Why do I get a "recipient not acceptable to your SMTP server" error?
This error usually occurs when the recipient or one or more of the recipients of your e-mail mail message has an invalid e-mail address.
For example, if you forget to put an ampersand "@" in the e-mail address, the SMTP server will automatically reject this and will not send the e-mail message. You will need to go through the recipient or recipients of your e-mail message to make sure the syntax (username@yourdomain.com) is correct
Tips:Do not forget to put @ in the e-mail address.
