title: PHPMailer EHLO Error
body: <p>I have a problem for a couple of days ago me going crazy, I have a script that sends mails using phpMailer and arsys. </p>
  
  <p>The fact is that the overnight stops working, check the code and seems fine, it's more, it works correctly if I run it from the test server that comes through another IP. </p>
  
  <p>I found that the server was not on any spam blackList and found the reference to be to a PBL, me worry about removing it from there. </p>
  
  <p>Anyway, I still can not send mail from that server and both my other test script I programmed work correctly on development server but not on the production server. </p>
  
  <p>The error that is specifically this </p>
  
  <pre><code>SMTP -&gt; ERROR: EHLO not accepted from server: 
  SMTP -&gt; ERROR: HELO not accepted from server: 220 ESMTP Postfix smtp-04.servidoresdns.net 
  SMTP -&gt; ERROR: AUTH not accepted from server: 250-250-llsg993-a04.servidoresdns.net PIPELINING 250-SIZE 51200000 250-ETRN 250-250-STARTTLS AUTH DIGEST-MD5 CRAM-MD5 LOGIN PLAIN 250-AUTH = DIGEST MD5 CRAM-MD5 LOGIN PLAIN 250-250 8BITMIME ENHANCEDSTATUSCODES 
  </code></pre>
  
  <p>It says it can not authenticate the credentials are fine but since the same script from another server goes perfectly. </p>
  
  <p>Also came through a tcptraceroute to port 25 SMTP server. </p>
  
  <p>Only strange thing I see is that when running </p>
  
  <pre><code>tcptraceroute p 25 smtp.miservidor.com 
  </code></pre>
  
  <p>He says: </p>
  
  <p>Sorry, Local Requested port is already in use. Use P, instead of p, to override. </p>
  
  <p>But after using P instead of p and functions </p>
  
  <p>Anyone shed me some light on this? </p>
  
  <p>Who may be filtering my IP address ??</p>
