Topic: email keeps me up at night

[david erdman]

i am really confused.  I have two domains.  www.foo1.com, and www.foo2.com.
foo1 is the primary website, foo2 is the virtual domain i have setup.  The websites work great.  
I have 2 users ed, and ted.   ed uses foo1, and steve foo2.  so ed@foo1.com, and steve@foo2.com

Do I need to point both MX records to the primary domain foo1 (mail.e-smith.foo1.com)?  or does each MX point to its individual (and virtual) domain?  The documentation is not helping me at all....
i just want to setup pop accounts for each domain.

for each individual outlookexpress account, i have setup the pop3 server.
ed has mail.e-smith.foo1.com for his pop3, likewise for smtp
steve has mail.e-smith.foo2.com for his pop3., likewise for smtp

however no mail is being delivered...i have the email settings on public also.  
hopefully i have provided enough info to clarify my problem
