False.

You're talking about the fact that Postfix has only a small fraction of
the SMTP servers in ORDB. qmail, for example, has nearly 8 times more.

You're ignoring the fact that Postfix has only a small fraction of the
SMTP servers on the Internet. qmail, for example, has 11 times more.

Dividing these two numbers produces a much more sensible measurement of
the misconfiguration frequency for common SMTP servers:

   178 Microsoft products
   128 IMail
    52 Sendmail
    23 Exim
    18 NTMail
    15 Postfix
    10 qmail
     8 smap
