That is one way to do it, but requires that the POP server also know about 
domains (which can be painful).  My preferred method is to have the mail go 
to a different account name that fits into the normal Unix account name 
scheme.  Then use a choice of POP and IMAP servers without needing any 
special setup.

Use LDAP to store the account info, this will also make it easier for you 
when you want to expand to multiple servers.
