• 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.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

My Plesk server suddenly alerted me to a mass mailing via an account [email protected]. I went into the maillog file and saw that it was triggered by the following line:

Code:

As you can see, suddenly the incomming email [email protected] was changed to [email protected]

How could this happen? I have enabled the option ‘Correct incorrectly set senders for outgoing mail’.

It is very strange because my server received an email from an external email [email protected] to another external email [email protected] and my server has converted the sender to an internal email [email protected] and is trying to send it.

And that's exactly what it does.
Your user authenticated as [email protected], and then tried to send as [email protected]. Which was corrected to the address the user authenticated with.
