However, the use of an SMTP server has a clear advantage: if the recipient’s inbox server is busy or temporarily out of service and the e-mail can’t be delivered, the SMTP server responsible will automatically try to redeliver the e-mail at regular intervals. Then other network protocols - either IMAP or POP3 - download the electronic mail to the recipient's SMTP client.įrom a purely technical point of view, it would also be possible to send e-mails directly from the sender's SMTP client to that of the recipient. From there, the "Mail Delivery Agent" (MDA) sends it to the recipient's e-mail inbox. This is once again checked for spam by the MSA and/or the MTA and then transferred to the message storage area in the incoming mail server. Upon arrival at the destination SMTP server, the data packets are reassembled back into a complete e-mail. If not, the MTA splits it into small data packets to be forwarded to the destination SMTP server in the shortest and least congested route possible. If the recipient domain is connected to the same mail server as the sender, the e-mail will be delivered directly.
