[Dovecot] Is Dovecot Director stable for production??
Today I will try Dovecot Director for a setup using a Cluster Backend with GFS2 on rhel5, my question is if is Director stable for use in production for large sites, I know is mainly designed for NFS but I believe it will do the job also for a cluster filesystem like GFS2 and should solve the mail persistence problem with a node and locking issues. I plan to add a layer behind a load balancer to do the stuff, I will appreciate if you guys can point me to best practices in configuring the director, or how the thing works since is new for me, I have seen the example conf but I don't have clarity in some of the concepts and the wiki is empty. I use 2.0.6, thank's for a great job with dovecot. best regards, Aliet

Ok, I answer to my self what I did: In /etc/dovecot/dovecot.conf protocols = imap pop3 lmtp sieve In /etc/dovecot/conf.d/10-auth.con disable_plaintext_auth = no Removed comment to !include auth-static.conf.ext In /etc/dovecot/conf.d/auth-static.conf.ext passdb { driver = static args = proxy=y nopassword=y } In /etc/dovecot/conf.d/10-master.conf to fix perms service auth { ... mode = 0600 user = dovecot ... In /etc/dovecot/conf.d/20-lmtp.conf lmtp_proxy = yes In /etc/dovecot/conf.d/10-director.conf director_servers = 172.29.9.25 172.29.9.26 director_mail_servers = 172.29.9.10 172.29.9.11 director_user_expire = 15 min service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0666 } unix_listener director-userdb { mode = 0600 } inet_listener { port = 4000 } } service imap-login { executable = imap-login director } service pop3-login { executable = pop3-login director } # Enable director for LMTP proxying: protocol lmtp { auth_socket_path = director-userdb passdb { driver = static args = proxy=y nopassword=y port=24 } } Both backend configured and working using ldap, with this director config is working but I still have a problem... if I run command doveadm director map I get user mail server ip expire time <unknown> 172.29.9.11 2010-11-13 17:43:31 lmtp, imap and pop director working but in the list the user appears as unknown, how tofix this?? any ideas?? 2010/11/13 Aliet Santiesteban Sifontes <alietsantiesteban at gmail.com>> Today I will try Dovecot Director for a setup using a Cluster Backend with > GFS2 on rhel5, my question is if is Director stable for use in production > for large sites, I know is mainly designed for NFS but I believe it will do > the job also for a cluster filesystem like GFS2 and should solve the mail > persistence problem with a node and locking issues. > I plan to add a layer behind a load balancer to do the stuff, I will > appreciate if you guys can point me to best practices in configuring the > director, or how the thing works since is new for me, I have seen the > example conf but I don't have clarity in some of the concepts and the wiki > is empty. > I use 2.0.6, thank's for a great job with dovecot. > best regards, Aliet >
