[Dovecot] v1.1.beta5 released
by Timo Sirainen 02 Nov '07

02 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz.sig APPEND should be working now. Also lots of fixes to handling namespace prefixes and namespaces where virtual separator differs from real separator. zlib plugin now supports opening compressed maildir files. This is done for files that have Z flag. SORT still assert-crashes sometimes. Would be great if someone could show me how to reproduce it. SEARCH TEXT or Squat indexes apparently still have some problems, but I couldn't reproduce them (http://dovecot.org/list/dovecot/2007-October/026254.html).

http://dovecot.org/releases/1.0/dovecot-1.0.6.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.6.tar.gz.sig * IDLE: Interval between mailbox change notifies is now 1 second, because some clients keep a long-running IDLE connection and use other connections to actually read the mails. * SORT: If Date: header is missing or broken, fallback to using INTERNALDATE (as the SORT draft nowadays specifies). + deliver: If message begins with a "From " line, ignore it. + zlib plugin: If maildir file has a "Z" flag, open it with zlib. - CREATE: Don't assert-crash if trying to create namespace prefix. - SEARCH: Fixes to handling NOT operator with sequence ranges. - LDAP reconnection fixes - Maildir: Don't break when renaming mailboxes with '*' or '%' characters and children. - mbox: Fixed "file size unexpectedly shrinked" error in some conditions. - quota+mbox: Don't fail if trying to delete a directory. - Fixes to running from inetd

[Dovecot] "Can't sync delivery mail"
by Rich Winkel 02 Nov '07

Dovecot 1.0.3 Deliver is saying this on two specific emails. Other emails to these 2 users are going through fine. Looking at the mail headers the only thing questionable I see is: From: "AMS Publication Division"@ams.org Is this the problem? # 1.0.3: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_disable: yes shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no first_valid_uid: 100 mail_extra_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot_indexes/%u lock_method: flock mbox_read_locks: flock mbox_write_locks: flock mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 432 user: dovecot group: dovecot

[Dovecot] Bug within Authentication Caching
by Matthias Waffenschmidt 02 Nov '07

02 Nov '07

Hello, there seems to be a bug in the authentication caching code when using it in combination with username_translation (using the current version 1.0.7 on FreeBSD 6). I've set username_translation to +@:@ to allow usernames of the form test+dom.ain or test:dom.ain (historical reasons force us....). If someone has a successful login using the username test(a)dom.ain, the subsequent authentication information is read from the cache, no matter which of the 3 possible usernames the client uses the next time. But if someone has a successful login using the username test+dom.ain, the following data has or has not been found in the cache: test+dom.ain: miss test(a)dom.ain: miss test:dom.ain: hit If the first username is test:dom.ain the behaviour is the following: test:dom.ain: miss test(a)dom.ain: miss test+dom.ain: hit I've added the information if the username changes for better debugging possibilities. In practice the username is of course always the same. The complete authentication part of the tested config: auth default: cache_size: 10000 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@:+ username_translation: +@:@ verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /var/pop/%d/Accounts.passwd userdb: driver: static args: uid=70 gid=70 home=/var/emtpy It looks as if Dovecot does some wrong username translations before inserting/lookup up the data in the cache. BTW: a SIGUSR2 signal to the dovecot-auth process does not give any information as suggested in http://wiki.dovecot.org/Authentication/Caching. Please do not only answer to the list as I am not subscribed. Thanks. -- Gruss / Best regards | LF.net GmbH | fon +49 711 90074-411 Matthias Waffenschmidt | Ruppmannstr. 27 | fax +49 711 90074-33 mw(a)LF.net | D-70565 Stuttgart | http://www.lf.net

Re: [Dovecot] Dovecot push imap/imap notify support?

Mart Pirita <sysadmin(a)e-positive.ee> wrote: > Tried search, no luck, does the Dovecot include push imap/imap notify support? If you're looking for something iPhone-compatible, then "no." Theirs is a proprietary system which from what I've read, seems to use SMS in combination with IMAP. Wacky. (If you aren't talking about iPhone compatibility, I'm less knowledgeable, but dovecot does support IDLE-style "imap push" style notification.) Alan Ferrency

[Dovecot] mail_location and master_user rel 1.0.x
by Robert Heller 02 Nov '07

login me(a)mymail.net*theboss thebossespwd this is a great piece of software, but it has some frustrating issues. i have included my two configurations below, just FYI. the one (older) system is 1.0rc7 on mandriva 2007.0 and postfix 2.3.3 and amavisd and spamassassin and using a maildir configuration the newer system is 1.0.5 (soon to be 7) on mandriva 2008.0 and postfix 2.4.5 amavisd and spamassassin and using a maildir configuration first, i followed the instructions in this document http://wiki.dovecot.org/Authentication/MasterUsers to the letter and it works for neither the old server nor the new. specifically i was using the first example configuration. all i ever got was: Connected to mail.mailserver.com Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS AUTH=LOGIN AUTH=PLAIN AUTH=DIGEST-MD5] Dovecot ready. login him(a)mailserver.com*theboss thebossespwd login BAD Error in IMAP command received by server. and the auth_debug information was completely useless. if someone goes to the trouble of writing great examples they really should test to make sure they actually work. secondly: this configuration on the old server (1.0rc7) works fine: ## Dovecot 1.0 configuration file base_dir = /var/lib/dovecot protocols = imap pop3 imaps log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log first_valid_uid = 60000 last_valid_uid = 60000 first_valid_gid=15 last_valid_gid=15 default_mail_env = maildir:/var/spool/mail/%d/%u mailbox_check_interval = 60 maildir_copy_with_hardlinks = yes mbox_locks = fcntl umask = 0077 auth default { mechanisms = plain digest-md5 user = dovecot passdb pgsql { /etc/dovecot/dovecot-pgsql.conf } userdb pgsql { /etc/dovecot/dovecot-pgsql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = postfix group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } } } but the same configuration on the newer version 1.0.5 does not work, the problem being in mail location (note changed from default_mail_location to mail_location). so i had to make a number of changes... ##

[Dovecot] receive date wrong in outlook
by Farkas Levente 01 Nov '07

01 Nov '07

hi, we migrate from exchange to dovecot. we do it with imapsync. first we try to do it with --syncinternaldates, but this fails on many messages with invalid date, so we drop this option. unfortunately after this those users who use outlook see the received date as the date we do the migration in stead of the real received date. other clients eg webmail, thunderbird etc sees the right date. so my question what can i do? it's a dovecot bug or outlook and if outlook's bug is there any workaround fro this? thanks in advance. -- Levente "Si vis pacem para bellum!"

[Dovecot] Authentication
by Isaac Scott 31 Oct '07

31 Oct '07

Hi I am looking to use dovecot with postfix/amavis/spamassasin and would like to be able to deliver spam/virus emails into specific virtual user folders. I wanted to know if it is possible to authenticate user for IMAP and POP3 access seperately using a database? All I have seen in the documentation/wiki is a single query for authentication. Regards, Isaac
