Dovecot - Postfix with HAproxy

Hi Everyone, I wouldlike to set up a postfix-dovecot with HA using HAproxy but im facing issues. I've followed this documentation : http://wiki2.dovecot.org/HAProxy (pour dovecot) http://blog.haproxy.com/2012/06/30/efficient-smtp-relay-infrastructure-with… (pour postfix) Package's version : dovecot : 2:2.2.19 (>= 2.2.19 pour proxy protocol) haproxy : 1.5.14 postfix : 2.11.2-1 (>2.10 pour postscreen) A part of my configuration : ##HAPROXY #postfix listen smtp bind mail.xx.xx:465 balance roundrobin timeout client 1m timeout connect 5s no option http-server-close mode tcp option smtpchk option tcplog server tst tst.xxx:10465 send-proxy server tst2 tst2.xxx:10465 send-proxy server tst3 tst3.xxx:10465 send-proxy #dovecot listen imap bind mail.xxx.xx:993 timeout client 1m no option http-server-close balance leastconn stick store-request src stick-table type ip size 200k expire 30m mode tcp option tcplog server tst tst.xxx:10993 send-proxy-v2 server tst2tst2.xxx:10993 send-proxy-v2 server tst3 tst3.xxx:10993 send-proxy-v2 ##POSTFIX postix main.cf #Haproxy proxy protocol postscreen_upstream_proxy_protocol = haproxy postfix master.cf #haproxy 10465 inet n – n – 1 postscreen smtpd pass – – n – – smtpd S ##DOVECOT # 2.2.19 (719e7f8fd70b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.9 # OS: Linux 2.6.32-41-pve x86_64 Debian 7.9 simfs auth_debug = yes auth_verbose = yes disable_plaintext_auth = no *haproxy_timeout = 5 secs** **haproxy_trusted_networks = x.x.x.x* log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/mailbox/%d/%n mail_max_userip_connections = 0 mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_path = /mailbox/globalsieverc } protocols = sieve pop3 imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0660 user = mailboxes } unix_listener auth-userdb { group = mail mode = 0666 user = dovecot } user = root } service imap-login { inet_listener imap { port = 0 } inet_listener imap_haproxy { haproxy = yes port = 10993 } inet_listener imaps { address = * port = 993 } process_limit = 450 } service pop3-login { inet_listener pop3 { address = * port = 110 } process_limit = 180 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/star.key userdb { args = uid=5000 gid=5000 home=/mailbox/%d/%n/ allow_all_users=yes driver = static } protocol imap { imap_client_workarounds = } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol sieve { mail_location = maildir:/mailbox } protocol lda { auth_socket_path = /var/run/dovecot/auth-master hostname = xxx.yyy.com log_path = /var/log/dovecot/deliver.log mail_plugin_dir = /usr/lib/dovecot/modules mail_plugins = sieve postmaster_address = postmaster(a)xxx.yyy rejection_reason = Your message to <%t> was automatically rejected:%n%r rejection_subject = Rejected: %s sendmail_path = /usr/sbin/sendmail } With my mail client : With an IMAP connection, logs below, i don't understand why my login is empty ... dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts in 0 secs): *user=<>*, rip=mon_ip_publique, lip=ip_publique_haproxy, session= xxx With a SMTP connection, logs below, i have a timeout. postfix/postscreen[16654]: CONNECT from [my public ip]:49942 to [my haproxy public ip]:465 postfix/postscreen[16654]: PREGREET 166 after 0 from [mon ip publique]:49942: \22\3\1\161\1\157\3\3+0E\b\213\131\177\173>\r/\213\177i\223k”FjA#\144\145\153\vP\\\155HL\190 If someone could help me, thanks.

Dualstack IPv4/IPv6 setup with directors
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hi, still using 2.2.9, I've two directors, and these directors use both IPv4/IPv6 addresses. `host directors.<domain>` returns one A and AAA for each of the two directors: directors.<domain> has address 149.x.y.96 (director1) directors.<domain> has address 149.x.y.97 (director2) directors.<domain> has IPv6 address 2001:x:y:f33::5:1 (director1) directors.<domain> has IPv6 address 2001:x:y:f33::5:2 (director2) But connecting the the neighbor director gives: Oct 13 21:23:29 director1 dovecot: director: Warning: Director 2001:x:y:f33::5:2:9090/left disconnected us with reason: Invalid input: ME 149.x.y.96 9090 Oct 13 21:23:29 director1 dovecot: director: Error: director(149.x.y.97:9090/out): connect() failed: Connection refused Oct 13 21:23:29 director1 dovecot: director: Warning: net_connect_ip(): ip->family != my_ip->family Oct 13 21:23:29 director1 dovecot: director: Error: Remote director thinks it's someone else (connected to 2001:x:y:f33::5:1:9090, remote says it's 149.x.y.96:9090) I assume it's because the director uses only one (IPv4 OR IPv6) address for it's own identity, right?

Storage Design (Regligious War, Whatever)
by Kelsey Cummings 13 Oct '15

13 Oct '15

We've been running dovecot director setup using MAILDIR++ spools on NFS served by 4 (aging) Netapp clustered filers and are considering modernizing our storage. There's nothing particularly wrong with the existing storage except the age, density and power consumption don't compare well when against new systems. Refreshing the Netapps is an option but they come at a substantial cost. The last time we were looking one of the recommended hot DIY setups was Linux NFS backed by XFS on N mirrors but this predated the availability of stable ZFS in FreeBSD or Linux as well as products like FreeNAS. A FreeBSD NFS/ZFS filer on commodity hardware with zil/l2arc on a PCIe SSD seems like an attractive, affordable and easily scaled out solution which also would allow us to leverage compression at the filesystem layer. Does anyone have any experience running ZFS spool storage? If so, how do you handle DR/HA for spool storage? Thoughts on how this might compare to using DRBD? Any pitfalls to watch out for or general pointers? Suggestions on pool configuration? -K

dovecot as proxy and verification of the backends certificate
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hello, I'm using a dovecot as proxy, connecting to one or more backends. The backends use X.509 certificates. The proxy's passdb returns extra fields: user=foo proxy host=backend1.<domain> ssl=yes nopassword=y Thus the proxy connects to the backend but can't verify the backends certificate. The following comment suggests using ssl_client_ca_file for that. # Directory and/or file for trusted SSL CA certificates. These are used only # when Dovecot needs to act as an SSL client (e.g. imapc backend). The # directory is usually /etc/ssl/certs in Debian-based systems and the file is # /etc/pki/tls/cert.pem in RedHat-based systems. #ssl_client_ca_dir = #ssl_client_ca_file = ssl_client_ca_file = /tmp/certs/ca-local.pem But that does not work! Instead I've to use ssl_ca # PEM encoded trusted certificate authority. Set this only if you intend to use # ssl_verify_client_cert=yes. The file should contain the CA certificate(s) # followed by the matching CRL(s). (e.g. ssl_ca = </etc/ssl/certs/ca.pem) # ssl_ca = ssl_ca = </tmp/certs/ca-local.pem Bug or feature? Mainly I'm asking because the comments do not indicate that I should have used ssl_ca for this type of operation (dovecot as a SSL client) Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Dovecot auth-ldap ignores tls_* settings when using ldaps://
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hi, I'm using dovecot 2.2.9 (but after checking src/auth/db-ldap.c in 2.2.13 there seems to be the same bug/feature). The userdb and passdb use LDAP. All further configuration is done in auth-ldap.conf.ext. uri = ldaps://<host>/ # tls = tls_cert_file = /etc/ssl/certs/client-cert.pem tls_key_file = /etc/ssl/certs/client-key.file Dovecot ignores the tls_* options. If I use an ldap:// URI and switch on TLS using tls=yes it works as expected. But I do not see any reason why LDAPS should not read the tls_* settings. This small patch solved it for me --- dovecot-2.2.9/src/auth/db-ldap.c 2013-11-24 14:37:39.000000000 +0100 +++ dovecot-2.2.9.hs12/src/auth/db-ldap.c 2015-10-08 21:24:47.051446465 +0200 @@ -1043,7 +1043,7 @@ static void db_ldap_set_tls_options(struct ldap_connection *conn) { - if (!conn->set.tls) + if (!(conn->set.tls || strncmp(conn->set.uris, "ldaps:", 6) == 0)) return; #ifdef OPENLDAP_TLS_OPTIONS It would be great, if somebody can confirm this and if this or some equivalent patch could make it upstream.

Multiple core solr support

Is it possible to use variables, such as domain or username, in the plugin url declaration? This would allow using multiple cores to separate the stored indexes. So when my own giant mailbox gets corrupt...I don't have to rebuild everybody's... Something like url=http://mysolr.server.com:8983/solr/%u -- Daniel

fts solr ignores new mailboxes until fts rescan
by Giorgio Paolucci 13 Oct '15

13 Oct '15

Hello, on my debian wheezy installation, I implemented fts plugin with solr as indexing system. I noticed that if a user creates a new folder, that folder it is ignored by dovecot indexing until a doveadm fts rescan is performed for that user. From that time on everything works ok on that folder. As a test I set fts_autoindex=yes and put in that folder a brand new mail never indexed before. in my logs indexer-worker says it indexed 0 messages Obviously this is a major issue as users often create new folders, but a search always returns empty results. My system is a debian wheezy with dovecot packages from backports dovecot 2.2.13-11~bpo70+1. Am I missing something? Any clue would be appreciated. Thank you all in advance.
