AOL says the problem arose late last week when Yahoo did not notify AOL that it had changed its IP addresses on some of its servers, including those that have the Yahoo Groups emails.
Because AOL was not notified, the company's servers identified the mail coming from Yahoo as spam.
"This has caused AOL users who are subscribers to Yahoo Groups to miss three to four days worth of emails," said Robert Neill Jr., a publisher and moderator of 80 Yahoo Groups.
