by Timo Sirainen 12 Apr '09

12 Apr '09

deliver is the binary name. but it's configured inside protocol lda {} section. This is getting annoying, any thoughts on what would be a good unifying name? a) deliver binary, protocol deliver {} b) lda binary, protocol lda {} c) dovecot-lda binary, protocol lda {} d) mda binary, protocol mda {} e) dovecot-mda binary, protocol mda {} f) something else? In any case protocol lda {} would work for a while longer for backwards compatibility. c) and e) choices also makes me think if e.g. imap and imap-login should be called dovecot-imap and dovecot-imap-login instead. People have had trouble finding them since ps|grep dovecot doesn't find them..

[Dovecot] Dovecot crash
by Wolfgang.Friebel＠desy.de 12 Apr '09

12 Apr '09

tonight dovecot 1.2beta4 crashed for the first time with an assertion failed. See attached log file. Around that time nobody was logged in into dovecot and there were no other mail deliveries going on. The mail in question should have been delivered to three recipients, one got the mail, the two others not. There is unfortunately no core dump file. I have attached the dovecot -n output as well. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] allow_nets and deliver + userdb lookup
by Pavel Volkovitskiy 12 Apr '09

12 Apr '09

Hello! I'm trying to restrict imap logins to our internal network for several users, but this breaks dovecot delivery too Even if i set allow_nets to NULL or 0.0.0.0/0 deliver exits with "Error: Auth lookup returned failure" i'm running it as 'command = /usr/lib/dovecot/deliver -e -d "$local_part@$domain" -s' in exim.conf i guess delivery lookups should be independent of allow_nets i'm using dovecot 1.1.13 + managesieve patch -- Pavel

[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/
