 * This is the Error message I receive when I try an automatic delivery from my 
   website. I have verified everything and everything is fine.
 * What I think is that they would have to send me an SPF code with all the IPS 
   of the servers they use to include them in an SPF.
 * The Error message is the following.
 * This message was created automatically by mail delivery software.
 * A message that you sent could not be delivered to one or more of its
   containers.
   This is a permanent error. The following address(es) failed:

 * Hi Manuel!
 * The error indicates that the email is blocked because your sending domain is 
   on a blacklist that the receiving provider doesn’t accept (it won’t even send
   it to spam).
 * Who is your SMTP provider? Have you verified with your host that no sending IPs
   are on a blacklist (they should check them all not just one).
 * Thanks!
