I just found the solution. my post to incredimail support

OK. Here’s the deal. Outlook and express both stopped working after a few hour or so. Thunderbird would not work. I concluded that gmail is the problem.

Outlook express did however produce an error code. I googled it and it seems that a lot of people have this problem. I immediate notice 2 thing people had in common. A router (most had this issue) and multiple gmail accounts. I am a bull head who refuse to quit when I have a problem so this what I did. The 2 account thing lead me nowhere (although I now suspect that the multiple gmail accounts lead to the router blocking the ports). So now I went after the router
I type in the router (192.168.x.xx). I then made 2 firewall exceptions in the router. 1 was called Mail Pop3 (with port 995 down as the beginning and end port and set to allow outbound connections) and Mail Stmp (with port 465 down as the beginning and end port and set to allow outbound connections).

Everything seems to work now.

Gmail has router issues
