There is one:

[EMAIL PROTECTED] is an alias to [EMAIL PROTECTED] +
[EMAIL PROTECTED], so that mail to [EMAIL PROTECTED] gets
distributed to both addresses.

When [EMAIL PROTECTED] 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:<[EMAIL PROTECTED]>
  RCPT TO:<[EMAIL PROTECTED]>

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

just my 2�
