You are almost there. The line in
.forward
that is
| /home/me/Documents/webtest/mail/strip.pl < $1
means that the script already gets its input from STDIN, so the redirection part is unnecessary. Change it to :
| /home/me/Documents/webtest/mail/strip.pl
and everything should work, or at least, this error should be eliminated. The error in the mail to root meant that the "recipient"
/home/me/Documents/webtest/mail/strip.pl > $1(almost your script) had errors. This means that either your script did not compile properly (make sure you check this every time you modify the script!!!!) or that sendmail could not start it with the redirection (I guess the error in this case).
A good idea is to dry-run a check against your script every night with some known good input so the mail does not get silently discarded. I do this with my home-made spamfilter (maybe soon to be replaced with a serious solution).
