550 TrashMail: Recipient address rejected: User unknown

[maxlamer]

Hi,

I received this error from a number of my trashmail accounts, on
@cryptotrademail.com; @0box.eu; and @objectmail.com

I verified each and they exist. I got the same error message:
"Address not found
Your message wasn't delivered to [email protected] because the address couldn't be found, or is unable to receive mail."

Would appreciate any help as most of my trashmail accounts seem dead.

Best regards
