title: could hyperlinks in emails be getting changed by the destination mail server
body: <p>We send out password-reset emails to business partners who use our intranet. The body of the email contains a hyperlink:</p>
  
  <pre><code>  `http://www.ourdomain.com/ResetPassword.aspx?token=....`
  </code></pre>
  
  <p>But some of the people who receive these emails are saying there's an extra dot in the domain name:</p>
  
  <pre><code>  `http://www.ourdomain..com/ResetPassword.aspx?token=....`
  </code></pre>
  
  <p>I do not see where that could be happening in the program I've written. I store the base url in the web.config:</p>
  
  <pre><code>  `http://www.ourdomain.com`
  </code></pre>
  
  <p>and attach the name of the aspx page and append the token to it.</p>
  
  <p>Are there any corporate anti-virus programs out there which deliberately <em>mangle</em> hyperlinks discovered in the body of emails, to render them invalid and thus unclickable?</p>
