Can I get new requesters to be automatically be added to an account based on their email domain

Hi,
 
 
Can I get new requesters to be automatically be added to an account based on their email domain.
 
For example if  a new person who is not currently setup as a requester sends an email to helpdesk@msp.com .
 
Eg
 
I want from address of name@cust1.com to be created in the cust1 account common site.
or any new requesters from @cust1 to be created in the cust1 account common site.
 
I want from address of name@cust2.com to autobe created in the cust2 account common site.
 
we have many customers that we provide support for but dont have a list of all their potenital requesters.
 
Thanks
