How do you figure? Sendmail is quite happy to take as many addresses on the
command line as you want to feed it... certainly more than will fit in (for
example) a UUCP control file.
You only need one sendmail per <XXX> entries, and on modern UNIX <XXX> is
pretty large. Large enough that the overhead *within* sendmail is going to
dominate.

And then *that* alias would show up in the "received" line. It's an
infinite regress.
I've just started with Majordomo but I've been hacking email long enough to
grok sendmail's behaviour pretty well.
