The issue is that Gmail is forcing your From: address to be the same as your authenticated identity (to avoid spoofing).
You can add extra verified E-mail addresses to your Gmail account, and then you will be able to send using those as well. It's in Gmail settings somewhere. Beware that if the domain "org.com" is using SPF, then its SPF record in the DNS needs to allow outbound mail from Google's servers. If org.com is already Google hosted that's fine - but then you'd be better logging into Google with an org.com GSuite account. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
