Announce: Plugin for iOS Push Email support
by Stefan Arentz 23 Sep '14

23 Sep '14

I’ve been hacking on a personal side project to support native iOS Push Email in Dovecot. This is specifically for people who are migrating their mail away from OS X Server while keeping their existing Push Email functionality. Native Push Email has some great advantages: it speeds up email notifications (usually within seconds of being handled by dovecot-lda) and it improves battery life since the native notifications flow over a single highly optimized connection to Apple’s infrastructure. Although this is at version 0.1, it is working pretty well for me and I am looking for some additional testers that are interested. Please note that it is not possible to use this project without legally running a copy of OS X Server. You can purchase OS X Server on the Mac App Store or download it for free if you are a registered Mac or iOS developer. This feature is enabled by two projects: https://github.com/st3fan/dovecot-xaps-plugin <https://github.com/st3fan/dovecot-xaps-plugin> https://github.com/st3fan/dovecot-xaps-daemon <https://github.com/st3fan/dovecot-xaps-daemon> Both projects contain a README that describes how to get things going. I have only developed and tested on Ubuntu 12.04.5 so ideally you run the same version if you are interested in playing with this project. You will need to compile some code and not be afraid of a little admin work. I am also interested in a code review. The Dovecot plugin API is barely documented and I had to guess a lot of things by looking at other plugins. An extra pair of eyes specifically on that code would be awesome. Also from a security perspective. Please file bugs! S.

> BTW: It would be nice, if I could just 'git clone' dovecot. Hi, Thomas, I happily use Felipe Contreras' excellent git-hg bridge, as I am far happier in a GIT environment than an Hg one: https://github.com/felipec/git/wiki/git-remote-hg The workflow couldn't be much easier, in particular if you set up a few aliases for the common sequences of tasks. $ hg clone http://hg.dovecot.org/dovecot-2.2 $ git clone "hg::/home/phil/dovecot-2.2" dovecot-2.2-git $ cd dovecot-2.2-git $ git checkout -b hacking $ # work... $ cd ../dovecot-2.2 $ hg pull -u $ cd ../dovecot-2.2-git $ git checkout master $ git rebase master hacking $ # more work... (OK, my workflow includes pushing too ;-) ) Hope that helps. Cheers, Phil

dsync annoyances
by Alan McGinlay 23 Sep '14

23 Sep '14

Hi! Every time I run dsync for a user against an old Cyrus server, the users mailbox in Dovecot increases by several hundred MB, these are not new emails. So the first dsync run gets the whole mailbox and subsequent runs get a bunch of duplicates or what? doveadm purge clears them all out but why is dsync behaving like this? I didn't happen in previous versions (2.2.13)

[wishlist] testsuite for sieve scripts, libsievetest
by Thomas Koch 23 Sep '14

23 Sep '14

Hi, I'm writing a test suite with Haskell for my sieve script. - Just to learn Haskell. But it might become something usable. The test suite calls sieve-test and parses the output. So it would of course be much simpler for me if the output of sieve-test would be easier to parse and if I'd know what output to expect. And it would be nice, if there would be an easy way to embed libsievetest as a C library. I looked into the source and the sieve-test binary does quite a bit of setup. This might be a nice hacking project for a beginner... BTW: It would be nice, if I could just 'git clone' dovecot. Thank you for dovecot!

doveadm with multiple instances on same machine(s)
by Will Yardley 22 Sep '14

22 Sep '14

Couple questions about running doveadm with multiple instances... I have Dovecot 2.2.13 on RHEL6 running across 3 boxes, each with a director and main instance running. When I try to lookup something on the main instance (which is handling user auth) via its auth-userdb socket directly, I get an error: # doveadm auth lookup -a /var/run/dovecot-main/auth-userdb myuser doveadm(root): Error: passdb lookup failed for myuser: Configured passdbs don't support crentials lookups When I use the default lookup map, I just get the proxy settings that are configured in the director instance's authdb. # doveadm auth lookup myuser passdb: myuser user : myuser proxy : y nopassword: y In addition, "doveadm director map" can't map the username -I get the error: doveadm(root): Error: User listing returned failure doveadm(root): Error: user listing failed [then I get the whole list, but with <unknown> for each user] The director itself doesn't have the LDAP passdb that the main dovecot instance talks to, but I have, in the director config: service doveadm { inet_listener { port = 8889 } } director_doveadm_port = 8889 local 192.168.x.x/24 { doveadm_password = XXXXXX } doveadm_proxy_port = 8888 And in the main config: service doveadm { inet_listener { port = 8888 } } local 192.168.x.x/24 { doveadm_password = XXXXXXX ## same password as above }

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 22 Sep '14

22 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Authentication using AD : bug ?
by Nicolas Cauchie 22 Sep '14

22 Sep '14

Hello, I've setup a mail server (still in test) with Postfix and Dovecot, authentication made using Active Directory. I authenticate my test user in AD well in Dovecot. However, if I change this user's password in AD, the old password still works for authentication in Dovecot and the new is working too. Is there a time to make Dovecot don't "remember" the old password or is it a bug ? Restarting Dovecot don't solve the problem. Do you already heard about this ? Please tell me what conf files you maybe need. Thanks in advance Nicolas signature -----

Re: LDAP and dovecot
by dovecot＠outputservices.com 22 Sep '14

22 Sep '14

For the record. I compiled dovecot to use the openldap libraries my openldap server uses. My email server and ldap server are on two different machines. So I just copied over my ldap libraries and placed them in the correct place and then compiled dovecot. I saw this clue in a different web page. Something about Solaris ldap libraries being bad. CPPFLAGS=-I/usr/local/openldap/include \ > LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This now allows me to authenticate with my openldap server. I am NOW able to authenticate to my ldap server. So my final configuration is: dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } /dovecot/etc/dovecot/conf.d/ldap.settings hosts = ldap.outputservices.com tls = no auth_bind = yes ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com Thank you all.

X-DOVECOT capabilities
by Timo Sirainen 22 Sep '14

22 Sep '14

Dovecot has a few hidden features currenly, which I know some webmails have been hardcoded to use. Maybe it would be nice to have these available in a bit more globally usable way and advertise some kind of X-DOVECOT capability? I don't really like the idea of having a ton of separate X-DOVECOT-* capabilities. Maybe instead just have X-DOVECOT-1 for the current functionality and when more is added X-DOVECOT-2 etc? Then describe in Dovecot wiki page what they actually contain. Thoughts? The current list of features are at least: - STATUS (X-SIZE): Sum of all RFC822.SIZEs in a mailbox. (More efficient than FETCHing them.) - STATUS (X-GUID): Show mailbox's GUID. - SEARCH X-SAVEDBEFORE, X-SAVEDON, X-SAVEDSINCE: Search with message's saved-timestamp. - FETCH X-SAVEDATE: Fetch message's saved-timestamp. - SEARCH & FETCH X-GUID: Search/fetch message GUID - SEARCH X-MAILBOX, FETCH X-MAILBOX, FETCH X-REAL-UID: With virtual mailboxes search/fetch the mail's physical mailbox name and message UID. - X-CANCEL <tag>: Stop a (long-running) command, which once in a while goes back to the main loop. For example SEARCH or FETCH.
