Protocols Used for Access to

Neda PCCS

This section describes how various Neda Messaging Services can be accessed. Access

mechanisms described in this section reﬂect the current state. This document will be

updated as these access mechanisms are updated.

Neda Messaging is built around openness. We emphasize and promote ”Main-

stream Networking”. Openness is achieved through use of publicly available standards.

Simple Mail Transfer Protocol (SMTP) [RFC-821], the native Internet Mail proto-

col, is used as the backbone to interconnect most e-mail environments in the Internet.

The samething holds true of Neda Messaging Services.

11.1 Messaging Protocols

The following lists the pertinent Messaging RFCs:

• Internet E-Mail Format (RFCs 822, 1049)

• Addressing and Routing (RFCs 920, 974, 1034, 1035)

• Transfer protocols (RFCs 821, 976)

• Enhancements to the basic service (RFCs 1341, 1342, 1421, 1422, 1423, 1424)

• Interoperability with X.400 (RFC 1327)

Figure 11.1 illustrates this.
