[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)

[Dovecot] "Can't sync delivery mail"

Dovecot 1.0.3 Deliver is saying this on two specific emails. Other emails to these 2 users are going through fine.

[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.

Then, sudo chmod u+s deliver You may or may not need to do sudo chmod g+s deliver -- probably not. This is in the Sendmail - LDA part of the docs. Recent changes to Dovecot seem to have brought this to Postfix - LDA as well. Jerry

[Dovecot] dovecot + LDAP + SASL?
by hadmut＠danisch.de 02 Nov '07

02 Nov '07

Hi, I would like to setup an IMAP server with SASL and LDAP support. As far as I can see dovecot supports SASL and LDAP, but not the way I need it. If I understand dovecot correctly, it has it's own set of SASL mechnisms and uses the LDAP server just to store the plaintext password. In case of authentication dovecot fetches the plaintext password from LDAP and then performs the SASL steps internally. I need to support proprietary SASL mechanisms built into an LDAP server, which are not based on just a single password. So is there a way to configure dovecot to just pass SASL through to LDAP, allowing the IMAP client to talk SASL with the LDAP server through dovecot? regards Hadmut

[Dovecot] Successful experience with auth_winbind module
by Dmitry Butskoy 02 Nov '07

02 Nov '07

Hi, Recently the support of Samba's ntlm_auth helper was added to dovecot-auth (mech-winbind.c etc.). It is alrready in 1.1, the patch for 1.0 is here: http://dovecot.org/patches/1.0/dovecot-1.0.3-winbind.patch . It allows auth against NT or AD domain. I would like to infrom all that we successfully use this new feature during 2 month and ~300 users 24x7 (an energy power company). No any failures at all! This feature allows to specify "SPA" (Secure Password Authentication) option in OE, and to avoid explicit user passwords in mail accounts. Some random notes: - In the mixed environment (both plain and ntlm methods in use), you have to specify: mechanisms = plain ntlm login i.e. "ntlm" before "login". When sending mails, OE just catch first seen and try to use it, even if you specify to use SPA in the mail account preferences. - It seems that MS Outlook requires the specifying of password even when SPA is in effect - When OE has several identities, and one of the identities has SPA for SMTP set (outgoing mail), it wins over all another identities. - "The Bat" mailer supports NTLM for reading, not sending, and requires password too. Regards, Dmitry Bustkoy http://www.fedoraproject.org/wiki/DmitryButskoy P.S. We use NTLM only, GSS-SPNEGO still not tested.

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
