[Mailman-Users] Sendmail performance

[David Gibbs]

Folks:

The README.SENDMAIL has the following statement ...

> Since Mailman usually connects via localhost (i.e. 127.0.0.1) to
> the SMTP port of Sendmail, you should be sure to configure
> Sendmail /not/ to do DNS verification synchronously for
> localhost connections.

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?

Thanks!
