delivering local mail

I'm running a server 'abc.server.com'. The MX record for 'server.com'
points to 'mail.server.com'.

However, when I use SMTP on 'abc.server.com' with a RCPT TO:
'user@server.com', it returns 'local user unknown.'

How to I tell Sendmail that email going to 'user@server.com' should go
to 'mail.server.com'? And of course, truly local mail such as 'root'
should go to 'abc.server.com'.

Try this (from cf/README):

confDONT_PROBE_INTERFACES DontProbeInterfaces
[False] If set, sendmail will _not_
insert the names and addresses of any
local interfaces into class {w}
(list of known "equivalent" addresses).
If you set this, you must also include
some support for these addresses (e.g.,
in a mailertable entry) -- otherwise,
mail to addresses in this list will
bounce with a configuration error.
If set to "loopback" (without
quotes), sendmail will skip
loopback interfaces (e.g., "lo0").
