long time email account not found

I set up my website here a couple of decades ago, and still use it. It has an email address associated with my domain name that I then routed to my gmail account.  Google has notified me that they will no longer allow this. I'm trying to login to start checking mail on Homestead and clean up old messages, but can't locate where or how to do that... any suggestions on how to access my email? Thanks... t
