  I am afraid you are confused on this one.  Spaces are not technically part of
addresses, so 'sendmail' never 'matches' a space.  The space is treated only
as a token separator in tokenizing an address, but is never incorporated into
any of the tokens.

Any address which is rewritten by:

R$*at$*		$:$1@$2

will be rewritten in exactly the same way by

R$* at $*	$:$1@$2

In fact both rewrite rules have the identical internal representation
once 'sendmail.cf' has been read and converted to internal form.

Just remove all such rules.  They cause more problems than they solve, and
today mail entering the internet with 'at' addresses is quite uncommon.
You don't need those rules any more.
