Multiples. It wasn't a standards issue, but rather a string-length issue, I
think.
So I started poking around some more on the web to try finding this info,
and came up with this page:
http://www.emailaddressmanager.com/tips/email-address-limit.html
It seems that most of the providers listed have a 100 addressee limit. Also
found a reference that OE had that limitation as well. That is obviously
way, way over my 255 character limit.
Also found that a couple of RFC's
(
http://tools.ietf.org/html/rfc3696#section-3 summarizes these) limit the
address to 64 characters in the "local name" part (your "gary" for example)
and 255 characters in the "domain name" part (your listed "NoMail.invalid"
part). Perhaps that domain name part is what I recalled instead of the
whole address string having that limit.
Oh, well; learned a bit anyway.

I don't know, but if WM has a limit, it would only be for the purpose
of conforming to the international standards for email.
Are you talking about one email address, or multiple email addresses
in the To: line?
