I get most of my emails from my ISP email account but not all of them. Don't know why. Went to Verizon store and they told me it was a problem with my ISP and call their tech support. I called them and they said it was a problem with the Droid 4 email client that was blocking some emails and allowing others. No particular pattern identified regarding which emails get through and which are blocked. This is the closest situation similar to my own. Has anyone else had this issue with a few emails not getting through the droid 4 email client? Any suggestions on how to adjust the email client settings. Does it have any type of security or spam blocker that I have not been able to find? Could use any assistance. Deleting email account and reinstalling has not helped. Never know when I have not received all my mail until someone calls me to complain that I have not responded.
