Any comments on this? Anyone with a working date extension?
  
Most curious. That version should support the date extension as 
indicated by the binary containing the corresponding symbols. Did you 
set sieve_extensions in your configuration perhaps. Are you sure that 
you are using the correct instance of the Sieve plugin? Showing your 
dovecot -n output may help us pinpoint the error.

Yeah, it's this one. I'll probably revert it soon. I did it mostly while
trying to fix istream-zlib bugs, but hopefully zlib won't break when
that change is reverted :) Started my stress test again..

If you're using Ubuntu's dovecot-postfix package, it's actually
using /etc/dovecot/dovecot-postfix.conf, not dovecot.conf.

[Dovecot] Cannot create auth-master file

[Greg Frith]

Hi all,

I'm trying to get postfix and dovecot working nicely together to process and 
store mail for both local (system) on one domain and virtual users and a few 
different domains.

I've got postfix up and running quite nicely, but am having a few problems with 
Dovecot.  Every time postfix tried to delivery a message to a virtual user 
using dovecot I get an error like the following in /var/log/mail.log:

Mar  8 21:53:58 rhy postfix/pipe[6616]: 89C94846E: to=, 
orig_to=, relay=dovecot, delay=8795, 
delays=8794/0.01/0/0.61, dsn=4.3.0, status=deferred (temporary failure)

At the same instant, in my dovecot log I'll get this error:

deliver(gr...@gregsfamily.com): 2010-03-08 21:53:58 Error: Can't connect to 
auth server at /var/run/dovecot/auth-master: Connection refused

So, I'm guessing that this is a permissions issue (somewhere) and that the 
dovecot process is not able to create the file /var/run/dovecot/auth-master.  
The permissions on this folder are as follows:

gr...@rhy:/etc/dovecot$ ls -al /var/run/dovecot/
total 0
drwxr-xr-x  3 root  root100 2010-03-08 21:44 .
drwxr-xr-x 15 root  root660 2010-03-08 22:00 ..

drwxr-x---  2 root  dovecot  60 2010-03-08 21:44 login

I've searched around for hours, found several threads describing similar 
issues, but no solutions that have worked for me.  If anyone is able to give me 
any pointers or suggestions I would be most grateful.  

My dovecot configuration is:

gr...@rhy:/etc/dovecot$ sudo dovecot -n

http://dovecot.org/releases/1.2/dovecot-1.2.11.tar.gz.sig

mbox users really should upgrade, because by sending a message with a
huge header you could basically cause a DoS (this problem exists only
with v1.2.x, not with v1.0 or v1.1).

- mbox: Message header reading was unnecessarily slow. Fetching a
  huge header could have resulted in Dovecot eating a lot of CPU.
  Also searching messages was much slower than necessary.
- mbox, dbox, cydir: Mail root directory was created with 0770
  permissions, instead of 0700.
- maildir: Reading uidlist could have ended up in an infinite loop.
- IMAP IDLE: v1.2.7+ caused extra load by checking changes every
  0.5 seconds after a change had occurred in mailbox

If your 500 users are mostly email only then you will probably enjoy

This is how you can use mysql with dovecot. The emails will still be

Why do you think it would be worth it for any amount of users?
Performance would definitely become worse. The only good reason I can
think of would be if you wanted easy SQL access to all the mails for
data mining/statistics/whatever purposes.

You're confusing 'mailboxes' with user mail 'settings' and/or user
management.

Dovecot does not currently support storing users mail in any sql
database, although 2.0 is supposedly going to make it easier to
implement this with a plugin for anyone wants to write the code.

What you are reading about re: dovecot+mysql is simply using MySQL as
the backend for your user info. It can be as simple as username and
password, or you can add quota management, and even more (custom user
storage locations, etc) with extra_fields:

http://wiki.dovecot.org/UserDatabase/ExtraFields

Dovecot is extremely flexible with respect to configuration management.

Is it even worth it with less than 500 users? I mean I don't have any

Dovecot supports looking up user information from MySQL, but not
actually storing mails there. If you really wanted to store mails on
MySQL, you'd have to use dbmail instead of Dovecot.

[Dovecot] Using MySQL For Mailboxes?

[Carlos Mennens]

I have always seen some people indicate they use MySQL for mailboxes
in Postfix and I wondered how difficult something like this would be?
I have 300 users on my company Postfix server right now. I am just
using Postfix, Dovecot (IMAP4 only), & Roundcube (Webmail). I have
MySQL loaded on the machine that runs Postfix but only to manage the
database for Roundcube. Do you think that 300+ users is recommended
for a MySQL database for mailboxes?

Secondly, how difficult is it to configure this? Right now everyone
user has a home directory and a mailbox in their private home folder.
Is it hard to configure Postfix & Dovecot to use MySQL mailboxes? Just
looking for some suggestions since I couldn't find a log of info via
Google.

*PS* I was told that Dovecot doesn't support MySQL mailboxes. I think
it does. Am I wrong?

Oh, cool, so Dovecot does calculate the quota, if there is none in the 
database:


1) delete the quota of user $M
2) call

echo "x GETQUOTAROOT Inbox" | \
USER=$M /usr/sbin/dovecot --exec-mail imap

should do it.

Maybe, one needs to add

Hmm, I would expect a quota recalculation, too, if there is no current 
quota at all.


In the parents of the mail, there is the outline:

1. remove the quota in the DB,
2. make same changes.

With "| dovecot --exec-mail imap" you can do changes or request the 
current quota easily.


However, you probably need to set some environment variables or su to the 
user for "dovecot" running as the correct system user and mail user.

[Dovecot] force to recalculate quotadict

[Andre Hübner]

Hello,

i use working quotasystem with sql-quotadict.
The values stored in db are used to realize also a quotasystem in postfix to 
reject mails if they are bigger then remaining quota.
if dataset in quotadict is missing for some reasons, postfix can't calculate 
quota and mail gets delivered even if user is already over quota.
I am looking for a way to force dovecot/lda to recalculate users 
bytes/messages with command xy and not to wait for incomming mail.


Currently i use:
deliver -d $user -n -m folderwithunspeakablenamesonobodyusesthis
and send a small message which gets lost but starts the calculation.
This works but seems not to be the finest way.
Is there a better way or my current procedure acceptable?

Thanks,
Andre
