RealSender | dedicated smtp server


 RealSender.com offers an online check tool
 to validate your SPF settings sending an email message:

 1. send an email to spf@tester.realsender.com
 2. check online the SPF validation results
     (it will take a minute to appear)

 During verification, a prefix is added to the subject
 if the message is not authenticated correctly.



 RealSender.com promotes the limit
 on the number of recipients per message, to reduce
 the risk of sending cc/bcc to many addresses.
 
 We share a list of 300 @spam-box.com addresses for testing.
 The messages will reach a "black-hole" mailserver.
 
 You can use them at your convenience
 to check how many recipients per message
 your smtp server allows the sending.
