VPS: Is there any way to route just one site through its dedicated IP

bcon

I have a VPS which has approx 40 small websites.
I have 5 dedicated IPS.
My most important client has a Dedicated IP.
The other 4 dedicated IPS are share between a handful of sites.
Is there any way to route just one site through its dedicated IP.

If I do the following:
Navigate to WHM: Home -> Service Configuration -> Exim Configuration Manager
2. Click on the "Domains and IP" Tab
3. Enable the "Send mail from the account’s IP address"
4. Click 'Save' at the bottom

Then this works for that one website with its own dedicated IP but reults in errors for all the other sites that are sharing an IP.

The error for all the other websites under Email deliverability is:
The only PTR value for this IP address must be "xyz". This is the name that this server sends with SMTPs HELO command to send outgoing email.
1 unexpected PTR value exists for this IP address.

Any help appreciated

    Did you read this?
    https://support.cpanel.net/hc/en-us/articles/360049187673-How-to-send-email-from-a-dedicated-IP-address

    "The above steps will affect all accounts using dedicated IPs on the server.

    Sending email from a dedicated IP address means that you will need to modify the PTR record for the dedicated IP address to match the account's domain name."

    If you want that only one site is sending using it's dedicated IP you must use /ets/mailips & /etc/mailhelo

    Thanks but I have tried this and whilst it works, it affects ALL the domains on the VPS and creates error messages for those that share an IP. I need this option but for just one domain on one dedicated IP

    Thanks, I have tried this and on the shared IPS Im getting the error

    "The error for all the other websites under Email deliverability is:
    The only PTR value for this IP address must be "xyz". This is the name that this server sends with SMTPs HELO command to send outgoing email.
    1 unexpected PTR value exists for this IP address."

    My host and I cannot fix this error if 4 websites are sharing a dedicated IP, we have tried.

    You can't share a dedicated IP in a cPanel server, unless the IP is assigned to a reseller account.

    Correct - you can't have multiple domains on a dedicated IP address in cPanel or else you'll run into odd behavior like that.

    Wish there was the option to just have one domain on a dedicated ip route its email through its dedicated ip

    There is - you just need to add additional lines to the configuration:

    https://docs.cpanel.net/knowledge-base/email/how-to-configure-the-exim-outgoing-ip-address/#the-mailhelo-file

    Under that mailips section you can see how multiple domains can be configured.  Is that not working for you?

    in /etc/mailips
    domainwithdedicatedip: dedictedip
    *: mainip

    in /etc/mailhelo
    domainwithdedicetdip: rDNSofDedicatedIP
    *: rDNSofMainIP

    in WHM -> Service Configuration -> Exim Configuration Manager -> Domains and IPs
    Send mail from the account’s IP address = Off
    Reference /etc/mailhelo for custom outgoing SMTP HELO = On
    Reference /etc/mailips for custom IP on outgoing SMTP connections = On
