update: tachyon makes a good point in his reply to this reply. If you think your data set may contain such a catch, make sure you follow his advice :)

I really shouldn't have written the whole thing for you, but whatever, I'm in a good and helpful mood. This could most likely be done in less code using the 'find' command in combination with perl's inline editting, but I don't know enough about such things. Note that I copped out by simply slurping each file into memory one at a time. You could rescript it to do line-by-line editting if you wish, though you'd have to add usage of a temporary file. 

#!perl -w

use strict;
use File::Find;

find( \&handle_it, '/foo/bar' );

sub handle_it {
    return unless m!\.html\z!;

    my $name = $File::Find::name;

    open( my $fh, '+<', $name )
        or (warn("open on $name failed: $!\n") and return);
    my $content = do { local $/; <$fh> };
    $content =~ s!foo\@there\.com!bar\@here\.us!g;

    seek($fh, 0, 0) or die("seek on $name failed: $!\n");
    truncate($fh, 0) or die("truncate on $name failed: $!\n");

    print $fh $content;

    close($fh) or die("close on $name failed: $!\n");
}
