Sorry, should have added this to the essay I already wrote. It is the error message I get when my emails won't send using Evemail.
"The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'XXXXXXX@evemail.net'. Subject 'problems with Evesham email', Account: 'Jane's account', Server: 'smtp.freeserve.com', Protocol: SMTP, Server Response: '550 Administrative prohibition', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79"
