Right. Anyone can open a bug, but we enthusiatically close that are invalid.

Right. That's why there need to be alternatives to making the mail look less 
spammish. No one is required to persuade bank execs to behave differently...

Right.

That's a rabbithole of a different nature.
My point in mentioning the KAM channel was as an example of a local choice 
outside of the default deployment which has a radical effect on FPs. Akin to 
lowering the threshold to 3.0

(FWIW: I think the KAM rules are fine if, like PCCC, you have a staff of 
antispam experts and a mature package of customer-facing and staff-facing tools 
and processes to minimize and mitigate FPs. I use them personally, but I have a 
robust warren of ways for mail to get around SA analysis... )

Yes, I don't foresee ever seriously considering the addition of any 
marketing-oriented ESP per se to the default welcomelist. They all sometimes 
send spam.

The Microsoft case is an example. The entry I removed matched any subdomain of 
microsoft.com, triggered by spam from an address at email.microsoft.com which 
came to me from a Marketo IP address. Marketo sends a LOT of spam. Marketo 
generally has no listing of its own.
