SMTP in full action

All functions that take place across the SMTP server are in the form of transactions. The SMTP begins with identifying the message sender, ascertaining recipients and finally ends with reaching the message to a desired destination. You can go through a detailed version of how SMTP servers work. Here take a look at it:

  • While connecting with the port 25, the sender is required to wait till the entire connection is accepted by the receiver. The transaction is also referred as Handshake.
  • After establishing connection between two servers the individual is free to set in the address for answering the mail message. Any error occurring during the process is to be reported to the desired address.
  • After setting the recipient’s address, the details of the address are incorporated.
  • After the address is set the message is sent with the help of the software system allotted for SMTP usage. If the mail reaches the desired address, the server sends an Okay code just to confirm that the transaction has taken place successfully.

You must know the fact that all details and data sent across the SMTP server are disposable. If you don’t close the transaction you may lose details of the transaction, as the server may fail to record them or store them unless you have taken the proper action. You have to ensure that the connection is closed appropriately.
