Unfortunately, the gofirecrest.com domain name has been the victim of a joe-job in the past (I suspect I am not alone!)
In this scam, a spammer places the victim's email address (or, in my case, a random name plus the gofirecrest.com domain name) in the "from" address of the email. This has resulted in hundreds of junk emails landing in my mailbox every day, half of them bounces from spam filters.
Unfortunately, there is nothing I can do to prevent you receiving the emails but I can assure you that I do not send spams. However, if you visit the joe-job link (above), you will find several suggestions of things you can do to fight back. I have tightened up on my mail forwarding now so if you make a mistake on my email address, I will not receive your communication
This appears to have died down but if it picks up again, I'll add a message to the home page
