Authentication is required for relay - runtask.exe

[gongcart]

I am using smartermail for my email server. All local mail delivery require relay is my setting due to security concern.

Problem:
The plesk runtask notification email does not have the option to enter email authentication data for authentication. Any work around? or is it possible that relay authentication can be added in the future version?

Error Message
runtask.exe
