Looking for NTLM config example
by Mark Foley 26 Oct '17

26 Oct '17

Now that I am running Thunderbird on Linux and away from Windows/Outlook, I'd like to take another run at setting up NTLM authentication from Thunderbird to my Samba4 AC/DC. With the help of the samba maillist folks I was able to set up NTLM authentication for domain user login. I should be able to do the same for email! But, I need help. I went to http://wiki2.dovecot.org/Authentication/Mechanisms/NTLM and got lost immediately. Are "authenticaion submethods" synonymous with "password schemes"? The 7th line down says, "NTLM password scheme is required for NTLM, NTLM2 and NTLMv2.", but in the referenced link I found no reference to "NTLM password scheme". The links http://wiki2.dovecot.org/Authentication/Mechanisms/NTLM and http://wiki2.dovecot.org/Authentication/PasswordSchemes, tell you what the 4 NTLM authentication submethods are, tells you what password schemes are, tells you what the NTLM client/server handshake is, but doesn't actually tell you how to configure dovecot config files. I'm much more interested in the "how to" than in: "NTLMv2: server and client nonce, MITM can't force downgrade" ... whatever that means. Anyway, probably it's my lack of understanding terminology. I don't even know what a "nonce" is. But, I learn well from examples! Can somone please give me a sample 10-auth.conf for NTML and any other supporting settings or configs I need? My current/working dovecot settings, which have been running perfectly for well over a year now, are: $ dovecot -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/2015-08-14/57aa6ed6ae98b4c7.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/my.server.name.key userdb { driver = passwd } verbose_ssl = yes Here's what I've tried so far as 10-auth.conf: disable_plaintext_auth = no auth_use_winbind = yes info_log_path = /var/log/dovecot_info auth_verbose = yes auth_debug_passwords = yes auth_verbose_passwords= plain auth_winbind_helper_path = /usr/bin/ntlm_auth auth_mechanisms = ntlm plain login userdb { driver = passwd args = username_format=%n allow_all_users=yes } Which gives me a dovecot -n of: $ dovecot -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = ntlm plain login auth_use_winbind = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/2015-08-14/57aa6ed6ae98b4c7.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/my.server.name.key userdb { args = username_format=%n allow_all_users=yes driver = passwd } verbose_ssl = yes I configured Thunderbird for NTLM authentication, then tried sending a message, I got the following in /var/log/dovecot_info: Apr 22 01:37:57 imap-login: Debug: SSL: elliptic curve secp384r1 will be used for ECDH and ECDHE key exchanges Apr 22 01:37:57 imap-login: Debug: SSL: elliptic curve secp384r1 will be used for ECDH and ECDHE key exchanges Apr 22 01:37:57 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Apr 22 01:37:57 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<>, rip=192.168.0.58, lip=98.102.63.107, session=<xFuyOgwx9wDAqAA6> On Thunderbird I got the error, "Sending of the message failed. The Outlgoing server (SMTP) my.server.name does not support the selected authentication method. Please change the 'Autnentication method' in 'Account Settings | Outgoing Server (SMTP)'." Clearly, something is configured wrong, but I've no clue what. Can I get some advice? THX --Mark

Initialization failed: Namespace '': mkdir(/var/www/mail) failed: Permission denied
by trash＠skrilnetz.net 26 Oct '17

26 Oct '17

Hi, I'm running dovecot (v 2.2.9) on ubuntu 14.04 since a long time. I did not change any configuration lately and I'm getting the below error message. /dovecot: lda(www-data): Error: user www-data: Initialization failed: Namespace '': MKDIR(/VAR/WWW/MAIL) failed: Permission denied (euid=33(www-data) egid=33(www-data) missing +w perm: /var/www, dir owned by 1001:1001 mode=0755//) / I did some troubleshooting and I don't understand where the MKDIR(/VAR/WWW/MAIL) is coming from. Mailboxes are in /var/mail and sending/receiving emails is working as it always did. mail_location is still setup to be MAIL_LOCATION = MBOX:~/MAIL:INBOX=/VAR/MAIL/%U Why is it trying a mkdir in /var/www? Any help would be appreciated. Rgs,

haproxy ssl support
by Rok Potočnik 26 Oct '17

26 Oct '17

Even though it seems dovecot (using 2.2.33.1) supports haproxy's send-proxy-v2, it seems to lack send-proxy-v2-ssl (which also sends client's ssl state). It would be a nice feature for the backend server to identify clients so one wouldn't have to use disable_plaintext_auth on a production environment. --- haproxy.cfg frontend pop3 bind [::]:110 v4v6 bind [::]:995 v4v6 ssl crt /etc/pki/tls/private/haproxy.pem mode tcp default_backend pop3 backend pop3 mode tcp balance leastconn stick store-request src stick-table type ip size 200k expire 30m timeout connect 5000 timeout server 50000 server proxy1 [2001:db8::11]:10110 send-proxy-v2-ssl server proxy2 [2001:db8::22]:10110 send-proxy-v2-ssl --- --- dovecot.conf haproxy_trusted_networks = [2001:db8::]/64 service pop3-login { inet_listener pop3_haproxy { port = 10110 haproxy = yes } } --- It would also be nice if haproxy would support STARTTLS offloading but that's a subject for a different mailing list ;) -- BR, Rok

fts-solr: fresh start or reindex large mailboxes
by Anton Borovoy 26 Oct '17

Hi, Install solr (in the end 7.1.0) there were errors: Caused by: org.eclipse.jetty.io.EofException: Early EOF and from dovecot: Error: Mailbox INBOX: Transaction commit failed: FTS transaction commit failed: backend I could not find for a long time what the problem was and set the nginx as a proxy, and see that dovecot breaks the connect after 60 seconds. After examining the code, I found the fixed connection time: http_set.request_timeout_msecs = 60 * 1000; which is clearly not enough for large data. After searching, he also found this post https://dovecot.org/pipermail/dovecot-cvs/2015-March/025551.html 1. I think it would be a good idea to remove these settings in the configuration file dovecot.conf A bit of statistics from nginx, solr and nginx on same server (req_len == post body): 60 seconds, requests do not pass: [25 / Oct / 2017: 23: 07: 11 +0700] POST / solr / dovecot / update HTTP / 1.1 resp_time - msec 1508947631.364 req_time 86.863 req_len 171401961 499 [25 / Oct / 2017: 23: 07: 25 +0700] POST / solr / dovecot / update HTTP / 1.1 resp_time - msec 1508947645.149 req_time 74.657 req_len 70140598 499 [25 / Oct / 2017: 23: 11: 28 +0700] POST / solr / dovecot / update HTTP / 1.1 resp_time - msec 1508947888.834 req_time 90.776 req_len 205474676 499 600 seconds, requests do not pass: [26 / Oct / 2017: 04: 50: 50 +0700] POST / solr / dovecot / update HTTP / 1.1 resp_time - msec 1508968250.522 req_time 811.480 req_len 3083215798 499 [26 / Oct / 2017: 04: 51: 06 +0700] POST / solr / dovecot / update HTTP / 1.1 resp_time - msec 1508968266.432 req_time 666.089 req_len 556157906 499 [26 / Oct / 2017: 05: 06: 18 +0700] POST / solr / dovecot / update HTTP / 1.1 resp_time - msec 1508969178.612 req_time 797.983 req_len 3083215798 499 2. the index is more than 3g is transmitted painfully, can U make a queue limit on the size of the request, segment them, adjust max size of post body in the configuration file dovecot.conf thx solr: 7.1.0 dovecot: 2.2.32 server: Intel(R) Xeon(TM) CPU 2.93GHz x24, 72G RAM

authenticate as userA, but get authorization to user userB's account
by Heiko Schlittermann 26 Oct '17

26 Oct '17

Hello, given a small organization. There are *personal* mailboxes (mailbox per user, incl. subfolders et cetera). The users can share specic folders via the ACL (we call it "other users/", Dovecot calls it "shared" folder. Additionally there are mailboxes Dovecot calls "public" (we use the term "groups/"). They are not associated with a specific account, but acessible via ACL only. (Good example for the latter is "info(a)example.com") But now they're seeking for a way to implement "role" Accounts. We could create new "role" users, share the password and create an additional account within the mail client (thunderbird) they use. From users perspective it is exactly what they want. But I dislike the idea of sharing the password. Question: Is there any way to split the authentication from the authorization within common mail clients (as Thunderbird) in combination with Dovecot. That is, doing something like logging in to the account sales(a)example.com, using the credentials of the very own account (say hans(a)example.com)? - how to do it in Dovecot? (We use LDAP) - how to set up this in Thunderbird? - how to set up this in a generic MUA, as some webmail client?

I think it suffices to remove the indices for the user's INBOX, since that's the only mailbox POP3 is aware of. I'm not sure where the default index location is if you don't specify INDEX, so maybe look in your mail spool or personal mail folder for $WHATEVER/.imap/INBOX. Caches are regenerated if they go missing (unless you use mdbox/sdbox formats: *don't* do this if you're using them.) Joseph Tam <jtam.home(a)gmail.com>

Replication Issue
by Jorge Canto E. 25 Oct '17

Hello, I've been trying to set up replication, Server A is dovecot 2.2.32 (upgrade from 2.0.9) and Server B is dovecot 2.2.10, I use mysql as userdb, I don't want to replicate every user on my database only especific users so I set my iterate_query on dovecot-sql.conf.ext file; my problem: doveadm replication is not "reading" my iterate_query, it tries to replicate every user.
