[TIP] How to setup Qmail on Kloxo-MR
« on: 2013-04-29, 20:06:45 »
This tips related to Qmail-toaster (mail server) on Kloxo-MR.

Warning: - update Kloxo to Kloxo-MR need running:
Code: [Select]
sh /script/convert-to-qmailtoaster

Prepare server:
1. Choose 1 of domains or subdomains as primary 'domain' (this domain must be access from public; example: 'mydomain.com')

2. Set server hostname as subdomain of primary 'domain' (example: 'subdom.mydomain.com') and add 'subdom' as 'A record' on dns setting

3. Add 'xxx.xxx.xxx.xxx subdom.mydomain.com subdom' on '/etc/host' (change xxx.xxx.xxx.xxx with primary ip)

4. Add/Change to 'HOSTNAME="subdom.mydomain.com"' in '/etc/sysconfig/network'

5. Reboot and then run 'hostname -f' and must be appear as 'subdom.mydomain.com'

Setup/Update qmail:
1. For update from Kloxo, need running 'sh /script/convert-to-qmailtoaster'
2. For to make sure, go to 'Mysql password reset' to change mysql root password
2. Running 'sh /script/fix-chownchmod; sh /script/fixmail-all'

Testing:
1. Run '/home/vpopmail/bin/vdominfo' and will be match with '/var/qmail/users/assign' content

2. If login to webmail failed, check the content of:
- '/var/qmail/supervise/imap4/run',
- '/var/qmail/supervise/imap4-ssl/run',
- '/var/qmail/supervise/pop3/run',
- '/var/qmail/supervise/pop3-ssl/run',
- '/var/qmail/supervise/smtp/run',
- '/var/qmail/supervise/submission/run'

and find out something like 'exec /usr/bin/softlimit -m 9000000 '.

Increase the value until 3-4 times but no more than 64000000. Original softlimit have a problem especially on Centos 64bit (version 5 and 6).

3. Run 'telnet localhost 25' for to make sure this port not blocked/inactive. Testing also on port 110, 143, 993, 995, 587 and 465

4. Find error on 'log manager' and 'mail queue'

--------------------
Additional info:

1. Sometimes, after Kloxo-MR update, qmail not work.

You can see in 'Log Manager' for IMAP error or SMTP error like '@400000005187cdc72b428044 tcpserver: fatal: unable to bind: address already used'.

For this situation, need reboot. Or running 'qmailctl stop; qmailctl start' (remember: 'qmailctl restart' not work).

It's ok if appear something like '@40000000518752e21fc74ac4 tcpserver: status: 0/40'

2. Repair qmail:
Code: [Select]
qmailctl stop
yum reinstall *-toaster -y
sh /script/fixmail-all
qmailctl stop
qmailctl start

3. If still not work, run :
Code: [Select]
chmod 4755 /home/vpopmail/bin/vchkpw
qmailctl stop
qmailctl start

==============

NOTE:
- This information not accurate for latest Kloxo-MR (6.5.0.f-2013031825)
- Only command needed:

Code: [Select]
# fix mail issue
sh /script/fixmail-all

# better stop and start instead restart
qmailctl stop
qmailctl start

==============
NOTE:
- Reinstall Qmail-toaster

Code: [Select]
# uninstall toaster
yum remove *-toaster

# remove bin and config
rm -rf /var/qmail/

# install again (including clamav and spamd) and also other applications as dependencies
yum install *-toaster webalizer cronie cronie-anacron crontabs

# run fix mail config (qmail-toaster config and webmail)
sh /script/fixmail-all

# restart (using stop and start better for this situation rather than restart)
# to make stopped and may appear error message
qmailctl stop
# start
qmailctl start

if still something wrong:
Code: [Select]
sh /script/cleanup
sh /script/fix-all
sh /script/restart-all

and check with 'qmailctl stat' and will be appear:
Code: [Select]
[root@viv ~]# qmailctl stat
authlib: up (pid 802838) 27 seconds
clamd: up (pid 802811) 27 seconds
imap4: up (pid 803967) 0 seconds

spamd/log: up (pid 802822) 27 seconds
submission/log: up (pid 802847) 27 seconds
[root@viv ~]#

==============
NOTE: - for to make sure, receipent (gmail, yahoomail and others) not thinking your email as 'spam'
- Activate 'Enable Domainkey' in 'Server Mail Settings'
- In every domain, active 'Enable SPF' in 'EMail Auth' (also active 'Enable DMARC' as optional)
- As to provider to setup 'reverse-dns' for your server IP(s)
- Set 'hostname' with FQDN format (use 'server1.youdomain.com' instead 'server1')

Mustafa,
Qmail-SMTP not work with these settings.
Code: [Select]
#!/bin/sh

NOFILESGID=`id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
BLACKLIST=`cat /var/qmail/control/blacklists`
SMTPD="/var/qmail/bin/qmail-smtpd"
TCP_CDB="/etc/tcprules.d/tcp.smtp.cdb"
RBLSMTPD="/usr/bin/rblsmtpd"

    /usr/bin/tcpserver -v -R -H -l $HOSTNAME -x $TCP_CDB -c "$MAXSMTPD"
    -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp
    $SMTPD $VCHKPW /bin/true 2>&1

SMTP Error (535): Authentication failed.

@40000000517ee180175b31d4 tcpserver: status: 0/500

i saw Spacedust write a tip to change user to root, but then there is a new problem. When somebody add new email i need to run fixmail otherwise the new mail can't send too...

I don't confirm this. It works perfectly for me with all the mods.

Make sure Spam Assassin works as admin, the rest as root.

Spacedust using Centos 5.x Go to Centos 6.X and you'll see it does not work on that port.

What about port 587 ? Do you use dynamic IP ?

No fixed IP. Port 587 does not work on the server, and it should.

I have same problem of insanity.

POP3 and IMAP work, SMTP fails.

Log entries of /var/log/kloxo/maillog are like this:
vchkpw-smtp: vpopmail user not found

I am not on a updated kloxo, this is a fresh installation of Kloxo MR

I have already changed softlimit and reinstalled *-toaster

Looking in the log:

./user_cmd:14:59 May/08/2013: () 7797 '/home/vpopmail/bin/vadduser' [...] sh: /home/vpopmail/bin/vadduser: Permission denied

But why? Permissions seem to be correct

Hello,

I still have not acted in accordance with these guidelines.

My current problem is that when I send email via webmail to gmail or emails with personal provider, It works perfectly but when I send email to yahoo provider, I reseive below failure notice
Code: [Select]
Hi. This is the qmail-send program at xxxx.domain.ltd.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<xxx@yahoo.com>:
Connected to 66.196.118.240 but greeting failed.
Remote host said: 421 4.7.1 [TS03] All messages from xxx.xxx.xxx.xx will be permanently deferred; Retrying will NOT succeed. See http://postmaster.yahoo.com/421-ts03.html
I'm not going to try again; this message has been in the queue too long.
Do you offer that I will act in accordance with these guidelines?
(In case of a disruption in the webmail system may lose my clients)

@WISTFUL,

Have you read http://postmaster.yahoo.com/421-ts03.html and http://help.yahoo.com/kb/index?page=con ... sions=true ?
I am not familiar with mail system settings and I have above issue by kloxo webmail default configurations. Also all mails that will be sent automatically from my server to yahoo, facing with this failure notice error that I have not access to their settings.

Have you click 'Enable SPF' on 'Mail Auth' and ask to your provider for reverse-dns for your ip?.

Error:
