formail problem...

This seems like a simple problem, but it's got me stumped.

I'm trying to add RFC2369-compliant headers to some of the lists that
pass through my server, for better handling by various MUAs.  (The
procmail list is of course no problem, but spam-l, isp-*, etc need a
little help.)  At present, I've got recipes building variables like:

    :0 E
    * ^Sender:(_dot_)+spam-l(_at_)\/peach.ease.lsoft.com
    {       
        POST = "spam-l(_at_)$MATCH"
        HELP = "spam-l-request(_at_)$MATCH"
        ARCHIVE = "http://$MATCH/scripts/wa.exe?LIST=SPAM-L";
        SUBSCRIBE = "listserv(_at_)$MATCH?body=subscribe spam-l"
        UNSUBSCRIBE = "listserv(_at_)$MATCH?body=signoff spam-l"
    }

Then later on, I've got:

    FMARGS=''

    :0
    * POST ?? .+
    { FMARGS = "${FMARGS} -A\"List-Post: ${POST}\"" }

    :0
    * HELP ?? .+
    { FMARGS = "${FMARGS} -A\"List-Help: ${HELP}\"" }

    :0
    * ARCHIVE ?? .+
    { FMARGS = "${FMARGS} -A\"List-Archive: ${ARCHIVE}\"" }

    :0
    * SUBSCRIBE ?? .+
    { FMARGS = "${FMARGS} -A\"List-Subscribe: ${SUBSCRIBE}\"" }

and finally:

    # for testing...
    :0
    * FMARGS ?? [-]
    { LOG="FMARGS = ${FMARGS}${NL}" }

    :0
    * FMARGS ?? [-]
    { VERBOSE=on }

    :0 fhw
    * FMARGS ?? [-]
    | formail "${FMARGS}"

    VERBOSE=off

And lo and behold, formail is complaining.  The log says:

FMARGS =  -A"List-Post: spam-l(_at_)PEACH(_dot_)EASE(_dot_)LSOFT(_dot_)COM" 
-A"List-Help: spam-l-request(_at_)PEACH(_dot_)EASE(_dot_)LSOFT(_dot_)COM" 
-A"List-Archive: http:
//PEACH.EASE.LSOFT.COM/scripts/wa.exe?LIST=SPAM-L" -A"List-Subscribe: 
mailto:listserv(_at_)PEACH(_dot_)EASE(_dot_)LSOFT(_dot_)COM?body=subscribe 
spam-l" 
-A"List-Unsubscribe: 
mailto:listserv(_at_)PEACH(_dot_)EASE(_dot_)LSOFT(_dot_)COM?body=signoff spam-l"

What am I doing wrong?
