In views/admin/mail_options.rhtml :

Added a self-clearing DIV so that fieldset border actually contains the checkboxes:

Original:
<% actions.keys.sort.each do |group_id| >
<fieldset style="margin-top: 6px;"><legend><strong><= l(Permission::GROUPS[group_id])
></strong></legend>
< actions[group_id].each do |p| >
<div style="width:170px;float:left;"><= check_box_tag "action_ids[]", p.id, p.mail_enabled?
>
<= l(p.description.to_sym) >
</div>
< end >
</fieldset>
< end %>

Changed:
<% actions.keys.sort.each do |group_id| >
<fieldset style="margin-top: 6px;"><legend><strong><= l(Permission::GROUPS[group_id])
></strong></legend>
< actions[group_id].each do |p| >
<div style="width:170px;float:left;"><= check_box_tag "action_ids[]", p.id, p.mail_enabled?
>
<= l(p.description.to_sym) >
</div>
< end >
<div style="clear: both;"></div>
</fieldset>
< end %>

It's the simple <div style="clear: both"></div> that's been added.

It's a small thing. ;) Thanks for this cool, cool project!
