Duplicates message in pop3

Question

When im doing my lab project ("pop3 mail client") im find something mystery in server answer- messages duplicates two times, for example:

S: Subject: Test 1
S: From: *** *** <***@gmail.com>
S: To: ***@mail.ru
S: Content-Type: multipart/alternative; boundary=***
S: X-Spam: Not detected
S: X-Mras: Ok
S: X-Mru-Authenticated-Sender: ***@gmail.com
S: 
S: --04***********************49
S: Content-Type: text/plain; charset=ISO-8859-1
S: 
S: Hello
S: 
S: --04***********************49
S: Content-Type: text/html; charset=ISO-8859-1
S: 
S: Hello
S: 
S: --047d7b10c7979b168d04d00bd749--
S: 
S: .

Is this normal? Thank you very much.

Not particularly as far as I know, but we'd have to see your code to say more. — Ben Barden, Dec 04 '12 at 19:45
I suggest you search the web for that Content-Type value "multipart/alternative" — Ian Roberts, Dec 04 '12 at 19:46

This is normal. Note the message's type: multipart/alternative.

The multipart/alternative MIME type contains multiple bodies, each of which is typically the message body in some other format. In this case, the sender's mail client included both HTML and plain text versions of the message body. The receiver would select the most appropriate format and display that version of the message.
