Hello all. As you can see I am new here and I know little to very little about networking, etc. I use Comcast as my internet provider but have NO email account that I use with them. I am trying several email encryption programs and they are asking for SMTP settings. I have found what they should be. HOWEVER, I believe I am DHCP(?). When the computer starts it gets the addresses that it needs automatically. I have 3 email accounts and each one can be accessed via Chrome or Mozilla without any intervention from me. When I go into the SMTP settings boxes for these encryption programs I have entered, for example, smtp.gmail.com and tried smtp.comcast.net and the other settings and when I click "test" it fails. If I remember I get a message that says it CANNOT FIND THE SERVER...I have tried to find any network settings but in win10 it just has USE AUTO PROXY SETTINGS checked and that's it. So, I guess my questions is - can I use SMTP settings (in the programs configure box) when I am assigned my internet info by DHCP?? IF this is possible then HOW do I do it and WHERE do I do it? Thanks for any enlightenment on this. HAPPY HOLIDAYS to all!
