title: reply emails are bounced due to URL in content
body: <p>I have a client who communicates with me via email. Crazy, I know.</p>
  
  <p>Here is the issue: When I send him an email from Mac Mail — <em>with my URL in the footer</em> – he receives it. However, when he tries to <strong>reply</strong> from his gmail account, my server bounces it back to him. The error is "554 rejected due to spam content". (a false-positive)</p>
  
  <p>I can not collect the Spam Checker data from his email headers, as he is not tech savvy. I can not duplicate the error using a gmail account of my own. I have eliminated all possible problems, except the URL in my footer, which triggers this every time.</p>
  
  <p>My email server is: 01-ah-r28u33-ss05.alphahosting.com</p>
  
  <p>His gmail server is: mail-ob0-f172.google.com</p>
  
  <p>Both of these (and also my test gmail server) are shared servers and have some blacklist reports. However, I have no such problems from other clients. My concern is that this could be a <strong>reporting</strong> problem, and I am failing to hear from those who would rather delete my email than give me a call. I think that you can understand my concern.</p>
  
  <p>Please help, and do let me know if you need any other data that I might add in here.</p>
