Hiding text with "

[Olivier Coutu]

We have started seeing some clickbait spam that hides the suspicious 
text behind /<img alt/ tags, e.g.

https://pastebin.com/SLMyFvmN
The text /Optima Tax Relief: Do You Still[...]/ is visible in the email 
in thunderbird since the image does not load, but spamassassin's body 
rule does not trigger

/body        T_OPTIMA  /Optima Tax Relief/i/

Using ctrl-f does not find that text either. Other than rawbody, are 
there other options?
