Mail Delivery Failure

Hi,

Any mails i am sending with invoice plane is being rejected by the server & not being delivered. I am using a custom theme for the quote & the email bounce message is below.

A message that you sent was rejected by the local scanning code that
checks incoming messages on this system. The following error was given:

This message was classified as SPAM and may not be delivered (spam report:
HTML_MESSAGE=0.001, MIME_HTML_ONLY=1.105, NO_RELAYS=-0.001,

Please refer to http://wiki.apache.org/spamassassin/Rules/ for details
regarding the rules matched and how to fix them.

Also the code for the custom email is this
