To actually send a message, you can use a combination of the HELO, MAIL, RCPT, and QUIT commands. HELO introduces the hostname that you are connecting from:
HELO client.companyB.com 250 server.companyB.com Hello client.companyB.com [192.68.232.45], pleased to meet you
Next, you need to specify a sender by using the MAIL command:
MAIL FROM: <pwatters@companyB.com> 250 <pwatters@companyB.com>... Sender ok
You should then specify a recipient for the mail by using the RCPT command:
RCPT TO: <postmaster@server.companyB.com> 250 <postmaster@server.companyB.com>... Recipient ok
After you transmit the sender and recipient information, it s time to actually send the body of the message by using the DATA command:
DATA 354 Enter mail, end with "." on a line by itself Hello, My mail client is not working so I had to send this message manually can you help Thanks. . 250 KAA11543 Message accepted for delivery
After the message has been accepted for delivery, you can then terminate the session by using the QUIT command:
QUIT 221 server.company.com closing connection Connection closed by foreign host.
The message has now been successfully transmitted.
Mail Headers
Mail headers are useful in understanding how mail is transferred. For example, if a message is sent from a mail client on the local server to another user on the local server, the headers are easy to interpret:
From pwatters@companyA.com Fri Feb 18 13:31 EST 2000 Received: (from pwatters@localhost) by mail.companyA.com (8.9.1a/8.9.1) id NAA17837 for pwatters; Fri, 18 Feb 2000 13:31:34 +1100 (EST) Date: Fri, 18 Feb 2000 13:31:34 +1100 (EST)
Part VI:
Services, Directories, and Applications
From: WATTERS Paul Andrew <pwatters@companyA.com> Message-Id: <200002180231.NAA17837@mail.companyA.com> To: pwatters@companyA.com Subject: Testing Local Delivery Content-Type: text Content-Length: 5 This is a test of local delivery.
These headers can be interpreted thus: the local user pwatters@localhost sent the remote user pwatters@companyA.com a five-line message, encoded as text, on the subject of Testing Local Delivery. The message was serviced by the sendmail MTA version 8.12.10, and had an ID of 200002180231.NAA17837@mail.CompanyA.com. If mail is forwarded from another host, then the headers become more complicated, but follow the same general principles.
Using Multipurpose Internet Mail Extensions
As you saw in the previous example concerning mail headers, there was a header that specified the content type (Content-Type), which was text in the example but could have conceivably been any kind of digital medium, thanks to MIME, as proposed in RFC 2045. MIME is very useful for sending multimedia files through e-mail; it eliminates the worry about the specifics of encoding. Since many multimedia files are binary, and e-mail message bodies are transmitted as text, MIME encodes the files as text and sends them as normal messages. In addition, MIME supports the notion of multipart messages that is, a single e-mail message may contain more than one encoded file. This is very useful for sending a number of documents to another user: it is not necessary to overburden sendmail by sending a new message for each document (recall that sendmail processes e-mail messages one at a time). MIME also provides support for languages that are encoded in ASCII but that need to be displayed in another script (e.g., Japanese kanji). MIME defines how a Content-Type header can be used to specify a particular character set or other nontextual data type for an e-mail message. For example, the e-mail header
