This just started last week: when I send an email with an attachment, it no longer shows up in my sent box, or my drafts box, which had always automatically happened. I went through the Disk Utilities drill, but it said everything was ok in both Permissions and Disk checks. Does anyone have any ideas of what to do? fyi: I have a fully loaded 2013 iMac with 10.9.5 OS X (Mavericks). I've been avoiding upgrading to Yosemite....would that help this situation if I did?
