May I have your attention please...

hot_yummiee@yahoo.com IS one of my email addresses.
hot_yummiee@yahoo.com IS NOT the contact email of a porn site.
hot_yummiee@yahoo.com IS one way of reaching me, not the hot girl on 1-800-ucallme or whatever it is

Now here is how you'd define these words...
hot: adj sharply peppery or pungent; spicy

yummiee is not listed in the dictionary

But...
yummy: adj very pleasing to the senses, esp. to the taste; delicious: The waiter brought out a tray of yummy desserts.

Thank you.
