.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
`From:' and `Date:' 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 `To:', `Cc:', `Bcc:', `Dcc',
`Fcc:', and `Resent\-xxx:' header lines of the specified
message for destination addresses,
.PP
.B Sendmail
is called witch all recipients, expect these from Bcc-field
.br
.B sendmail
.B \-i
.RB [ \-v ]
.I recipients ...
.PP
If a `Bcc:' field is encountered, its addresses will be used for
delivery, and the `Bcc:' 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
If a `Dcc' field is encountered, the field will be removed
befor sending the mail.
.PP
The `Aliasfile' profile entry
can be used to specify one or more files that spost
should take aliases from.
.PP
Aliasing is done on any address-field will.
The address-fields are `From:', `To:', `Bcc:', `Dcc'
or rather the `Resent\-xxx:' versions of this fields.
.PP
The
.B \-verbose
switch enables informational messages.
For example, the `\-v' switch will be added to the
.B sendmail
invocation.
.PP
.B Spost
puts the
.RI ` Default-From '
profile entry in the `From:' line of the message.
If `Default-From' is not set,
.B spost
constructs the `From:' 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 `From: Dan Harkless <dan>'.
.PP
If you set the
.B $SIGNATURE
environment variable.
Its value overrides the full name from the GECOS field.
.PP
If you specify a `From:'
line manually in the message draft.
It will be used as provided.
A `Sender:' header with the user's
.B real
address will be added, if the `From' line don't contain a address
from the user
.RI ` Alternate-Mailboxes '.
.PP
Note that this applies equally to `Resent\-From:' lines
in messages sent with
.BR dist .
.PP
.B Spost
takes care about full qualitfy addresses,
in every address-field.
Your MTA is supposed to care to add the correct domain,
if there is no after aliasing.
.PP
The draft is filed to the folders in the Fcc headers by
.BR refile .
