SSL / Re: Secure CWP Admin Panel Port 2031
« on: November 17, 2020, 07:10:57 AM »What worked for me. My hostname is server.yourdomain.com.my

I notice an issue with this
vi /etc/dovecot/dovecot.conf - update the cert file path there.

Information / Re: CentOS 8 Support - When or Never???
« on: October 31, 2020, 04:21:49 PM »
I installed the same version of CWP but the database seems to be different. I am not able to import data from CWP running on Centos 7 to Centos 8.
I am not sure if this is a required change. it looks to be a bug.
CentOS 8

Postfix / How to stop unauthorised email from via SMTP server?
« on: October 13, 2019, 09:57:19 AM »
Hi,
We have CWP pro installed in our VPS. We have our mail server running on it too.
Lets assume the domain we are running is abc.com.my
Spammer is able to send email from peter@abc.com.my (this is a valid email id) to peter@adiss.com.my
https://www.wormly.com/test-smtp-server
shows below log.
As long as the user exists in the mail server it allows. if we used nonexistent user then we get below error.
We want every email to be authenticated before sending out. What kind of setup or config is required for us?
Thanks in advance.

E-Mail / LDAP authentication
« on: June 28, 2019, 05:44:55 AM »
Hi,
I have a client using different webapp and they are using single signon with LDAP. I want the email hosted via centos web panel also authenticate using same credential.
Means when user logs in via roundcube. the authentication will be from LDAP server than local postfix mailserver.
Thanks you very much.

E-Mail / Downloading incoming and outgoing email to another server
« on: May 07, 2019, 09:55:21 AM »
Hi,
I have VPS running with CWP. There are abount 50 email user and quite a lot of emails with attachments are being sent/recieved. This is causing the VPS getting filled up.
keeping the email and attachment is important. What can I do other than buying more VPS space?
How can I move the emails somewhere else , maybe locally hosted mail server ?
We have a Synology NAS in the local network. Is there anyway we can backup emails into it ? still should be searchable.
Thanks for your advice. Have a great day ahead !

« on: December 08, 2017, 03:06:23 AM »
Hi Guys,
I am not able to configure the VHOST properly. ideally it should work as expected. Not sure where is the problem.
Some info here, let me know if need more info.
I need to create more domain/subdomain. if VHOST doesnt work then how can I manage ?
