email sign in failure

[Android Question]

My Galaxy 10.1 tab continues to block emails from various accounts-it is therefore of no use to me as I cannot rely on emails being delivered-sync is not WORKING- on the other hand I do get countless idiotic apps sent which I DO NOT WANT-can ANYONE correct this or do I have to sell it?

Sounds as if your accounts or your tab has been compromised (read: virus or Trojan). You need on-scene, not remote-via-forum, help - both to evaluate the problem and to fix it.
