[Dovecot] Advice for new dovecot / imap proxy? setup
by Luca Lesinigo 23 Mar '12

23 Mar '12

Hello list. I'm planning a new mail servers for our company's customers to replace the oldish Courier-IMAP based one, we already started to deploy some mail accounts on a dovecot-2.0 server as an early test. I'd like to implement the new system with dovecot-2 (I'll probably go straight to dovecot-2.1.x) and I'd like to get it right from the beginning so I'm here asking for some advice. The issue I'm investigating right now is how to manage a single IMAP / POP / SMTP / webmail "entry point" for multiple mail servers... in other words an IMAP proxy. It would be desirable for multiple reasons: - graceful migration from the current system: we'd make the mailserver hostname point to the proxy (along with its SSL certificates) and then the proxy would route each domain to the correct IMAP non-ssl server on our LAN. No need to update customer's systems configuration and we can move one domain at a time from the old to the new server, behind the scenes - be ready for similar migrations in the future (eg. right now we're still keeping the imap servers with the qmail MTA, but we'd like to switch to postfix+dovecot in the future) - be ready for sharding mail domains on multiple IMAP servers (if/when current hardware reach its capacity or needs to be swapped out for new gear) - be ready to serve traffic over IPv6 without touching our precious mailbox servers - isolate the mailbox servers from direct external access and just run IMAP on them, let other systems run ssl, pop3, smtp, webmail, etc... Ideally the 'proxy' system would run dovecot imap and pop3 (SSL protected) and Roundcube webmail (PHP, on https) and just speak IMAP to the underlying mail servers on our internal LAN. We'd like to support all the recent IMAP goodies to make modern users happy (IMAP IDLE, LEMONADE, etc) and possibly implement Maildir quota on the new backend mailbox server to improve our operations (currently we just run du in a cronjob once a day on the current mailserver, IMAP clients including the webmail do not know about quota and thus cannot show amount of free space). In addition to that, customer's will hit the SMTP server running on that 'proxy' system and this is good to keep its configuration separated from the SMTP server of the actual mail servers (which has a different configuration and is restricted to get connections only from our MX systems and not from outside sources). I'd like to know if that plan sounds reasonable or if there's something stupid in it. Also, is the proxy going to support all kind of IMAP stuff of the backend server (IDLE, CONDSTORE, Maildir quota, immediate notification of IDLE clients thanks to linux inotify, etc...) or will it limit me somehow? thanks, -- Luca Lesinigo

[Dovecot] Dovecot 2.1.3 Proxy creates mailbox on proxy
by Ed Nitido 23 Mar '12

Hey all, I've upgraded from a working Dovecot 2.0.17 Proxy with a master user setup to Dovecot 2.1.3 and I've merged my conf settings from 2.0.17 into 2.1.3. I'm able to start up dovecot proxy and telnet localhost, however it creates the users home director on the proxy server instead of going to the backend dovecot server (which has already been successfully upgraded to 2.1.3 from 2.0.17). In my old 2.0.17, I had the entire namespace section commented out in 10-mail.conf. To achieve the same in 2.1.3 I had to remove the file 15-mailboxes.conf, otherwise my error log would have the following if I just commented out the namespace section and left that file in place: *Error: user edward(a)dev.domain.com: Initialization failed: namespace configuration error: inbox=yes namespace missing* *Error: Invalid user settings. Refer to server log for more information.* So now I'm trying to figure out why the proxy doesn't get the mail server IP from director, when doveadm has the backend server listed *# doveadm director status* *mail server ip vhosts users* *192.168.12.205 100 0* Can anyone see something I've missed? Here's my doveconf output: # 2.1.3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-openvz-amd64 i686 Debian 6.0.4 auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = plain login auth_socket_path = /usr/local/var/run/dovecot/auth-master auth_verbose = yes debug_log_path = /var/log/dovecot-debug.log director_doveadm_port = 542 director_mail_servers = 192.168.12.205 director_servers = 192.168.12.209 disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log listen = * lmtp_proxy = yes log_path = /var/log/dovecot-err.log mail_debug = yes mail_gid = vmail mail_location = maildir:%h/Maildir mail_plugins = " quota" mail_uid = vmail 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 ihave passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/home/%d/shared-mailboxes quota = maildir:User quota quota_rule = *:storage=1G sieve = %h/.dovecot.sieve sieve_dir = ~/sieve sieve_max_actions = 32 sieve_max_redirects = 4 sieve_max_script_size = 1M sieve_quota_max_scripts = 0 sieve_quota_max_storage = 0 } postmaster_address = postmaster(a)dev.domain.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 541 } inet_listener { port = 542 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director inet_listener imap { port = 143 } } service lmtp { inet_listener lmtp { port = 24 } unix_listener /var/spool/postfix/private/dovecot-lmtp { user = postfix } } service managesieve-login { executable = managesieve-login director inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service pop3-login { executable = pop3-login director inet_listener pop3 { port = 110 } } ssl_cert = </usr/local/etc/dovecot/dovecot.pem ssl_key = </usr/local/etc/dovecot/dovecot.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = uid=vmail gid=vmail home=/home/%d/%u driver = static } verbose_proctitle = yes protocol lmtp { auth_socket_path = /usr/local/var/run/dovecot/director-userdb mail_plugins = " quota quota sieve" passdb { args = proxy=y nopassword=y port=24 driver = static } } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = " quota sieve" } protocol imap { mail_plugins = " quota imap_quota imap_acl acl" } protocol sieve { mail_max_userip_connections = 10 mail_plugins = managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 managesieve_notify_capability = managesieve_sieve_capability = } protocol pop3 { mail_plugins = " quota quota" pop3_fast_size_lookups = no pop3_uidl_format = %08Xu%08Xv }

[Dovecot] dovecot 2.1.3 dsync Unexpected finish reply
by Micah Anderson 23 Mar '12

I've been moving users from one system to another by doing a dsync mirror operation. The first dsync mirror takes some time, because of the number of users involved, so I am doing an initial sync, and then I direct the users to the new location and do a final 'freshening' sync to get any changes that happened during the longer sync. The problem seems to be with this freshening sync, it seems quite fragile breaking with things like: dsync-local(user(a)example.com): Error: msg-get failed: box=Spam uid=3034

Hi Timo, hi all, after upgrading my server (both backends and load balancer) to 2.1.2 (from 2.0.17), I'm getting a log of login processes crashed in load balancer. Log lines are like: Mar 20 10:05:45 mailgw-lb dovecot: pop3-login: Fatal: master: service(pop3-login): child 27764 killed with signal 11 (core dumps disabled) Mar 20 10:06:17 mailgw-lb dovecot: imap-login: Fatal: master: service(imap-login): child 28468 killed with signal 11 (core dumps disabled) Stack trace of a crashed process is like: Program received signal SIGSEGV, Segmentation fault.

[Dovecot] Dovecot 2.1.3 on solaris with mysql - make fails
by Robert Hartzell 21 Mar '12

21 Mar '12

I'm trying to build 2.1.3 on solaris 11 11/11 with gcc 4.5.2 & sun studio 12.2 & 12.3 CPPFLAGS="-I/opt/openssl/include -I/usr/mysql/include/mysql" \ LDFLAGS="-L/opt/openssl/lib -L/usr/mysql/lib/mysql -R/opt/openssl/lib:/usr/mysql/lib/mysql" \ ./configure --prefix=/opt/dovecot \ --sysconfdir=/etc/opt \ --with-ssl=openssl \ --with-mysql make fails with both solaris standard openssl and my build of openssl. I'm also getting the same error using sunstudio mysql version is 5.1.37 The relevant output of make is on pastebin http://pastebin.com/aALHG0yL I have seen some reference to this with google but nothing thats very recent and no solutions. Anyone know how to get past this? Any tips on building dovecot on solaris? Pointers would be much appreciated. -- Robert

by Matteo Cazzador 21 Mar '12

21 Mar '12

Hello, excuse me but there is some documentation about replication now? I dont' understand where i must put the lines below (dovecot.conf? , 20-imap?) Excuse but it's not so clear for me cause i'm a new dovecot user. Another question, i use virtual users on mysql backend , so for replication i need to give ssh at every virtual users? Or i can use a only use a system ssh user? Thank's service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 mail_replica = remote:vmail at host2.example.com # host2 replicates to host1 #mail_replica = remote:vmail at host1.example.com } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail } -- Rispetta l'ambiente: se non ti è necessario, non stampare questa mail. ****************************************** Ing.
