I have contacted Yahoo! and they told me to contact Lycos.com but they don't deal with Lycos.co.uk (where my friend sends messages from) and I get a failed delivery message when I try to contact Lycos.co.uk. The email address is valid because she still sends emails to me.

This is the message I receive whenever I reply or email her:

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.

<fayevenables@lycos.co.uk>:

212.78.202.7 does not like recipient.

Remote host said: 554 Rcpt-To validation failed: RCPT TO not accepted:

Giving up on 212.78.202.7.
