.SH NAME
mconnect \- connect to SMTP mail server socket
.SH SYNOPSIS
.LP
.nf
\fBmconnect\fR [\fB-p\fR \fIport\fR] [\fB-r\fR] [\fIhostname\fR]
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmconnect\fR utility opens a connection to the mail server on a given
host, so that it can be tested independently of all other mail software. If no
host is given, the connection is made to the local host. Servers expect to
speak the Simple Mail Transfer Protocol (\fBSMTP\fR) on this connection. Exit
by typing the \fBquit\fR command. Typing \fBEOF\fR sends an end of file to the
server. An interrupt closes the connection immediately and exits.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-p\fR\fIport\fR\fR
.ad
.RS 10n
Specify the port number instead of the default \fBSMTP\fR port (number 25) as
the next argument.
.RE

.sp
.ne 2
.na
\fB\fB-r\fR\fR

produces an effect similar to  \fBtelnet\fR(1) to port number 25.
