I haven't tested it or checked thoroughly the syntax, but I think
that the expression I gave (I replaced " " with "\s" although I think
they are equivalent):

${if match{$h_from}{^From:\s*(.*)\s*<}{$1}{}}

applied on a $h_from of the form "From: xxx yyy <..." will return "xxx yyy".
Of course if $h_from does not start with ^From it will return the
empty string (that is the content of the last set of braces {}).
If $h_from is of the form " xxx yyy <..", with optional whitespace at
the beginning and before the <, then your match would be:

${if match{$h_from}{^\s*(.*)\s*<}{$1}{}}


You can test my expression using pcretest and giving the following RE

^(\s*)(.*)(\s*<)

this will return, as match 2, what my expression above returns.

So you would use one of the above expressions in place of ${something
that returns Marc Perkel}. You could use it as a lookup argument, for
instance.
