The at scheduler is emailing an unexpected user consistently on both old RHEL6 boxen and new OEL7 boxen when the jobs produce output or when the -m flag is used.
If we log in to the box with our individual user accounts, then use sudo su - to switch to a different account and schedule jobs as that different account, at sends email to the user that logged in to the system initially rather than the (effective) user executing at.
Is there a way to change the environment such that at instead emails the effective user?
Of note from the man page:
If at is executed from a su(1) shell, the owner of the login shell will receive the mail.
