There is one:

dude at a.example.com is an alias to dude at b.example.com +
girlfriend at b.example.com, so that mail to dude at a.example.com gets
distributed to both addresses.

When dude at a.example.com sends an email which is undeliverable, he gets a
bounce, which gets expanded and forwarded by a.example.com and finally
arrives at b.example.com as follows:
  MAIL FROM:<>
  RCPT TO:<dude at b.example.com>
  RCPT TO:<girlfriend at b.example.com>

Of course, this is a silly configuration, but it is real-life
experience.

just my 2¢
Frank.
