I've just set up a new website and had some email addresses set up alongside it.

Ran them through mailtester.com and have a spam score of 0.8 /10.

I use Wordpress and Cpanel for my website.

Could anyone help me solve them or is this only something my domain provider can help me with?

These are some of the key issues, the main one being the DKIM signature being invalid (thanks in advance):

-0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
This negative score will become positive if the signature is validated. See immediately below.

-1.999 FSL_HELO_BARE_IP_2 IP used in the HELO request
The hostname should be a domain name, not an IP address

-0.865 RCVD_NUMERIC_HELO Received: contains an IP address used for HELO

-1.274 RDNS_NONE Delivered to internal network by a host with no rDNS
This may be a false-positive, please check the reverse DNS test below to confirm or not this issue

-0.01 T_DKIM_INVALID Your DKIM signature is not valid
Have a look at our DKIM test below to know why

[SPF] your website does not allow your server to use your email
-1

Your DKIM signature is not valid

You do not have a DMARC record

Your reverse DNS does not match with your sending domain.
