The last 4-6 years ComodoFW has been my standard firewall as well as Opera for mail and browsing. And I am very satisfied with ComodoFW! Two weeks ago I reinstalled W7-64, and reinstalled Comodo and Opera.
4-5 days ago I could still downoad fresh mails but no sending… And I am rather sure this is because I made som changes under >Firewall, >Network Security Policy at that time. I changed the settings from “Use a Custom Policy” over to “Use a Predefined Policy” and selected “Web Browser”. After that I was not able to send mail. Today if I define Opera as “Email Client” (under >Network Security Policy) then I am able to send mail again. The problem is that I can not select both at the same time. And if I select “Use Custom Policy” then all the former settings are gone.
When I look at the rules for “Email Client” in relation to “Web Browser” under >Predefined Policies I can see that one line is missing for Web Browser; “Allow Outgoing POP3/SMTP Requests”. This must be the reason.
What’s optimal for security; make a complete copy of the settings for this point and add it as a general rule for “Web Browsers”? Or is it best to delete all settings for Opera under >Network Security Policy and define new rules by restarting Opera? Or what do you recommend?
