GTUBE


The GTUBE is a 68-byte test string used to test anti-spam systems, in particular those based on SpamAssassin. In SpamAssassin, it carries an anti-spam score of 1000 by default, which would be sufficient to trigger any installation.
The contents of the string are as follows:
XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X
and should be placed in the message body of an RFC 5322 compliant email message, without any line breaks or whitespace.
Checksums for the string are as follows:
