Hi there, I wonder if you can help. I have been trying to e-mail my brother in Australia recently but they are coming back as undeliverable. It is only this one, I am getting all my other e-mails and receiving. I do get his e-mail to me. I have sent the main message for the last attempt but have others each time.but it is quoting my and my brothers e-mail so have deleted this. I will forward if necessary to get this hopefully resolved. I don't know how to get to the postmaster.
This is the mail system at host mx-out.tt.xion.oxcs.net.
I'm sorry to have to inform you that your message could not
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.
