Requests for Comments

Requests for Comments (RFCs) are documents issued by the Internet Engineering Task Force (IETF) at the Network Information Center (NIC). Each such document defines an aspect of protocol surrounding the Internet. We have listed the RFCs that pertain to sendmail in reverse numeric order—that is, with the most recent documents cited first. Note that many of these are of interest only to historians. RFCs are available via the Web and anonymous FTP from: http://www.ietf.org.
