Giving the following scenario :
- my SME 6.0 hosts domain1.com and domain2.com
- I ask my ISP to create MX records for both domains pointing to the same SME
- now, at domain1.com they want an e-mail  john@domain1.com  
- but  at domain2.com  they also want a john@domain2.com
If I create a user account "john" ,  mails to domain1 et 2 will be delivered
to the same user ? Right ?
I guess that I have to create 2 accounts for each customer like  for ex:
"cust1-john" et cust2-john" and then....what ..? create e-mail aliases ?
Any idea ? Best practices ?
Thanks
