Obviously, the TCP-SYN packet to port 25 never leaves your network. You
can confirm this my tsharking your outer-world interface on 192.168.1.1
for "tcp and port 25" while trying tcptraceroute again.
I that case, you should yell at your firewall admin for dropping those
packets and not putting out an ICMP port-unreachable or a TCP-RST.
If packets are visible on that device, then the first hop i.e. your
provider drops them without returning a proper ICMP port-unreachable or
TCP-RST. In that case, you should yell at them.
