Don't do this! tee will overwrite the mailbox on every new piece of
mail. tee -a is implemented incorrectly on some systems. And the mailbox
format is probably not just one message after another.

Much better is to have two lines:
\mbonner
other-acct at host.domain

The \ turns off all alias interpretation and forces delivery straight to
your mailbox. This is much more efficient than the above pipe, and it
works.
