HELP me: Email not receiveing after setting up filtering spam in rainLoop

Support and Discussion General Discussion

Hi,
I need urgent help with sieve

I setted up this carefully following all steps:

at the end of process: the fliters did not worked in individual accounts nor receiving emails in any ofthe server accounts.
I can send with no issues but i cannot received

The only difference Ihad with the settings was the first line:

Append “sieve” after ‘lmtp’ in protocols on the first line:

protocols = imap pop3 lmtp sieve

the difference was that i did not have lmtp on that line .

I have gone back correcting the settings to protocols = imap pop3 that is what I had at the beginning, ut still not working

I have centos 7

2

this also i did to enble lmpt

edit /etc/dovecot/conf.d/20-lmtp.conf file to configure dovecot to enable the sieve plugin.

protocol lmtp {

Space separated list of plugins to load (default is global mail_plugins).

mail_plugins = $mail_plugins sieve
}

do not know what has gone wrong as I followed instructions as they are

3

make sure hostname is set to your email server hostname in the dovecot.conf file: postmaster_address = postmaster@mydomain.com
hostname = mail.mydomain.com

4

Also make sure that port 4190 is opened in your firewall

this one not opened, how shall I do it?

[root@fra ~]# netstat -tunlp | grep :4190
tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 16312/dovecot
tcp6 0 0 :::4190 :::* LISTEN 16312/dovecot
udp 0 0 0.0.0.0:41901 0.0.0.0:* 2238/openlitespeed

Thanks @NiiYankee

gone through all again opened port 4190, hostname and postmaster changed to mine

and firewall opened,
21 sieve tcp 0.0.0.0/0 4190

still no emails through

8

There is a bud in the sieve script. This is the error I got also: sieve: Failed to access user’s personal storage (temporary failure)

9

*bug

10

how can I revert? I have some very angry clients

Remove sieve and its configurations and your emails should start coming in again. Wait until there is a fix then try it again. After all, sieve with rainloop is beta.

Follow these steps:

  1. sudo yum remove dovecot-pigeonhole -y

  2. nano /etc/dovecot/dovecot.conf and remove the following: lmtp sieve in the first line then remove this: service auth {
    unix_listener auth-client {
    group = postfix
    mode = 0660
    user = postfix
    }

    unix_listener auth-master {
    group = vmail
    mode = 0660
    user = vmail
    }

    user = root
    }

service managesieve-login {
inet_listener sieve {
port = 4190
}
}
service managesieve {
}
protocol sieve {
managesieve_max_line_length = 65536
managesieve_implementation_string = dovecot
log_path = /var/log/dovecot-sieve-errors.log
info_log_path = /var/log/dovecot-sieve.log
}
plugin {
sieve = ~/dovecot.sieve
sieve_global_path = /etc/dovecot/sieve/default.sieve
sieve_dir = ~/sieve
sieve_global_dir = /etc/dovecot/sieve/global/
}
lda_mailbox_autocreate = yes
lda_mailbox_autosubscribe = yes
protocol lda {
mail_plugins = $mail_plugins autocreate sieve quota
postmaster_address = postmaster@mydomain.com
hostname = mail.mydomain.com
auth_socket_path = /var/run/dovecot/auth-master
log_path = /var/log/dovecot-lda-errors.log
info_log_path = /var/log/dovecot-lda.log
}
protocol lmtp {
mail_plugins = $mail_plugins autocreate sieve quota
log_path = /var/log/dovecot-lmtp-errors.log
info_log_path = /var/log/dovecot-lmtp.log
}

  1. Save the dovecot.conf file

  2. Remove the folder at /etc/dovecot/sieve/global

  3. systemctl restart dovecot

  4. systemctl restart postfix

Your emails should start rolling in again

12

Thanks a LOT @NiiYankee you are a star!!
All coming through now

I found the solution for the sieve error on the forum: in the dovecot.conf file look for:

plugin {
sieve = ~/dovecot.sieve
sieve_global_path = /etc/dovecot/sieve/default.sieve
sieve_dir = ~/sieve
sieve_global_dir = /etc/dovecot/sieve/global/
}

and replace with this:

plugin {
sieve = /home/vmail/%d/%n/dovecot.sieve
sieve_global_path = /etc/dovecot/sieve/default.sieve
sieve_dir = /home/vmail/%d/%n/sieve
sieve_global_dir = /etc/dovecot/sieve/global/
}

14

Won’t risk I followed the instructions exactly as they appear and did not work. So until they are correct prefer spam. Even if with the set to delete (1) in server does not work either

15

Usually, this happens when the Spamassassin line in /etc/postfix/master.cf is wrong. Seen this on some installations.

If this is an existing installation then the below is how i setup that for all clients sieve to work by default to spam folder of Rainloop “INBOX.Junk E-mail”.

Install spamasassin via cyberpanel

backup configs:
cp /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf-bak_$(date ‘+%Y-%m-%d_%H:%M:%S’);
cp /etc/postfix/master.cf /etc/postfix/master.cf-bak_$(date ‘+%Y-%m-%d_%H:%M:%S’);
cp /etc/postfix/main.cf /etc/postfix/main.cf-bak_$(date ‘+%Y-%m-%d_%H:%M:%S’);

cp /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf-bak-sieve
cp /etc/postfix/master.cf /etc/postfix/master.cf-bak-sieve
cp /etc/postfix/main.cf /etc/postfix/main.cf-bak-sieve

Please NOTE:
TO reverse these modifications the below commands can be used.
cp /etc/dovecot/dovecot.conf-bak /etc/dovecot/dovecot.conf
cp /etc/postfix/master.cf-bak /etc/postfix/master.cf
cp /etc/postfix/main.cf-bak /etc/postfix/main.cf

Install required packages

spamassassin unix - n n - - pipe flags=DROhu user=vmail:vmail argv=/usr/bin/spamc -f -e /usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}

Optional things that might be needed.

If you get this error:
spamc[7957]: connect to spamd on ::1 failed, retrying (#1 of 3): Connection refused

Disable IPv6:
Append below lines in /etc/sysctl.conf:
nano /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

To make the settings affective, execute :
sysctl -p

Add missing spamd user:
groupadd spamd
useradd -g spamd -s /bin/false -d /var/log/spamassassin spamd
chown spamd:spamd /var/log/spamassassin
service spamassassin restart

Create this file with the below value to ensure spamd listening on localhost
[root@srv ~]# cat /etc/mail/spamassassin/spamc.conf
-d 127.0.0.1
[root@srv ~]#

/etc/sysconfig/spamassassin

With existing data use this dovecot conf

New installs without existing email data.

For new installations, without any email data, I typically use this version. This uses a universal namespace for the names so it works better with Dovecot 2.3.x and email clients similar to how the cPanel and other ones do out of the box

Install spamasassin via cyberpanel for new installations without existing email data and files all spam into “INBOX.Junk”

cp /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf-bak_$(date ‘+%Y-%m-%d_%H:%M:%S’);

I got Sieve up and working on Cyberpanel 2.1.1 Centos 7
What I noticed was that Cyberpanel’s dovecot version was 2.3 but the dovecot-pigeonhole available was not for that version.
I tried downgrading but that did not work since the configurations of the newer dovecot was different and caused “Authentication Failed” when logging in. So I had to go back up to version 2.3

These are my steps:
N.B. Step one will update dovecot to the latest version. Please make sure to keep track of your current version in order to rollback if configuration files clash.
What you are aiming to do is to get dovecot-pigeonhole the same version as your current setup.

First setup dovecot repository following this link:

Secondly, follow instructions in this link.
