Ok so, I now have it sending the mail, however when I try to send the mail I get the following error.....
SMTP error from remote mailer after RCPT TO:<email@example.com>:
host myhostname.mydomain.comm [IP ADDRESS]: 550 5.7.1 <firstname.lastname@example.org>... Relaying denied
How can I fix this. As I said, I can sendmail, but cannot recieve it. On easydns, I have told it to use mail.mydomain.com as the mailserver. I am completely confused. Thanks
