I have a similar issue. I was flagged by some crappy company that ID'd my IP address as spam (Spamhaus was the **** that got me). I was able to remove my email from their list but have had nothing but issues sending since but only from Live Mail. Here is what I have been getting Subject 'Re: Reply to your "French Door - with door jam" Ad on Kijiji' Server Error: 550 Server Response: 550 5.1.1 *** Email address is removed for privacy *** recipient rejected, relaying not allowed here. Server: 'smtp.telus.net' Windows Live Mail Error ID: 0x800CCC79 Protocol: SMTP Port: 587 Secure(SSL): No HELP PLEASE :(
