COMMAND

    mailtool

SYSTEMS AFFECTED

    SunOS 5.5

PROBLEM

    The  SunOS  5.5  mailtool  seems  to follow symlinks when enabling
    the vacation feature, so if you

    ln -s /var/mail/luser ~/.forward

    and then enable vacation  it copies /var/mail/luser to  ~/.forward
    and appends "|/usr/bin/vacation me"  to it (and moves  the symlink
    to ~/.forward..BACKUP.
