I believe Exim does *not* run your pipe through a shell by default, so
your pipe is the moral equivalent of

% cat ">>" /var/mail/test1234

cat is presumably failing because there's no such file as ">>".

You could either set use_shell on the pipe transport used for your alias
file, or set the alias to this:

test1234: "| /bin/sh -c /bin/cat >> /var/mail/test1234"

...or words to that effect. Untested, YMMV.
