Why not

    $text_footer = $html_footer = '';

    if ($Sender =~ /mydomain.com/) {
        $text_footer = ".";
        $html_footer = "<b>.</b>";
    }

    append_text_boilerplate($entity,$text_footer,0) if ($text_footer);
    append_html_boilerplate($entity,$html_footer,0) if ($html_footer);

This can be extended easily with more stanzas to specify footers.  It
saves running the two append commands when there is nothing to do.

I agree with what Jan-Pieter Cornet said.  The logic problem of what to
do with a message to multiple recipients would need to be solved before
a solution can be coded.

My first thought is to use what I wrote up there, and have another if
condition or two that sets the footer variables back to '' if certain
other conditions are met, e.g. $Sender =~ /bob\@mydomain/.

Sometimes the logic is interesting to discuss.
