I have never seen another e-mail with an iCloud address but a test e-mail from the salesman in the shop was received OK. However when I tried to send a message from OE it failed and I got this message
"Your message was not delivered because the Domain Name System
(DNS) for the destination computer is not configured correctly.
The following is a list of reasons why this error message could
have been generated. If you do not understand the explanations
listed here, please contact your system administrator for help
*The host does not have any mail exchanger (MX) or
address (A) records in the DNS.
The host has valid MX records, but none of the mail
exchangers listed have valid A records.
There was a transient error with the DNS that caused
one of the above to appear to be true.
You may want to try sending your message again to see if the
problem was only temporary.*
Thanks everyone. Have just tried again using .com, hopefully problem solved.
As a matter of interest why in my address list of over 1500 names I haven't seen another icloud one. I assume that ipad and other Mac users have an additional address and wondewr if there is a good reason for this.
