Hello Peter,
Thank you for this article.
Do you know why, and particularly Microsoft, use very random IPs to send mails.
In that way, they make greylisting not as reliable as it should be. We could
all use greylisting if google or microsoft would use the same 4 or 5 IPs to
retry sending the mails.
Google and Microsoft don't help to fight against spam.

A final followup on this issue - I wrote a (relatively) short piece on
greylisting vs domains with multiple outbound SMTP servers, which
includes the little script I use to create a nospamd from a list of
domains, of course by feeding to 'smtpctl spf walk'.
You can find the article at

- TL;DR: don't download *my* nospamd, use smtpctl to generate your own :)
All the best,
Peter
