  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Protection from Outgoing Spam - Error

MoritzKK

New Pleskian
I have some error when the new outgoing spam protection (limitation for outgoing mail) is enabled. Mail clients are unable to use SMTP for sending mails. "My mail client says: The message could not be sent. You are not allowed to use sendmail utility."

I don't undestand the blocking behaviour since the checkbox "Allow scripts and users to use Sendmail" is checked and no limit is exeeded.

This is the relevant log part of maillog:
Code:

Moreover I disabled the line "non_smtpd_milters" in postfix main.conf since my server has same issues discribed in the following thread:
Postfix: mails sent through sendmail binary are blocked because of wrong HELO
