E-mail check for your domain
Checks whether your domain can receive e-mail properly and is protected against forged senders: MX, SPF, DMARC and optional extensions.
What the records do
MX specifies which servers accept e-mail for your domain. SPF lists the servers that may send on your behalf. DMARC tells recipients what to do with e-mails that fail these checks and sends you reports. Since 2024, Google and Yahoo have required SPF, DKIM and DMARC from bulk senders.
