Can SMTP be used for receiving message?
I have heard that it can be, if yes than how?
please illustrate me with example.

what are you trying to accomplish? smtp is the protocal that is used to send mail, pop/imap are the protocals used to recieve mail...

smtp is for a server to send email to another server... eg: servera has email for serverb... servera connects to serverb and gives it the mail... it would look something like this:

220 winbots.org ESMTP
HELO SERVERA
250 winbots.org
MAIL FROM: Cobi@SERVERA
250 ok
RCPT TO: Cobi@winbots.org
250 ok
DATA
354 go ahead
SUBJECT: Hey
testing
testing
testing
.
250 ok 1117608131 qp 24791
QUIT
221 winbots.org


ServerB (winbots.org)
ServerA

Yes you are right BUT B U T ..........


If server send email to serverB its like this ..........

serverA -->> SMTP >>> ServerB(mailQ) (here pop works for serverb)-->>POP-->>email Account

Got it ???
