[Mimedefang] Process SPF checking for certain recipient domains

[Jon Rowlan]

I have been looking though k/b articles but can find no real help on
whether its possible to SPF check certain recipient domains?

I would like certain domains that we accept mail for to use SPF but not
on others.

Is the only option to install an SPF sendmail/MD server and a separate
non SPF one?

Does anyone have any thoughts or ideas on this please?

Thanks all
