It’s happening very often that gmail blocks email sent from this domain because of this reason:
Starting November 2022, new senders who send email to personal Gmail accounts must set up either SPF or DKIM. Google performs random checks on new sender messages to personal Gmail accounts to verify they’re authenticated. Messages without at least one of these authentication methods will be rejected or marked as spam. This requirement doesn’t apply to you if you’re an existing sender. However, we recommend you always set up SPF and DKIM to protect your organization’s email and to support future authentication requirements.
I have a email servers from different provider and i’ve add there this record:
v=spf1 a mx include:_spf.forpsi.com ~all
But the good people there told me that i need to protect my dns record with public key - Can you help me with this pls? Thanks…
