.SH DESCRIPTION
.B Spost
is the program called by
.B send
to feed the message in
.I file
to
.B sendmail
for delivery.  In fact, many of
the features attributed to
.B send
in its manual page are performed by
.BR spost ,
with
.B send
acting as a preprocessor.
Thus, it is
.B spost
which parses the various header fields, appends
\*(lqFrom:\*(rq and \*(lqDate:\*(rq lines,
and finally feeds the message to the MTA.
.B Spost
will not normally be called directly by the user.
.PP
.B Spost
searches the \*(lqTo:\*(rq, \*(lqCc:\*(rq, \*(lqBcc:\*(rq,
\*(lqFcc:\*(rq, and \*(lqResent\-xxx:\*(rq header lines of the specified
message for destination addresses,
.PP
If a \*(lqBcc:\*(rq field is encountered, its addresses will be used for
delivery, and the \*(lqBcc:\*(rq field will be removed from the message
sent to sighted recipients.  The blind recipients will receive a newly
constructed message with a copy of the original message attached.
MIME rules are used for encapsulation.
.RB ( spost
invokes
.B send
to send the Bcc message.)
.PP
The
.B \-alias
.I aliasfile
switch can be used to specify a file that spost
should take aliases from.  More than one file can be specified, each
being preceded with
.BR \-alias .
In any event, the alias file, set with the `Aliasfile' profile entry, is
read first.
.PP
The
.B \-verbose
enables the output of informational messages.
This option sets \-watch, too.
.PP
The
.B \-watch
switch adds the `\-v' switch to the
.B sendmail
invocation.
.PP
.B Spost
constructs the \*(lqFrom:\*(rq line of the
message from the user's login name and the full name from the GECOS field
of the passwd file.
An example is \*(lqFrom: Dan Harkless <dan>\*(rq.
.PP
If you set the
.B $SIGNATURE
environment variable.
Its value overrides the full name from the GECOS field.
.PP
If you specify a \*(lqFrom:\*(rq
line manually in the message draft.
It will be used as provided.
However, a \*(lqSender:\*(rq header with the user's
.B real
address will be added.
.PP
Note that this applies equally to \*(lqResent\-From:\*(rq lines
in messages sent with
.BR dist .
.PP
Your MTA is supposed to care to fully qualitfy the addresses
with the correct domain name.
.PP
The draft is filed to the folders in the Fcc headers by
.BR refile .
