I think this comes down to personal opinion in the end. I have grown to
appreciate SQL, you still prefer UNIX filesystem tools. That's all
right, both can work fine.
But not having a database server isn't necessarily faster -- MySQL
takes a trivial amount of CPU on our server, and it has the advantage
that for queries it does not need to open and close each file. If you
have done a "mailq" on a busy mail server or "lpq" on a busy print
server (both sendmail and lpd use ("filesystem databases"), you can
appreciate that there can be appreciable time involved in accessing
large numbers of files.
Checking a single file for accepting/delaying a message is quick,
though, no doubt.
