Thank you, Dom Mitchell and T. William Wells.
So far I still *not* get my filter to return *true* as expected.
It may be a BSDI 2.1 or Exim 1.62. or a Tim issue. I am a
beginner+ to pattern matching.
The facts seem to be as follows:
#the email message contains the following in the header
From: 1234@???
#!exim filter
Observed results using exim -bf spam_filter < test.msg
True $h_from: contains global
True $h_from: matches global
False $h_from: matches 'global'
False $h_from: contains 'global'
False $h_from: matches \b[0-9]+@.*\.com\b
Error $h_from: matches ^[0-9]+@.*\.com$
False $h_from: matches ^[0-9]+@.*\.com
Error $h_from: matches '^[0-9]+@.*\.com'
Thank you,
Tim Patterson

You are misunderstanding regular expressions. You should try this one
instead:
^[0-9]+@.*\.com$
