How to send a test spam message?

I know, it is common stuff but for someone it could be helpful.

We can use generic test for unsolicited bulk email (GTUBE) and send message with the following string:


19-04-2013 18-51-34

Basically the GTUBE is supported by many anti-spam solutions (except WatchGuard) such as:

  • Symantec BrightMail19-04-2013 18-07-37
  • Cisco Ironport

19-04-2013 18-13-59

  • Microsoft Forefront Protection for Exchange
The error that the other server returned was:
550 5.7.1 Message rejected due to content restrictions
  • Commodo Antispam Gateway
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;550 GTUBE found in message. See

Similar way can be used also for a malware test message (EICAR test file):


Enjoy testing ;).
