Since I've replaced my netgear 834 router with a 2820vn I cannot send emails. More precisely, I was able to send one email, but was unable to send another two...
First I thought it's not due to the new router, so restarted yahoo, but no difference; started in different browser: no change; restarted laptop: no change. So my guess is that it's something to do with my new 2820vn router's firewall or other settings... :?

Any suggestions would be much appreciated!
Thanks
