PMDF System Manager's Guide

This group of keywords controls what types of addresses the channel supports. A distinction is made between the addresses used in the transport layer (the message envelope) and those used in message headers.

822 (sourceroute)

Source route envelope addresses. This channel supports full RFC 822 format envelope addressing conventions including source routes. The keyword sourceroute is also available as a synonym for 822. This is the default if no other envelope address type keyword is specified.

733 (percents)

Percent sign envelope addresses. This channel supports full RFC 822 format envelope addressing with the exception of source routes; source routes should be rewritten using percent sign conventions instead. This keyword is also used in conjunction with DECnet MAIL-11 channels to force truncation of domain-style names after the first period. The keyword percents is also available as a synonym for 733.

Note Use of 733 address conventions on an SMTP channel will result in these conventions being carried over to the transport layer addresses in the SMTP envelope. This may violate RFC 821. Only use 733 address conventions when you are sure they are necessary.

uucp (bangstyle)

Bang-style envelope addresses. This channel uses addresses that conform to RFC 976 bang-style address conventions in the envelope (i.e., this is a UUCP channel). The keyword bangstyle is also available as a synonym for uucp.

header_822

Source route header addresses. This channel supports full RFC 822 format header addressing conventions including source routes. This is the default if no other header address type keyword is specified.

header_733

Percent sign header addresses. This channel supports RFC 822 format header addressing with the exception of source routes; source routes should be rewritten using percent sign conventions instead. Percent sign routing is used for PhoneNet channels which connect to systems running older versions of PMDF.

Note Use of 733 address conventions in message headers may violate RFC 822 and RFC 976. Only use this keyword if you are sure that the channel connects to a system that simply cannot deal with source route addresses.

header_uucp

UUCP or bang-style header addresses. The use of this keyword is not recommended. Such usage grossly violates RFC 976.
