If you set up Exim as suggested in
and the references it points to, you won't need to bother with aliases
at all for Mailman, and you won't have this problem.

Exim is not recognizing that addresses of the form
local_part+suffix at ... should be delivered as if +suffix is not there.

In your case, using aliases, I *think* your


router needs the following:

local_part_suffix = +*

either that or you need aliases like

wil-mailing-bounces+*: "|/var/lib/mailman/mail/mailman bounces
wil-mailing-confirm+*: "|/var/lib/mailman/mail/mailman confirm

but it is much better to set up a router and transport for mailman as
discussed in the material referenced in the FAQ or at
