Topic: Sieve Problem

Hi all,

Our customer reports, the roundcube filtering function reports error. But after restart the service, it resume normal.

But during we restart the service, we found many process cannot stop. After we manually kill the service, the pysieved service can start up. But according to this issue, will it related to the below configure? Or it should have another way to solve this issue? Please advice. Thanks.

Re: Sieve Problem

After I follow the xinetd way to create the sieve service. It doesn't work. When I telnet to the localhost 2000 port, it returns below error messages.

Trying 127.0.0.1...
Connected to localhost.

Re: Sieve Problem

There's a section "[Dovecot]" in /etc/pysieved.ini, and you should set "uid" and "gid" in it:

[Dovecot]
...
uid = 500
gid = 500

Here, uid and gid are uid/gid of vmail user. You can get it with commands:

# id -u vmail
# id -g vmail

Re: Sieve Problem

I have checked the configure file and uid/gid. It configured correctly but still getting the same problem.

# Community: http://www.iredmail.org/community.html
#

[main]
# Authentication back-end to use
auth = Dovecot

# User DB back-end to use
userdb = Virtual

# Storage back-end to use
storage = Dovecot

# Bind to what address? (Ignored with --stdin)
#bindaddr = 127.0.0.1

# Listen on what port? (Ignored with --stdin)
port = 2000

# Write a pidfile here
pidfile = /var/run/pysieved/pysieved.pid

[Virtual]
# Append username to this for home directories
base = /var/vmail/sieve

# What UID and GID should own all files? -1 to not bother
uid = 503
gid = 503

# Switch user@host.name to host.name/user?
hostdirs = True

[Dovecot]
# How do we identify ourself to Dovecot? Default is 'pysieved'.
service = managesieve

# Path to Dovecot's auth socket (do not set unless you're using
# Dovecot auth)
mux = /var/spool/postfix/dovecot-auth

# Path to Dovecot's master socket (if using Dovecot userdb lookup)
master = /var/run/dovecot/auth-master

# Path to sievec
sievec = /usr/libexec/dovecot/sievec

# Where in user directory to store scripts.
scripts = .

# Filename used for the active SIEVE filter (see README.Dovecot)
active = dovecot.sieve

# What user/group owns the mail storage (-1 to never setuid/setgid)
uid = 503
gid = 503

The id of vmail group and user are correct (503)

Re: Sieve Problem

I tested on local VM, and found the root cause.

What's the value of "user" and "group" in xinetd config file? is it "vmail"? If so, you should change file owner of /etc/pysieved.ini to vmail. This fixes your issue.

Re: Sieve Problem

service sieve
{
disable = no
socket_type = stream
wait = no
user = vmail
group = vmail
server = /usr/sbin/pysieved
server_args = --inetd --config /etc/pysieved.ini
umask = 002
log_on_failure += USERID
}

Re: Sieve Problem

Did you change file permission of /etc/pysieved.ini? does it work?

Re: Sieve Problem

yes, but once I stopped the pysieved, and try to start xinetd. the webmail seems stopped. So I need to test it tonite to prevent downtime. I will update you after test

(previously, /etc/pysieved.ini's permission is mail:mail)

Re: Sieve Problem

The xinetd seems ok when using telnet to local port 2000. But the webmail and the iredadmin doesn't work after pysieved stopped.

Re: Sieve Problem

What do you mean "webmail and iredadmin don't work after pysieved stopped"?

iRedAdmin doesn't require pysieved, and webmail just try to use port 2000, if you have pysieved running as inetd service, it should be ok too.

Re: Sieve Problem

Yes, suppose it is separated. But on my system, once pysieved stopped, all web service not work. But once I start the pysieved again, all webmail and iredadmin page resumed.

Re: Sieve Problem

Does xinetd start other services?

Pysieved just listen on port 2000 (and bind to 127.0.0.1 by default), so i don't think stopping pysieved will break other services.

Re: Sieve Problem

The problem is fixed after change of permission, the xinetd can start without affecting the web service. But we found, after a period to run the xinetd instead of pysieve, it will occupied mysql connections and results webmail and admin page malfunction. (It will return database error or in admin page, too many connection.)

Re: Sieve Problem

Are you sure that mysql issue is caused my xinetd/pysieved?
Which component(s) will need many mysql connection/queries?

Re: Sieve Problem

Yes, I fixed the problem via stop xinetd. Then I start pysieve manually.

After I move to xinetd, I experienced mysql connection busy. To prevent this happen, need to change the my.cnf the max connection then the problem can be fully fixed (so far no users complaint these days)
