 ### Submission - SMTP
 
 A MUA willing to send an email to a MTA needs to establish a connection with that server, then push data packets over a network that both the MUA (client) and the MTA (server) are connected to. The server implements the [SMTP](https://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol) protocol, which makes it capable of handling _Submission_.
