Microsft outlook and Google Gmail hosts most spammers on the Planet Earth.
Nah, the worst offenders are OVH and Contabo, followed by digital sewer, then gmail :)
If you make spf -all for gmail that helps a lot. However there are still quite a few 'my family member is so good with computers integrators' that tell their clients they it is ok to use an ip that does not even match spf.
