What this means for your email list
Should you accept addresses at this domain?
Probably not. Throwaway services like tmailinator.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
tmailinator.com has no DMARC policy, so receivers have no instruction on what to do with mail that fails authentication. Large mailbox providers now expect bulk senders to publish one.
