DNS Setting

Hi, I need a little help setting up my DNS settings.

My domain is on Namecheap and I orginally had all my DNS Settings set to Digital ocean Which is where I installed the panel.

I Now what to use Cyberpanel for my DNS settings for my domain, but its installed on Digital ocean.

Heres my current set up can someone please advise on the changes that I need to make.

I tried switching out the DNS settings on name cheap with my cyber panel NS records but that deleted the website and panel

Did you get a chance to read https://blog.cyberpanel.net/2018/02/24/how-to-register-private-name-servers-on-namecheap-or-godaddy-with-cyberpanel/

yes, I tried that

I attached a photo thread showing the settings

You need to upgrade them to

ns1.yoursite.com
ns2.yoursite.com

When i did that the site no longer worked

IP in DO seems to end in 4, but in NameCheap, your IP does not seem to end in 4. It seems to end in 1 and 2. Similarly on CyberPanel side your ns1 and ns2 IP ends with 1 and 2, please make sure you use your VPS IP.

The ones ending in four is my DigitalOcean VPS IP the one ending in 1 & 2 are my cyber panel DNS IP should i change my cyberpanel ip to match the DO vps one?

Sorry, but what do you mean by CyberPanel DNS IP? Where ever IP is required it should be your VPS IP or the IP of VPS where you are planning to run DNS server.

Ok i changed it to my vps ip i think it works now. I still however cant get rainloops to work it just says cant send mail.

heres the log

How do I check for or adjust the RDNS?

Only your provider can set RDNS for you.

any ideas on how i can fix this?

Here’s some updates

The dovecot.conf file

protocols = imap pop3
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/home/vmail/%d/%n/Maildir

ssl_cert = <cert.pem
ssl_key = <key.pem

namespace {
type = private
separator = .
prefix = INBOX.
inbox = yes
}

service auth {
unix_listener auth-master {
mode = 0600
user = vmail
}

unix_listener /var/spool/postfix/private/auth {
    mode = 0666
    user = postfix
    group = postfix
}

user = root


dovecot.pem has 2 certficates in it


This is the main.cf file

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
