What this means for your email list
Should you accept addresses at this domain?
Probably not. Throwaway services like mailsac.com give out inboxes that people abandon within minutes, so a signup with this domain rarely turns into a customer. Blocking it at the form keeps fake accounts and wasted emails out of your list.
Sender authentication
mailsac.com has DMARC in monitoring mode (p=none). It collects reports but does not yet block spoofed mail, so the domain is easier to impersonate.
