Mail not working error (ec=56)


Sorry for my english because it’s not the best but i will try to explain me.

I’m trying to set up my email configuration but it always fail with the error “Failure when receiving data from the peer(ec=56), response reading failed” when i try to test it.
My configuration is:

Mail server username (empty for none):
Mail server password: XXXXX
Sender E-Mail Address:

And it always return me the same error i don’t know what to do i red all the other posts and nothing helped me.
