[Dovecot] Create userdir on dovecot login
by Andreas Cieslak 22 Sep '11

22 Sep '11

Hi List, I am trying to set up automated userdir-creation on login via squirrelmail or email-client with a dovecot backend. The users are first imported on an openldap directory on the same server as the dovecot runs on. Authentication on the dovecot mail system via pam_ldap works properly. Tried already to integrate some advices from the dovecot wiki like Passdb { Driver = pam args = session=yes dovecot } But the homedir creation works only when the user logs onto the machine. When I try to log in via Squirrel on the dovecot no homedir is created and there is following message in the logs: auth: Error: pam(cieslak,193.175.157.121): pam_open_session() failed: Permission denied I think its something about the user rights, but dont really know where to search for the needle Here is the config of my environment root@server:/home# dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.2 auth_debug = yes auth_mechanisms = login plain auth_verbose = yes first_valid_uid = 1000 hostname = server info_log_path = /var/log/dovecot-info last_valid_uid = 10000 listen = * log_path = /var/log/dovecot mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Maildir mbox_write_locks = fcntl passdb { args = session=yes dovecot driver = pam } postmaster_address = mailaddress service auth-worker { group = shadow user = $default_internal_user } service auth { user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 0 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_ca = </usr/local/etc/dovecot/ca ssl_cert = </usr/local/etc/dovecot/crt ssl_key = </usr/local/etc/dovecot/key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } dovecot --version 2.0.13 The configuration of the pam module /etc/pam.d/dovecot looks like @include common-auth @include common-account @include common-session The common-session has the line session required pam_mkhomedir.so skel=/etc/skel umask=0077 I would appreciate any hints.

[Dovecot] Webmail architecture : questions about cache and storage backend
by forumer＠smartmobili.com 22 Sep '11

22 Sep '11

Hi, I have some questions about dovecot-2.1 and need some advice about software architecture. My company plans to develop a kind of Document Managing System (DMS) and one of its module is a webmail that is currently in a pre-alpha stage (if you are curious you can have a look here http://kairos.smartmobili.com/ but don't be surprised if it doesn't work and please do not use IE for now). From my personal analysis that I am sure is incomplete we have the following options to handle emails storage and cache: 1) Do not use a cache and rely on dovecot performance to retrieve email's header in real time. Actually don't know if it's that simple because we might need to have a transformed version of emails to be able to display them more easily in the webmail. In this case this option is not really possible. 2) Use new dovecot-2.1 imap backend and develop a kind of dummy imap server listening to a custom port and storing emails inside a mongoDB database. Advantage is it allow replication very easily. 3) Wait for dovecot2.x to implement a NoSQL storage. Will it happen soon ? If you have other suggestions or ideas I would be happy to hear them.

[Dovecot] Help restoring imap mail
by Knute Johnson 22 Sep '11

22 Sep '11

My mailserver blew up today with a power hit. I've created a new server and have dovecot running and I want to restore my mail. I have a copy of the file that was in /var/mail. I set the new dovecot config up the same as the old one and copied the mail file over. I can see the INBOX mail but none of the rest of it. I'm running 1.2.15 under Ubuntu server 11.04. I'm using Thunderbird as my client running on XP. Any help would be greatly appreciated. Thanks, -- Knute Johnson

[Dovecot] Sieve: Vacation, handle and variable
by René Neumann 21 Sep '11

21 Sep '11

Hi *, I am adding a generic way for vacation-replies in my sieve setup. There I set the handle and the reason using variables (see end of mail). My simple question now is: Though variable expansion is not done for subject and reason, is it done for the handle? Because else there seems no way in configuring the vacation action via variables. I tried to read the code for this extension, but ... well ... the whole sieve implementation is way more complicated then I figured ^^. Thus I take the question to the list. Thanks, René ----- default.sieve ----- require [..., "include", "variables"]; # set this to the text you want to get included in the vacation-mail global ["vacation", "vhandle"]; set "vhandle" ""; set "vacation" ""; [...] include :personal "vacation"; ----- vacation.sieve ----- require ["variables", "include", "vacation"]; # this is set in the including script global ["vacation", "vhandle"]; if string :is "${vacation}" "" { return; } # ensure we have a handle if string :is "${vhandle}" "" { set "vhandle" "${vacation}"; } if header :matches "subject" "*" { set "sbj" "Out of office [was: ${1}]"; vacation :addresses [...] :from "..." :days 7 :handle "${vhandle}" :subject "${sbj}" "${vacation}"; } -------------------------

[Dovecot] About using Dovecot indexes with Thunderbird/kmail
by Anton Aylward 21 Sep '11

21 Sep '11

I have Dovecot running well on my Mandriva mail hub, handing out IMAP to the household LAN. This is 1.2.15. Eventually I'll upgrade the OS and get 2.x, but this is working fine. So this question is really about the mail readers I use and how they make use of Dovecot. I have Thunderbird on my laptop and KMail2 on my desktop. Dovecot indexes. GOOD! The trouble is that the mail readers want their own indexes :-( I wish that Thunderbird would NOT index mail on my laptop, but it does. I wish Kmail2 would not use nepomuk/akonadi to index the mail but it does. Why can't they both believe the indexes used by Dovecot? Is this an unreasonable request? -- "We stand behind all of our products, except for the manure spreader." -- Corporate motto of an equipment manufacturer
