Hi, I noticed that after I upgraded to El Capitan my Mail program showed practically NO mail messages in the "inbox" folder. I gave the "rebuild" command and it seemed to fix the problem. Now I'm noticing that it's NOT fixed AT ALL. A few weeks ago I received an email that I intended to answer back in a few days. Then I did the latest upgrade to 10.11.1 (just a coupla days ago) Today I decided it was time to answer that email... guess what?? NOWHERE TO BE FOUND!!! I did also a search with Spotlight... NO RESULTS! Not even in a remote folder. As it never existed!!! That's a SERIOUS issue. I asked the sender to mail me back the stuff again, but you can see this is a MAJOR flaw. Any suggestions? A'
