*sigh* Fixed. Which takes care of the main problem. I am an idiot.
Sorry, should've cut'n'wasted these lines.

*yuck*
This is something that I positively hate with exim: String expansion.
Worse than perl with leaning toothpick syndrome. However, when it does
what I want it to do, it is fine ;)
Since $local_part_suffix contains the "+", your new_address expression
is a little buggy, and can be shortened to $value$local_part_suffix.
This handles the cases "mailbox+foo", "mailbox" and "first.last+foo"
just fine.
For the mailbox+bar case with the explicit alias, a suffixless
director is needed, giving
system_aliases:
debug_print = "domain_aliases for $local_part@$domain"
driver = aliasfile
file = /etc/aliases
search_type = lsearch*
modemask = 002
system_aliases2:
driver = smartuser
new_address = "${\
lookup\
{$local_part}\
lsearch*\
{ /etc/aliases }
{$value$local_part_suffix}\
fail\
}"
suffix = "+*"
suffix_optional = yes
to solve the task presented.
The drawback that I can see is that the system_aliases2 director would
honor the file even if it were world writeable. The smartuser director
doesn't do file, pipe or other special deliveries anyway, right?
Thanks for your assistance. I hope that this solution will do what we
intend, and doesn't have nasty misfeatures.
Greetings
Marc
