Frank Bonnet articulated:
if you install from FreeBSD ports you need to enable

If you don't install Dovecot via the FreeBSD ports system, you are just
asking for problems. As previously stated, do run "make config" and
perhaps "make config-recursive" prior to actually attempting to build
the port.
I did, MySQL is ticked when i build dovecot2 from
/usr/ports/mail/dovecot2/
If you do dovecot --build-options, does it list mysql?
root@mail:~# dovecot --build-options
Build options: ioloop=kqueue notify=kqueue ipv6 openssl
io_block_size=8192
Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw
SQL drivers: mysql
Passdb: checkpassword pam passwd passwd-file sql
Userdb: checkpassword nss passwd prefetch passwd-file sql
At first i have noticed that i dont have mysql when i did
--build-options, so i tried to deinstall and reinstall dovecot2 port and
now i have this also:
hostname# dovecot --build-options

Just a follow-up to report that I finally have the Antispam plug-in (the
Johannes version) -- with the mailtrain/pipe back-end -- working as
expected in both of the following environments:
- Ubuntu 10.04 with Dovecot 1.2.9
- Ubuntu 12.04 with Dovecot 2.0.19
In addition to the points that I mentioned in my previous note, a
crucial step in the debugging process was to modify the
"sa-learn-pipe.sh" script to produce more verbose output. Unlike
Antispam 2, Antispam 1 lacks a verbose debugging mode, so when the
plug-in does not work as expected, tracking-down the root cause can be
much more difficult.
Here's the shell script from http://wiki2.dovecot.org/Plugins/Antispam ,
with my modifications:
http://pastebin.com/igTXCYQF
After making these modifications to the shell script, I was able to
determine the cause of the failure in Dovecot 1.2.9. In fact, I was
incorrect earlier when I stated that version 2 was working; the same
problem applied there, too.
The "vmail" user, as whom the script is executed, lacks the permissions
required to change the Bayes token database (this is a "good thing").
An excerpt from the custom log file:
29722-start (--spam)
Calling (as user vmail) '/usr/bin/sa-learn --spam
/tmp/sendmail-msg-29722.txt'
bayes: expire_old_tokens: locker: safe_lock: cannot create tmp lockfile

for more information at /usr/bin/sa-learn line 493.
Learned tokens from 0 message(s) (1 message(s) examined)

The only means by which I was able to work around this issue -- without
changing filesystem permissions, users, groups, or otherwise
compromising system security -- was to migrate from the standard
flat-file Bayes database format to MySQL. (The guide at

Re: [Dovecot] Wrong quota calculation
Hi Timo, I've finally solved the issue. As usual, thinking out of the box helped :) In fact, it was conf related but not where it was expected. There was an autocreate = Inbox & autosubscribe = Inbox in 90-plugin.conf Having this configuration seems to double count the Inbox quota during quota recalc (but not during normal IMAP operations like moving or receiving a message). Might be some kind of bug somewhere in recalc. The strange thing is that another more simple dovecot system we have (no nfs, all imap/smtp/filtering operations done on the server) also has this plugin conf but doesn't count quota twice. Anyway, after running a small script to recalc all the quota, everything is now fine.

I'm not sure that what we see in Thunderbird is related to the problem but who knows. Any help is of course welcome as we're out of ideas :) Create a test server. Make your Dovecot config minimal. Test with another quota backend. Test with local filesystem. See what change breaks the quota calculation. It is somehow related to your current config, since it's not broken for everybody.

Thanks for your reply, Bradley.
That seems to be the implication here:
http://manpages.ubuntu.com/manpages/precise/man7/dovecot-antispam.7.html
Johannes is listed as an author, the package name is
dovecot-antispam_2.0+20120225, and the manpage is nearly identical to
that of version 1 at
http://manpages.ubuntu.com/manpages/lucid/man7/dovecot-antispam.7.html .

This documentation seems to apply to the Dovecot 2 version; the
antispam_backend directive doesn't seem to exist in version 1, at least
according to the official Ubuntu package documentation (cited above). In
fact, this appears to be the exact document that is used for the Ubuntu
package for Dovecot 2 (also cited above).

Is there a Johannes version 2?
I understood that Johannes dropped support at dovecot 2.x and that is why

Description: S/MIME cryptographic signature
[Dovecot] Sieve as mail client?
A slightly off topic question, but maybe someone here has seen something like this: I want a program that operates entirely on the client side of an IMAP server, and implements the sieve filtering language by doing the necessary client side operations to move mail on the IMAP server, expunge mail, etc. It would also act as a proxy between my real mail client and the IMAP server so I'd never see any mail that hasn't been filtered first. The benefits are obvious: I could finally get sieve filtering on my stupid corporate exchange mail server :-).
[Dovecot] doveadm with multiple commands
This has been in my TODO for a while and today I implemented it (but didn't dare to test it yet :) So the problem has been that you want to run for example: doveadm expunge -A mailbox Trash savedbefore 7d doveadm purge -A This is annoying because it scans through the users' mailboxes twice, wasting disk IO and CPU. So how to make it do the scan only once? The syntax I thought of today would be: doveadm multi [-A | -u wildcards] [ [...]] So the first two commands could be for example: doveadm multi -A : expunge mailbox Trash savedbefore 7d : purge The ':' character is the separator. Any other string could be used as well, for example "?SEP?" or whatever. Thoughts? Any better name for the command than "multi"?

You nailed it, Ben. Thanks!
I downloaded/installed the dovecot-dev package from the same maintainer
and was able to build Antispam without issue.
The hang-up now seems to be with my configuration.
I'm seeing the following error in my email client whenever I attempt to
move an email message from, say, Inbox to Junk folder:
[SERVERBUG] BUG Unknown internal error.
Nothing at all appears in syslog when this happens.
I followed the instructions at http://wiki2.dovecot.org/Plugins/Antispam
, to the letter, I believe.
The relevant portions of my configuration are as follows:
-
protocol imap {
mail_plugins = quota imap_quota antispam
}
plugin {
quota = dict:user::file:/var/vmail/%d/%n/.quotausage
sieve = /var/vmail/%d/%n/.sieve
antispam_backend = MAILTRAIN
antispam_mail_sendmail = /usr/bin/sa-learn-pipe.sh
antispam_mail_spam = --spam
antispam_mail_notspam = --ham
antispam_spam_pattern_ignorecase = spam;junk
}
-
The permissions and execute bit are set in accordance with other
executables in the same directory:
# ls -lah /usr/bin/ | grep -i "sa-learn-pipe.sh"
-rwxr-xr-x 1 root root 297 Sep 5 11:17 sa-learn-pipe.sh
I would provide more log content, but the debug options seem to be gone
in the forked, >= 2.0 version of this plug-in.
Any ideas are very much appreciated.

Re: [Dovecot] Prevent Download messages from server
do you mean to leave a copy of the email on the server so it can be read in multiple email clients? IMAP can do this and i think modern POP3 can. look for an account config option in your mail client to "leave mail on server". i think there is a setting in dovecot to prevent expunging of email but it has been years since i was researching this. -david On 09/20/2012 02:21 AM, Selcuk Yazar wrote: Hi, can we prevent download messages from server user by user ? sme common used mail's message must be remain at the server, but sometimes we download them ? thanks in advance

I downloaded/installed the dovecot-dev package from the same maintainer
and was able to build Antispam without issue.
The hang-up now seems to be with my configuration.
I'm seeing the following error in my email client whenever I attempt to
move an email message from, say, Inbox to Junk folder:
[SERVERBUG] BUG Unknown internal error.
Nothing at all appears in syslog when this happens.
I followed the instructions at http://wiki2.dovecot.org/Plugins/Antispam
, to the letter, I believe.
The relevant portions of my configuration are as follows:
-
protocol imap {
mail_plugins = quota imap_quota antispam
}
plugin {
quota = dict:user::file:/var/vmail/%d/%n/.quotausage
sieve = /var/vmail/%d/%n/.sieve
antispam_backend = MAILTRAIN
antispam_mail_sendmail = /usr/bin/sa-learn-pipe.sh
antispam_mail_spam = --spam
antispam_mail_notspam = --ham
antispam_spam_pattern_ignorecase = spam;junk
}
-
The permissions and execute bit are set in accordance with other
executables in the same directory:
# ls -lah /usr/bin/ | grep -i "sa-learn-pipe.sh"
-rwxr-xr-x 1 root root 297 Sep 5 11:17 sa-learn-pipe.sh
I would provide more log content, but the debug options seem to be gone
in the forked, >= 2.0 version of this plug-in.
Any ideas are very much appreciated.
Thanks,

Given that nobody shared any insight here, I decided to stand-up a
completely new VM with Ubuntu 12.04 LTS and see if the same error occurs.
While the error is different this time around, I am still unable to get
any variant of the dovecot-antispam plug-in working.
When I attempt to use the current packages from Ubuntu 12.04.1 LTS, and
I use the above configuration, my syslog fills-up with the following:
dovecot: imap-login: Login: user=, method=PLAIN,
rip=10.0.1.57, lip=10.0.1.8, mpid=2879, TLS
dovecot: master: Error: service(imap): child 2879 returned error 3
Surprisingly, I can find only two other mentions of "error 3" anywhere
on the Internet. Those mentions were from another user to this mailing list:
http://www.dovecot.org/list/dovecot/2012-August/067787.html
http://www.dovecot.org/list/dovecot/2012-August/067814.html
The lack of "error 3" ubiquity leads me to believe that I must be doing
something stupid.
There's no question that this behavior is related to the
antispam-plugin, because when I commented-out the relevant lines in
Dovecot's configuration file, the error does not occur.
I have followed the instructions at
http://wiki2.dovecot.org/Plugins/Antispam to the letter, and this is the
result.
The only instance in which I diverged from the Wiki article is that I
used the Ubuntu-provided dovecot-antispam package (instead of compiling
the plug-in from source).
I am trying to use the "mailtrain" back-end, per the above-cited Wiki
article, to call SpamAssassin's "sa-learn" utility for real-time learning.
I am not using the SpamAssassin daemon (spamd).
I'm about to throw in the towel on this plug-in, so any help would be
greatly appreciated.
Thank you,
-Ben
I've never used this plugin but let offer up my home brewed script that
I call from crontab:
# Process and delete .Spam and .Ham Maildirs
11 */4 * * */usr/local/sbin/maildir.sa-learn
and /usr/local/sbin/maildir.sa-learn:
#!/bin/bash
MAILDIR=Maildir
LS=/bin/ls
RM=/bin/rm
SU=/bin/su
FIND=/bin/find
SALEARN=/usr/bin/sa-learn
for i in `$LS /home`; do
prefs="/home/$i/.spamassassin/user_prefs"
# [ ! ."$i" == ".bill" ] && continue
echo $i
spamdir="/home/$i/$MAILDIR/.SystemFolders.Spam"
[ ! -d "$spamdir" ] && continue
$SU -c "$SALEARN --prefspath=$prefs --spam $spamdir/new" $i
$FIND "$spamdir/new" -type f -delete
$SU -c "$SALEARN --prefspath=$prefs --spam $spamdir/cur" $i
$FIND "$spamdir/cur" -type f -delete
hamdir="/home/$i/$MAILDIR/.SystemFolders.Ham"
[ ! -d "$hamdir" ] && continue
$SU -c "$SALEARN --prefspath=$prefs --ham $hamdir/new" $i
$FIND "$hamdir/new" -type f -delete
$SU -c "$SALEARN --prefspath=$prefs --ham $hamdir/cur" $i
$FIND "$hamdir/cur" -type f -delete
done
With my setup each user has their own spamassassin user_prefs and bayes
tokens.

Re: [Dovecot] Prevent Download messages from server
Am 20.09.2012 09:28, schrieb Selcuk Yazar: Alessio and Peter thank you again. maybe it can be future request. :) We are trying to tell you that it is impossible to write a mail _client_ that does not download (i.e. transfer) the mail that it shows to the user. This is why it makes no sense to prevent the download on the server side, and so there will never be such a function. Preventing the download (the transfer) of the mail fro mthe server to the client just means that the user *cannot read it*. Another question is whether there are mail _clients_ which do not offer a possibility to *save* the read mail (which has already been "downloaded" for reading it). But that question is not really related to the dovecot mail server. If you want to get users to read mails, but not download them, I would suggest you deny the direct access to the mail server and use a browser-based application that shows the entire mail to the user, maybe as a graphical representation. Or you use some sort of terminal software that connects to a host where the mail _clients_ itself are installed, just letting the user view the data but nor copy it, e.g. the VNC protocol. Hope this helps, Jakob Curdes

As in ALL Internet protocols (IMAP being no exception), letting the client read data on the server requires it to download the data. Preventing download will prevent reading the mail. Period. So if you're fine with that and just want to learn how to do it, then just disable the account in the user database. /Peter

I suppose you understand what you mean by changing folder permissions! If you make them read-only (no write) for the users group, as that is what you could be thinking, you'll probably also affect the ability of the MTA to write to them (deliver mail).
