Unable to trigger the mail notifications from Company's Mail ID

Hi All,

We are sending mail notifications through custom mail template with schedule tasks.

Recipients are getting the mail from sender instead of company mail address.

For Example:

1) If owner adds collaborator mail is triggering in such a way that owner is sender
2) when we run any schedule task with run as user as "X" then mail notification is getting triggered from X mail ID.

The above two issues we are facing after upgrading our verion from 9.0.14 to 10.0.4

We set the system property and chekced but still facing the issue

messaging
messaging.mail_source_policy
SENDERS_COMPANY

Kindly help us in triggering the mails to recipients from company mail address.

Many Thanks!

Santhoshi.
