I finally figured it out.
my response 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
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
basically having more than one account of gmail on a router will make the router start blocking gmail because gmail uses different ports for email (465 and 995)
it also solve a lot of people having this problem as I posted this answer a few time on the net. all people with multiple gmail accounts and a router seemed to have this problem.
anybody know how to contact gmail support to tell them this? hundreds of people has ask this question
