On the other hand, you don't seem to have that problem, so things work
out maybe.

It's cleaner to know the future and ban the right things at the right
times, but is there real harm from people trying bad logins from
different IP's and you just wait for fail2ban to block each one?  Your
log snippet covers 151 minutes, even fail2ban would normally have
unjailed ip's after that much time.

That 10-auth.conf is actually meant to be edited. most distros should

Re: Storage upgrade maildir suggestions?

Hi,

we start to run out of diskspace soon as our users start to keep mails
for longer time periods. That's fine, but space consuming.

The maildirs are about 1 TB in total, and not long ago we enabled zlib
which is very nice.

Now I have some thoughts about the next steps:

a) Migrating the whole system to a new server with more storage?

b) Install a virtual server for the mailsystem and an extra storage
system may be NFS?

c) Stay with the current server and move all mails to a bigger NFS 
storage.


The last option c) would be the most easy one for me as I currently 
have

NFS space.

Any thoughts? Hints regarding the NFS storage? Pros Cons?

I have seen the dovecot wiki on NFS already and for now we will stay
with one single dovecot server.


FC or iSCSI as storage.

and always have a lvm layer between your HW and the FS. that way you can 
easily attach

more disk to the stripe set and grow your storage that way.

Re: RFC: HTTP based storage API

that sounds like s3 API based backend.

also note that dovecot comes with some "non local mail storage plugins"
in the commercial part:

```
In this release, we support Windows Azure, Amazon S3, Scality and
Dropbox systems.
```

so that should come close to what you want. for a local version you
could use e.g. radosdb/ceph or riak. both can provide the s3 API for
you.

True ... but that might be the hook point you can use for your more

mdbox and so on. the api towards dovecot should be the same.

2. especially when you want to deleting mails in the mbox file it is a
   lot of rewriting data. compared to just unlinking the files.

 And my question was how to properly read and write from/to mbox files 
 which are used by dovecot.

Through the imap protocol or at least the same locking mechanism
configured in dovecot.

 Really? I do not think so! Having half of million (small) files in one
 directory is killer... which eats caches and slow down access time.
 Even listing such directory (without reading file contents) consume lot
 of CPU cycles...

so what?

1. modern filesystems
2. dovecot's caching

313k mails in single mailbox and no problems at all.

 PS: I'm not subscribed to this list, so please CC me!

you should change that. it isnt that high traffic.

 What is correct way to read those mboxes? From wiki page [1] I read that 
 I should ignore first message in mbox (which contains X-IMAPbase header) 
 and mbox file is in mboxcl2 format.
 
 And what is correct way to modify that mbox file (which is used by 
 dovecot imap)? I would like to configure mutt on server to directly 
 access those mbox mailboxes without need to use imap protocol (over 
 localhost). It is possible without any data/message damage?

IMHO ... If you start a new mail server now ... Maildir is a better
format.

 Ah, sorry for taking your time on an old bug.  For most of my servers, I
 try to use the RHEL/CentOS-provided packages where practical (because
 with over 100 servers running a wide variety of services, building
 everything from source takes more hours than I have in a day).  The
 hazzard of course is chasing already-fixed bugs from time to time.
 
 I also understand Red Hat's stability approach, where they tend to
 stick with a given upstream version and just patch it; few Open Source
 software developers have the time to maintain bugfix-only branches for
 the lifetime of a RHEL major version, and new features tend to mean new
 bugs as well.
 
 Thanks for taking the time to point out the fix.  I was hoping to have
 time this weekend to try the latest Dovecot release, but hadn't yet done
 that.  I have opened a Red Hat bug to try to get this patch applied.

 ..
 
 I have a requirement to have read-only to a mailbox. I have been
 researching through the wiki, the mailing list archives and good old
 Google. There was a number of similar questions with no real
 definitive answer.
 
 Option 1: ACL
 This can work, but not if the mailbox(s) can change without you
 knowing how. I.E. a online read-only archive of someone else's
 mailbox. There is no wild-card or recursive ACL options. Rsync style
 backups don't allow for easy creation of custom ACL files per
 mailbox.

acls are stored in dovecot-acls files either inside the mailbox or in
/etc/dovecot. so you can preserve them easily with rsync style backup.

  2) Dovecot needs write access to CONTROL and INDEX files.
 This lead me to using the CONTROL and INDEX options on the
 mail_locaiton. Setting these to the original 'rw' mount and the rest
 to my 'ro' bind mount. Again, messy but do-able.

Just for the record: you can configure CONTROL and INDEX seperately. see below.

my solution for a similar problem:

[[[
namespace public {
   separator = /

   # Mailboxes are visible under shared/u...@domain/
   # %%n, %%d and %%u are expanded to the destination user.
   prefix = archive/

   # Mail location for other users' mailboxes. Note that %variables and ~/
   # expands to the logged in user's data. %%n, %%d, %%u and %%h expand to the
   # destination user's data.
   location = 
maildir:/srv/mail/archive:INDEX=/srv/mail/%u/shared/%%u:CONTROL=/srv/mail/%u/shared

   # Use the default namespace for saving subscriptions.
   subscriptions = yes

   # List the shared/ namespace only if there are visible shared mailboxes.
   list = children
}
]]]

only my mail archive user can deliver mails into that namespace (via ACL (p)).
all other users only have read permissions, as index/control are per user, each 
user can have their own
flags (like seen).

shouldnt this give you exactly what you want?

 This seems to be solving a different problem to mine. I need,
 something like a mirror of accounts, on a separate server that gives
 the user read-only access to the content.
 The data is not public. I should only be accessible to the authorised user.
 The input to this archive is the 'original' live maildir, so I do
 not have control over the creation of folders, etc. This causes
 problems with dovecot ACL inheritance as the mailbox is not created
 via the dovecot server with the ACLs.

you can specify default ACLs in /etc/dovecot/acls?

i suggest playing around with mail_debug and see what ACL files it tries
to load.

and the name public for the namespace is confusing. it is not really
public. only people with ACL entries can read from it. (yes i tested
this)

but unlike shared namespaces it is not user specific (e.g.
shared/f...@bar/INBOX)

Re: [Dovecot] Help needed with plugin - Read Only access to IMAP mailbox

 I did try this. Again, the issue being that they are not inherited to
 sub-folders, so a ACL for the INBOX is not used for all folders. You
 need a global ACL file named for each folder name. So if a client
 creates a folder called My banana photo collection you would need a
 file /etc/dovecot/acls/My banana photo collection with something
 like authenticated rl
 
 It is not possible to have a global ACL for every possible folder name.

to quote http://wiki.dovecot.org/ACL :

[[[
Every time you create a new mailbox, it gets its ACLs from the parent
mailbox. If you're creating a root-level mailbox, it uses the
namespace's default ACLs. There is no actual inheritance, however: If
you modify parent's ACLs, the child's ACLs stay the same. There is
currently no support for ACL inheritance. 

The default ACLs are read from dovecot-acl file in the namespace's
mail root directory (e.g. /var/public/Maildir).

 Subject: [Dovecot] Mobile phone client - first access
 To: dovecot@dovecot.org
 
 Ladies and gentlemen, good morning!  With my first post to the list,
 may I begin by saying how impressed I have been by Dovecot's
 performance on our Debian server.  We've configured it to run with
 Exim and Fetchmail, using Dovecot to manage professional and
 domestic emails for a small home office, serving a number of Windows
 and Linux clients both on the internal network and, when working
 overseas, via SSH tunnels back to the Debian server.  Dovecot's
 performance has been, simply, rock-solid; a very impressive piece of
 work by Timo and all those supporting him.
 
 My ordinary mobile phone - a Sony Ericsson C510 - includes an email
 client with IMAP capability (and none, TLS, or SSL encryption).
 Configured to access our server across the mobile carrier's network,
 the results surprised me; they were not what I expected.
 
 The first surprise was, it worked.
 
 More seriously, the messages it retrieved were not what I expected;
 the phone received around 58 messages, but from the 'inbox', the
 'junk' box, and a couple from a 'project' box.  I had expected to
 only retrieve the messages that were in the 'inbox'.  How does
 Dovecot 'decide' what messages to give the phone client?  [I think I
 may have the wrong 'mental model' of what should have happened, and
 would appreciate being put right.]  Is it possible to configure
 Dovecot to only serve specific boxes?  The mobile phone client is
 extremely simple - it does not have the facility to 'browse' the
 folders, it only has an inbox, sentbox, etc; I have wondered whether
 there might be a 'jar' email client that is richer, and which might
 help - I will look for something anyway.
 
 But I was impressed that my mobile phone could check our home and
 office email while offsite; if I can get that working it will save
 having to fire up the laptop at each opportunity.
 
 Thanks very much for reading this far, and, also, thanks everyone
 who takes the time to contribute to the list,

your phone decides.

you should check if the software on the phone honors the server side
subscription list or has a local one.

 would benefit the most from an SSD because reads would be extremely
 fast while minimal writes (comparatively) take place due to the way
 mdbox is structured. I guess what I'm saying is that even if the SSD
 has average to slow write speeds the fast read speeds would make a big
 difference in many operations. Any thoughts? Alternately, run either
 option on a hard drive with indexes on fast flash memory. Anyone tried
 something like that? Thank you.

 the folder is not present.
 
 The folder is created, but no line about it is present in subscriptions
 file. So, the folder is not viewable.
 
 And we can't create it in a IMAP connection because it exists... (but
 not visible).
 
 Thanks for your help.

how about subscribing that folder? autocreation doesnt imply
autosubscribe. i am sure users might be a bit angry if you autosubscribe
any folder of theirs, esp. if they read their mails via a mobile device.

 What Dovecot version? v1.0.8 fixed one bug that caused this.
 
 1.0.7 - will update as soon as gentoo's portage includes 1.0.8..
 hmmm though it seems to have skipped it and gone to 1.1 beta:
 
 *  net-mail/dovecot
   Latest version available: 1.1_beta11
   Latest version installed: 1.0.7
   Size of files: 2,594 kB
   Homepage:  http://www.dovecot.org/
   Description:   An IMAP and POP3 server written with security 
 primarily in mind
   License:   LGPL-2.1
 
 Do you do the ebuilds yourself for gentoo? I think you should update the 
 Description - makes it seem like dovecot is just about security and not 
 performance when that isn't the case!

there is an 1.0.9 ebuild which can be installed with:
emerge =dovecot-1.0.9

 It could also be dual-licensed to both to maximize the distribution

GFDL has some sucking part about the license when using parts of the

  i would rather say use the latest package that comes with your distro.
  for most users this is a better decision. admins often forget to check

 With dovecot, this is a recipe for desaster.

i would rather say depends on the distro and the setup. for many users
it might work very well. and i would rather have an older version with
security fixes than and maybe less old version without.

you have not configured the dict server. just a dict client.

 I have dovecot running with sieve performing vacation autoreply.
 
 Can sieve do sql lookups for vacation messages instead of having to do flat

 No, unfortunately. To my knowledge, there is also no sieve extension 
 that specifies such behavior. The only proposed extension that has the 
 ability to do a background lookup is extlists, but that has nothing to 
 do with retrieving arbitrary strings from a database and will not be 
 useful for your purpose. If you feel that is might be commonly desired 
 feature of the sieve language, you could ask around on the 
 [EMAIL PROTECTED] mailing list whether such an extension would be 
 viable and whether someone is willing to adopt the responsibility to 
 write a proper specification.
 
 And then it still needs to be implemented of course... :)

or just implement a webinterface that allows editing the values in the
DB and afterwards dumps a new vacation script for the user to disk

 a simple

 fixes the problem.

the real solution would be to copy the config.rpath [1] from your distro
into the source dir. this requires the gettext devel files to be
installed.

now the question is when using the 1.1b9 tarball.
why do you run autogen.sh at all?
