mutt question

["Theisen, James E" <james.e.theisen@xxxxxxxx>]

Hello:
        Using mutt in an automated (Linux) process to send out event 
notifications. All is well except that I see confusion between who is "To:" and 
who is "cc:". 
Here's a piece of the script:

        export user1="user1@xxxxxxxxxxxxx"
        export user2="user2@xxxxxxxxxxxxx"      
        export user3="user3@xxxxxxxxxxxxx"
        export user4="user4@xxxxxxxxxxxxx"      
        export distribution-list="${user2} ${user3}"
                .
                .
        mutt -s"subject-text"   \
        -apath/attachment.file  \
        ${user1}  admin<path/message-body.txt   \
        -c${distribution-list}  \
        -c${user4}

All the mail gets to all the addressees but:
                The To: addressees are:   ${user1} admin ${user3)       #user3 
is the tail-end of the distribution-list
                The cc: addressees are:   ${user2} and ${user4}         #user2 
is the first element of the distribution-list

        Seems like only the first element in the distribution-list gets cc:, 
the rest go to To:
