I get the following from BSDI 1.0's man page:

     -I    Forces mail to run in interactive mode even when input isn't a ter-
           minal.  In particular, the `~' special character when sending mail
           is only active in interactive mode.

Also, SunOS has this interesting flag:

     -r address    Pass address  to  network  delivery  software.
                   All tilde (~) commands are disabled.
