I have been having problems sending e-mail through Customnet. I am using MS Outlook 2003 and when attempting so send e-mail the error message I get is:
Task 'mail.customent.co.uk - Sending' reported error (0x800CCC78) : 'Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 530 Authentication required. Please login using SMTP-AUTH before sending mail.'
