The forthcoming release of Exim has a mechanism for iterating over a
list of addresses. It picks out the "working" part of each address (i.e.
"user@domain"). If you want to pick off either part, you could do it
with a regular expression.
I suppose some operators that did the picking for you might be useful -
something like ${domain:xxxxx} and ${local_part:xxxxx}.
Idea noted.
