All mail to gmail reported as spam

alberto464

New Pleskian
The emails sent by the server are flagged as spam by gmail.
Simple text emails are flagged as spam and interface gmail reports:
Because its contents are typical of spam messages
But in reality they are not at all spam. Doing tests with mail-tester.com get a score of 10/10, so much more than other servers where mail is accepted.

How can I fix?

Ciao tra poco escono i risultati, prova a controllare grazie

For security reasons I had to cover the sensitive fields, with 151.xx.xx.xx I covered the ip of the server and various websites.
If someone can not find the solution I make him a monument. :)
 
Hello Alberto,

There are numerous related threads here with recommendations ..
Did you search the forums before posting?
 
I sincerely looked all similar post but it comes to SPF or dkim unauthenticated, in my case these two are authenticated and do not understand the problem. I thank those who manage to find the problem.
 
Have you checked your score on http://www.mail-tester.com/ ?

Also check if your server (sending) ip is on some sort of blacklist via http://mxtoolbox.com/blacklists.aspx

That might help you figure out what is wrong.

It might also just be because you sent a very short message, try sending a longer better formatted message with a greeting.

As written above, I use email-testers get a score of 10/10, the IP is not in any blacklists and if I send a longer message ends up in spam
 
Have you also tried sending it to a different gmail address? I think the only other option you have is talk to Gmail support team.
