Trying to locate the source of an error

Hi,
        I'm using a procmail script that I got off the web, and it works 
fairly well except that I get an intermittent error.
        I run mailstat, and it will show that some mail has gone through 
and dropped into my /var/spool/mail/msaroff file, but when I bring up 
pine to look at it, it's not there.  If I type out the 
/var/spool/mail/msaroff file, the message will show up, but it will be 
screwed up.  The headers will be something like this (please note that 
I'm typing from memory):
          wealthforu\.com|\
webcert\.com|\
webdreamer\.com|\
webguides\.com|\  
webtrend4u\.com|\
wehelpyou\.com|\
wesmark\.com|\
wobat\.com|\
 ...etc
To: msaroff(_at_)pca(_dot_)net
Subject blah blah blah.

        Does anyone out there have any idea what I should look for to see 
what is causing this?  I've look at this part of the recipe (basically a 
long list of domain names), which starts as follows:
# LLV (Softfacts, Inc.)
:0:
* ^(From.|Reply-To:|Message-ID:|Received:).*[^0-9A-Za-z](205\.254\.16[4-7]|\
          1daystar\.com|\

        I've checked to make sure that all the parentheses are closed, 
and they are.  I'm assuming that this some subtle sort of error, but I 
can't pick it up.
