Given the sample data i expect regex to return NOTHING it should NOT MATCH anything but unfortunately it does.

NAME
mhmail - send or read mail SYNOPSIS
mhmail [addrs ...] [-body text] [-cc addrs ...] [-from addr] [-subject subject] [-version] [-help] DESCRIPTION
mhmail is intended as a replacement for the standard Berkeley mail program (mail or mailx), which is compatible with nmh. This program is intended for the use of programs such as cron, which expect to send mail automatically to various users. It is also used by various nmh commands to mail various error notifications. Although mhmail can be used interactively, it is recommended that comp and send be used instead to send messages. When invoked without arguments, it simply invokes inc to incorporate new messages from the user's maildrop. When one or more users is specified, a message is read from the standard input and spooled to a temporary file. mhmail then invokes post with the name of the tempo- rary file as its argument to deliver the message to the specified user. The -subject subject switch can be used to specify the "Subject:" field of the message. By default, mhmail will read the message to be sent from the standard input. You can specify the text of the message at the command line with the -body text switch. If the standard input has zero length, mhmail will not send the message. You can use the switch -body "" to force an empty message. Normally, addresses appearing as arguments are put in the "To:" field. If the -cc switch is used, all addresses following it are placed in the "cc:" field. By using -from addr, you can specify the "From:" header of the draft. Naturally, post will fill-in the "Sender:" header correctly. FILES
