Hello all,
having a bit of a challenge and hoping to get some help here. I host my site on VPN with one provider (A) and host domain and email on another (B). All my personal emails come and go through provider B and domain mail.domain.com. I use some forms on my site with provider A that are sent through PHP mail() and use server.domain.com.
These form emails seem to have a high spam score and I am wondering how I can improve deliverability. I am not sure if I have to add a SPF record somewhere, or set MX record for server.domain.com, or something else. Is there a way to set the form to use my mail.domain.com instead?
These are some of anti abuse headers:
X-AntiAbuse: Sender Address Domain - server.mydomain.com
X-Get-Message-Sender-Via: server.mydomain.com: authenticated_id: myusername/only user confirmed/virtual account not confirmed
X-Authenticated-Sender: server.mydomain.com: myusername
X-Sender-Warning: server.mydomain.com has no MX records
Authentication-Results: semfq01.mfg.siteprotect.com; dmarc=none header.from=hotmail.com
X-SpamExperts-Class: unsure
Please let me know if there is anything else I should provide.
Thanks
