SMTP: What Is It?

SMTP, short for Simple Mail Transfer Protocol, is the core protocol for sending email over the Internet, from the sender to the SMTP server and between email servers. Though perhaps not as simple as its name suggests, this robust text-based protocol is the primary transmission medium of Internet mail and forms the backbone of the Internet's messaging system, taking care of transferring mail from user to user across TCP/IP networks. Indeed, SMTP happens to be the key component of the TCP/IP electronic mail system, and the sole part of the system that does not utilize SMTP for the final retrieval of the delivered email by recipient (this is performed by a retrieval protocol).

Email servers and mail transfer agents (MTA) utilize SMTP to both send and receive mail. But as the message completes the route from the initial outgoing email server to the destination server, it is retrieved by the recipient's email client via one of the standard mail retrieval protocols (POP or IMAP) that are complementary to SMTP (which handles only outgoing and not incoming email).

Additionally, SMTP is employed to submit email from an email client application to an email server for further relaying. For this reason, both the outgoing (SMTP) server and the incoming (POP or IMAP) server generally need to be specified in the configuration of an email application. Emails clients (a particular kind of user agent) are normally configured to submit all email to a single MTA, specified in the configuration parameter "outgoing mail server."Under SMTP, the mail sender "talks" to the mail receiver via SMTP commands (there are over a dozen of them, each of which contains four letters) and transfers requisite data over the Transmission Control Protocol (TCP) layer. SMTP relay begins by specifying the sender, then the recipient(s) of an email message, and once their existence has been verified, the message body itself is transferred. (The availability of an SMTP connection may be tested easily by telnetting to port 25 of a remote SMTP server.)

About SPF and DKIM

SPF records are also DNS records that some receiving mail hosts use to verify the authenticity of mail. The SPF record provides a list of addresses (IPs and DNS names) that are allowed to send mail on behalf of a particular domain. SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are two methods to help indentify email which is likely not SPAM. Both SPF and DKIM attempt to provide information to receiving SMTP servers about whether or not a particular email message is authentic. SPFv1 uses a very simple approach where a domain’s DNS server provides a root level TXT record that supplies information about SMTP mail servers that are permitted to originate domain email. Domain Keys is a type of email verification system using public key cryptography. DKIM uses a more complex digital signature on each message (information about which is stored in a sub-domain in domains DNS containing self-signed keys).
