This morning I took a look at the spam I received overnight.

@stefano This is very close to what I experience too. Looking at the spam that reaches an inbox here, it is very rare to find any that did not come from MSFT or GOOG infrastructure.

[stefano@mastodon.bsd.cafe]

@pitrh I think that our antispam engines are good enough to filter most of the spam. But a "legit" mail coming from a MSFT or GOOG infrastructure is much more complicated to spot.

[pitrh@mastodon.social]

@stefano also GOOG has some odd ideas about what it considers spam.

I had a problem reaching GOOG hosted domains from my regular address -- my messages consistently went to the spam folder or just disappeared.

Then it turned out that the problem was my .signature had a reference to blogspot.com -- a GOOG hosted domain, which for some reason had made it onto one of the spamhaus badness lists, leading to a reject when trying to post to a mailing list for that reason.

[pitrh@mastodon.social]

@stefano so we had GOOG content filtering rejecting mail over a reference to a GOOG hosted service.

I have since sanitized my .signature, which seems to help, but I still randomly get my messages to GOOG hosted domain spamboxed.

Never any reason given or response to queries, of course.

@pitrh they will never reply, as their intention is to convince people that "you need their services to ensure high reliability in delivery".
Some of my customers tried and they even received more spam (or some legit mails in spam). After one year, most of them decided to go back to their self hosted servers.

@pitrh @stefano even spammers don’t know how to setup an SMTP server these days 🤭

@joel @pitrh @stefano

Vibe spamming is in.

[xinqu@mastodon.bsd.cafe]

@stefano I simply block everything from gmail, except a handful of whitelisted addresses of people I know.

This is not a solution if you are running a mailserver for more users than just your family, of course. But works very well for me.

@stefano looking at my Spam, Amazon/AWS seems to also be used a lot to relay Spam.

[stefano@mastodon.bsd.cafe]

@seiz yes, they do!
