Hi
I am a home user and use SMTP Proxy with ISP as SmartHost to send my mails.
I do Not have any e-mail server internally.
During the 6.x era, it is easy to just enable AV and AntiSpam + Smart Host and port scan shows all ports closed on GRC which is preety solid.
As for home users with no servers, that should be the way.
Ever since the 7.X Era this changed as the following ports would be opened.
Port 25,
Port 465
Port 587
Before the 7.3 ERA, it is a must to specifiy a domain so I just type some tyutytuytuytuy.com as the domain and point it to my print server IP Address all just to keep it enabled else it won't enable.
Now I upgraded to 7.3, I hoped to further lock down my SMTP Proxy but I am still stuck.
1) SMTP Simple Mode.
2) Routing, I changed to MX Records and leave the domain empty, I hope this is Better than the uyuiyuyiuyu -> print server configuration.
3) Relaying, I allowed my LAN Network and SSL VPN
4) Blacklist = ANY ( I enabled this to further block it, hope I do correct)
With the above settings, my idea is ANY Inside Allow go to my ISP, any outside DENY and dun even see the ports.
I did a port scan and the same ports remained open.
Please advice how I can further lock it down?
I did not specify in the packet filter as I hope this is part of the SMTP Proxy configuration, if no server, no open ports.
Thank You for all advice [H]
