[Lnc-business] new LNC-Business email delivery problems

[Alicia Mattson]

Just as an update on this issue, I have not seen any further instances of
delivery problems from our email list to the Gmail users.  It still happens
routinely for the Yahoo/AOL users, but I have only seen it that one time
for Gmail.
