I did this before switching to antispam. I use antispam with spool2dir now, that central directory has a inotify watcher that trains the messages instantly. This is a great idea. In my case I think I will get away with a five minute cron job since the pickup latency should be manageable to the users and there is less to install. But I like in principle the idea of an immediate, fs-driven trigger, which would probably use fewer CPU cycles in the aggregate. [...]all my users moved messages into spam/yes, but copied them into spam/no Unfortunately I can't rely on users getting this right, much less understanding the difference between copy and move semantics.

[Dovecot] Issue with postfix not handing over e-mails to dovecot
Hello! I have installed postfix with dovecot and postgresql. I have set up SASL authentication for postfix and dovecot and been able to test them successfully. I am able to send sasl authenticated emails through smtpd on postfix using a mail client like Thunderbird. However, now I am unable to receive any e-mails. When I respond to the emails, I get a not delivered failure from postfix. I cannot figure out why postfix is not handing over the e-mails to dovecot. So here are some links to follow: posftconf output: https://gist.github.com/anonymous/7318863 doveconf output: https://gist.github.com/anonymous/7318896 tail -f /var/log/mail.* output (when receiving mail): https://gist.github.com/anonymous/7318945 Any help to solve this would be highly appreciated.

[Dovecot] Message parser loops on certain messages (e.g. with a trailing CR character)
Hi,
dovecot's message parser enters an endless loop when fed with certain
multipart messages with stray CR characters.
parse_next_body_to_boundary() assumes the '\r' might be the beginning
of a boundary line, reducing the block size by one:
src/lib-mail/message-parser.c:
404 /* no linefeeds in this block. we can just skip it. */
405 ret = 0;
406 if (block_r-data[block_r-size-1] == '\r') {
407 /* this may be the beginning of the
\r\n--boundary */
408 block_r-size--;
409 }
For a block size of 1 (e.g. the trailing '\r' character), dovecot ends
up processing zero-sized blocks, calling message_parser_read_more()
without skipping the input stream:

You will find a sample message attached to this mail.
I have added a check to see if the parser is past the EOF (and omit
reducing the block size then) as a band-aid fix, but this might call
for a more elegant solution.

[Dovecot] Config problem: want SSL + local roundcube
Hi,
Have used dovecot for many years, happy that it worked well without me
needing to do anything much! But since the upgrade from v1 to v2.1.7-7
I've come across some config probs.
I want IMAP and to force TLS for all internet connections. However, I
run RoundCube on the same server (over https) and this needs access too,
but this doesn't need to be TLS because it's local anyway.
The auto-config update script made some changes, it added the following
to force SSL.
service imap-login {
inet_listener imap {
port = 0
}
}
ssl = required
But this seems to forbid the local roundcube service from logging in.
Can anyone help me with my config? I had a stab, adding the following,
but it didn't work. Was a complete guess anyway!
remote 127.0.0.1 {
ssl = no
service imap-login {
inet_listener imap {
port = 143
}
}
}
Here's my full config:
# 2.1.7: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-5-amd64 x86_64 Debian 7.2 ext3
auth_default_realm = artfulrobot.com
log_timestamp = %Y-%m-%d %H:%M:%S
mail_location = maildir:/home/virtual/%d/%n
mail_privileged_group = mail
passdb {
args = username_format=%n /etc/exim4/virtual_domains/%d/passwords
driver = passwd-file
}
protocols = imap
service auth {
unix_listener auth-client {
group = Debian-exim
mode = 0660
}
user = root
}
service imap-login {
inet_listener imap {
port = 0
}
}
ssl = required
ssl_cert = /etc/ssl/certs/mail.artfulrobot.com-with-chain.crt
ssl_key = /etc/ssl/private/mail.artfulrobot.com.key

have you tried that it matters or do you only guess?
http://trac.roundcube.net/ticket/1485771
and I could not get RC to connect on port 993 for some reason
http://trac.roundcube.net/wiki/Howto_Config
'default_host'
By default the login screen provides a text box where you need to enter the
IMAP host which you want to connect to.
This box can be hidden by setting one fixed IMAP host address:
$rcmail_config['default_host'] = 'localhost';
To use SSL/TLS connection, enter the hostname with prefix ssl:// or tls://
And if you want a drop-down list like it's explained in the comments you need
something like this:
$rcmail_config['default_host'] = array('mail.example.com',
'webmail.example.com', 'ssl://mail.example.com:993');

Re: [Dovecot] Config problem: want SSL + local roundcube
Ok, thanks for your time, let's end this thread. Seems it's probably more a RC thing than a Dovecot thing. Still can't get it to work (yes I'd already RTFM'ed and tried all the various RC config options) but happy to ask over at RC instead. Thanks. Rich

Re: [Dovecot] Message parser loops on certain messages (e.g. with a trailing CR character)

I think I did the same fix. Also I don’t think it’s possible to normally use this as a DoS attack against users, because with mail_save_crlf=no (default) the CRs are stripped. And with mail_save_crlf=yes I’m not sure if such message can even pass through SMTP servers.

Unless these are exceeding long, you probably should inline the contents
to save people from having to jump around to get the information to
help you. It will also properly archive the context to the solution.
From your logs, it appears your mail system does not know what user is
mapped to some...@mydomain.com:
Nov 5 13:21:06 localhost postfix/local[11185]: 5716D8007B:
to=some...@mydomain.com, relay=local, delay=0.59, delays=0.57/0.01/0/0.01, dsn=5.1.1,
status=bounced (unknown user: someone)
I don't know whether this message is produced by postfix or by dovecot,
but one thing I did notice is that your postfix configuration
mailbox_command = /usr/lib/dovecot/deliver -c
/etc/dovecot/conf.d/01-mail-stack-delivery.conf -m ${EXTENSION}
has upper-case EXTENSION, whereas the Dovecot wiki uses lower case:
http://wiki2.dovecot.org/LDA/Postfix
If that's not it, maybe it's your SQL. You can also ask dovecot
to look up user somebody and debug your way from there:
doveadm user somebody

[Dovecot] Postfix delivers mails to maildir and not to dovecot LDA for a virtual user
Hi
I have been able to setup postfix and dovecot using postgres as the backend
store with virtual user maps on Ubuntu 12.04 LTS Server.
I have been following instructions from here:
http://wiki2.dovecot.org/HowTo/DovecotPostgresql
I haven't setup postfix to use saslauthd and PAM, instead I am using
dovecot for SASL authentication. Rest of the table structures and query
files are the same as from the wiki.
SASL authentication works correctly for SMTP POP IMAP.
I am able to send emails from a mail client such as Thunderbird with SASL
authentication.
However I am not able to receive emails for virtual users. I cannot figure
out why. System users are getting their emails in the mail box correctly.
Postfix fires the mailbox_command to hand over the mail to dovecot.
This is how my *mail.log* looks when I send emails from an external domain:
Nov 6 06:48:21 localhost postfix/smtpd[20053]: E075280C52: client=

mail-ee0-f41.google.com[74.125.83.41]
Postfix seems to deliver the mail to maildir instead of the home directory
of the virtual user. Incase of the system user, the logs indicate that the
mailbox_command was fired and I do get to see the mail in the inbox.

[Dovecot] get_disconnect_reason() gets called with NULL ctx-litinput
Hi,
I have found get_disconnect_reason() to be called with NULL
ctx-litinput at times, making dovecot crash when accessing v_offset:
src/imap/cmd-append.c:
83 switch (i_stream_read(client-input)) {
84 case -1:
85 /* disconnected */
86 reason = get_disconnect_reason(ctx,
ctx-litinput-v_offset);
87 cmd_append_finish(cmd-context);
88 /* Reset command so that client_destroy()
doesn't try to call
89 cmd_append_continue_message() anymore. */
Best regards,
Tomasz Potęga
