Before trying BETA-4, will I need to make any changes to my existing
mimedefang-filter, to accommodate this new function?

I already do some EHLO/HELO checking, and am wondering if those existing
checks will no longer work where they are (in filter_sender), if I need to
move those specific checks into filter_helo, or what.  Will filter_sender
still be passed the value of $helo?

Thanks.  :)

Ken
