google block residential ips. even with a specific message. not based on reputation, based on ip block. I am well aware that smtp have been abused for decades now, I run my own mail server and have no problem sending to google outlook etc. my point was only regarding blocking residential ip. google definitely does that (on top of many isp's) and it is not part of how the smtp protocol works. no conspiracy here.
- sbuk 5y agoYes, because of low/no reputation. It's a feature, not a bug.
- peppermint_tea 5y agono, because they belong to a residential ip block. it is easy to test... and the error message is without ambiguity.
- peppermint_tea 5y agojust testing now, not every residential ip it seems (I moved country and now my email go through without the message : ...belongs to a residential ip...)
