Install without prompts

[Peter]

Is it possible to install MailScanner and bypass the prompts or feed the
answers somehow?

I am scripting building a server and it's a pain that I always have to come
back and answer the questions about TNEF, cpan etc. then wait for another
while mainly for the cpan stuff to happen.

Which raises another question, is there a repo that has more of the
required perl modules for RHEL 8?

Cheers.
