Two equivalent recipes behave differently

This may be a pretty simple mistake, I don't see why the first recipe works 
perfectly fine:

        :0 B
         * Content-Type: image/
         | (formail \
            -rA "Precedence: junk" \
            -I "From: Mail Delivery Subsystem 
<MAILER-DAEMON(_at_)atmedia(_dot_)net>" \
            -I "Subject: Non-delivery notification" \
            -A "X-Loop: mailloop(_at_)atmedia(_dot_)net" ; \
                echo "This is an automated message regarding the non-delivery 
of your message."; \
                echo "Your message contains a binary attachment, which the 
recipient has chosen "; \
                echo "not to accept, and has consequently been discarded. "; \
                echo " "; \
                echo "postmaster(_at_)atmedia(_dot_)net" \
           ) | $SENDMAIL -oi -t

while the second one, having exactly the same formail but just a different 
pattern, fails:


        :0
         * > 16384
         | (formail \
            -rA "Precedence: junk" \
            -I "From: Mail Delivery Subsystem 
<MAILER-DAEMON(_at_)atmedia(_dot_)net>" \
            -I "Subject: Non-delivery notification" \
            -A "X-Loop: mailloop(_at_)atmedia(_dot_)net" ; \
                echo "This is an automated message regarding the non-delivery 
of your message."; \
                echo "Your message contains a binary attachment, which the 
recipient has chosen "; \
                echo "not to accept, and has consequently been discarded. "; \
                echo " "; \
                echo "postmaster(_at_)atmedia(_dot_)net" \
           ) | $SENDMAIL -oi -t


Here's the excerpt from the log file:

procmail: [10215] Tue Aug 26 16:39:05 1997
procmail: Error while writing to " (formail \
            -rA "Precedence: junk" \
            -I "From: Mail Delivery Subsystem 
<MAILER-DAEMON(_at_)atmedia(_dot_)net>" \
            -I "Subject: Non-delivery notification" \
            -A "X-Loop: mailloop(_at_)atmedia(_dot_)net" ; \
                echo "This is an automated message regarding the non-delivery 
of your message."; \
                echo "Your message contains a binary attachment, which the 
recipient has chosen "; \
                echo "not to accept, and has consequently been discarded. "; \
                echo " "; \
                echo "postmaster(_at_)atmedia(_dot_)net" \
           ) | $SENDMAIL -oi -t"

The following rule is 

        :0 c
        /dev/null


Any help would be greatly appreciated.
