Rather than using that, use gmail. If you add periods or a "+[numer]" to the end of the email, its identified as the original email.
for example, say i have this email origially: Kappa@Gmail.com
If i need a new account, I can do:
K.appa@Gmail.com
Ka.ppa@Gmail.com
K.a.p.p.a@Gmail.com
Kappa+1@Gmail.com
Kappa+2@Gmail.com
K.appa+1@Gmail.com
All these are the same Kappa@Gmail.com
