No! The "mail" command is an MUA.

So is Postfix. >From a 30,000 foor view... 1) You write an e-mail using an MUA. 2) When you select the "send" button, the MUA submits this e-mail to an MTA. Sendmail in this case. 3) The MTA then delivers this e-mail to another MTA (yahoo.com using your example). 4) You then use yahoo's MUA (web interface) to view this e-mail. 5) Now you select the reply button using yahoo's MUA. 6) When you select send, yahoo's MUA submits this e-mail to yahoo's MTA for delivery back to you. 7) Yahoo's MTA opens a connection to your MTA (sendmail). 8) Sendmail receives this e-mail from yahoo and (if the mailbox is local) hands this e-mail off to the defined LDA (procmail), which stores it in your mailbox. Sendmail is now out of the picture and waiting for another connection. 9) Using an MUA of your choice, you can now view your reply.
