[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] trash plugin not doing it's job

[Dovecot] Configuring Dovecot & Snarf plugin for the first time
by Jeffrey Ross 29 Oct '12

29 Oct '12

I've been using uw-imap for some time on my linux system and have been running into issues with it so I've decided to move to Dovecote, so far it seems to have solved the issues I've been having however I need/want to move the incoming emails out of /var/spool/mail/{user} in the same (or similar fashion) that uw-imap did, and I found the snarf plugin. However whenever I enable the snarf plugin using the example on the wiki page my email is not loaded and when I remove my configuration for snarf my email re-appears. Based upon what I can tell the snarf plugin is either not loading (but I see it listed in the logs) or simply not working (which is probably because its not configured properly). The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 (version supplied with Fedora). I know I'm making a newbie mistake. Any guidance would be appreciated. Thanks, Jeff dovecot -n provides the following: [root@xyzzy conf.d]# more /tmp/dovecot.changes # 2.0.21: /etc/dovecot/dovecot.conf # OS: Linux 3.4.11-1.fc16.x86_64 x86_64 Fedora release 16 (Verne) mail_debug = yes mail_location = mbox:~/mail:INBOX=~/mbox mail_plugins = " zlib" mbox_write_locks = fcntl namespace default { inbox = yes location = prefix = separator = / } namespace snarf { hidden = yes list = no location = mbox:/run/dovecot/empty:INBOX=/var/spool/mail/%u prefix = /snarf separator = / } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename snarf = = /snarf/INBOX } service imap-login { inet_listener imap { address = localhost } } service pop3-login { inet_listener pop3 { address = localhost } } ssl_cert = </etc/pki/tls/certs/XYZZY.pem ssl_key = </etc/pki/tls/certs/XYZZY.pem userdb { driver = passwd } protocol imap { mail_plugins = " zlib imap_zlib snarf" } and the logs (in debug) show the following: Oct 20 21:29:45 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19627, TLS Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt= Oct 20 21:29:46 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19629, TLS Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt=

[Dovecot] LDA without lookup as non-root?
by E.B. 29 Oct '12

29 Oct '12

Hello, I'm having some problems getting LDA to work without userdb lookups and have a few related questions. This system has all users in MySQL, each user with unique UID/GID, no local users at all. Installation is from apt-get. 1) If LDA is invoked without lookups, is it correct to assume that the "service auth" and "service auth-worker" can be completely removed from dovecot master configuration? (I have tried commenting them out and logging into IMAP, which seems to work, not sure if anyone else needs the auth service) 2) If LDA is invoked without lookups, will I be unable to use Dovecot quota plugin? Does it need to have a user lookup to get quota info? (haven't added quota support, need to take this one step at a time) 3) The interesting part -- I am invoking LDA from Maildrop. See: http://thread.gmane.org/gmane.mail.imap.dovecot/65473 So when invoked, Maildrop has already dropped to the destination UID/GID and the needed paths are available in the environment. However, using as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this: (command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) ) The UID is correct for the target user. If I add "-d $LOGNAME" to my LDA callout, I get permission denied on the userdb lookup, which I guess is another issue to work out if I want to go with lookups. But right now I am trying not to. Why does LDA seem to try for a lookup even when I follow the wiki instructions how to call it without a lookup? 3.5) Related question, my users have separate homedir and maildir, both paths are looked up by Maildrop. I think I need to call LDA with "HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?
