Multiple Users

[Jonathan Tripathy]

Hi there,
 
Does postfix support multiple users using aliases? 
 
Example:
 
sa...@domain.com <mailto:sa...@domain.com>  would send the mail to 
us...@domain.com, us...@domain.com, us...@domain.com
supp...@domain.com would send the mail to us...@domain.com and us...@domain.com
 
My aliases table and user database is stored in a MYSQL database.
 
May this task is more suitable for a mailing list program
 
Thanks
