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.

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.

[mailop] Google spurning the City of Kuopio, Finland

2023-01-24 Thread Atro Tossavainen via mailop
Hello world,

It was reported in Finnish news today https://yle.fi/a/74-20014495 that
the city of Kuopio (#8 largest in the country) is unable to send email
to addresses served by Google and that this would be expected to last
for about two weeks.

According to the comments in the article, the reason for the problems
was a problem on the email server of the city which caused the domain
name kuopio.fi to end up on a block list at Google.

The news article links to a press release from the city itself. It says
that for about a week, the city has had problems sending email from
Microsoft environments to Google accounts.

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.

If there is anything that should be reported back to the City of Kuopio
or their ICT partners, I'm happy to act as the local conduit. :-D
