SMTP

SMTP is an easy protocol that is text-based and is used when a message needs to be sent to more than one recipient (once verification has occurred), as soon as the verification is done the message will then be sent. To test an SMTP server you can use a telnet program. TCP 25 is used by SMTP. A DNS record will be used in order to find out the SMTP server for a particular domain name.
