e-mail services
Just to add to the subject, chances are that e-mail server at Verizon experienced fatal problems. This does happen to large IPs no matter what you thought before. Also, I do not know in the DR, but most U.S. companies allow one generic e-mail providor, to narrow hacker access and have more control on employees and the information they send out into the public domain. The generic e-mail of choice for corporate America is Yahoo. Instituions in the New York finacial distric prefer Yahoo as opposed to any other (Hotmail or otherwise).
