And as I have pointed out numerous times already, exim does not offer
all the same functionality as sendmail.  In fact, I said that above -- 
"can't provide the same services as the existing item."  Really, this
selective reading that you are doing, Steve -- purposely ignoring the
parts of my message that you can't find a good rebuttal for -- is
getting annoying.

In order to configure Sendmail to the same extent that one can
configure exim, one does not need to know cf.  I, in fact, know little 
of .cf -- only the parts that map directly from m4 to it, in fact, and 
none of the rewrite rules.  My mc file does not now, nor has ever,
include any raw .cf lines.  Just what can you do in exim.conf that cannot
be done with sendmail.mc?

Which is still irrelevant that it's a layer of abstraction.  Guess
what.  C is a layer of abstraction above assembler, which is the same
above machine language.  Perl is layer above C, on top of that.  This
does not immediately make all Perl programs "evil".

Furthermore, many programs have a module for config-file parsing
linked in.  Why does it suddenly turn evil because one step of parsing 
is done by an external program?

m4 is not buggy.  You have yet to produce even one example of
something that can be done in exim.conf and not sendmail.mc, much less 
a bug in m4 that prevents sendmail.mc from working.
