I've got an instance of sendmail listening specifically on 127.0.0.1 ... can anyone point me to some information on how to disable synchronous dns verification in sendmail?

The TUNING file in the sendmail directory of recent sendmail versions is well worth reading.

I find it simplest to put the following in my sendmail mc file: DAEMON_OPTIONS(Name=MTA') DAEMON_OPTIONS(address=localhost, Port=24, Name=NCMSA, M=EC')

And then have mailman deliver to localhost, port 24.

Normally, sendmail will attempt to canonify the hostnames of each address Mailman submits to it--this requires a DNS lookup. The 'C' in the M (Modifier) option disables canonification. This is safe to do for mail injected by Mailman, though it is not something I would recommend for incoming mail. Port 24 is reserved for private mail systems so it seems like a good fit. And it's only listening on localhost anyway.
