Email Problem?

[roosta21]

My friend is having a problem sending and recieving email. This started two days ago. He has recieved a couple but when I try to send him one I kicks the message back to me and this is what it says:

This is the Postfix program at host mxo4.broadbandsupport.net.

I'm sorry to have to inform you that your message could not be
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The Postfix program

<eyell@eufaular.com>: [eufaular.com]: Name or service not known

[vass0922]

is the email address you're sending to @eufaular.com?

If so, their DNS is hosed
http://www.dnsstuff.com/tools/lookup...ar.com&type=MX

There's no MX record

What type of service is this?

A good, simplified description of MX records

the above error message says please send mail to postmaster.
Does this meant the isp for the mailbox? how would i obtain the email address for the postmaster?

Usually, it would be postmaster@somedomain.com, but now that everyone and their brother has setup domains, not everyone has that user created. Even so, the postmaster you need to contact is the one with the bad MX record - who wouldn't get your email anyways, because of the bad MX record!
