No, his e-mail address is that without the trailing ".INVALID".
I don't know how .invalid gets on the end but, it might have something to do with why you can't unsub.
This is unlikely, as it will not be present in the headers of the messages the user sends.
This is the Domain-based Message Authentication, Reporting and Conformance system (DMARC) at work; see https://en.wikipedia.org/wiki/DMARC . It is designed to detect some spam by identifying messages that do not originate from a genuine server for the domain in the From: header. The user's mail provider, yahoo.com, is one of those currently setting a "reject" policy for DMAC, so receiving mail servers should reject any message claiming to come from a yahoo.com address which has not originated from a genuine Yahoo server.
This is a Good Thing, but creates problems for mailing lists. Messages distributed by OpenOffice mailing lists retain the sender's address in the From: header but originate from OpenOffice's own servers, not from the original genuine server - in this case a Yahoo server - so receiving systems will identify such messages as spam and properly reject them. Most list subscribers, then, would not receive messages to the list from enquirers using Yahoo and some other domains. The workaround chosen by OpenOffice is to modify the From: header to disguise the originating domain and fool the receiving systems. If you wish to use the enquirer's address, you will need to remove the ".INVALID" part of the address.
Eagle-eyed readers will notice that my address falls into this category, as btinternet.com is Yahoo in disguise.
