Since Sept 15, 2013 I cannot send emails, but I can send them

I am on a Norwegian cargo ship off the coast of Norway. It has Wi-Fi, but I cannot send emails using my iPad. I understand that Verizon has had big problems recently. I cannot phone Verizon for advice, and if the problem is Verizon's fault, I do not want to change my settings. Can anyone advise me how to fix the problem? Very frustrating and I have not been able to reach technical support using my Safari browser.
Sincerely, W. E. Howard
