I keep getting this message with pretty much every email where I try to mention a website or url in the body text, which is damn annoying as you can imagine that one would quite frequently try to refer to the web when emailing...: "An error occurred while sending mail. The mail server responded: r7hL1r00710UxZ5017hMzC message rejected due to spam or virus. If you believe this is in error please login to your portal or contact your ISP support team.. Please check the message and try again." I am often forced to go through emails I respond to or forward and delete all hyperlinks in order to be able to send it. Can I also say that plusnet has the worst customer service in the UK.
