Just to let you know I own several 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 may not be in operation.
If you have come to this page because you think you have been getting SPAM from the fintan.com domain, all I can say is I am sorry for your inconvenience but all my systems are secured. 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.
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). SPF is 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 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-phishing techniques.

PS. If you are interested in the origins of the name Fintan then this is what I understand:
In Irish mythology Fintan mac Bóchra (modern spelling: Fionntán), known as "the Wise", was a seer who accompanied Noah's granddaughter Cessair to Ireland before the deluge. Bóchra may be his mother or may be a poetic reference to the sea.
He was one of only three men in the expedition, along with fifty women, so he, Cessair's father Bith, and the pilot, Ladra, had sixteen wives each. Fintan's wives are named: Cessair, Lot, Luam, Mall, Mar, Froechar, Femar, Faible, Foroll, Cipir, Torrian, Tamall, Tam, Abba, Alla, Baichne, and Sille. He married Ebliu later. His only son was Illann.
His wives and children were drowned when the flood arrived but he survived in the form of a salmon, remaining a year under the waters in a cave called Fintan's Grave. He then turned into an eagle and then a hawk then back to human form. He lived for 5500 years after the Deluge, becoming an advisor to the kings of Ireland. In this capacity he gave advice to the Fir Bolg king Eochaid mac Eirc when the Tuatha Dé Danann invaded and fought in the first Battle of Magh Tuiredh.
He survived into the time of Fionn mac Cumhail, becoming the repository of all knowledge of Ireland and all history along with a magical hawk who was born at the same time as him. They meet at the end of their lives and recount their stories to each other. They decide to leave the mortal realm together sometime in the 5th century, after Ireland was converted to Christianity.
Due to his ability to shape-shift into a salmon and his honorific title as, "The Wise", Fintan mac Bóchra is sometimes confused with a similarly named animal figured in Irish mythology more commonly known and referred to as the Salmon of Wisdom. (From Wikipedia)
I don’t think my parents knew this when they called me Fintan but hey its an interesting myth to be named after.
