The example they provide looks dangerous to me:
return_path = $sender_address_local_part=$local_part=$domain=\
${hash_8:${hmac{md5}{SECRET}{${lc:\
$sender_address_local_part=$local_part=$domain}}}}\
@$sender_address_domain
Local parts in email addresses have a maximum length of 64 characters,
yet that could easily expand to something considerably larger than 64
characters...
