On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Emails sent from external mail services are rejected by DMARC checker on a Plesk server: REJECT message for jdoe@example.com

    The instructions of making non_smtpd_milters empty contradicts with https://support.plesk.com/hc/en-us/articles/214528265-Plesk-Premium-Antivirus-does-not-detect-infected-emails. So what should we do now?

  • Hello b_p,

    It depends on what error/symptoms you have.

    In order to investigate it, you might try it first or open a support request.

    As a follow-up, this was mainly a comment, that your documentation is contradictory: here you state that non_smtpd_milters shall be empty while you recommend the opposite in the other article.

    Also, given that the issue described here refers to incoming e-mails (which should be delivered through smtpd), the non_smtpd_milters should not affect this process at all? But as this would disable scanning e-mails that are sent from scripts for instance, I assume the advice in this article should be adjusted?

    Hello @b_p,

    "non_smtpd_milters" was used in old unsupported Plesk versions. Currently Plesk do not use and do not configure it anymore.

    "non_smtpd_milters" must be empty. 

    I have corrected https://support.plesk.com/hc/en-us/articles/214528265 

    Plesk uses its own custom sendmail-wrapper which already uses mail handlers stack for this reason "non_smtpd_milters" is not needed.
