On busy systems, parsing the values out of the From_ line in stead of
calling date (once or more) per message, could mean an important
difference in the number of messages per second it can handle.
Parsing From_ in procmail, with a truckload of recipes, is faster than
calling date? Would it also be faster if some basic functionality of
date was included in procmail?
In a secure environment, `date` doesn't even have to be available.
That's the shortcoming in procmail, IMHO. Parsing From_ is a workaround,
not a solution.
