Greetings, Apologies if this isn't the appropriate forum. Recently (over the last six months?), Verizon has blocked smtp requests on port 25 to our mail server hosted on our machine (brama.com). It seems that this isn't just our box, but a policy that Verizon has implemented widely, forcing Verizon patrons to use someuser@xxxxxxxxxxx to send outbound email, or use a different port (587?). More recently, recipients with @verizon.net cannot receive emails from our hosted domain names. As yet, I only have bare knowledge with the indication that the Verizon problem rests with finding an answer at the following website: Sender Policy Framework http://www.openspf.org/ I recognize that I need to learn more to fully understand this matter. Would anyone have any recommendations on where to research this further and why these policies are being implemented. Much thanks in advance.
