[Dovecot] passwd userbase and multiple email adresses

[spamvoll]

Hi..

i want to use a passwd file for user configuration.. but how can i add
emailadresses(multiple) to those users ?
postfix -> dovecot

passwd looks like:
test:{PLAIN}pass

there must be some kind of userdb right ? But i cant find any infos

the answer is: when tuning is needed, you will know it: you will have
concrete problems.

if you observe no problem, tune your week-end instead. as the saying
goes: "premature optimisation is the root of all evil".

Re: [Dovecot] NoSQL Storage Backend

[Marc Perkel]

The way I do MySQL backups is that I do a slave on another server. When 
I need to backup I stop the slave - back it up - then start it again.

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 :)

Yup.  Every time I run it against one of the mailboxes that reports an

Running against one of my mailboxes that is clean gives no error - but I 
don't see fts indexes being generated.  I have included fts and

not enough file descriptors ?

[Dovecot] Cannot subscribe to shared folders

[Lukas Haase]

Hi,

I am unable to subscribe to shared folders with Thunderbird although 
everything seems to be correct (dovecot 1.2).


What does not work? I click "Subscribe..." in Thunderbird. The shared 
mailboxes are listed, all with [ ] (no checkbox). Therefore I mark them 
[x], click "subscribe" and "OK". However, the folders do not appear in 
the folder tree. Furthermore, when I again click "Subscribe..." the 
folders do NOT have the mark [x] any more. This happens on different 
computers with *new* profiles.


My configuration is the following (maybe that is the problem?!):

namespace private {
   separator = .
   prefix =.
   inbox = no
   list = no
   hidden = yes
   location = maildir:~/Maildir-root
   subscriptions = yes
}

namespace private {
   separator = .
   prefix = INBOX.
   inbox = yes
   subscriptions = yes
}

namespace public {
   separator = .
   prefix = Shared.
   location = maildir:/var/mail/shared:INDEX=~/Maildir/shared:LAYOUT=fs
   subscriptions = no
}

The folder /var/mail/shared has appropriate permissions/form:
* Owner: $user:mailuser (all users are member of "mailuser")
* All files 0660, all folders 0770
* There exists a dovecot-shared in every folder
* There exists a dovecot-acl in each folder where each user has the 
permissions "lrwstie"


I switched on "mail_debug = yes" but no messages.

However, the file ~/Maildir-root/subscriptions contains the subscribed 
folders:


Shared.Group1
Shared.Group2
Shared.Group1/Test

Furthermore, I switched on rawlog. Everything seems to be OK as well:

.in-file:
2 subscribe "Shared.Group1"
3 lsub "" "INBOX.*"
5 lsub "" "Shared.*"
6 list "" "INBOX"

.out-file:
2 OK Subscribe completed.
[...]

I am pretty sure it already worked. But it stopped working. Does anybody 
have a hint what could be the problem?

Luke

[Dovecot] SIS generating 2 different hashes for the same mail and attachment

[Nick Rosier]

Hi,

I've been testing SIS over the weekend as it seems to be a nifty 
feature. I don't have that many users and mailboxes but still...

I only added the following line to my configuration:

mail_attachment_dir = /var/spool/vmail/attachments

As a test I sent a mail from GMail to 2 mailboxes (1 To and 1 CC). The 
attachment got saved to the attachment directory (on ZFS):


# find .

./04/78
./04/78/0478b28c2a4c235370bb3cef4bc0482bb6000dae-b8819638a60e574d5b530100bde47b1f-2088e7301f9e3c4dc97ebde47b1f-244

All m.* files are created by preallocating them into mdbox_rotate_size
size. The idea is to avoid fragmentation of the m.* files.

[Dovecot] FreeBSD tuning for a dovecot + postfix server ?

I've googled around  to tune a bit my mailhub ( AMD64 FreeBSD 8.1, 12 Gb 
RAM, 2 Tb raid5 disks , ~4000 mailboxes unix users )

All my clients use thunderbird as MUA ( IMAP, IMAPS ) to connect to the

no direct access to the machine.

Any of you guys has some pointer to give ?

[Dovecot] Sendmail and Dovecot deliver (dovecot-lda)

[Giles Coochey]

Hi,

I have a Centos 5 system with sendmail running as my MTA.

Normally I note from sendmail logs that mails get delivered using the 
'local' mailer.


I have therefore entered the following into my sendmail.mc file, from an 
earlier post on this list:


define(`LOCAL_MAILER_PATH',`/usr/libexec/dovecot/deliver')
define(`LOCAL_MAILER_FLAGS',`DFMPhfnu9')
define(`LOCAL_MAILER_ARGS',`deliver -d $u')

However, when sendmail tries to use deliver I just get this message:

Feb 13 15:37:23 gate sendmail[1399]: p1DEWtc2021995: 
to=, delay=00:04:28, xdelay=00:00:00, mailer=local, 
pri=121665, dsn=4.0.0, stat=Deferred: local mailer 
(/usr/libexec/dovecot/deliver) exited with EX_TEMPFAIL


I've tried to get better logging by putting the following in 15-lda.conf 
in /etc/dovecot/conf.d:


protocol lda {
  postmaster_address = postmas...@example.org
  auth_socket_path = /var/run/dovecot/auth-master
  mail_plugins = sieve
  mail_location = maildir:~/.maildir
  log_path = /var/log/dovecot-deliver.log
  info_log_path = /var/log/dovecot-deliver.log
}

I find nothing gets written to the log file, even if I make it a world 
writable file.


Does anyone have any ideas? What are the best steps to get more 
information troubleshooting?
