This wasn't working because /etc/aliases was being applied before
checking for a real local user name, so with the rules

*: edmund
edmund: ege

in /etc/aliases, and no mention of ege, a local part like foobar
causes a cycle: foobar -> edmund -> ege -> edmund -> ...

Now, exim seems to resolve a cycle by rewriting exactly once, which
fails in this case because "edmund" is a not a real local user.

It might be helpful if exim -bt -d10 could give some kind of warning
about there being a cycle. It took me a while to work out what was
going on here.

It seems that using "*" in /etc/aliases is not the way to do it
because probably you want to check for local users before applying the
default rule. So probably I should use a separate director in
exim.conf added after all the other directors. What I have done is to
duplicate the director quoted above, but with the file name
/etc/aliases2, where that file has a single line "*: edmund". I think
it's working now.

Perhaps this solution, or a neater one, should be given in the FAQ, if
it's not already there.
