I just recently purchased a new laptop. It is connected to the internet through a wireless router. I am able to connect to the internet and I can receive email, but I can not send it. I always get a message saying "server rejected the senders email address" My other computer continues to send email as it always has. That one is not hooked up wirlessly. I have checked my settings many times for mistake,and I have not found any. I checked with verizon and they claim the problem is not on their end. Thank you in advance for any help given to me!
