Often, I receive "spoof" emails that purport to be from a reputable source (i.e., Fedex) but actually come from a malicious sender. This is easily seen by checking the sender's email address (usually outside the U.S. with an address that's letters and numbers, or a misspelled version of an actual domain). I am running Thunderbird 78.7.0. My mailbox displays the sender's name, but not the email address. This is true for ALL senders, whether or not they're in my address book. Is there any way to display the sender's email address? Thanks in advance for any help.
