Are you saying that from the same machine you did "nmap -sT -F -P0 -O xx.xx.xx.xx" and got a report including "SMTP port 25 open" and "POP3 port 110 open", and also doing "telnet xx.xx.xx.xx 25" gives no response? That makes no sense, because nmap -sT means a full TCP connect - the same as the telnet command would do. Please confirm whether I am understanding correctly that you are doing both these tests from the same machine to the same address and getting different answers?
