Confused by no mail showing up

[jim007]

When I select contact everything works like it is supposed to, fields, captcha, and successfully sent... but no mail shows up. Is there something in the code that I have wrong? Please liberate my brain! I fried it trying to figure this out. I know it is something simple that I am over looking also. thank you in advance! and I do apologize for my lack of knowledge of this but I am trying (old dog - not good with new tricks)
