Issue [email protected] keeps sending e-mail notification even if i've edited panel.ini file.

[Goddari]

Server operating system version

Windows Server 2019

Plesk version and microupdate number

18.0.60

My configuration:
Windows Server 2019 acting as webserver (iis) + openrelay (mailenable) for websites email, on the same server open local smpt that send to an authenticated webrelay the email of all the websites hosted.
All'email works fine and reach out the destination. EXCEPT the scheduled activities notifications, they fail auth on the webrelay cause the sender email is not valid (of course is not, plesk presents itselft to the webrelay as [email protected]), so my webrelay says failed auth and drops the email.
I've spent hours trying to fix that, i've edited the panel.ini file addding a valid mail address, but plesk keeps presenting itself as postamster, this behaivour is only related to scheduled activities.

I will give you part of the log of my webrelay

Good question. Unfortunately I not sure what would cause email still to be sent as [email protected]. I suggest contacting Plesk support for an investigation. To sign-in to support please go to https://support.plesk.com

If you bought your license from a reseller, your reseller should provide support for you. If the reseller does not provide support, here is an alternative:
