simple and lightweight

Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks. SMTP was first defined by RFC 821 (1982, eventually declared STD 10),[1] and last updated by RFC 5321 (2008)[2] which includes the extended SMTP (ESMTP) additions, and is the protocol in widespread use today. SMTP uses TCP port 25. The protocol for new submissions (MSA) is effectively the same as SMTP, but it uses port 587 instead.

The Lightweight Directory Access Protocol (LDAPplay /ˈɛldæp/) is an application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.[1]
