It has been a long time but GMail/Google is again boring enforcing some new obscures rules. Since few days all emails sent from my domain setup in Virtualmin since a long time bounces back with that error:
<xxxxx@gmail.com>: host gmail-smtp-in.l.google.com[2a00:1450:4001:c21::1a]
said: 550-5.7.1 [2001:1600:1ff:b:ec4:7aff:fe6e:f698 19] Gmail has
detected that 550-5.7.1 this message is likely suspicious due to the very
low reputation of 550-5.7.1 the sending domain. To best protect our users
from spam, the message 550-5.7.1 has been blocked. For more information, go

If I check the sending domain in Postmaster Tools everything is green so very confused what’s the problem here. Only messages I could find on Internet relates at that problem but 2/3 years ago.
Anyone else encountering the issue ? or found how to go around it ?
We only block some emails that look like spam, not all of them. An email might be blocked if it contains words that look like spam or if the sender has a history of sending spam. If you’re an organization or company that sends emails to personal Gmail accounts (@gmail.com or @googlemail.com), review the Email sender guidelines.
As they always did these bullsh*t american IT companies but still I’d like to find a solution at the problem as emails that generated that answer had no reason to be considered as spam (business emails).
Have you wondered where we would all be without these “bullsh*t” American IT companies?
Anyway, if you’d like, send me the domain name by DM, and I can check it. Otherwise, verify that at least SPF, DKIM and reverse DNS are configured correctly.
Sounds like whoever had the IP before you did alot of spamming and the IP has got the “bad reputation”. So look for a Bad Reputation checker. Google it you should find a few around.
I had a Bad Reputation on a IP and I could not remove the bad reputation. My VPS provider have Reserved IP’s that you add and remove at very little price, I went through a few until I found a clean one and then attached it to my server.
If you use a VPS provider you may have this option.
This is a Bad Reputation checker I found.
Thanks but no as I have that class of IP since quite few years so they don’t have a problem of reputation
Problem looks to be quite random on Google side as I tried to send an email from the domain concerned to my gmail account and first time it arrived at gmail without problems although listed as spam, I told gmail it’s not spam and now if I try again to send an other email I have that same non sense bad reputation message (while the postmaster tool of Google states everything is good for that domain…)
When you say email is for business, is it to existing customers or are you sending email to businesses promoting your products or services, the latter will probably be construed as unsolicited hence spam by Google, better people find you on the web and contact you for your products and services.
It’s just regular emails, not mass mailings or anything and it looks from outside to be quite random. I have some emails that are properly delivered at gmail adresses and some other boucing (while sent from same Thunderbird instance from same computer…). It’s always emails to gmail free accounts.
I always checked the IP I was given on online.net, scaleway etc on blockIists, I frequently complained and got one eventually that was apparently clean, considering the amount they reuse after porn, spam and warez sites they have been used for. I remember chatting with a Hetzner engineer about IP’s and asking about a clean one, the response was there is no such thing as a clean IP. Personally I think that as an individual we should be given an IP address at birth so to speak, like a national insurance number etc, exlusive to us personally, cherished, protected, everyone should have a personal website that they can develop for their life ahead.
Yep but still don’t understand why Google decided to block that IP while I have that class exclusively for me since more than 4 years now and I run only hosting services and no spam, intensive mailers or other nasty activities…
No idea unhappy as by default it goes through IPv6 if avalaible and google supports IPv6 so all traffic goes with IPv6.
Annoying when you think it was the likes of these free email accounts like Google, Yahoo and especially Hotmail that basically fueled the spam problem.
Yep and they still continue to host most of spam with OVH also in France !
Well here it can’t happen as it’s some IPs attributed by RIPE and it’s difficult now to ignore IPv6 as it’s large part of traffic at least here in Europe.
@vincen, if you’re sure you have set up everything as it should (DNS, rDNS, DKIM, SPF, message headers), your only hope is to convey the problem to the recipient and encourage them to complain to their email service provider.
This is the proper way.
It is totally unreasonable that a recipient’s mail service provider would still block you after you satisfying all the standard measures.
And it is unreasonable that they request non-standard measures and conditions “just because they’re too big”. Their users should complain.
Back in the day when businesses self-hosted their mail, you could call the admin on the other side and discuss how to solve the deliverability issue. Good luck with finding a human in the “big tech” ones.
Again, if you’ve satisfied all the standard measures, it is not your fault any more. Your recipients must understand this.
@vincen Your server’s PTR is your ISP’s generic auto-generated hostname, not your domain. Ask your ISP to set it to your mail hostname to match your A record and HELO, and check Spamhaus PBL.
@Ilia sorry but you made a mistake there the IP you shared me is the one of the SMTP client (Thunderbird that sends the email to my SMTP server) not the one of my Virtualmin/mail server My mail server for sure has a proper PTR both in v4/v6.
I went around the problem as in all matters it was planned to move that domain to an other hoster
but still I’d like to find a solution at the problem as emails that generated that answer had no reason to be considered as spam (business emails).
