I received an email today (8/12/2018) that appears to have been sent on MAY 5 of this year.
I ran MailWasher as usual and saw this unusual email. Mailwasher wouldn't open it. Fine. I opened Thunderbird, and it did not appear in today's emails.
I opened my Earthlink mail account (that's the address it was sent to) and there was the email - no spam, nothing attached, no problem...except that it was apparently sent on May 5.
What the heck is the deal with THAT and the other dead ends involved in this mess?
