(Which may be the machine that you are typing on, or might not.) In other words: you successfully sent mail, but Google rejected it because they think you are a spammer. One option is to relay mail through an email server that is generally considered trustworthy. Another is to build the reputation of the server you are using, but it seems likely that you have an IP connection from free.fr, and they are specifically advertising that you are a user and should not get a positive reputation. Mail is tricky these days. -dsr-

No. Google rejected it because of the reason stated above. I.e. MTA's IP does not have a valid PTR record. Not required by RFC per se, but is considered mandatory by some (included Google). > One option is to relay mail through an email server that is > generally considered trustworthy.

It's entirely because IPs without PTR records are more likely to be spammers than those who do. Specfically, because it's an indication that the person running the machine didn't set it up as a server, or doesn't know what they are doing. > > Another is to build the reputation of the server you are using, > > Won't do any good.

An error message included a link to support.google.com. Along with the other things it says: The sending IP must have a PTR record (i.e. a reverse DNS of the sending IP) and match the IP obtained via the forward DNS resolution of the hostname specified in the PTR record.

Because their server says so. Quoting from this very thread [1]
<<< 550-5.7.1 this message does not meet IPv6 sending guidelines regarding PTR
<<< 550-5.7.1 records and authentication. Please review
<<< 550-5.7.1 https://support.google.com/mail/?p=IPv6AuthError for more infor
And quoting from that Google link (eek, I clicked a Google link and
feel now... dirty):
- The sending IP must have a PTR record (i.e. a reverse DNS
of the sending IP) and match the IP obtained via the forward
DNS resolution of the hostname specified in the PTR record.
- The sending domain should pass either a SPF check or DKIM
check.
So you need a PTR (for reverse name resolution) AND (SPF OR DKIM)
(so yeah, PTR alone ain't enough).

Quoting from this very thread [1] This is like answering "why do you think mother married father?" with "Because the marriage certificate is hanging on the wall." Did you and Reco both translate the question as a request for evidence? I would think that my next statement, which you both decided to drop from quoting, would correct that. -dsr-

I would think that my next statement, which you both > decided to drop from quoting, would correct that. > A mail server admin's choice of anti-spam measures can be fairly arbitrary. My mail server does what it does 'because I say so'. I think that was the point being made. PTR records are nowhere near as useful as they used to be. Many domestic users are given PTR records now, even if they are just some derivative of the IP address, and many companies using email simply outsource it. Some email services are run by people who don't know what they are doing, so some legitimate business email arrives from addresses without a complementary PTR-A record pair. -- Joe

Or is trying to run the server on an IP without a (useful) PTR record, e.g. a "personal" ISP account. This requirement mitigates somewhat the spam problem, at the expense of making it much harder/costlier for individuals to run their own mail server.

You can and you can't. In theory you can. In practice, the email giants -- GMail, Outlook.com, and a few others -- demand certain things that make it very difficult to deliver mail to them if you've just got a home net connection. Meanwhile, traffic to other domains might go through easily. -dsr-

I, for one, do. I run my own mail server. But yes, you gotta invest some elbow grease. Cheers -- tomás

You can in the UK. You need to use an ISP who will provide a fixed IP address (most do, though BT will charge an extra tenner a month for the privilege) and who takes care to stay off email blacklists. I stayed with Demon long after it was a competent ISP because I had no trouble sending email. I've been with Plusnet for nearly two years, and have had no problems. But yes, sooner or later, Internet regulation will reach the point where governments will permit only licensed organisations to send email, and a licence will not be cheap. -- Joe

Certain ISPs (primarily those focusing on home customers, and especially those providing dynamic IP addresses) will block outbound connections to port 25 (smtp) by their clients. If your connection comes from such a provider, then, yes, you do have to pass your mail through their mail server, because their firewalls will prevent you from directly connecting to any other mail servers. But if you're not in such a situation, then you absolutely can run your own mail server, although there are hoops you need to jump through to avoid being mistaken for a spammer. Having a static IP in a non-blacklisted subnet and properly-configured DNS pointing back to that IP address are, in my experience, the primary factors. I don't think I've ever needed to do more than that for my own personal mail server, which I've been running since the summer of 2000, and it's been connected on at least 4-5 different ISPs over that time, including both residential and commercial providers. If you want to send mail claiming to originate from other servers, then *that's* where it gets tricky and cumbersome, because you need to properly handle SPF and DKIM restrictions, which you may not have any direct control over. I occasionally have to deal with this at work, and it's never a pleasant experience. -- Dave Sherohman

I don't mail from my home machines. Instead I've got a virtual host "out there" (in my case it's a slice of a "real host" I share with a couple of friends). But I do know of people who do it from home. Cheers -- t

Once you have a server running 24/7, there are all sorts of things you can find for it to do. I'm considering using something like a Raspberry Pi when the current HP Microserver dies, but I'm not sure it will be a lot cheaper to run, given that it will need external hard drives and an external Ethernet port. -- Joe

Depending on why you feel you'd need an external Ethernet port, the Pi 4 might address that issue for you (it's no longer wired over the USB bus) I'm reminded that I have never properly measured the power consumption of my always-on NAS: I built it to be low power and I've connected it via a watt-meter but I haven't ever read the manual for how to use the meter (or looked at its display). -- Jonathan Dowland https://jmtd.net Please do not CC me, I'm subscribed to the list.
