But also looks quite clumsy in some mail clients. And with a small
filter called from (e.g.) a procmail recipe it would be possible
to replace text/html parts with a <pre>...</pre> version of a lynx
/ links -dump of the original code before passing it to the spam
analyzer. Afterwards, the original code {sh,c}ould be restored.

Of course, such a solution would be quite expensive and therefore
most probably not be usable at high volume sites.


Ciao
