Status of this document:

This FSC suggests a proposed protocol for the FidoNet(r) community,

and requests discussion and suggestions for improvements.

Distribution of this document is unlimited.

|
Purpose
|
|
|
|
To explain and document the existing usage of the ^aFLAGS field used
|
|
by many software packages, including FrontDoor, TosScan, and
|
|
D'Bridge. And to inform software authors of its proper usage.
|
|
|
|
|
|
Prologue
|
|
|
|
One of the problems with the FTS-1 (stored) message format is its
|
|
limitations in regards to message attributes. Several bits are used
|
|
(reserved) by SEAdog, another by several packers and editors - even
|
|
though most mailer authors don't support them, they remain. One
|
|
reason would be backward compatibility with older software.
|
|
|
|
Unfortunately, this presents a problem for software authors that
|
|
would like to pass extended message attributes for use and handling
|
|
by other software.
|
|
|
|
Some software packages have been using an alternate method called
|
|
"FLAGS" which is 7-bit ASCII placed behind <SOH>FLAGS somewhere near
|
|
the beginning of a message. The various flags will now be described.
|
|
|
|
|
|
Flags
|
|
|
|
The FLAGS string should be placed somewhere near the beginning of
|
|
the message text, and is preceeded by a <SOH> (^a) character. There
|
|
is no need to support all or any of the below mentioned flags.
|
|
|
|
If flags are stripped when a message passes through a system, all
|
|
relevant and correct FTS-1 status bits should be updated to indicate
|
|
the original contents of the FLAGS field.

Notes
|
|
|
|
Xmail is related to the ARCmail 0.60 standard as adopted by the FTSC.
|
|
The exception is that any type of compression method may be used and
|
|
the naming convention isn't necessarily limited to that of the
|
|
ARCmail 0.60 standard.
