question about e-card


I just set phpalbum up on my home server 2 days ago and it works wonderful.
Thank you for your FREE and nice php album script and can't wait to see new version come out. So far, i have difficulty to get e-card to work and here was what i did:
I created a new user - let's called it "user1" then I login as user1 and wrote a e-card to admin. ( of course, both user1 and admin use 2 different email address). However, admin never receive e-card from user1. is anyone know how to get this to work please let me know? thank you so much.
