Re: Quizzic: Spam equivalent to EICAR test virus proposal.

Just for comparison:

SpamAssassin defines what's called the Generic Test for Unsolicited Bulk
Email (GTUBE).  It's defined as a string matching the regular expression

XJS\*C4JDBQADN1\.NSBN3\*2IDNEN\*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL\*C\.34X

appearing anywhere in the message body, after decoding and HTML rendering.

(I write the regular expression rather than the string itself so that any
of you running spamassassin won't score this message at 1000 points.)
