dovecot: auth: Error: DNS lookup for xxx failed: Name does not resolve
I am sure resolving works fine. I tested this in a running mesos
container, but also in docker run[1]. I need to have the search local
option in resolve.conf.
It was actually working, until I started adding the proxy for
managesieve, but when I reverted, it still does not work. I think the
building from cache mislead me.
I suspect this is a different problem, that at some point is giving

Does nslookup work inside the container? Sounds to me like the setup
isn't working properly, but it's hard to know unless

Multiple Patitions with with mdbox
Having > 10 TByte mailstore filesystem-checks takes too much time.
At the moment we have four different partitions, but I don't like to set
symlinks or LDAP-flags to sort customers and their domains to there
individual mount-point. I'd like to work with mdbox:/mail/%d/%n to calculate
the path automatically.
How do you handle >> 10 TB mailstore?

managesieve proxying not working
I'm using roundcube webmail managesieve plugin. Webmail can login managesieve to a specific mailstore successfully without proxying. Because I have mutiple mailstores, I have to use proxying to redirect the correct mailstores just as imap/pop3.

vpopmail over NFS not seeing new messages.
Hi all.
We've just migrated our back-end NFS mailstore from FC1 systems to
CentOS4 and are experiencing problems/delays with vpopmail and user
Maildirs. IMAP is fine, it's just POP access that causes us problems.
Now, NFS mounts successfully, the clients can see /home/vpopmail and
serve content as we would expect. IMAP works perfectly and sees new
messages as soon as they're

NFS mounted IMAP dirs
Hi list,
I am trying to build an email system that is using multiple frontends, to a
clustered backend using nfs. The backend mounts his filesystems from a
central storage, and will be running active-active.
While reading through the dovecot documentation, I read that I could do
without indexes (well: use memory indexes), and could then be able to run
dovecot over NFS. Well: that was until

Local lmtp proxy on backend server
Hi Aki,
If I adapt this configuration on svr1 like this[0], should the mail not

Dovecot mailstore performance tuning
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

I am staring constantly at the same logs, this is what I get from

Local lmtp proxy on backend server
I receive a local mail when I do a 'mail test' on a backend svr1 with
this[0] configuration. However when I just add only one configuration
change 'lmtp_proxy = yes' I am getting these errors[1]. I would expect
this email to still be delivered locally, should this be working or do I
misunderstand the lmtp proxy functionality?

ENUM lookup help
Hello everyone,
I playing around with ENUM and have configured * to query a few sources
for testing purposes (fierymoon, e164.arpa, e164.org). I'd like to know
if there is a way to query these servers manually (ie outside of
asterisk via nslookup or equivalent) to find out if particular exchanges
are listed with wildcards, so as to terminate calls to those prefixes

I added this:

Which enables indeed local delivery, I also noticed this. Maybe the

jbod questions
Folks,
We are in the process of purchasing new san/s that our mail server
runs on (JES3). We have moved our mailstores to zfs and continue to
have checksum errors -- they are corrected but this improves on the
ufs inode errors that require system shutdown and fsck.
So, I am recommending that we buy small jbods, do raidz2 and let zfs
handle the raiding of these boxes. As we need more

Direct groups of users to pairs of backend servers

I am using dovecot in the Director setup with multiple proxy and

to be able to direct groups of users to pairs of backend servers to

Dsync via dovecot proxy
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
