POP3 will receive emails and hold them for clients until they pick them up.

In short, IMAP stores messages on an email server, but this server can be accessed by the user to check and configure their emails.

Apart from the reply of the DATA command, the server can reply in a positive way 2xx reply codes or a negative way.

The negative responses can further be of two types; permanent 5xx codes or transient 4xx codes. If a server sends 'reject' then it is a permanent failure, and the client needs to send a bounce message to the respective server. On the other side, a ' drop' is a positive reply, in which the message is discarded instead of delivered. With time, it became a commonly used mail transfer agent. The content of the electronic mail consists of two parts, header, and body.

The former header is the subject of the message, while the body is the main content of the message. The sender and recipient address also comes under the header part. The header acts like an envelope holding the letter message in it. The two parts of an email address are the username of the recipient and the domain name. Let'stake, for example, mayank gmail. In case the domain name of the recipient's email address does not match with the sender's domain name, then the mail submission agent MSA will send the mail to the MTA.

Then, the MTA will search for the particular domain to relay the mail. The MX record contains the information regarding the domain name and IP address of the recipient. Once it locates, MTA establishes the connection with the exchange server and relays the message.

After receiving the incoming message, the exchange server delivers it to the Mail Delivery Agent. It stores the email and waits for the retrieval by the user. The user can access the MUA with the login and password. SMTPs are essential to send and receive emails. As an email marketer, you need to choose and configure the SMTP that suits your requirements.
