I have noticed that some e-mail addresses (notably @google.com) get .INVALID suffixed onto it so [email protected] become [email protected] in the From: header.
I have figured out that this is an issue with the way that our mail server is configured and opened https://issues.apache.org/jira/browse/INFRA-15529. For those of us that are impacted, it makes it more difficult for users to reply directly to the originator. Infra has asked to get consensus from PMC members before making the change which I figured it would be easiest with a vote. Please vote: +1 Update mail server to stop suffixing .INVALID -1 Don't change mail server settings.
