The way to overcome this is to use the IFS environment variable.
subject='Set UID program scan results'
address="hare...@ergolight-sw.com"
mailcommand="mutt/$address/-s/$subject" ## space replaced by /
IFS="/" ## use / as word separator
$mailcommand << okfff
Some message body.
okfff
Of course you can use any other character that is not in your text
(e.g ~, =, :, %) but do not try to use characters with shell meaning
(e.g. (, ), [, ], <, >, ;, *).

One other way is:
cat <<EOD | $mailcommand
However, the whole $mailcommand idea here is useless, I 'd do (by the way, why
use mutt as a command line mail sender ? I'd use /bin/mail).
#!/bin/bash
subject="`/some/setuid/program/runs/here`"
mailaddr="hare...@ergolight-sw.com"
mailcmd=/usr/bin/mutt
cat <<EOF | $mailcmd $mailaddr -s "$subject"
blah blah
blah blah
EOF
exit 0
