The AOL postmaster team posted some information about the upcoming MX transition on their blog. [S]tarting this week, the majority of AOL’s MX records will point to [OATH’s] new combined servers. This should be transparent to any sender as those servers will operate in simple pass-through mode. This means senders with established FBLs will continue […]
One of those $5.00 words I learned in the lab was gestalt. We were studying fetal alcohol syndrome (FAS) and, at the time, there were no consistent measurements or numbers that would drive a diagnosis of FAS.
