[exim] dangerous html tag filtering

Hi Everyone -

I was looking at doing some dangerous html tag filtering (like ifram,
embed, script, etc)....

Has anyone got any suggestions on how to do this the most efficient way?
- I was looking at the regex option in exiscan (different to this list,
I know) - but the expressions would be complicated (nice if I could
convert everything to lower case first) -

Any suggestions???


Cheers,
Andrew.
