Hi

I am trying to set up a new e mail account in Windows Live Mail from my own domain not hosted by Sky with my SMTP server being mail.skyusermail.com. I have other similar e mails set up using the same parimeters which work perfectly but this one when I send e mail to one of my other addresses returns this message to the receiving e mail
This is the AVG E-mail Scanner program.

I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.
The e-mail server has responded with the following error:

-------------------------------------------------------------------

peter@peterdenyerservices.co.uk: We do not relay without RFC2554 authentication.
-------------------------------------------------------------------

Your e-mail message is being returned to you in the next part of this
message. Try to send the message again.

Should you need assistance, please contact your administrator or your
Internet service provider.

You can also verify e-mail client's settings, for instance:
- whether your SMTP authentication has been configured
- whether you have provided correct SMTP server name
- whether the sender's address responds to the used SMTP server domain

Anyone have any idea what I am doing wrong?
