Smtp mail sending requirements?

I have recently found out that a lot of my emails have not been getting to their intended targets. I recently had turned off my MTA (Postfix). I had never thought about it before because I thought that the email client took care of the SMTP.

 

Which way does this really work? Can SMTP emails be sent with no MTA running?

I found this really helpful link: here

 

in short, you need an MTA to send mail, since SMTP is just a protocol...the program which makes the connection is the MTA agent/daemon. Email clients are well, just clients, and without a server (the MTA) clients are useless.
