A friend has created two new mailboxes and alias's for them on his
Blueyonder (formerly Telewest, now Virgin Media). He's had his Blueyonder
account for a few years now and his main email address is an
@blueyonder.co.uk one, so we assumed his new mailbox should also follow that
pattern instead of an @virginmedia one.
Anyway, he sent me a test message from each of the new mailboxes and I
received both of them OK. The problem comes when I try to reply to them and
I get the following error message:
Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

195.188.53.99 does not like recipient.
Remote host said: 550 Administrative prohibition - unable to validate
recipient
Giving up on 195.188.53.99.
What exactly does that mean? I know that 195.188.53.99 is a Blueyonder
machine so the mail is leaving my ISP but failing at Blueyonder. He created
the mailboxes about 2 hours ago and, like I said, can send from them without
any problem. Does it take longer for Blueyonder systems to process and set
up the POP3 side - can't see it meself, but you never know eh?

Is this something that my mate has/hasn't done or does he need to ring
Blueyonder and get them to sort it?
Cheers,
John.
