About Mail Header

To use SendMail/ReadMail effectively with BASP21, let's become familiar about "mail header".

• From:
  Sender's mail address.  Next 3 types are allowed.
  name@domain
  real_name <name@domain>
  name@domain (real_name)
  It seems to be displayed on a mailer, the part of real_name  only. . You can name it anything for real_name.
  
  
• To:
  Receivers' mail address.  All mail addresses you specified here, would be visible from individual receiver.  If you worry about this matter because of security or privacy reason, you should better to set only one address for each mail.  In addition, using BCC is much better to send a mail to many people at one time.
  Use it in this way;
  mailto = "id1" & vbtab & "id2"& vbtab & "id3"
  
  
• Cc:
  Means "Carbon-Copy".  The address(es) where you want to send the copy of mail. Mostly, this is used when you want to inform someone that such mail has sent for some reason.
  Use it in this way;
  mailto = "main-id" & vbtab & "cc" & vbtab & "id1" & vbtab & "id2"& vbtab & "id3"
  
  
• Bcc:
  Blind Carbon-Copy.  This is the same feature that CC has, but this header will be eliminated by mail server during transaction.  Thus, there is not even the means that knows to whom this mail was sent.  Mostly, this is used when you want to inform someone that such mail has sent for some reason but hide it from receiver, intentionally.   I know some people always put themselves mail address in BCC, to check the correct send mail transaction.  Not bad idea, ha ?!
  Use it in this way;
  mailto = "main-id" & vbtab & "bcc" & vbtab & "id1" & vbtab & "id2"& vbtab & "id3"
  
  
• Date:
  The date of mail transmitted enters.  Sometimes, it becomes very important that when the mail has been transmitted. Well, BASP21 takes care of it.
  
  
• Subject:
  The title of mail itself.  When you omitted, you still have a choice, it will be a very vain mail or a mysterious mail.  So, just try to enter somewhat you can title it.
  
  
• Received:
  Mostly it is attached to the beginning of header area and shows a route of mail delivered.
  Each mail server takes care of it.
  
  
• Mime-Version:
  Informs the Version of MIME(Multipurpose Internet Mail Extension). (e.g. version 1.0)   BASP21 takes acre of it.
  
  
• Content-Type:
  Informs the type of mail itself.  It depends on each content, and BASP21 takes care of it.  However, if you really want to determine it, you can do it in this way;
  mailto = "id1" & vbtab & ">Content-Type: text/html"
  
  
• Content-Transfer-Encoding:
  The type of how mail content was encoded.  Such case that content is binary,   the mail should be delivered with the header including Content-Transfer-Encoding as base64, uuencode, or etc..  It also depends on each content, and BASP21 takes care of it.
  
  
• Message-Id:
  Several mailers have the function of "thread" that lists all receiving mails by the relation that was replied.  To do so, each mail has to be identified from the entry of Message-Id, and this must be done by mailer.  However, BASP21 does not send this header.
  Use it in this way;
  mailto = "id1" & vbtab & ">Message-Id: thread-1"
  
  
• Reply-To:
  If you want to determine the return address which you expect to receive reply and it is different from the mail address you specified at From field, then enter it here.   When "Reply" button has been pushed, most mailer behaves to send the selected mail to the mail address displayed at Reply-To field.
  Use it in this way;
  mailto = "id1" & vbtab & ">Reply-To: me@domain"
  
  
• Sender:
  Actual sender's name.  If this header is empty, BASP21 does not send anything.
  Use it in this way;
  mailto = "id1" & vbtab & ">Sender: BASP21"
  
  
• X-Mailer:
  The information of mailer itself.  In case of BASP21, it shows like "BSMTP. DLL".
