Postfix Dovecot LDAP setup
by Leander Schäfer 22 Jan '15

22 Jan '15

Hi, since days I'm trying to substitude my SQL based Postfix/Dovecot mail server by a LDAP based setup. Everything seems to go smooth so far - thanks to the many how to and Dovecot wiki. Unfortunately I'm struggeling, since I have to create individual a LDAP schema which suits the currently used LDAP structure. The current tructure looks like this: => dc=MyDomain,dc=TLD ==> ou=People ===> uid=User-1 ====> ou=mail ===> uid=User-2 ====> ou=mail ... and so on ... Within ou=mail should be the individual mail account(s) information of a user. So in the end I want to add a(nother) mail account by something like this: cat << EOF > ./newUser.ldif dn: mailAddress=Test(a)Domain.TLD,ou=mail,uid=User-1,ou=people,dc=MyDomain,dc=TLD objectclass: top objectclass: mailAccount mailAddress: Test(a)Domain.TLD noMailPassword: {SSHA}SomePassword noMailAccountStatus: active [...] EOF Therefore I setup a LDAP schema like the following, but it seems to ignore the attributes "MailPassword" and "noMailAccountStatus". Why? I don't understand what I'm missing here on my objectclass? ;/ # ====================== LDAP schema ======================= # # # OID Macros (10001 should be IANA-registered) # objectidentifier nameSpace 1.3.6.1.4.1.10001 objectidentifier mail nameSpace:1 objectidentifier objectClassAccount mail:1 objectidentifier objectClassAccountInfo mail:2 # # Attributes: objectClass[NAME]:1.[SERIAL] # attributetype ( objectClassAccount:1.1 NAME 'mailAddress' DESC 'The hosted mail addresses' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26{256} SINGLE-VALUE ) attributetype ( objectClassAccount:1.2 NAME 'MailPassword' DESC 'The hosted mail password' EQUALITY octetStringMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40{128} ) attributetype ( objectClassAccount:1.3 NAME 'MailAccountStatus' DESC 'The status of a user account: active, noaccess, disabled, deleted' EQUALITY caseIgnoreIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE ) [...] # # Objects: objectClass[NAME]:2.[SERIAL] # objectclass ( objectClassAccount:2.1 NAME 'mailAccount' SUP ( top ) STRUCTURAL DESC 'Mail account' MUST ( mailAddress ) MAY ( MailPassword $ MailAccountStatus ) ) # ====================================================== # Thanks Best Regards, Leander

hello. Today I had a problem (core dumped) in a dovecot installation update yesterday. After many hours I found that when one settings "protocol imap" the option "replication" causes (core dumped). In this server settings "replication" was removed leaving only the "protocol imap" (my error) I send my documentation error so they can add a validation and not generate a Fatal Error end users.

Trying to get lda to deliver into public sub-sub-folder
by Claudius 21 Jan '15

21 Jan '15

Hi, I have this setup: recipient_delimiter = + mail_location = sdbox:~/sdbox namespace { type = public prefix = public/ location = sdbox:/home/vmail/shared/sdbox subscriptions = no } Postfix delivers via dovecot-lda: dovecot_shared unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/bin/env HOME=/home/vmail/shared /usr/lib/dovecot/dovecot-lda -f ${sender} -m ${user}/${extension} This works fine, ACL are manually defined and also work great. If I want to deliver into a subfolder I tell postfix to rewrite it to: folder+subfolder@dovecot_shared This is how it looks like: /home/vmail/shared/sdbox/mailboxes/{user}/{extension}/dbox-Mails But with this setup I couldn't get it to deliver into a subfolder of "subfolder/extension". Is it at all possible? Changing the HOME directory does not work because of the sdbox folder structure. I tried to generate a service for each subfolder like that: -m ${user}/subfolder/${extension} But when I did not have an extension I got: save failed to open mailbox {user}/subfolder/: Invalid mailbox name even though it exists. I think it doesn't like the trailing slash, but I don't know how to get rid of it. Hope I explained it well enough :) Regards, Claudius

Shared folders - Namespace definition
by Peter Hodur 21 Jan '15

21 Jan '15

Hello, I'm trying to configure shared mailboxes with ACL. My problem is FS layout. Our maildirs is completely outside of home dirs (home dirs is on pure SSD zpool, maildirs on separate HDD zpool). We are using checkpassword auth, which sets mailbox_location for each user. Layout is following: maildirs: /dpool/mail/maldirs/user-uuid/ home is: /dpool/mail/home/user-uuid/ index & control is under home: /dpool/mail/home/user-uuid/[index|control] the problem is how to specify path in NAMESPACE definition. I can use %% variables, but maildirs is not under home and also does not have "fixed" structure (so I can not use %%u for example). Is it possible to for example set some special env variable from checkpassword and than use it in namespace definition like home variable? Or can someone help to find the code in dovecot, which evaluates namespace location patter so I can patch it? thanks Pete

UID changes every few seconds
by Adam Przybylski 20 Jan '15

20 Jan '15

Hi, I'm trying to use Gmail-style conversation view, as described in http://wiki2.dovecot.org/Plugins/Virtual#Examples >From a client based on Roundcube Framework I'm fetching message list from "virtual/INBOX" folder and that works fine to some degree, but the problem is that every few seconds or so (probably when new message is delivered or bounced on the mail server) UID of those messages changes. When I'm trying to display the details of given message (fetch body by UID), I'm getting an error because message with given UID do not exist on the server. When I only refresh the list (fetch messages one more time) and compare UIDs of the same messages between fetches, there are completely different numbers - growing every fetch. When I switch from virtual folder to real INBOX everything works fine, UID stays unchanged over time. Is this the intended behavior for virtual folders or some kind of bug? Or am I doing something wrong? I'm using Dovecot 2.1.7 on Debian GNU/Linux 7 (wheezy). The output of dovecot -n is attached. Thanks in advance, Adam

Hi! My "no" referred to the fact that I had not read the article before. =D Thanks for linking it - I'm sure it will be very useful.

Outlook and TLSv.1
by Oliver Welter 20 Jan '15

20 Jan '15

Hi Folks, after adding TLSv1.2 to by TLS options a lot of Outlook users complaint about connection errors, openssl s_client and Thunderbird works fine. I found some posts about this but none of them had a real solution on this - I meanwhile disabled TLSv1.2 which made the Outlook users happy. I run dovecot 2.2.13, OpenSSL 1.0.1j 15 Oct 2014 ssl_cert = </var/qmail/control/servercert.pem ssl_cipher_list = ALL:!EXPORT:!LOW:!MEDIUM:!aNULL:+RC4:@STRENGTH ssl_dh_parameters_length = 2048 ssl_key = </var/qmail/control/servercert.pem ssl_protocols = !SSLv2 !TLSv1.2 The certificate is from Comodo using sha256. Any idea? Oliver -- Protect your environment - close windows and adopt a penguin!

by ML mail 19 Jan '15

19 Jan '15

Hello I am using the quota warnings e-mail feature of dovecot to warn users at 80% and 95%. The issue here is that I have one use who his mailbox is now back down to 20% but he still receives the 95% mailbox full warning mail. Any ideas what could be wrong or what to do? My dovecot config of the mailbox server can be found here: http://article.gmane.org/gmane.mail.imap.dovecot/80823 Regards ML
