    Hello @Soufiane Abid,

    As all settings are correct, but emails still hit the Spam folder, please contact support of a corresponding mail service to remove your IP address from their blacklists:

    Hello @Daria

    I know the answer, because I have already had this kind of problem with other panels. Even Microsoft do not know given correct answer because I joined @Soufiane, I have the same thing is one for an anomaly, this falls in junk mail.

    Hello @Michel Renard,

    Thank you for sharing your user experience.

    Indeed, as Daria said, if the message passes SPF, DKIM and DMARC checks and the server is not blacklisted but mail still arrived to the junk folder then the issue is on the mail provider side.

    I would recommend you to review mail headers of the "junk" messages and sent them to mail provider technical support to investigate the reasons why it happened.

    Hello

    They just answered me and told me about JMRP and mail formatting, I use Outlook, the HTML format would be a big risk factor regarding the message sending?

    Are your lines, SPF and DMARC the right ones for sending a message?

    Dear Kuzma Ivanov

    My hosting running Plesk version 12.5.30 and my boss dont want to upgrade it, so i can not use DKIM system. Because of that, our emails send from my hosting sever always go into spam inbox. Could you tell me can i fix that issue without upgrade Plesk version, or if i upgrade to lastest version and enable DKIM how many percent our emails will go to our customer's inbox?

    Hello @Michel Renard,

    Thank you for the update.

    Let me address your questions one by one:
    > the HTML format would be a big risk factor regarding the message sending?
    No, there should be no risks in regards of it.

    > Are your lines, SPF and DMARC the right ones for sending a message?
    Yes, SPF and DMARC are the correct ones if it is setup properly.
    More information about SPF and DMARC configuration you may find here:

    > For my part is via the configuration it works great. I had to sign the agreement as Microsoft 'JMRP'.

    Glad to hear that everything works as expected now.

    Hello @Le Nguyen Kha,

    Thank you for your question.

    Until Plesk is not upgraded to the newer version, there is no way to use DKIM.
    So it is highly recommended to upgrade Plesk to the newer version using the following guide: How to upgrade Plesk to the next release

    > how many percent our emails will go to our customer's inbox?
    There is no statistics on this matter, however to ensure that everything is setup correctly and your IP address is not in the blacklists, please use the services like MXToolbox blacklist checker or Blacklist Check provided by WhatIsMyIPAddress.com.

    If everything is setup properly, your IP is not blacklisted, however emails still hit the Spam folder, contact support of a mail service to remove your IP address from their blacklists:

    Hello,

    I have setup Plesk Control Panel at a custom url (ps.mydomain.com) using the "Custom Plesk Hostname" extension.

    Where do I find the dkim _domainkey.ps.mydomain.com to use in mydomain.com DNS to validate the email source?

    Hello, mydomain.com will have dkim like _domainkey.mydomain.com. DKIM is based on domain name, not Plesk URL. If DKIM is enabled you will see it under Website & Domains > domain.com > DNS settings.

    Hello Anton, I apologize I wasn't clear in my question.

    All the websites I host on Plesk send emails through Mailgun and have the proper SPF and DKIM setup.

    Plesk Control Panel is setup at a custom url (ps.mydomain.com, a subdomain of my company domain), I did that using the "Custom Plesk Hostname" extension.

    Now, all notification and warning emails sent by Plesk are sent from ps.mydomain.com, which is Plesk itself and not a website/property/application/domain hosted there.

    I am looking for its DKIM, something like : key._domainkey.ps.mydomain.com

    Hello,

    As ps.mydomain.com is a subdomain of a company domain, then DNS TXT record intended for DKIM like key._domainkey.ps.mydomain.com should be configured in the DNS zone of 'mydomain.com'.

    However, in this way, Plesk is not aware of the customized domain used for outgoing notifications, thus it would not be signed properly by Mail server.

    Hi,

    DNS is hosted with the registrar for most of the domains on my server.

    Are the steps you outlined in the article the same for a domain where the DNS is NOT hosted with PLESK?

    ex:
    myserver.myserverdomain.com hosts the website
    clientdomain.com is the site being hosted
    clientdomain.com is dns is hosted by godaddy.com

    The dns records I added are:

     

    Is this correct?

    I do not host email for any of the sites.
    1. Do I still select DMARC and DKIM at the server level in the mail server settings?
    2. Since mail settings at the domain level on PLESK are deactivated, can/do I still select DKIM?
    3. For the DNS records mentioned, where did the string of characters come from - it looks like a key?

    Thanks!

    Hi Daphne Talbot

    >Are the steps you outlined in the article the same for a domain where the DNS is NOT hosted with PLESK? 

    If an external DNS server is used for a domain, make sure that all TXT records related to DKIM and DMARC (default._domainkey.<example.com>, _domainkey.<example.com>, _dmarc.<example.com>) from domain's DNS settings are transferred to external DNS as is.

     

    > 3. For the DNS records mentioned, where did the string of characters come from - it looks like a key?

    The key for DKIM can be obtained as follows if the DNS is external:

    https://support.plesk.com/hc/en-us/articles/115000214973-How-to-get-the-DKIM-public-key-from-Plesk-if-DNS-is-not-installed-

    However, since you have mail hosted externally you need to activate SPF, DKIM, DMARC on your mail server and generate the key there.

    After that you should be able to adde the records on the DNS server. Enabling on Plesk will not make any difference.
