What is an overview of SMTP service?
The ability to provide E-mail services to clients includes two critical functions: SMTP and POP3. Together, they provide the means for clients to send outgoing mail and check for new incoming mail, respectively. SMTP service is the side of e-mail that allows clients to send outgoing e-mail messages to any valid e-mail address. The SMTP server performs two basic but important functions. First, it verifies that anyone attempting to send outgoing e-mail through the SMTP server has the right to do so. Secondly, it sends the outgoing mail and if undeliverable, sends the message back to the sender. Think of the SMTP server in terms of your local post office. Just like snail mail, e-mail is routed in a similar fashion. While it does not cost a client 32 cents to send an e-mail, they must have permission to sent the outgoing e-mail message. The post office requires postage to send the message to the recipient. Hostwire requires that you have checked one of your POP3 accounts in the last 30 min
