Just to let you know I own a number of domains and any one of them may have brought you here; if that is the case welcome.
I use the domain fintan.com for my emails and as the home page for any of the other domains that I may own which are not operating in their own right .
If you have come to this page because you have been getting SPAM from the fintan.com domain all I can say is I am sorry for your inconvenience. However all my systems are secured and somebody has been claiming that SPAM and PHISHING emails originated from this domain; if you check the email carefully you will see they did not come from the fintan.com domain!
The domain fintan.com has a Sender Policy Framework (SPF), uses
Domain Keys Identified Mail (DKIM) and
Domain-based Message Authentication, Reporting, and Conformance (DMARC) .
SPFis a simple email validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchanges to check that incoming mail from a domain comes from a host authorised by that domain's administrators. The list of authorised sending hosts for a domain is published in the Domain Name System (DNS) records for that domain in the form of a specially formatted TXT record.
Whilst SPF adds information to a message envelope DKIM actually encrypts a signature within the message header. When you forward a message, portions of that message's envelope can be stripped away by the forwarding server. Since the digital signature stays with the email message, because it's part of the email header, DKIM works even when a message has been forwarded.
DMARC works with SPF and DKIM to authenticate mail senders and ensure that destination email systems trust messages sent from your domain. Implementing DMARC with SPF and DKIM provides additional protection against spoofing and phishing email. DMARC helps receiving mail systems determine what to do with messages supposedly sent from your domain that fail SPF or DKIM checks.
Email spam and phishing often use forged sender-addresses, so publishing and checking SPF, DKIM, and DMARC records can be considered anti-spam and anti
