  • Perhaps you're (your external IP) on black list of this domain. Could you try  telnet 25 from another IP? If failed again it means problem with receiving SMTP server not yours.

  • Check if your domain is on blacklist (https://mxtoolbox.com/blacklists.aspx)

    You should try to contact the domain another way and let them know its not working.
