Recipient Undeliverable (TT512) message.

[algy1]

Hello.

I am trying to understand what the following error message means:

Subject: Undeliverable: Availability for.....(name, dates etc data redacted).....
This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

obscured for customer security
    host mx.talktalk.net [62.24.202.42]
    SMTP error from remote mail server after RCPT TO:<obscured for customer security>:
    550 5.1.1 kYKSrcHeBmK5y Recipient Undeliverable (TT512)

This message was received by and forwarded to me by a person with whom I have exchanged emails previously using the same email address's, without any problem.

I'd be grateful if someone could shed some light on this and advise on any fix.

I am a TalkTalk mail only customer now.

Thanks.

The TT512 message is from the inbound TalkTalk mail server saying that the mailbox for Alan is not available for delivery.  The mailbox is currently active on the mail platform so it's either full, rejecting your mail or just temporarily unavailable for delivery.

You might like to try again later. Let us know what happens.
