Undelivered E-mail Problems

  Kilty 09:55 02 Jun 09

I am having problems with e-mails to and from a particular address. I try to send them to a BTinternet address but get the following report back:

delivery temporarily suspended: host
mx2.bt.mail.yahoo.com[] refused to talk to me: 451 VS3-IP5
Excessive unknown recipients - possible Open Relay

I would be greatful if someone could tell me if it is my ISP (orange.fr) or BTinternet's problem.

Thanks in advance for any help given.

Can you get them to send you an e-mail and if so press the reply button and send a message from that and see if it sends Ok.

I have now had time to test if I can reply to an e-mail from the BT address that keeps blocking my e-mails. They still do not recieve them and I get the same message back.

I have also tried with e-mails with and without attachments.

The question I have is: do I need to contact my ISP or does the person who is not recieving my e-mail have to contact theirs, to get this sorted?

Thanks in advance for any help given and also the help already recieved.
