[Mimedefang] What is the order of things that occur

[Steve Campbell]

Alan,

Thank you,

Being relatively new to Perl and completely new to MimeDefang, any example 
helps me understand both. All of my threads, so far, seem to turn in to very 
long lengths, but the various opinions and ideas make me consider the many 
ways, right or wrong, to do the same thing.

I am most thankful to all.

Steve
