• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue Mail send from webmail (Roundcube) goes to spam/junk

What are your results from:

Newsletters spam test by mail-tester.com

Secure Email



In the mail settings on one of your domains, are the following enabled?:

- SSL/TLS certificate for webmail
- Use DKIM spam protection system for outgoing mail

Lastly, did you contact Microsoft about this? In my case the IP adress i use was blacklisted, propably by the previous owner (not sure)
 
Exactly, 3 error.
- No DKIM-Signature header found
- There must be at least one aligned DKIM-Signature for the message to be considered aligned.
- UCEPROTECTL3 blacklist


How can I fix this?

Website & Domains > Hosting & DNS > DNS Settings

If you enabled DKIM signatures there should be a record with the following content: v=DKIM1; xxxxxxxxx
This record needs to be added to where you manage your DNS (GoDaddy i thought).

While doing this, please also check other records that are present in Plesk, but are missing from where you manage your DNS and also transfer them.
 
ok with the addition of the dkim.
Forgive me, regarding the removal of my ip in the - UCEPROTECTL3 blacklist
Do you think this is my problem or why is there a dns configuration error?
Many thanks for your support.
 
What is your score on mail-tester.com ?

Also, please contact Microsoft Deliverability support and open a ticket explaining the situation. In my case I was blacklisted, maybe this is also the same in your case.
