Basic mail gateway services
Here are some basic mail gateway services:

- Domain Key (DKIM) Verification: DKIM verification services verify the authenticity of incoming email messages by checking the digital signature of the sender's domain.
- Sender Policy Framework (SPF) Verification: SPF verification services verify the authenticity of incoming email messages by checking the IP address of the sender's mail server against a list of authorized IP addresses.
- Domain-based Message Authentication, Reporting, and Conformance (DMARC) Verification: DMARC verification services verify the authenticity of incoming email messages by checking the digital signature of the sender's domain and reporting any suspicious messages.
