I've been reading over the Regular_Expressions.htm file that installs with SpamFilter and have been trying to figure out how to make my keywords do two things, but I keep failing miserably (due to being a novice and not great with programming).  Any help would be grand.  I think I just don't know how to construct regular expressions at all.

1) I'd like to make a keyword string be case insensitive.  Currently, mixed case is getting through.  For example, if I have "human growth hormone" as a keyword string and "Human Growth Hormone" is a string in the email, it goes through because the cases don't match.

2) Similarly, if a string has a line break in it, it too is getting through.  For example:

human
growth
hormone

is getting through because the message hard coded line breaks.

Before you all flame me, I did read the Regular Expressions file several times and spent a couple hours trying to do these otherwise simple operations.  Apparently I just don't get it so I beg your collective forgiveness and earnestly request whatever help you can give.

Thanks,

Dan et. al,

Thanks for your reply.  I'm definitely going to start implementing some of the more advanced techniques as seen here on the site.  I've put one filter in place that works with the eleven-character comment tags.  However, some crap keeps coming in.

I'd still like to know how to make keywords case-insensitive though, as a lot of spam that reaches my inbox has certain keywords in the subject line that, if filtered case-insensitive, may reduce spam further.

Thanks again,
