.SH "VERSION"
1.0.0 (21-10-1997)
.SH "DESCRIPTION"
\fBSMTPclient\fR is a minimal SMTP client that takes an email message body and
passes it on to a SMTP server (default is the MTA on the local host). Since it
is completely self-supporting, it is especially suitable for use in restricted
environments.
.PP
A typical usage is as a MTA emulating program on a dedicated webserver.  There
it is usually called from within a CGI program to receive a mail (constructed
by the CGI program out of a HTML form) and to forward it to the actual
mailserver.
.SH "OPTIONS"
.Ip "\fB\-s\fR, \fB--subject=\fR\fI\s-1STR\s0\fR" 4
Specifies the \f(CWSubject:\fR header. This gives the message a title. Default is
no subject.
.Ip "\fB\-f\fR, \fB--from=\fR\fI\s-1ADDR\s0\fR" 4
Specifies the \f(CWFrom:\fR address header. This is the logical senders address.
Default is ``\f(CWdaemon\fR'\*(R', which is probably wrong.
.Ip "\fB\-r\fR, \fB--reply-to=\fR\fI\s-1ADDR\s0\fR" 4
Specifies the \f(CWReply-To:\fR address header. This is where replies should be
send to. Default is no such header.
.Ip "\fB\-e\fR, \fB--errors-to=\fR\fI\s-1ADDR\s0\fR" 4
Specifies the \f(CWErrors-To:\fR address header. This is where delivery
problems should be reported. Default is no such header.
.Ip "\fB\-c\fR, \fB--carbon-copy=\fR\fI\s-1ADDR\s0\fR" 4
Specifies the \f(CWCc:\fR address header. This can contain one or more addresses
(seperated by comma) to which one copy of the message is send to. Default is
no such header.
.Ip "\fB\-S\fR, \fB--smtp-host=\fR\fI\s-1HOST\s0\fR" 4
Specifies the name or \s-1IP\s0\-address of the \s-1SMTP\s0 host to connect to. This is the
host where the \s-1MTA\s0 is running to which the message is forwarded. By default,
the mail is send to the \s-1SMTP\s0 daemon on \f(CWlocalhost\fR or to the host specified
in the environment-variable \f(CWSMTPSERVER\fR if exists.
.Ip "\fB\-P\fR, \fB--smtp-port=\fR\fI\s-1NUM\s0\fR" 4
Specifies the port of the \s-1SMTP\s0 host to connect to. Default is port 25 (smtp).
.Ip "\fB\-M\fR, \fB--mime-encode\fR" 4
Use \s-1MIME\s0\-style translation to quoted-printable (base 16).
.Ip "\fB\-L\fR, \fB--use-syslog\fR" 4
Log errors to system's \fIsyslog\fR facility instead of \fIstderr\fR.
.Ip "\fB\-v\fR, \fB--verbose\fR" 4
Turn on verbose logging to \fIstdout\fR.
.Ip "\fB\-V\fR, \fB--version\fR" 4
Display the program version.
.Ip "\fB\-h\fR, \fB--help\fR" 4
Display the usage page.
.SH "RESULTS"
The program terminates with a non-zero exit status in case of errors.
