      Depending on your situation you may want to try some of these possible solutions

      1. Make sure with your email administrator that your email server is setup to allow smtp relaying from trusted local internal IP addresses.
      2. Make sure that your computers IP address is on the list of trusted clients on the email server.
      3. Some email servers may allow relaying only if you log in and check email atleast once from a given IP address. In this case, you can check your POP3 email first before sending SMTP email from a new computer.
      4. Some email servers allow smtp relaying only if you log in and check email within the last 1 hour/day etc… In this case, you should use the pop3 authentication method to send email.
      5. Some servers require you to authenticate before sending email. In this case, use the smtp or java authentication methods.
      6. Microsoft Exchange: make sure that your exchange server is configured to allow smtp relaying either for trusted IP addreses, or for users that are authenticated.
      7. Make sure that your email administrator has configured your ip address / account to send internal and external email.
      Hope it helps
