The one other thing you'll need to do if you haven't already, is 
configure the receiving machine so it will accept network mail. Fedora 
and current RH versions ship with sendmail configured to only listen on 
the localhost loopback which is pretty useless for a nework mailer.  In 
sendmail.mc on alfred, remove the 127.0.0.1 from DAEMON_OPTIONS entry so 
it looks like:
DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
and make sure port 25 isn't firewalled. Also make sure that alfred has 
all the host/domain names you might use as target addresses in its 
local-host-names file.  There are other ways to explicitly force mail to 
go to a certain machine (local DNS with explicit addresses, forwarding 
files with explicit addresses, mailertable entries mapping to IP 
addresses, etc., but MAIL_HUB is intended for use where you have more 
than one internal machine and you want all local mail to go to one of 
them.  If you also do internet mail you can configure this one to relay 
and be the SMART_HOST for the others, perhaps with address masquerading 
but they are separate concepts.
