[MM3-users] Configuring sendmail without virtualtable? Is this possible?

I'm presently running mailman 2 on an email server, which all use @psfc.mit.edu addresses.  And which uses /etc/aliases.

The directions for configuring sendmail for mailman 3, specify using virtusertable.

I want my new email server to also host mailman 3 on ubuntu.  Is it still possible to use sendmail,  given the following directions for sendmail configuration?   Seems talk using might break things.   Or am I wrong?
