I tend to warn against blanket block of whole IP ranges or whole domains myself, but I know some actors do just that. I have myself been less than pleased with Google's mail handling at times, but for a domain or IP range block to have been put in place, there would have had to have been a fairly major incident (possibly of the misconfiguration kind) to trigger those extreme measures. The main irritant here is that the big G seems to not ever actually answer messages. You only know they notice you fixed the problem by your mail actually reaching Google hosted destinations after their dis-grace period expires. > I am not affiliated with the city of Kuopio or their ICT partner > Istekki myself, I'm just watching this as a curious onlooker. > > Based on what I see in spamtraps, "sending email from Microsoft environments" > isn't happening. 100% of the (very small amount of) email genuinely sent > from the City of Kuopio is sent from a dedicated server managed by Istekki > which is not a Microsoft environment. Routing outgoing through a smarthost that is properly identified as such in the various SMTP related TLAs (and others) would be my recommendation too, at least until there are indications that the IP or domain reputation is sufficiently on the mend. - Peter -- Peter N.
