" SMTP Debug: CLIENT -> SERVER: URES -- IP TEMP BANNED 
SMTP Debug: CLIENT -> SERVER: lk><br>Error: last request failed: [AUTH] LOGIN DENIED -- EXCESSIVE FAIL"

I'd suggest the user/pass is wrong for the mail account, and the IP was banned after it tried a few times. Seeing only partial error messages makes it harder to be sure, but that's where I'd start looking.

Sorted, Thanks lot/ . not password server configurations getting wrong.
