What is an SMTP server?

An SMTP (Simple Mail Transfer Protocol) server is an application that’s primary purpose is to send, receive, and/or relay outgoing mail between email senders and receivers.

An SMTP server will have an address (or addresses) that can be set by the mail client or application that you are using, and is generally formatted as (For example, Gmail’s SMTP server address is You can generally find your SMTP server address in email SMTPBD send your all information to your registered email.)

When you send an email, the SMTP server processes your email, decides which server to send the message to, and relays the message to that server. The recipient’s inbox service provider, such as Gmail or AOL then downloads the message and places it in the recipient’s inbox.

SMTP server Is the same as a normal server?

Technically, yes. Like most servers, the SMTP server processes data to send to another server, but it has the very specific purpose of processing data related to the sending, receiving, and relaying of email. An SMTP server is also not necessarily on a machine. It is an application that is constantly running in anticipation of sending new mail.

Why are SMTP servers important?

Without an SMTP server, your email wouldn’t make it to its destination. Once you hit “send,” your email transforms into a string of code that is then sent to the SMTP server. The SMTP server is able to process that code and pass on the message. If the SMTP server wasn’t there to process the message, it would be lost in translation.

Additionally, the SMTP server verifies that the outgoing email is from an active account, acting as the first safeguard in protecting your inbox from illegitimate email. It also will send the email back to the sender if it can’t be delivered. This informs the sender that they have the wrong email address or that their email is being blocked by the receiving server.

  2. Your mail client has a conversation with our server, first verifying that the username and password used for authentication correspond to an active account, then relaying the message information, such as sender address, recipient, and message content.
  3. Our server takes the message information we gathered from your request and then repeats the conversation process in Step 2 with the recipient’s mail server.
  4. The recipient’s mail server checks the sending address, recipient address (to ensure they are a valid recipient), and message content. It checks the sending domain for any potential DNS issues, such as invalid DKIM and SPF signatures. As long as there are no issues, the recipient’s mail server will use the protocols POP3 or IMAP to retrieve the email and deliver the message to its intended recipient.
