Is mailmunge running the Perl filter script at every stage of the milter 
callbacks even if there is no code for that stage in the filter script? 
For example, if i have or don't have code for filter_helo() in the 
filter does it make a difference on the overhead/traffic of postfix -> 
mailmunge -> filter?
