TwitterHello,
First of all thanks for reading this and trtry to help me.
I have a problem. Al mail sent from my clients to gmail and hotmail ends in spam folder. Not from one server, several ones.
SPF is correctly configurated, DKIM also. Gmail said this not me:
But mail ends in the spamfolder. I have servers With Debian 9 and Debian 8. Obsidian 18.0.29 (and the new feature of "Fix incorrectly set sender for outgoing mail" activated) 18.0.28 even 18.0.24 all with the same problem.
IPs are not blacklisted, reputation of the IPs is normal or good, all IPs are with the SDNS and JUNK program of Microsoft... I did all that I can did.
If I check the mails headers in mxtoolbox the only problem I have is:
I read all the info or plesk articles but it doesn´t help. It is not clear why this error and how to fix it.
Also in MXtoolbox headers analyzer I can see this when mail is sent from webmail:
I don´t know why 6:: is shown and server.localdomain is shown. But if the mail is sent via Thunderbird for example the "Body Hash Did Not Verify" error is there. And mail arrives to spam also.
If anyone can help me it will be much apreciated.
Thank you
