when I check the message in my mail inbox
maybe because I am not logged in

When sending a message to an SMTP server, the first part of the conversation is what is called the "SMTP Envelope"; basically identity stuff to the server. The commands "HELO (or EHLO), MAIL FROM: and RCPT TO: are all part of the envelope.
Everything after the DATA command is the actual e-mail message. Most e-mail clients look here for the sender data, TO: and CC: information, Subject line, and the date/time of the message (although some clients look at the mail headers for the date/time). After you issue the DATA command, you should send lines similar to this:
Date: Sat, 22 Dec 2012 23:16:00 -0500From: John Doe <john.doe@example.com>To: Jane Doe <jane.Doe@example.com>CC: Little Timmy Doe <tim.doe@example.comSubject: Holiday Shopping
Keep in mind that what you put here is what the recipient's mail program uses to separate TO: addresses and CC: addresses. When send mail to the server, both TO: and CC: addresses are part of the RCPT TO line.
Hope this helps.

yes,
but I can only get to data
if the
mail from:
and
recpt to:
are the same
I want to send to another address, so I must log on to my email
A Bas64 SMTP login cannot effectively be done manually. It requires that the password be encoded. Wikipedia actually has a fair explanation of base64 encoding:
because this retrys a previous email, how can I write a new email

Retr 1 up is a a pop mechanism to read emails you received.
You have to use smtp to send email.
Base64 is needed to encode the username/password for authentication.
You can test you smtp telnet by sending an email to yourself, a server that handles incoming emails for mydomain.com will not require authentication from anyone when a message recipient is user@mydomain.com
It applies to how you may have to enter the username & password during SMTP authentication in order to relay mail (send mail to a domain other than yours). If you can get the POP3 login example to work, that may be all you need, because some SMTP servers are configured to allow relaying after a successful POP3 login from that IP address.
Login via POP3, then immediately logout. Then try a simple SMTP session, with a RCPT TO: address that is not in your domain, and see if it goes out.
