HI All, I have setup my Dovecot director proxies and Dovecot backend mail stores.? I intend setting up several incoming and outgoing Exim MTA's.? I am a bit confused about what I need to run on the backend Dovecot MTA's to get the incoming mail delivered to them.? Do I need to install Exim on them or use LMTP to receive mail from the MTA's?? Also, can I directly deliver mail to the

HI All, We have a couple of dovecot director proxies and six backed mailstores each accessing mailboxes stored on five NFSv4 filsystems with about 1TB of mail on each in maildir format.? We have about 800 max users on each mailstore at peak times and performance appears to starting to degrade at these times.? The mailstores are pretty recent hardware with 64GB of RAM and 24 cores.?? The NFS

Hi All, I have dsync mirror command working between a standalone dovecot server and a backend mailstore in a Dovecot Director setup.?? Is it safe to do the dsync directly to the backend mailstore in this setup? It doesn't seem to work via the director proxy. Thanks Murray

Hi again, We have our mailboxes on several NFS filesystems mounted with the options below. ? ? 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,noatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.95,local_lock=none,addr=10.110.238) On the rare occasions that the NFS mounts hang, the system load goes through

Hi All, I am synchronizing a few hundred dovecot mailboxes with a perl script via a crontab. ? It works for a while (ie exit status=0)? but the rest then start failing with exit code 19200.?? I tried redirecting STDERR but showed nothing.? I suspect the cron job is hitting some sort of resource limit?? If I run the perl script from the command line it appears to dsync all the accounts OK.?? The

Hi All, I have a pair of dovecot director proxies and six dovecot backend mailstores using NFS v4.1 to access five filesystems on EMC VNX NFS storage. This is all working fine until I try and dsync new email mailboxes via one of the mailstores onto the NFS storage. I get major NFS lockups at random on one or more of the mailstores with none of the NFS mounts accessible on one or more of the

HI All, I have a several Exim MTA's relaying mail to a pair of director proxies via LMTP which then relayi to several mailstores via LMTP?? Incoming mail is working fine.? My outgoing mail uses LMTP also in the reverse of above.?? How do I manually test outgoing mail on the mailstores and proxies as I only have dovecot and not exim installed on them? I have the following set in

Hi All, I am having trouble removing all messages in a mailbox.?? The command below doesn't remove all the messages: doveadm expunge -u user at domain mailbox? '*' all Do I need to add .* or other? THanks Murray

Hi All, I am using dovecot in the Director setup with multiple proxy and backend mailstores and user information stored in LDAP.? I am aware users can be directed to a single backend server.? It would be useful to be able to direct groups of users to pairs of backend servers to give some fault tolerance against NFS issues and make the whole thing more scalable.??? Otherwise each backend mailstore

Hi All, I need to import mailboxes into my Director NFS setup via one of my director proxy's as doing a direct dsync to the backend mailstores appears to giving me NFS locking issues. It looks like it may be possible to do this using doveadm listeners. I have setup doveadm listeners on a test proxy and backend mailstore. I am not sure how to make the dsync proxy through to the backend

Hi All, I have my initial mailproxy setup with director through to my initial backend mailstore.? POP3 and IMAP user authentication is working ok on the proxy and the mailstore.? I just noticed when I do a "doveadm auth lookup" on the proxy it appears to give correct results but when I do it on the backend mailstore I get the error below.? Config on the mailstore below.? Any ideas??

Hi! Have been using Fedora as my dovecot server for some time and am struggling with systemd at every update. Fedora insists on setting ProtectSystem=full in both dovecot.service and postfix.service at every update of the packages. This makes my mailstore which is in /usr/local/var/mail Read-only. And this makes the incoming emails delivered through dovecot-lda disappear into /dev/null until I

Hi All, I can't get directory proxying of pop3 and imap working.? The director stuff appears to be OK - see below.?? The ldap authentication is working on the backend mail server.? I just get connection refused when I telnet to the proxy on the pop3 and imap ports.? Nothing appears to be running on the pop3 and imap ports despite the lines in the config below.? I am not sure what to do from

IMHO, you

I?m adding once a day mail delivery to my site. Messages are marked by the sender as ?overnight? or ?once a week? delivery. The way I?m planning on implementing this is to queue messages until midnight in a MySQL database. Each mailbox will be kept in two Dovecot mailstores. The first mailstore will give the users IMAP access to their mailbox. A second mailstore will hold the next day?s new

Hello, we want to migrate our dovecot 1.2 installation to verison 2.0 and want to use the director feature of version 2. Currently we have a two tier archtiecture, with dovecot proxys and a mailstore togehter with indexes on NFS. (With the common problems of this setup...) For the final setup we want to utilize the director for all protocols (IMAP,POP,LMTP,SIEVE). During the transition phase we
