E-Mail / Email rejected: Quota exceeded (mailbox for user is full)
« on: June 19, 2015, 02:13:17 AM »
Hello, I am facing an issue that one of my email accounts suddenly could not receive any email since a day ago, a bounced-back email has been sent back to sender with the following message. In fact, my VPS still having 75GB free disk space and the email quota limit is set to default which is 0 value.

Your message to <> was automatically rejected:
Quota exceeded (mailbox for user is full)

The rest of email accounts has no such problem. Any idea how to get this resolved? Thanks.

Hello BullTen, tried install the script onto CWP but having the following at the end of installation:

Starting httpd: httpd: Syntax error on line 506 of /usr/local/apache/conf/httpd.conf: Syntax error on line 3 of /usr/local/apache/conf.d/mod_security.conf: Cannot load modules/ into server: /usr/local/apache/modules/ undefined symbol: ap_log_error

I disabled the mod_security and restart the httpd again, I got this then

Starting httpd: httpd: Syntax error on line 506 of /usr/local/apache/conf/httpd.conf: Syntax error on line 2 of /usr/local/apache/conf.d/rpaf.conf: Cannot load modules/ into server: /usr/local/apache/modules/ undefined symbol: ap_log_rerror

Any idea how to get this resolved? Many thanks.

Hello there, I noticed that after I have rebuilt the mail server all the emails been blocked i.e. no email receive/send. I checked the mail log and noticed the following at smtpd_recipient_restrictions:

warning: unknown smtpd restriction: ""

It should be "reject_rbl_client", once I changed that the mail services are back to normal. Hope CWP will fix this soon.

Thank you.

Updates / Re: 0.9.8 release should have these upgrades !!!
« on: February 13, 2015, 08:21:58 AM »
CWP had been updated to version 0.9.8, installed the pgsql but how am I going to manage the databases & the users on pgsql??

After created a additional new user account with a domain name assigned, I noticed that the CSF firewall is somehow crashed when logging onto new user account i.e. CWP or the FTP access; it make the whole VPS become like hang and unresponsive.

I have to log in onto the web console which provided by hosting provider and execute the command "service iptables stop/restart" in order to make the VPS back to normal. Everything working fine if CSF firewall being disabled.

Anyone facing the same problem like me?

Installation / Re: I cant connect to server after finish install CWP

I managed to get this problem resolved at last by myself.  ;D

I booted my VPS from the web console, execute "service iptables stop" and check if CWP is up. When CWP is up, execute the command "service iptables restart" and follow by "csf -e"; now everything seems back to normal.  ::)

Hope this help someone who having the same issue like me.

I also facing the same problem. I had setup a VPS with 4GB RAM and CentOS 6.5 64bits, CWP version 0.9.7 installed. This VPS has the clamav, amavis, antispam, csf firewall, varnish enabled.

Initially everything working fine but few hours ago all the services i.e. web, email, ssh & CWP went down, could not even connect through SSH. I have to connect from the web console provided by vendor to execute the command "service iptables stop" then everything up again. However, I noticed as long as I tried to start the csf firewall the VPS will down again.

For now, I have to leave the csf firewall disabled. Any idea what has causing this problem??

CentOS Configuration / Re: How to setup user quotas ?
« on: December 30, 2014, 10:49:47 AM »
I had the quota installed and set the necessary settings on /etc/fstab, but sometimes when restarted the server and re-login onto CWP it showed the quota notification again.

How can I set the quota permanently onto the server??
