The *_these_nonmembers lists are lists of plain email addresses without
comments or real names or regexps (beginning with ^) that match email
addresses.

Actually, config_list input is Python, and in Python it is perfectly
acceptable to break a list like the above across lines. New-lines
outside of quoted strings are ignored if they occur inside parens (),
brackets [] or braces {}.

With the above, user3 at example.com could not post (because the code
would test whether 'user3 at example.com' is equal to 'user3 at example.com
(Joe Bleaux)') but the others could.

It's not valid and your expectation is reasonable, but this isn't what
happens (I'm not saying it can't/won't be fixed).
Here's a section of the code that would normally validate the supplied
value.
if wtype in (mm_cfg.EmailList, mm_cfg.EmailListEx):
# BAW: value might already be a list, if this is coming from
# config_list input. Sigh.
if isinstance(val, ListType):
return val
In other words, if accept_these_nonmembers (or any attribute which is a
list of email addresses or a list of email addresses and regexps)
comes from the GUI page, it is the contents of a text box which is a
string and it is validated and transformed to a list, but if it is
already a list, it is assumed to be from input to config_list and the
list is just assigned to the attribute without validatating its
contents.
If you want to see this fixed, the best next step is to report it in
the bug tracker at
<http://sourceforge.net/tracker/?group_id=103&atid=100103>. (Since
I've already done the analysis, I'll probably fix it, but get it in
the tracker anyway.)
