On a heavily loaded server, this is downright *suicidal*.  spamd/spamc
are used to reduce system load incurred by having to load Perl and parse
all of the configuration files for each message.  With a high mail
volume, this can mean ~3x or more mail volume can be processed on the
same hardware without causing problems.

With your method of making sure mail gets scanned, mail will slowly
build up in the queue until the server runs out of disk space, the MTA
can't process the queue because it's too big, or SA's memory usage
triggers the Linux kernel OOM process killer.  (Exactly which happens
first depends on the MTA and how much physical memory you have.)

On a private server with only a few accounts, this is not an issue.
