The new string expansion items that will be added in 4.67 (see
http://www.exim.org/bugzilla/458) are what you need. You'll get:
address_data = \
${lookup{$local_part}lsearch*{/var/mail/exim/virtualdomains/$domain}}
data = ${reduce \
{${map {${addresses:$address_data}}\
{${quote_local_part:${local_part:$item}\
${if match_domain {$item}{+local_domains}\
{$local_part_suffix}}}\
@${domain:$item}}}} \
{} {$value, $item}}
You get a leading comma (i.e. an empty item) but that's harmless. Perhaps I
should implement a "join" item too.
However, a better solution would probably be some transform_address option
that would be expanded once for each address *after* internal interpretation
and qualification of unqualified addresses in accordance with the relevant
options, and/or some magic auto_keep_affixes that would cause
$local_part_suffix and $local_part_prefix to be kept on addresses routed to
routers that accept them. Hmmm...
