I've been emailing an account that I know is active and it's a address that receives alot of public emails. I've been emailing for years and not always receiving a reply. However for the first time, this morning I sent an email received the 554.30 reply below. I know the account is busy and active normally until this morning. Can this mean they blocked me? Can this mean their inbox was full and could not receive any incoming mail at that time?
Address not found
Your message wasn't delivered to ***@*** because the address couldn't be found, or is unable to receive mail.
The response from the remote server was:
554 30 Sorry, your message to ***@*** cannot be delivered. This mailbox is disabled (554.30).
System Configuration: Android / Chrome 90.0.4430.66
The Yahoo account may have been disabled according to the error message. This may happen if the account is no longer active for 12 months, or if Yahoo disable it for another reason.
If you've been blocked, you'll not be notified and will not receive any error message. Even if the account isn't disabled, it's possible that your message couldn't be delivered for some reason. I suggest you try sending it again after a few hours.
