email from internet to applelink

[timmer@dutiag.tudelft.nl (I. Timmermans)]

Can anybody tell me how I can send email 
from Internet to applelink and vice versa? 
I know the procedures for sending mail from 
compuserve to internet and back again. 
It seems logical that this is possible 
for applelink too. 

Thanks in advance
