Well, your allowed to have your opionion .. no problems with that. 
And good for you then there are other MTA's you can try to configure.. 

Im using postfix for more that 10 years now, and im very happy with it. 
I get about 0.05% spam of all mails, and that 0.05% is catched by spamassassin, 
i dont see any spam at all. 
so yeah, if you dont know how to configure it, you get spam.. yes. 

Besides that. 
> 90% of global e-mail is SPAM. 
Yes ! correct, why? Because cappy IT guys configure there servers wrong. 
No postfix blame here imo. 

> 91% of targeted attacks start with e-mail.
See above..  

> What is Postfix's share of SPAM?
We dont care about the postfix "spam" share.. 
Have a look at microsoft exchange...  
94% !!! of exchange are open relays..  

Exim... 56% of exim servers are blacklisted. 

Novell GroupWize, 54% is in US. 

You see, useless stats without content. 


> Who makes Postfix?
A very nice dutch guy, living in the US..    :-) 


> What is wrong with Postfix?
Nothing, if you configure it right, and based on what your saying... 
(... not typing that)
