There are lots of formats in use.  Ones distributed with AMDS can have the form
    To: +dist+/this/is/a/dist/list/file@do.main.name
or, if the dist list is published, whatever its alias is:
    To: my-foobar-list@do.main.name
These are all reply-able addresses, in that you could send mail to
either of them @do.main.name, and the mail would be redistributed.

Note that this is in fact illegal; the correct form omits the domain
name, so it's
    To: Pederasty-Enthusiasts:;
This form is intentionally(?) opaque: you can't send mail to it and have
it redistributed.  If there were any recipients listed, they'd
individually have domain names, so the result could look like
    To: Pederasty-Enthusiasts: joe@foo, jane@bar, jack@hill;
I once maintained a mail UA that would abbreviate such lists, no matter
how long, for header typeout as
    To: Pederasty-Enthusiasts:
which all of its users found pretty convenient at the time.

There's nothing wrong with this address, either.  RFC822 says it's OK:
the text outside the <> address doesn't have to be a person name.  And
it's replyable, in that mail sent to that address will be redistributed
to the list.
