Please help in understanding why spamassassin in hung or entered into a busy
loop. When I formatted the html tags in the email by separating the tags using
newline, the spamassassin executed as expected. Hence, thought that there might
be issue with HTML Parser and upgraded to the latest version(i.e.0.8). But the
issue still persists.
Please let me know how to proceed further.
