In man procmailex, the following recipe is used to create a directory

Is the message piped to mkdir?
Is there a better way of executing a program without having the
message piped to it?
Lots of ways. You can do things in backquotes, you can assign variables
whose contents are the stdout of a command line, etc.
Those are _other_ ways, but they are not _better_ ways. In particular,
if you're not using the output of the command, making it the action of a
recipe with the 'c' and 'i' flags is more efficient than using a variable
capture recipe or a variable assignment with backquotes. Those both
require procmail to create an extra process and pipe that a simple
:0 ic
* conditions
| command here
doesn't. (The extra process is needed to avoid deadlock when filtering
the message through the command.)
