Two aspects to it:

1. Sympa can handle multiple domains (see the documentation for "virtual 
robots")

2. The machine sympa runs on has to be an appropriately configured mail 
host for each domain you support (MX records, SPF records, and so 
forth).  That's just mail handling 101 - you have to be able to receive 
mail for a domain you're serving, and you have to be able to originate 
mail for that domain.  (Actually, you can always forge return addresses, 
but a lot of your mail will be intercepted by spam filters.)

What I do for several domains:

- set up our a separate machine name for list handling in that domain 
(e.g. for domain foo.org, use the name lists.foo.org)

- set up all the appropriate DNS records (MX, SPF, PTR) for 
lists.foo.org, to point to the machine running sympa (note: this 
pre-supposes cooperation of  whomever  manages nameservice for  the 
domain, as well as whomever manages PTR records for your IP address)

- set up your machine's MTA configuration files to receive and send mail 
for lists.foo.org

- set up a virtual robot in Sympa to handle lists for lists.foo.org, 
along with the necessary aliases

- set up your lists

and away you go.
