I have a WordPress website that is sending emails to me through a contact form. The From address in the emails uses the same domain name of the website.
Currently the emails are being treated as spam, probably because the SPF setting for the domain name doesn't include the mail server being used by the website.
How can I find out the IP address of the mail server used by the website?
Once I've got that, I can add the IP address to the SPF DNS record for the domain.
