Issue Scheduled Tasks and MailEnable - Send email when fail

[Frank.P]

When Plesk send email use default postoffice or email adress like [email protected] to the email set in Scheduled Tasks.

If in MailEnable is checked "Autenticated sender must use address from their postoffice" Plesk can send email and Windows Evenets register

SMTP Exception
   at send mail from runtask to [email protected](runtask::start line 232)
   at (runtask::start line 240)
   at Unable to execute event(runtask::start line 250)
Execute file name: C:\Program Files (x86)\Parallels\Plesk\admin\bin\runtask.exe

This error is because Plesk want to send email from [email protected] to [email protected]

mydomainpanel.com is not the same domain of mydomain.com and mail server return

551 Sender address is not valid for your login. Check your email program settings.

Any suggestion fo solve this and using "Autenticated sender must use address from their postoffice"?

1- Make sure that IP address of the external SMTP server is added in the hosts file.


2- Disable Authenticated senders must use valid sender address feature in MailEnable Administration console > Servers > Localhost > Connectors > SMTP Properties > Security tab.


3- Enable Allow Relay For Privileged IP Ranges and ensure, that 127.0.0.1 is listed in the Privileged IPs list.
