[Dovecot] Local node indexes in a cluster backend with GFS2
by Aliet Santiesteban Sifontes 15 Nov '10

15 Nov '10

Hi, all this days I'm testing a dovecot setup using lvs, director and a cluster email backend with two nodes using rhel5 and gfs2. In the two nodes of the email backend I configured mail location this way: mail_location = sdbox:/var/vmail/%d/%3n/%n/sdbox:INDEX=/var/indexes/%d/%3n/%n /var/vmail is shared clustered filesystem with GFS2 shared by node1 and node2 /var/indexes is a local filesystem at the node, so each node has his own /var/indexes stuff on ext3 and raid1 for improving performance, I mean each node a different /var/indexes of its own. Now, if the director was using node2 for the email for user1 and I removed node2 now all the connections for that user are redirected to node1, that node has its local /var/indexes, when this ocurr I can not see the emails that in fact are in the mailboxes, I guess should be indexes not current with the user mails. Is supposed indexes to be rebuilt automatically when the node switches?? Or I have to configure the indexes in the shared storage so the two node update the information concurrently? I will appreciate your help... best regards

[Dovecot] Is Dovecot Director stable for production??
by Aliet Santiesteban Sifontes 14 Nov '10

14 Nov '10

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

[Dovecot] Daemon will not start, invalid argument in stat of base_dir (error within)
by Frank Collette 13 Nov '10

13 Nov '10

Running CentOS 5 and Dovecot 1.2.16 Receiving error: Error: stat(/var/run/dovecot) failed: Invalid argument Fatal: Invalid configuration in /etc/dovecot.conf I've put the default dovecot.conf in place and still get the same thing. I've tried removing the /var/run/dovecot folder and letting it re-create it with no success. It creates the /var/run/dovecot folder but that is all. I've tried setting the base_dir to /tmp/dovecot to test and get the exact same error. I'm at a loss as are many other people so am hoping someone here might be able to help!

[Dovecot] dovecot sieve enotify question
by Robert Schetterer 13 Nov '10

13 Nov '10

Hi, sorry not dovecot but heres the question is it possible to use dovecot sieve enotify not only for notify mail i.e arrived but with add the incomming mail as attachment to the notification ? i.e. i have found a example require ["enotify", "fileinto", "variables"]; if header :contains "X-Spam-Flag" "YES" { set "from_addr" "admin(a)example.com"; set "subject" "Spam"; notify :message "${from_addr}: ${subject}" "mailto:user@example.com"; } is there a way to add the orginal mail as attach to the notfication mail , and finally perhaps delete it this would like a redirect/forward with right from_addr ( which should always be the default mailboxname/emailaddress -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] squirrelmail inbox empty
by Paul Cartwright 12 Nov '10

12 Nov '10

I am running Dovecot + Postfix +Squirrelmail on Debian Lenny.Fetchmail pulls the mail, dovecot spreads it around. I had squirrelmail setup & I tested it from within my router ( internal LAN). yesterday I had to go babysit my grand daughter, and I setup port forward for IMAP port 143, and I can use squirrelmail through firefox on my laptop. All the other folders have all the mail from the time I left til now. Yesterday I was reading inbpox mail, deleted a few junks, etc, and suspended my laptop. When I came back my inbox was empty, and I've never seen any more messages in it. I know I should have LOTS of older+new messages that don't get filtered. Unfortunately ssh doesn't seem to work from this linux side, it does from the windos side ( ssh keys?), so I can't get in to look at the logs.. I already removed ( I think ) all the inbox index files... & restarted, but no joy. I am not sure if it is getting filtered from the ibox, or if I just can't see it. I am not familiar with how squirrelmail works with local IMAP folders, so I am unsure where to look or what logs to browse. I will be home later today. suggestions clues or otherwise?? -- Paul Cartwright
