DKIM and SPF for your mail in Plesk

Updated on 4 November 20261 min read

DKIM puts a digital signature on your outgoing mail. Together with SPF it keeps your mail out of spam.

Go to Mail and open the Mail Settings tab.
Click your domain and tick Use DKIM spam protection system to sign outgoing email messages.
Click OK. Plesk sets the required DNS records itself if your DNS is with us.

Is your DNS elsewhere? Then copy the DKIM and SPF records from DNS Settings to your DNS manager.

Also add a DMARC record: TXT record _dmarc with v=DMARC1; p=none
