but don't just remove it. alias expansion should only happen once,
otherwise, aliases such as
foo foo, bar
will result in duplicates:
[before filter]
foo => foo, bar
[after filter]
foo, bar => foo, bar, bar
thus bar gets the message twice.
so you need to put the option in the after the filter smtpd (the 10025
listener).
more generally, if you daisy chain N filters, then no_address_mappings
should be set in all smtpd listeners but one.
by default, people want alias expansion to happen at last (as close to
delivery as possible). this is more important for aliases that expand to
a lot of addresses. another argument is so that the filter sees a
"virgin" message. this is however debatable, as that would mean filters
should be at the edge, which is an unnecessary requirement. I believe
aliases should be split into two parts: reception time aliases (for
aliases that should have the same policy as the target address, as in
your case), and delivery time aliases (large lists, or aliases that need
to have their own policies. I use multiple addresses that get different
mail, and have different FP acceptability. but I don't use aliases for
this. I just use different accounts. after all, MUAs today support
multiple accounts).
