OT - copied maildir from 2T drive to 4T drive
And it's taking up more space on the 4T drive. What did I miss?
External Program for Authentication?
Is it possible to run a bash script for authentication where a 0 exit code indicates success and a non-zero is failure? What I'm trying to do is create a shadow IMAP server that authenticates against a different server. That way my server will use the same passwords as an existing server. So what I would need is for dovecot to pass the username and password to my script, I attempt to log in remotely and if I succeed I allow access on my side. My side will be used to configure black lists and where spam is dragged from their side to my side. (I'm a spam filtering company)
Install still locks up my server
This is still broken in the 2.2.32. config.guess forks copies till the

I want to force it it maildir:/fakedir/%d/%n for this userdb only. Other
userdb has a different value.

[Dovecot] Applying a DNS RBL to deny authentication?
Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication. We do front end spam filtering for thousands of domains and I decided to advertize authentication where there is none and I accept and blackhole all authenticated email to those servers. I have harvested the IP addresses in this list that is available through an RBL. It seems to me that a nice dovecot feature would be the ability to do a black list check against IP addresses connecting and deny access if listed. Thoughts?
[Dovecot] master password
This is probably easy but how would a set a secret static master password so that if I typed it in for any login it would be happy? I can't use the * separator method in this case because it screws up squirrelmail.

As far as I remember, there had been bug reports in some versions that maybe a mixture of / and the configured separator must be used, e.g. prefix = shared. separator = . try: - -m shared.sub1.sub2.sub3 - -m shared.sub1/sub2/sub3 - -m shared/sub1/sub2/sub3 When I used Dovecot LDA, the first variant worked. Yes - I tried that and it worked with the period. However I think if I weren't using maildir format it might have failed. There should be an official way to do this.

[Dovecot] Dovecot login slow
Can't figure out why the login is slow. I telnet to port 143 on localhost. I type: 0 login user password Takes about 10 seconds and it lets me in. I'm using MYSQL and it's a small indexed database on a fast server so it's not the mysql query that's slowing it down. At least I don't think it is. But - kind of stumped. Just wondering if there's something obvious I'm overlooking.

Re: [Dovecot] Dovecot login slow
More information When i telnet to localhost on 143 it takes 10-15 seconds to log in. but When I telnet to the host name of the server it logs in instantly. Why would it be slow on localhost by fast on the server's IP address?

Re: [Dovecot] Encryption solution for messages at rest
On 10/28/2013 9:02 AM, Douglas Mortensen wrote: Hi, We have clients with various security compliance requirements. Although not required, it would be ideal to have messages encrypted at rest. We already use SSL/TLS to secure the transmission of most email. However, it would be nice to have them encrypted sitting on our server. Is anyone doing this? I think that ideally, rather than full-disk encryption, we should use an encryption that encrypts the actual email messages as they sit on our file system. This way even if we ever had our server breached by an attacker, they wouldn't be able to do anything with the messages. However, this would also mean that if the attacker can't decrypt the files, than dovecot and postfix still would need to. This means that the encryption key would need to be available to the dovecot deamon. We'd either need to have it in a file that is restricted to access only by dovecot (less secure), or use an encryption passphrase for the certificate which would have to be typed in manually each time that dovecot starts or restarts (more secure, but also more work and possibility of disruption because the server can't restart gracefully without a human being having to be present [although I don't think we have issues with unexpected restarts anyway]).

[Dovecot] Odd Feature Request - RBL blacklist lookup to prevent authentication
I would like to have a list of IPs (hacker list) that I can do a lookup on so that if anyone tries to authenticate to dovecot they always fail if they are on my list. I have the list - and the list is available as a DNS blacklist. I'd like to have it work with both local IP lists or RBL lookup. The idea is so hackers from known IP addresses never succeed. If Dovecot provides the feature I have about 1/2 million IP addresses of known current hackers to block. Anyone else interested in this?

It came down to XFS or EXT4, and I like what I've read about XFS, but am unsure how to tune it (or even if I should). I've decided to use mdbox for storage (been using maildir), and will enable SIS for attachments. So, anyone (Stan?) have any suggestions? Should I go with EXT4? Or XFS with just the defaults? Or XFS with one or more tuned parameters? Appreciate any suggestions (including links to docs dealing with tuning XFS for my mail storage conditions that are written more at the layman level) or comments from anyone experienced using both... Thanks, For what it's worth if you can afford it I'd use SSD drives. My server screams since I went to SSD.

[Dovecot] Can Dovecot authenticate against an external email server?
Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

You might do this with a script which exports the MAIL environment

It will work, we do this to set the maildir location to a custom
hashed directory and muck around with the namespaces a bit.
The script is in perl - the relevant parts look like this.
#set user's maildir location for dovecot
$ENV{'MAIL'} = 'maildir:' . getmaildir($ENV{'USER'});
$ENV{'USERDB_KEYS'} .= 'MAIL';
#pass along to dovecot's next process
exec { $ARGV[0] } @ARGV;
-K
Namespaces is something I don't understand. Still wondering what
environment variables I can pick up in this script.
What I want to do is first try /fakedir/%d/%n and if that doesn't exist
I want to go to /email/%d/%n

It would be handy (for me) if there were a userdb where a directory

userdb stat {

The idea being that if the first directory doesn't exist then it will

i dont understand why login should work with masteruser to user , when
user does not exist, would you like to get the user created on the fly
by masteruser login etc ?
The directory structure for u...@example.com exists. Just not in the
regular mysql database. If I create a fake passdb system it works:
passdb {
driver = static
args = nopassword=y
}
However - it leaves the system wide open for anyone. Basically - only
master users are going to log in and manage stored spam for regular
users. The master user will be able to spoof being the regular user to
review stored spam.
whats the problem in simply create the user mailbox?
i.e lda etc may do it on the fly be recieving a mail
http://wiki2.dovecot.org/LDA
-m mailbox: Destination mailbox (default is INBOX). If the mailbox
doesn't exist, it will not be created (unless the lda_mailbox_autocreate
setting is set to yes). If message couldn't be saved to the mailbox for
any reason, it's delivered to INBOX instead.
Maybe there's some way to have more than one mail_location? I have this
- and it's confusing:
maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs
the /fakedir directory is externally built and it has symlinks pointing
onto the /email directory where the email is stored. If I could set up a
passdb and specify a different mail_location that might solve my
problem, at least one of them.
So close - yet so far away.

[Dovecot] [OT] How do I convert maildir to bsmtp format?
Here's what I'm trying to do. I have a spam filtering operation as a front end for other servers. I've created a virtual server for spam storage where the user will be able to log in using squirrelmail/dovecot to review and release their spam. The email is stored in maildir format. Piecing it together I can use squirrelmail to pipe the email into something so that if a use finds a false positive they can hit the release button and the message is sent on to the recipient. Squirrelmail sends the message as you would receive it as stored in maildir format. I need to take this format and translate it to send it on to the user. Wondering what is the best way to do that. Something that translated it into bsmtp format would be great. I'm sure thare must be something out there. I just haven't found it yet. Thanks in advance.

(Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives.

Then if it's a false positive they would drag the message to a resend folder. I'll have something the checks the folder one a minute to pick up and resend. However What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders? Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains? One thing I can do is deliver the spam to 3 different places so it's visible on all levels. I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.

Hi Marten. There are many options that allow you to snapshop an active filesystem and guarantee a consistent backup. Eg LVM on Linux or many other OSes. WAFL on a NetApp, etc. In my experience a lot of high end mail systems store mail on the filesystem in Maildir format. Modern object stores like Scality, CouchDB or MongoDB can be very handy, as they easily allow to keep an arbitrary amount of copies of each message on This is certainly an interesting idea. different servers, you can simply add a storage node and new storage is immediately available and mailboxes aren't bound to a certain server any longer, but messages are evenly distributed across all storage nodes, thus distributing load as well. Being able to easily rebalance load would be useful. I've known of several well known companies with a lot of mail users where mail was stored on filesystems across many systems and significant imbalances developed over time. There was no easy way to rebalance them without causing an outage for at least some users. Isn't this option of big interest for every bigger mailbox provider? How hard would it be to develop? Would it be possible to get this developed on a paid basis by the dovecot core team? In my experience OSS developers are quite open to being paid to add features :) Cheers, Rob

[Dovecot] Converting from Maildir - sdbox
OK - I thought this was going to be easy. Maybe it is. I'm just not that good at reading directions. Trying to use dsync. Getting this error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Currently using maildir. The setup is as follows: mail_uid = mail mail_gid = mail mail_location = maildir:/vhome/%d/home/%n:INDEX=/imap-cache/%d-%n I don't have any namespace setting. Not quite sure what a namespace is or why I need one. This is what I'm trying to run: dsync -u m...@perkel.com backup sdbox:/email/%d/home/%n What I'm hoping to do is do a mass conversion while running. Then shut it down - do a second quick pass - and bring it up in sdbox format. Thanks in advance.
[Dovecot] DSync Namespace Frustration
In order to get dsync to work I need to set something in namespace.
Running maildir. Will this work?

[Dovecot] Maildir feature I'd like to see - SSD for newer messages
SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being migrated to larger mechanical cheaper storage. Perhaps messages over a month old? From dovecot's perspective it would sort of all look the same but maybe one a week a script would run migrating older messages to slower media. It would also make backups easier. The faster newer messages could be archived hourly. On the weekend after the archiving script was run the older message could be backed up once a week. I'm not sure what it would take to make dovecot seamlessly access email from two different locations or if this is practical. Just wanted to throw the idea out there to see if something sticks.

You can get what you want in a transparant way, independient of Dovecot. Some storage vendor (search for Fully Automated Storage Tiering - FAST from EMC or Compellent, recently bought by Dell) get what you are asking for. If the budget is low, you can achive a poor´s man storage tiering with some shell scripting, cron and soft links; Or you can look at http://code.google.com/p/fscops/ for a more mature implementation. Or just use ZFS and hybrid storage pools I wonder if there's any way to do this. Say there are two different storage devices mounted as follows: /slow-hard-drive/email-directory /fast-ssd-drive/email-directory Now suppose there were a way to join these drives so that you could access them as a single directory: /joined-drive/email-directory The Dovecot could see the joined drive but my backup/archiving scripts could see the drives independently and move old data from the fast drives to the slow drives. I think back in the old DOS days you could do that. Is there a way in Linux to do the same thing? Join two directories so as to make them look like one?

With service_limit=0 the process limits are way way too high. process_min_avail

Increases the number of connections that anvil process can handle before it

But on my DroidX smartphone one of my email accounts always shows one unread message, but I can't bring any unread messages up. It's like there's something there making it think there's a message when there isn't. The email client is K-9 mail Anyone have any ideas?

That has always been the problem when the instruction books is written by the products designer/creator, software or otherwise. This is why many commercial distributors hire outside consultants to write their instruction manuals. I was briefly involved in that field as a part time adventure. Unfortunately, the powers that be all to often considered that including all possible scenarios would make the manual overly confusing to the novice user. Plus, as both IBM and Microsoft learned the hard way, nobody RTFM anyway. I have always been of the opinion that colleges who teach technical writing should hook up with open source developers and have their students write the docs for the project and work with developers on feature requests and do tech support. It would be win/win because they would get a good education and open source software dovs would greatly improve. I had the same problem when I was a commercial software developer. I never had to learn it so I knew too much to do the docs right. However since I was doing my own support I quickly realized that if there were questions the users had that weren't covered in the docs, I added them to the docs. Saved me a lot of support effort.
[Dovecot] DSYNC needs a lot more documentation
Started looking into the dsync utility and the doc are seriously incomplete. I can of course scour the internet looking for the missing information but that doesn't fix the problem with the docs. I might try to rewrite the docs myself once I figure it out.

Or you could mention some of the things you think are incomplete. Ok - when I type dsync at the command line it says: usage: dsync [-C alt char] [-m mailbox] [-u user] [-frRv] mirror local mail_location | [user@]host | remote dsync command However the man page mentions nothing about any remote commands. There is a reference to ssh in one example but there isn't any kind of overview as to how this all ties in. Does dsync pick up information from dovecot.conf or dovecot to know where the email is an what format it is in? Does dovecot need to be running on both ends? Does this run continuously once you start it or does it need to be run once a minute? The information in the man page isn't complete enough for me to even figure out what to ask. When you write software you never have to learn it so you don't have the perspective of someone who never heard of it before and wondering what is this? I can probable figure it out if I read enough of the message from the dovecot lists but the docs should be complete enough so I don't have to do that unless I'm doing something very weird. So - ServerA is running dovecot. On ServerB I want to have a live copy so that if the drives on ServerA die I can recover on ServerB? Does it do that? I want to run dovecot on two servers so that if either server fails the other seamlessly takes over and when the other comes back up they resync as if nothing had happened. Is that possible? If so - how? If it just does backups, how is it different than rsync? Anyhow - just letting you know from the perspective of someone who knows nothing and exploring it for the first time. I wanted to say this before I learned anything more about it.

[Dovecot] Master Login using MySQL problem - %{login_domain}
Hi Timo,
Been trying to track this problem down further. The problem seems to be
related to verifying the master user failing.
My passdb looks like this:
passdb {
driver = sql
args = /etc/dovecot/dovecot-domain-owner-sql.conf
master = yes
pass = yes
}
dovecot-domain-owner-sql.conf contains:
user_query = SELECT user_name, domain_name FROM users WHERE user_name =
'%n' AND domain_name = '%d' AND owns_domain='1'
password_query = SELECT user_name, domain_name, password FROM users
WHERE user_name = '%n' AND domain_name = '%d' AND owns_domain='1' AND
'%d'='%{login_domain}'
In this example - b...@plf.net is an ordinary user. t...@plf.net is a
domain owner. Tom wants to read bills email.
The login is: b...@plf.net*tom@plf.net
This results in t...@plf.net being classified as an unknown user.

Note that the query used to determine that t...@plf.net is valid is the
password_query and not the user_query resulting in unknown user. I think
that's where the problem is.

[Dovecot] Tricky Master User Query - need MySQL help
OK - I want to do something very tricky with master users and if I get
it to work I'm adding it to the wiki for everyone to use.
So far I have a MySQL database that servers multiple domains. I can set
a flag making someone a domain owner that allows that person to become
master of that domain. Here's the query for that.
password_query = SELECT user_name, domain_name, password FROM users
WHERE user_name = '%n' AND domain_name = '%d' AND owns_domain='1' AND
'%d'='%{login_domain}'
So - here's where we get tricky.
I have another table called ownership where I have 2 fields which is a
pairing of email addresses (login_id) and domains owned (owned_object).
Data might look like this:
j...@blow.com domain1.com
j...@blow.com domain2.com
Since j...@blow.com owns both domain1.com and domain2.com I want him to
be able to log in as anyone in those 2 domains as a master user.
Examples:
t...@domain1.com*joe@blow.com
ha...@domain2.com*joe@blow.com
So the idea is to create a MySQL query so that if the master user
matches the domain part of the login user then it returns true and
allows the login.
What MySQL query will do that?
[Dovecot] Very complex Master User Examples using MySQL
For those who are interested I have posted in the Wiki examples of using master users in very interesting ways. In these example we will create 3 kinds of master users. The first will be users who can read all email for all domains. The next example will be users who can read all email for their domain only. The third example will be users who can read email of domains listed in a separate ownership table. http://wiki2.dovecot.org/Authentication/MasterUsers Go to Advanced SQL Examples at bottom Let me know what you think. In order to actually make this work you'll have to apply this patch Timo just posted: http://hg.dovecot.org/dovecot-2.0/rev/3ba227176cde

On 15/08/2010 17:10, Timo Sirainen wrote: - Dovecot uses two internal users now by default: dovenull and dovecot. You need to create the dovenull user or change default_login_user setting. Dovecot does NOT need a user named dovenull to work. The second sentence is predicated on the first and as such also falls down. Dovecot needs a user named by the default_login_user setting in order to work. Whilst this defaults to dovenull, there is nothing to stop you setting it to something else (e.g. flibble). The point is that the answer is more of a commentary and the right solution depends on the situation. Rather than try to squeeze solution summaries into every error message, I would suggest having a link (perhaps into the Dovecot wiki) in the error message, e.g. Starting Dovecot Imap: Fatal: service(pop3-login) User doesn't exist: dovenull (see http://wiki2.dovecot.org/Errors/NoDefaultLoginUser) (Note that the above URL is hypothetical.) Then have a commentary and suggested solutions in the wiki. Alternatively, the link could rooted at a notional documentation root like: Starting Dovecot Imap: Fatal: service(pop3-login) User doesn't exist: dovenull (see documentation Errors/NoDefaultLoginUser) so that users could refer to a local copy of the documentation rather than encouraging load on the Dovecot wiki server(s). Bill Maybe dovecot could use the nobody user if dovenull doesn't exist?

I don't know what dovenull user is or why it is necessary.

Timo's software standards, and mine, are higher than the average open source project. When an install id done right then you don't have to go to the wiki for anything. You run it and it just works. That's why people pay for Windows and Macs and more people use it than Linux because it just works. You start an upgrade anf click NEXT AGREE NEXT NEXT NEXT FINISH and everything just works. That's the way Linux should be. So - even though something might be a minor detail, when you get the minor details right then you get software the it just works which is in my opinion the highest thing one can say about a program. And it's who dovecot is so popular.

Quoting Bryan Vyhmeister dove...@bsdjournal.net: I have an idea for running a pair of redundant dovecot mail servers that may be odd but it might work. I'm interested in any thoughts on the topic. Would it work to run 'dsync mirror' every minute against either mdbox or sdbox mailbox on a dedicated network connection between two (or potentially three or four) mail servers? I'm trying to avoid using a NAS/SAN or some other dedicated NFS server in a simple environment with a limited number of users. Everything else about the systems could be identical. Both could receive mail using Postfix with dovecot LDA. Thank you. Bryan

But the %{login_domain} evaluates to an empty string as you can see from
the results of the debug.

Interestingly %{login_user} doesn't work either returning an empty

Actually - spoke too soon. %{username} returned the wrong value. It
returned that name part of the master user.
