Sending a new email with maildrop/mailbot

I'm in the process of moving from procmail to maildrop*

Anyway, one of the things I do is scan certain emails for a particular 
string and if found, extract that line and sent it to my phone's text 
message email address. A suitably munged procmail recipe to do this is:

[email protected]
:0BHc :
* ^From:.*REDACTED.*
* ^Subject:.*key subject
* .*key text.*
{
  	MSGTEXT=`formail -I "" | grep -i "keytext"`
  	:0
  	| (formail -brt  -I 'From: [email protected]' \
  	-I 'Subject: Example' -I "To: [email protected]" ; \
  	echo $MSGTEXT) | /usr/sbin/sendmail -t

}

So far, for the Maildrop equivalent, I've come up with using mailbot 
(from reading the man page, it appears reformail is not the tool for 
this) is:
if (/^From:.*REDACTED/ && \
      /^Subject:.*key subject/ && \
      /.*key text/:b && \
{
      `grep -i "key text" > .tmpmailfilter`
      cc "|/usr/local/bin/mailbot -t .tmpmailfilter \
        -A 'From: [email protected]' \
        -N -s "Key" /usr/sbin/sendmail -f '' [email protected]"
      `rm .tmpmailfilter`
}

This works so my only concern is that it is not optimal. Is there a way to 
avoid using the temporary file by using a variable like in the procmail 
recipe? Also, I tried setting the destination with [email protected] 
but if IIRC, correctly, that caused it to go to the original sender as 
well.

Thanks in advance for any comments or suggestions.

* Why the move? Unfortunately, the latest Mac OS X (10.9) has become more 
strict in strcpy error checking and procmail built under 10.9 will error 
on more complex recipes - currently using the procmail built under 10.8 
but figure with no procmail development work in over 10 years, I may be 
living on borrowed time).
