[Mimedefang] Revised Spam Rule for Bad AOL Addresses

[Kevin A. McGrail]

After looking at the results this morning, I realized that Kelson's filter
was stripping angle brackets.  Therefore, his test could match beginning and
end-of-line efficiently and so I have modified the test below to remove the
previous end of line check in the regexp's.

Any suggestions would be appreciated as I believe I'm really close on the
rule but not perhaps 100%.

wordwrapping will make the posted version difficult to use.
