That seems correct from my reading of the documentation. I can't comment
in more detail because I don't actually use such features myself.

That seems to be correct. The 'virtual' table will map from a "virtual"
address to any address, including a unique local one.

That would be necessary to allow different "virtual robots" in the Sympa
process to host mailing lists with the same name.

This seems to be a correct assessment to me. It's worth noting, though,
that Postfix supports both "postfix style" and "sendmail style" virtual
domains.

Postfix style implies that local alias definitions are /not/ visible to
the delivery process. This is what the virtual user to unique alias will
work with.


You can also use "sendmail style" virtual domains. This involves adding
the domain name to 'mydestinations', at which point mail delivered to
anyone at that domain will be treated as a local delivery.

This is the mode that I use for supporting the three domains I have.

It would be quite possible for Sympa to work with this mode as well. The
alias entries would need to be in the format:

   foo: "| /usr/lib/sympa/bin/bouncequeue address@concealed"

This wouldn't work correctly with lists of the same name in different
virtual robots but, for me, that's not actually needed.
