 If I connect to the sendmail daemon(port 25) can I add headers manually?

 Lets say:
   connected to server.com sendmail 8.8.8 ready..
   HELO myserver
   pleased to meet you myserver
   MAIL From <me@myserver.com>
   RECPT To: <someone@server.com>
-> HEADER X-Name: "Here is goes: This is Header X-Name"
   DATA
   begin to write and end with a dot
   TEST MESSAGE
   .
   Quit
   closed ...
   
   How this HEADER X-Name: "Here is goes: This is Header X-Name" goes manually in telnet prompt at mail server port 25???
 
 thanks,

depends on the deamon/service answering on port 25, if it has a command for that you can, otherwise you only may add this as part of the DATA section.

soory but I know that the daemon runs on port 25. I want to know how I can enetr everything manually including the headers too. What a Mailer Agent does through its instructions included inside its binary code I want to do them manually. Can I? I know the answer is YES but I do not know HOW: comas, brackets, paranthesis etc. I should use, format of entering them etc.
 
 I will connect throught telnet host.smtp.server.com 25
 
 thanks,

250-DSN
250-ONEX
250-ETRN
250-XUSR
250 HELP
>>> MAIL From:<me@my.computer.com> SIZE=22
250 <me@my.computer.com>... Sender ok
>>> RCPT To:<someone@server.com>
250 <someone@server.com>... Recipient ok

Sendmail expects that everyline up to the first blank line in the DATA section of your message is a header.  A line beginning with white space is assumed to be an continuation of the previous header.  If you are adding custom headers, the RFC-822 convention is to prefix them with 'x-'.  Below is an example of a (very) simple mail message.


>>>MAIL FROM: POSTMASTER@mail.domain.com
250 <POSTMASTER@mail.domain.com>... Sender ok
>>>RCPT TO: POSTMASTER@mail.otherdomain.com
250 <POSTMASTER@mail.otherdomain.com>... Recipient ok
>>>DATA
354 Enter mail, end with "." on a line by itself
From: Postmaster <POSTMASTER@mail.domain.com>
To: Postmaster <POSTMASTER@mail.otherdomain.com>
Subject: This is a test message

Postmaster,

      This is a test message.

The important rule is to make sure that there is a blank line after the last header, but before the first line of the e-mail message.  Secondly, if you forget a 'TO:' header, Sendmail and other mail transport agents (MTAs) may add an 'Apparently-To:' header based on the 'RCPT TO:' information.

One other note -- I remember reading somewhere that MTAs are allowed to change the case of mail headers so that 'Subject:' my be transformed into 'SUBJECT:' or 'subject:'.  For a while, Sendmail would capitalize the first letter of every word in a header so that 'x-mozilla-status:' became 'X-Mozilla-Status:'.
