Note the list arguments about silently swallowing emails and then think why these arguments are relevant (hint: swallowing email on MUA level).

It is clear to me from the entire Sender-ID development from its roots in the ASRG, as well as the information I heard directly from Microsoft employees on the subject, is that the Sender-ID standard is intended to be deployed on the MUA level by Microsoft. Of course, they are free to correct me.

But SPF classic requires *zero* changes to the MUA, its just the MTA that is 
enhanced.

This is especially true if one of the goals is to preserve MTA to MUA bandwidth 
nad/or clutter of
bad emails at MUA.

Why will that help deployment?
The latest surveys state that MS SMTP servers have less than 10%
market share.
I'd say having sendmail + qmail + postfix + exim will help more than
having MS on board for whatever solution.


 I made this point a while ago on the spf-discuss list.

While it would

be nice to have Microsoft on board, they do *not* have the

lion's share

of the installed base of internet facing SMTP servers.  That's where
most of implementation of these standards will take place.
 I would be quite disappointing if this draft was pushed

through with

the current patent license because someone thought 'we need

Microsoft'.

Even if we did, shunning this license does not have to mean pushing
Microsoft out, so to me, it would make no sense to push this through
just because someone thinks we need Microsoft.


We had this argument in the ASRG as well until some pointed
out that the
PRA algorithm works in MUA. The market share on Microsoft
MUAs is over 70%.
