Suppose I have the following in my 'bofh' file:
Does the 'mailfromok' option have any effect here? In other words, does
it mean anything when 'all' is also set?
No substantial effect, except that the From: check is skipped, so the
Received-SPF: header for the From: check does not get generated.
Also, in this case, are the contents of the third 'Received-SPF' header
affected by the presence or absence of 'mailfromok'?
Yeah, it will not be generated.
