Does identifying an email as 'Junk mail' automatically block future emails from this source?
I have some questions about Thunderbird email. If an email is suspected as being 'junk' do I just delete the email and will future emails be blocked from that sender? I don't actually open the email.
Related to this, I usually 'unsubscribe' from marketing emails, but when I click on the 'unsubscribe' many ask for my email as "verification". Why? They HAVE my email to which they've just sent their junky marketing info. I don't usually respond. So how can I unsubscribe without sending my email address, which they already have. If I just see it is marked as 'junk', and I just delete without opening it, is this as good as "unsubscribing"? Is this request for my email necessary or a phishing scam?

Most emphatically not. See https://support.mozilla.org/en-US/kb/thunderbird-and-junk-spam-messages
As the email you are unsubscribing from was sent to the email that are asking for, I see no issue.
Certainly good unsubscribe links embed the email address in the link you click, but at some point the sender has to know what email address to stop sending mail to. Others like groups.io will remove you from a mailing list with a single click. But I think if you want to stop getting mail. Entering the email it was sent to, while somewhat onerous, is simpler than trying to suppress future email via a mail client.
While there used to be some sort of urban story about confirming your email address exists if you enter it in unsubscribe links fundamentally the real spammer simply do not care if the email addresses exist. Some even send mail to random addresses in the hope they hit one that does exist. Their clicks per email send are almost nothing but when you send 500 million email almost nothing is still quite a substantial number. Those senders rarely offer an unsubscribe link, even where is is a legal requirement. One thing that is generally overlooked is when an SMTP server tries to deliver an email to the email address. The receiving server will refuse mail for many reasons, one of those reasons is the email address does not exist on that server. So if the marketer was interested in knowing which of the addresses they sent email to, they would simply log the send failures.
Legislation, in the EU and Australia, that I know of requires marketing mails to have an unsubscribe links. Google has come on board requiring the links in what they consider bulk emails. The result is that the vast majority of unsubscribe links now function as advertised and are not some sort of honey trap for harvesting email addresses. But not of the legislation requires it to be a single click and done. Hence the ask some questions in the hope folks will abandon the idea. It obviously working with you up to now.
