62to use IPv4 addresses only.
63.It Fl 6
64Force
65.Nm
66to use IPv6 addresses only.
67.It Fl A
68By default,
69.Nm
70tries to send the message to only one address,
71even if the host has more than one A or AAAA record.
72If this option is specified,
73.Nm
74tries to send the message to all addresses.
75.It Fl i

105facility.
106The default is ``user.notice.''
