[Asrg] Default SPF Enablement?

So why don't the major MTA distros do this?

man forward
Claus,

Here is the result:

C:\Documents and Settings\admin>man forward
'man' is not recognized as an internal or external command,
operable program or batch file.

and

[root(_at_)mooncake ~] man forward
No manual entry for forward

Seriously, if I interpret your two words accurately, you
are saying that SPF breaks forwarding (and aliasing)
to foreign e-mail addresses. But  does it?

What should the RCPT FROM be when an e-mail
is forwarded?  The original foreign sender or the local user
of the forward database?  In other words, if I forward e-mail,
shouldn't the envelope and headers change to reflect that I
forwarded?  An MTA that does this appears to be
SPF-friendly.  Actually, it appears that an MTA called
"qmail" does this, judging by the top results in a
google search for "forward man page".  The sendmail
version seems more capable, but the example uses a
pipe to the "vacation" program, use of which I
understand to be bad etiquette. forward under sendmail also states
nothing about modifications of the envelope and
headers; therefore I must assume that sendmail keeps
them intact.  But why?  I'm trying to understand
history, in an effort not to repeat it.

Cheers,
Douglas Campbell
