[exim] Aliases

I have this in exim.conf for aliases:

drop_solo_alias:
driver = redirect
allow_defer
allow_fail
data = ${if exists{/etc/virtual/$domain/aliases}{${lookup{$local_part}lsearch{/etc/virtual/$domain/aliases}}}}
file_transport = devnull
group = mail
#pipe_transport = virtual_address_pipe
pipe_transport = devnull
retry_use_local_part
#include_domain = true


Occasionally one of the email addresses inside an alias will be over
quota generating an annoying bounce. The email addresses over quota
will be listed in /etc/over_quota_email. Is there a way to have this
skip attempting to deliver to any email addresses listed in that file?
