R: [OT] How to avoid Backscatter in Sendmail

[Marcello Anderlini]

This is a production server with a lot of virtual users and virtual domains,
I'm afraid that If I disabling relay_based_on_MX the system could be stop to
process all email.
Could I just disable relay_based_on_MX or I have to had some other feature
to allow relay for virtual domains and users ?

Thanks again
