This is entirely as documented (grep spec.txt for "duplicate" - it's all
there). Exim does not do duplicate deliveries except to pipes that have
*different* immediate parents. You would get two deliveries for:
testexim1: |/some/pipe
testexim2: |/some/pipe
There are several reasons for not doing duplicate deliveries to
mailboxes. One is the idea that mostly, people don't want them. Consider
cases like:
postmaster: joe
hostmaster: joe
and messages sent to both postmaster & hostmaster. The other
consideration is handling errors. The current implementation just
remembers that it has delivered to such and such a mailbox. It would
have to remember how many times it had done so, and, in the case of
address redirection, which particular copy it had or had not delivered.
And if one copy succeeds and one fails, do you send a bounce message or
not? I didn't want to have to think that one out.
