Backup \ alert emails are coming from the wrong address

I have specified a specific email address in the "From: address for email sent by Virtualmin" located in system settings - module config - actions upon server and user creation, but the emails are still coming to us from "webmin@localhost.localdomain"

Which probably isn't a big deal, but we're trying to capture these emails in a trouble ticketing system and it's creating problems.

Any ideas? Thx
